Who Can Sign Off a Title 24 Report?

Call (626) 365-1518 | Alternative Energy Systems

Who Can Sign Off a Title 24 Report depends on which compliance document is being signed and who is legally responsible for the building design. A Title 24 consultant may prepare the energy calculations and compliance documentation, but preparing the report does not automatically make that consultant the person legally responsible for the architectural, mechanical, electrical, or overall building design.

For a California Certificate of Compliance, there are generally two important roles to understand: the documentation author and the responsible person.

The documentation author signs to certify that the compliance documentation they prepared is accurate and complete. The responsible person signs to accept responsibility for the applicable building or system design and certify that the design conforms to California’s energy requirements.

Depending on the project, the responsible person may be an architect, engineer, contractor, builder, designer, or another person legally eligible to accept responsibility for the applicable design scope.

The correct signer therefore depends on:

The type of building
Whether the project is residential, multifamily, or commercial
The scope of construction
The specific compliance form
Who prepared the energy documentation
Who has legal responsibility for the building or system design
Whether the project requires a licensed design professional
Whether field verification or acceptance testing is required

Alternative Energy Systems provides Title 24 energy calculations and compliance-documentation support throughout California. AES brings more than 30 years of California energy-compliance experience to residential, multifamily, mixed-use, and commercial projects.

Call (626) 365-1518 if you need help determining which Title 24 documents apply to your project and which project professional should sign them.

The Short Answer: Who Signs a Title 24 Certificate of Compliance?

The California Energy Code distinguishes between the person who prepares the documentation and the person responsible for the design.

For a Certificate of Compliance:

The documentation author signs to certify that the documentation is accurate and complete.
The responsible person signs to accept responsibility for the applicable design and certify conformance with the Energy Code.

These may be the same person in some projects.

On other projects, they may be two different people.

For example, an energy consultant may prepare the calculations and forms while an architect, engineer, builder, contractor, or other legally eligible responsible designer accepts responsibility for the design.

This distinction is important because a Title 24 consultant should not be described automatically as the person who can provide the final design-responsibility signature for every project.

What Does “Sign Off” Mean on a Title 24 Report?

The phrase “sign off” is commonly used by homeowners, contractors, and designers, but it can refer to several different actions.

Someone may be asking:

Who prepares and signs the energy calculations?
Who signs the Certificate of Compliance?
Who accepts responsibility for the building design?
Who signs installation documentation?
Who signs field-verification documentation?
Who signs acceptance-testing documentation?
Who approves the report at the building department?

Those are separate responsibilities.

A person who prepares a Title 24 calculation is not automatically responsible for construction.

A contractor responsible for installation is not automatically the building designer.

A field-verification professional does not automatically become the responsible designer.

The building department also does not replace the signatures required from the project professionals. The jurisdiction reviews the submitted documentation as part of the permit process.

What Is a Title 24 Documentation Author?

The documentation author is the person who prepares the applicable energy-compliance documentation.

That work may include:

Reviewing the construction plans
Identifying applicable energy requirements
Reviewing window and door information
Reviewing insulation assemblies
Reviewing HVAC specifications
Reviewing duct locations
Reviewing ventilation
Reviewing water heating
Reviewing commercial lighting and controls
Preparing energy calculations
Preparing compliance forms

The documentation author’s signature certifies the accuracy and completeness of the documentation that person prepared.

That signature does not automatically mean that the documentation author designed the entire building or accepts responsibility for every feature shown on the construction plans.

Can a Title 24 Consultant Sign the Report?

A Title 24 consultant may be able to sign the applicable compliance documentation as the documentation author when that consultant prepared the calculations and forms.

However, that does not necessarily mean the consultant can also sign as the responsible person for the building design.

The two roles should not be confused.

A consultant may:

Review the plans
Prepare the energy analysis
Prepare the compliance forms
Identify energy measures that should appear on the plans
Sign documentation as the documentation author

The responsible designer remains responsible for the building or system design represented by those documents.

Whether one person may serve in both roles depends on that person’s legal eligibility and actual responsibility for the applicable design.

Who Is the Responsible Person?

The responsible person is the individual legally eligible to accept responsibility for the applicable design.

That person certifies that the energy features represented by the Certificate of Compliance conform to the applicable Energy Code requirements and are consistent with the project documents submitted for permit approval.

Depending on the project and scope, the responsible person may include an eligible:

Architect
Professional engineer
Contractor
Builder
Building designer
Other professional legally permitted to accept responsibility for the applicable design

The correct person cannot be determined simply from a job title.

The person’s legal eligibility and actual responsibility for the design matter.

Why Are Two Signatures Sometimes Required?

Separating documentation preparation from design responsibility provides clarity about who did what.

The documentation author certifies:

The energy documentation was prepared accurately
The information included in the forms is complete to the extent required

The responsible person certifies:

Responsibility for the applicable design
Conformance with the Energy Code
Consistency between the design represented in the compliance documents and the project plans and specifications

On some projects, one qualified person may perform both functions.

On others, an energy consultant prepares the report and a separate design professional provides the responsible-person signature.

Who Can Sign Off a Residential Title 24 Report?

For single-family residential projects, the Certificate of Compliance is commonly associated with the responsible building designer.

The appropriate signer depends on the project and whether California law requires a licensed design professional.

Residential projects may include:

New single-family homes
Detached ADUs
Attached ADUs
Garage conversions
Room additions
Second-story additions
Major remodels
Envelope alterations
HVAC-related permit projects

When a licensed architect or engineer is responsible for the design, that professional’s information may be required in the responsible-designer portion of the applicable compliance documentation.

California law also allows certain residential designs to be prepared without a licensed architect or engineer. When a licensed design professional is not legally required, another eligible responsible designer or builder may be able to provide the responsible-person signature for the applicable project.

The specific project should be reviewed rather than assuming every residential Title 24 form must always be signed by an architect.

Does a Title 24 Report Always Need an Architect’s Signature?

No.

An architect’s signature may be appropriate or required when an architect is the responsible design professional, but an architect is not automatically the only person who can sign every Title 24 Certificate of Compliance.

The proper signer depends on:

The building type
The construction scope
The design professional responsible for the project
California licensing requirements
The particular compliance form being submitted

Avoid hiring an architect solely because someone stated that every Title 24 report universally requires an architect’s signature.

Instead, determine who is legally responsible for the applicable design.

Does a Title 24 Report Always Need an Engineer’s Signature?

No.

A professional engineer may be the appropriate responsible person when the engineer is responsible for the applicable design.

However, not every residential or commercial Title 24 report requires the same type of engineer.

For example, a project may involve separate responsibility for:

Architectural design
Mechanical systems
Electrical systems
Plumbing systems
Structural design
Energy compliance

The appropriate signature depends on which system or design scope is represented by the document.

Can a Builder Sign a Residential Title 24 Certificate?

In certain residential projects where California law does not require a licensed design professional, the builder may be eligible to sign as the responsible building designer.

That should not be interpreted as permission for every builder to sign every project.

The builder must actually be eligible to accept responsibility for the applicable design.

When an architect, engineer, or other professional is responsible for the project design, the responsible-person signature should reflect that responsibility.

Can the Homeowner Sign a Title 24 Report?

A property owner should not assume that ownership alone makes the owner eligible to sign every Title 24 compliance document.

The relevant question is not simply who owns the property.

The question is who is legally eligible and actually responsible for the applicable building or system design.

Owner-builder situations can involve different responsibilities depending on the project, permit scope, design, and applicable California law.

Confirm the responsible signer before submitting the compliance forms to the building department.

Who Can Sign Off an ADU Title 24 Report?

The signature requirements for an ADU depend on the design responsibility and the type of ADU project.

An ADU may be:

Detached new construction
Attached to an existing residence
Created through a garage conversion
Created through conversion of other existing space

AES may prepare energy calculations based on:

Floor plans
Exterior elevations
Building sections
Roof plans
Window schedules
Insulation assemblies
HVAC information
Ventilation
Water heating

The person responsible for the ADU’s building design should then provide the applicable responsible-person signature when required.

The energy consultant’s role in preparing the report should not be confused with responsibility for the complete ADU design.

For additional project information, review the ADU Title 24 page.

Who Can Sign Off an Addition or Remodel Report?

Additions and remodels often involve existing construction combined with new work.

The responsible signer may depend on who designed:

The new conditioned area
Exterior wall changes
Window alterations
Roof modifications
HVAC changes
Other systems included in the permit scope

The energy consultant can prepare calculations based on the proposed design.

The person responsible for that design remains responsible for the applicable responsible-person declaration.

This becomes especially important when the plans are revised after the original report is completed.

Who Can Sign Off a Commercial Title 24 Report?

Commercial and nonresidential projects can involve several separate design disciplines.

The energy documentation may address:

Building-envelope performance
Mechanical systems
Ventilation
Service water heating
Interior lighting
Exterior lighting
Lighting controls
Electrical-power systems
Other regulated systems

The Certificate of Compliance must identify the appropriate responsible person for the applicable design scope.

Depending on the project, that may involve a licensed architect, professional engineer, licensed contractor, or another person legally eligible to accept design responsibility.

Large or technically complex commercial projects may also involve additional compliance documents with their own signature requirements.

For professional support, review Title 24 compliance services and Title 24 energy analysis.

Who Signs Multifamily Title 24 Documents?

Multifamily projects can involve several categories of compliance documentation depending on building configuration and project scope.

The project may require coordination among:

Architects
Mechanical engineers
Electrical designers
Energy consultants
General contractors
Specialty contractors
Field-verification professionals

The person preparing a compliance document signs for the accuracy of that documentation when required.

The responsible person signs for the design, construction, or installation scope for which that person is legally responsible.

The exact signer therefore depends on whether the document concerns design compliance, installation, acceptance testing, or field verification.

The Certificate of Compliance Is Not the Only Title 24 Document That Gets Signed

A California project may involve several categories of compliance documents.

These can include:

Certificate of Compliance
Certificate of Installation
Certificate of Acceptance
Certificate of Verification

Each serves a different purpose.

The person who signs one category of document may not be the person who signs another.

Certificate of Compliance

This addresses the proposed design.

It is associated with the documentation author and the responsible person for the applicable design.

Certificate of Installation

This documents installed features, materials, equipment, or systems.

The responsible person for the applicable construction or installation signs the appropriate documentation.

Certificate of Acceptance

Certain nonresidential systems require acceptance testing.

The applicable acceptance-testing professionals and responsible persons complete the required documentation.

Certificate of Verification

When field verification and diagnostic testing are required, the applicable verification documentation is completed and signed by the qualified field-verification professional who performed that work.

These documents should not be treated as interchangeable.

Can an ECC-Rater or HERS-Type Field Rater Sign Off the Energy Report?

Field verification and design responsibility are separate functions.

A qualified ECC-Rater may perform required field verification and diagnostic testing and sign the applicable Certificate of Verification documentation.

That does not automatically make the rater the responsible building designer for the Certificate of Compliance.

The energy report may identify measures that later require verification, but preparing or signing verification documentation is not the same as accepting responsibility for the original building design.

This distinction matters on projects involving:

Duct verification
Airflow requirements
Mechanical-system verification
Other performance-sensitive energy measures

For related information, review Title 24 vs. CALGreen.

Does the Building Department Sign Off the Title 24 Report?

The building department reviews the compliance documentation as part of the permit process, but its role is different from the signatures supplied by the project professionals.

The jurisdiction may review whether:

The applicable forms were submitted
The required signatures are present
The project address is correct
The report applies to the current plans
The energy features match the construction documents
Required verification or acceptance-testing measures are identified

The building department may:

Accept the documentation
Request clarification
Issue correction comments
Require revised forms

Building-department acceptance does not replace the responsible person’s signature and does not guarantee that later construction or inspection requirements have already been satisfied.

What Happens if the Wrong Person Signs?

Incorrect or incomplete signatures can create problems during permit review.

The building department may request:

The correct responsible-person signature
The documentation author’s signature
Professional-license information when applicable
Corrected compliance forms
Clarification of who is responsible for the design

Do not simply move a signature from one person to another without confirming who actually prepared the documentation and who is legally responsible for the design.

What if the Architect or Engineer Changes After the Report Is Prepared?

A change in the project team can affect responsibility for the design.

If a new professional takes over the project, provide:

The current plan set
The previously prepared Title 24 report
Updated project information
Revised specifications
Information identifying the current responsible designer

The new project professional should review the applicable work before accepting responsibility for it.

AES can review whether the energy calculations and forms still correspond to the current design.

What if the Plans Change After the Report Is Signed?

A signed report should remain consistent with the design being submitted.

The Title 24 documentation may require revision if the project changes:

Conditioned floor area
Building geometry
Window sizes
Window performance
Insulation
Roof assemblies
HVAC equipment
Duct locations
Ventilation
Water heating
Commercial lighting
Lighting controls

An earlier signature should not be treated as approval of later design changes that were never reviewed.

Send revised plans to AES when an energy-related feature changes.

What if the Building Department Requests a Different Signer?

First determine what the reviewer is actually requesting.

The building department may be identifying:

A missing documentation-author signature
A missing responsible-person signature
An incorrect responsible designer
Missing professional-license information
A document requiring a different responsible professional
A separate installation, acceptance, or verification form

Send AES the complete correction notice and latest project plans.

AES can review whether the energy documentation itself needs correction or whether the requested signature belongs to another member of the design or construction team.

How Do Electronic Signatures and Registered Documents Affect the Process?

Some California energy-compliance documents require electronic registration through an approved Energy Code Compliance process.

When registration is required, applicable signatures are completed electronically according to California Energy Commission requirements.

The project team should not substitute an informal typed name for a required registered electronic signature.

The specific registration requirement depends on the project, document type, and applicable verification measures.

For current state guidance, review the California Energy Commission Building Energy Efficiency Standards.

What Should You Verify Before a Title 24 Report Is Signed?

Before signatures are completed, confirm that the report reflects the project being submitted.

Review:

Project address
Client or project name
Permit scope
Current plan date
Conditioned floor area
Window information
Wall and roof assemblies
Insulation
HVAC systems
Duct locations
Ventilation
Water heating
Commercial lighting and controls

Also confirm:

Who prepared the compliance documentation
Who is responsible for the applicable design
Whether professional-license information is required
Whether document registration is required
Whether separate verification or acceptance forms will be required later

This review helps prevent signature and coordination issues during plan check.

What Documents Should You Send AES?

AES can review the available project information and explain what is needed to prepare or revise the energy documentation.

Helpful documents include:

Current architectural plans
Floor plans
Exterior elevations
Building sections
Roof plans
Window and exterior-door schedules
Insulation details
HVAC specifications
Duct information
Ventilation information
Water-heating specifications
Commercial lighting plans when applicable
Existing Title 24 documentation
Building-department correction notices

Before submitting the project, review what AES will need from you.

Frequently Asked Questions: Who Can Sign Off a Title 24 Report?

Who Can Sign Off a Title 24 Report?

The applicable Certificate of Compliance generally distinguishes between the documentation author who certifies the accuracy and completeness of the documentation and the responsible person who accepts responsibility for the applicable design.

Can the Title 24 consultant sign the report?

A consultant who prepares the energy documentation may sign as the documentation author. The consultant can sign as the responsible person only when legally eligible and actually responsible for the applicable design.

Does an architect always have to sign?

No. The appropriate responsible signer depends on the building, project scope, design responsibility, and California licensing requirements.

Does an engineer always have to sign?

No. An engineer may be the appropriate signer when responsible for the applicable design, but not every project requires the same professional.

Can a builder sign a residential Title 24 form?

For certain residential projects where a licensed design professional is not legally required, an eligible builder or responsible designer may be able to provide the responsible-design signature.

Can a homeowner sign?

Ownership alone does not automatically make someone eligible to provide every responsible-person signature. Eligibility depends on the design responsibility and applicable law.

Who signs an ADU Title 24 report?

The documentation author signs the documentation they prepare, while the person legally responsible for the ADU design provides the applicable responsible-person signature.

Who signs a commercial Title 24 report?

The responsible signer depends on the applicable design scope and may involve an eligible architect, engineer, contractor, or other responsible professional.

What is a documentation author?

The documentation author is the person who prepares the applicable compliance documentation and certifies that the documentation is accurate and complete.

What is the responsible person?

The responsible person is the individual legally eligible to accept responsibility for the applicable building or system design.

Can the same person be the documentation author and responsible person?

Yes, when that person both prepares the documentation and is legally eligible to accept responsibility for the applicable design.

Can an energy consultant prepare the report without designing the building?

Yes. Energy documentation preparation can be delegated while the building designer remains responsible for the design represented by the compliance forms.

Does the building department sign the report?

The building department reviews the submitted documentation. Its plan-review role is separate from the signatures required from the documentation author and responsible person.

Who signs HERS or field-verification documents?

Applicable verification documents are completed and signed by the qualified professional who performs the required field verification or diagnostic testing.

Does a field rater sign as the responsible building designer?

Field verification and building-design responsibility are separate roles. A field-verification professional should not automatically be treated as the responsible building designer.

Who signs installation forms?

The applicable person responsible for construction or installation signs the required installation documentation according to the scope of work.

Can the signer change after the report is prepared?

If project responsibility changes, the current responsible professional should review the applicable work before accepting responsibility for it.

What happens if the building department says the wrong person signed?

Send AES the complete correction notice and current plans so the signature issue can be reviewed in context.

Do electronic Title 24 documents require electronic signatures?

When California’s registration requirements apply, the required signatures must follow the applicable electronic-document and signature procedures.

Does signing the report guarantee permit approval?

No. A properly signed report supports the energy-compliance portion of the permit package, but the building department controls its review and final permit decision.

Do Title 24 Consultants Charge for Corrections?

Posted on October 3, 2026 by Title 24 Energy

Do Title 24 Consultants Charge for Corrections?

Call (626) 365-1518 | Alternative Energy Systems

Receiving a building-department correction often leads to an immediate practical question: Do Title 24 Consultants Charge for Corrections? The answer depends on the original service agreement, what the reviewer requested, whether the project changed after the original report was prepared, and how much additional technical work is required.

A limited clarification is very different from recalculating a project after the floor area, windows, insulation, HVAC equipment, water heating, lighting, or other energy-related features have changed.

Some correction work may fall within the originally arranged service. Other corrections may require additional calculations, revised forms, further plan review, or coordination with newly revised drawings. The project-specific quote or agreement should determine what is included.

Alternative Energy Systems reviews the actual correction notice and current project documents before determining what work is necessary.

AES brings more than 30 years of California energy-compliance experience to residential, multifamily, mixed-use, and commercial permit projects.

Call (626) 365-1518 and send the complete building-department correction notice if you need to determine what must be revised and whether additional work needs to be quoted.

Do Title 24 Consultants Charge for Corrections Every Time?

Not every correction requires the same amount of work, so there should not be one automatic answer for every project.

The first question is whether the correction can be resolved within the work already performed or whether it creates a new scope.

A correction may involve:

A project-information clarification
A missing form
A plan note that needs coordination
An inconsistent window specification
A revised insulation assembly
Different HVAC equipment
A changed water-heating system
A revised commercial lighting design
A different conditioned floor area
A substantial redesign after the original calculations were completed

These situations do not require the same amount of consultant time.

Before assuming that a correction is included or subject to an additional fee, AES should review the complete correction notice and compare it with the original report and current plans.

The Original Scope Determines Where the Correction Review Begins

The original quote or service agreement should be reviewed first.

It may identify:

The report being prepared
The calculations included
The plan set being reviewed
The forms being prepared
Revision terms
Correction-response terms
Turnaround expectations
Additional services outside the original scope

A client should not assume that unlimited future changes are included simply because an initial Title 24 report was purchased.

At the same time, a building-department question does not automatically mean a completely new report is necessary.

The correction must first be evaluated.

A Better Way to Determine Whether a Correction Requires an Additional Fee

Instead of asking only whether corrections are charged, look at what caused the correction and what must now be changed.

The review can generally follow this sequence:

Review the building-department correction notice
Compare the correction with the submitted Title 24 report
Compare the report with the current construction plans
Identify whether the project changed after the original analysis
Determine which calculations, forms, specifications, or plan notes require revision
Determine whether the required work falls within the original project scope
Provide additional pricing when the correction requires work outside that scope

This approach is more accurate than treating every correction as either automatically free or automatically billable.

What Type of Correction May Require Only Limited Revision?

Some corrections may involve a relatively narrow issue.

Examples can include:

Correcting project identification
Clarifying an existing compliance measure
Updating a limited product specification
Coordinating a plan note with the existing calculations
Providing an applicable form that was not included in the submitted package

Whether this work is included depends on the agreed project scope.

The important distinction is that the underlying building design may not have changed.

When the calculations remain applicable, the correction may require less work than a project that must be modeled again.

When Can a Correction Become Additional Work?

Correction work can become more extensive when the report must be revised because the project is no longer the same design that was originally analyzed.

Examples include:

Changing the conditioned floor area
Adding or removing conditioned rooms
Changing the building geometry
Adding or resizing windows
Changing window performance values
Changing wall insulation
Changing roof or ceiling assemblies
Changing HVAC equipment
Changing duct locations
Changing ventilation systems
Changing water-heating equipment
Changing commercial lighting fixtures
Changing lighting controls
Expanding the overall permit scope

Changes like these may affect the technical analysis rather than simply the wording of a form.

When the energy calculations must be revised, additional professional work may be required.

Review the Title 24 energy calculations page for more information about the analysis behind the report.

Was the Correction Caused by a Design Change?

One of the most important questions is whether the plans changed after the original Title 24 report was completed.

Consider this example.

The original report may have been prepared using:

A specific floor area
A defined window schedule
A particular wall and roof assembly
Selected HVAC equipment
A particular water-heating system

The project team may later revise the drawings.

The new plans might show:

A larger addition
More glazing
Different windows
A new HVAC system
Different insulation
A revised water heater

If the original energy forms were submitted without being updated, the building department may identify those differences.

The resulting correction is not simply a request to reprint the original report. The current design may need to be reviewed and recalculated.

Corrections Caused by Inconsistent Plans May Require Coordination

Sometimes the problem is not one isolated Title 24 calculation.

The permit documents may disagree with one another.

For example:

The architectural plan shows one floor area while another sheet shows a different area
The window schedule does not match the exterior elevations
The mechanical schedule lists different equipment from the energy report
The building section shows different insulation from the calculations
The electrical plans show lighting that differs from the analyzed design

AES can review the energy-related conflict, but another project professional may need to revise the drawings.

The Title 24 consultant should not be expected to redesign architectural, mechanical, electrical, structural, or plumbing documents unless those services were separately arranged.

Corrections Involving Windows Can Change the Work Required

Window information can affect the energy analysis significantly enough that revisions should be reviewed carefully.

Compare:

Window identification numbers
Width and height
Quantity
Orientation
U-factor
Solar heat gain coefficient
Glazed exterior doors

A correction involving a simple labeling discrepancy may require less work than a revised window design.

A recalculation may be necessary when:

Several windows were enlarged
New windows were added
Window performance values changed
The orientation represented in the report is no longer accurate

Send the current window schedule when requesting correction review.

Corrections Involving Insulation or Roof Assemblies

The building department may ask for clarification when the insulation shown in the construction plans does not match the report.

Review:

Exterior wall assemblies
Continuous insulation
Roof insulation
Ceiling insulation
Attic conditions
Vaulted ceilings
Raised floors
Floors over garages
Roofing characteristics

If the plans simply need to identify the assembly already used in the calculations, the energy work may be limited.

If the construction assembly itself changed, the calculations may need to be reviewed.

Corrections Involving HVAC Equipment

Mechanical equipment frequently changes during project development.

A building-department correction may identify differences involving:

Heating-system type
Cooling-system type
Equipment efficiency
Heat-pump specifications
Number of systems
Ducted or ductless configuration
Duct locations
Duct insulation
Ventilation equipment

If the system shown in the mechanical plans differs from the system used in the energy calculations, AES should receive the current equipment information.

The extent of the required revision can then be determined.

Corrections Involving Water Heating

A change in water-heating equipment may also affect the report.

Provide current information regarding:

Equipment type
Energy source
Efficiency
Storage configuration
Tankless equipment
Heat-pump water heating
Equipment location
Central or individual systems

If the project team selected a different system after the original report was prepared, the energy documentation should be reviewed before resubmittal.

Commercial Corrections May Require Additional Coordination

Commercial projects may involve several separate energy-related disciplines.

A correction may concern:

Building-envelope information
Mechanical equipment
Ventilation
Service water heating
Interior lighting power
Exterior lighting
Occupancy controls
Automatic shutoff controls
Daylighting controls

Commercial projects can involve architects, mechanical engineers, electrical designers, lighting designers, contractors, property managers, and tenants.

When one discipline changes, the Title 24 documentation may also need review.

For related assistance, review Title 24 compliance services and Title 24 energy analysis.

Does a Building-Department Correction Automatically Require a New Report?

No.

The first step is determining what the reviewer actually requested.

A correction may require:

A clarification
A corrected form
An updated plan note
An updated specification
A limited calculation revision
A more substantial recalculation

The entire report should not be rebuilt unnecessarily when only one limited item needs attention.

Likewise, a significant design change should not be treated as a minor clerical correction when the underlying calculations are no longer based on the current project.

Does a Correction Automatically Mean a New Fee?

Not necessarily.

Whether additional payment is required depends on:

The original service scope
The revision terms of the agreement
The building department’s request
Whether the project changed
How much additional calculation work is required
Whether new forms must be prepared
Whether several design disciplines must be coordinated
Whether the correction is part of a broader redesign

The appropriate approach is to review the correction first and determine the actual amount of work.

AES can then explain whether the requested correction is covered by the existing arrangement or requires an additional quote.

Why Major Design Changes May Affect Correction Pricing

A consultant originally prices the work according to the project presented at the time.

If that project changes substantially, the amount of work can also change.

For example, a report originally prepared for a straightforward addition may later need to address:

A larger conditioned area
Additional rooms
A revised roof
New windows
Different HVAC equipment
Additional mechanical systems

At that point, the consultant may be analyzing a materially different project.

Correction pricing therefore cannot be separated from scope.

What Determines the Cost of Title 24 Correction Work?

The amount of additional work may depend on:

Number of correction comments
Complexity of the requested changes
Completeness of the revised plans
Whether the original calculations remain applicable
Whether the building envelope changed
Whether windows changed
Whether mechanical systems changed
Whether water heating changed
Whether commercial lighting changed
Whether new compliance forms are required
Whether several rounds of revision are needed
Requested turnaround

Pricing should therefore be based on the actual correction package rather than an assumed universal correction fee.

Review Title 24 report pricing in California for related pricing information.

What Should You Send Before Asking About a Correction Fee?

The consultant needs enough information to determine the correction scope.

Send:

The complete building-department correction notice
The latest architectural plans
The Title 24 report previously submitted
Current mechanical plans when applicable
Current electrical and lighting plans when applicable
Updated window and door schedules
Updated insulation information
Updated HVAC specifications
Updated ventilation information
Updated water-heating information
Updated commercial lighting schedules when applicable
A written summary of design changes

Providing the full package allows AES to determine whether the correction is limited or whether significant recalculation is required.

Before sending project files, review what AES will need from you.

Why the Complete Correction Notice Matters Before Pricing

One copied correction comment may not reveal the entire problem.

For example, a reviewer may identify a mechanical discrepancy in one comment and request updated energy documentation in another.

Reviewing only one comment could lead to an incomplete scope estimate.

The complete notice helps identify:

All comments affecting energy compliance
Related corrections in other disciplines
Whether the same design change affects several forms
Whether recalculation is required
Whether the construction plans must also be revised

This can result in a more accurate correction scope and quote.

Who Pays When the Architect or Contractor Changes the Design?

Payment responsibility should be determined among the client and project team according to their own agreements.

The Title 24 consultant may be asked to revise calculations because another project participant changed:

The floor plan
The windows
The insulation
The mechanical equipment
The water-heating system
The lighting design

AES can determine what energy-related work is required, but it does not determine how the owner, architect, contractor, developer, or other project participants divide their costs.

What if the Correction Is Not Actually a Title 24 Problem?

Not every plan-check comment involving energy-related construction requires a revised Title 24 report.

The issue may belong primarily to:

The architect
The mechanical engineer
The electrical designer
The plumbing designer
The contractor
Another consultant

For example, the energy calculations may already show the correct insulation value while the architectural section contains an outdated note.

In that situation, the plan may need correction rather than a complete recalculation.

AES can review the documents and help determine whether the energy report itself is affected.

What if AES Needs to Revise the Report?

When a revision is required, the work may involve:

Reviewing the current plans
Updating project information
Updating the energy model or calculations
Revising compliance measures
Preparing updated forms
Reviewing the forms for consistency
Identifying related plan changes

The extent of this work determines the correction scope.

A limited change should not automatically be treated the same as a major redesign.

Are Residential Correction Fees Different From Commercial Correction Work?

The amount of work depends more on the correction scope than on a simple residential-versus-commercial label.

Residential corrections may involve:

ADUs
Garage conversions
Additions
Major remodels
Windows
Insulation
HVAC equipment
Ventilation
Water heating

Commercial corrections may involve:

Building-envelope calculations
Multiple HVAC systems
Ventilation
Service water heating
Interior lighting
Exterior lighting
Lighting controls
Coordination among several design disciplines

AES reviews each project according to the actual correction work required.

Can ADU Corrections Require Additional Work?

Yes, particularly when the ADU design changes after the original analysis.

Changes may involve:

Conditioned floor area
Attached or detached configuration
Garage-conversion conditions
Window sizes
Insulation
Roof assemblies
HVAC equipment
Ventilation
Water heating

A correction involving only a plan-note clarification may require less work than recalculating a redesigned ADU.

Review the ADU Title 24 page for additional project information.

Can Multiple Correction Cycles Increase the Amount of Work?

Repeated correction cycles can involve additional review when new design changes or new information are introduced between submittals.

For each resubmittal, keep track of:

Which plan version is current
Which report version is current
Which corrections have been addressed
Which specifications changed
Which new comments were issued

Do not mix an older report with a newer drawing set.

Clear version control can help reduce repeated review of the same issue.

How Can You Reduce the Risk of Additional Correction Costs?

The best approach is to reduce preventable revisions before and during plan check.

Send AES the Current Plans

Make sure the energy report is based on the plan set intended for permit submission.

Finalize Major Specifications Early

Provide window, insulation, HVAC, ventilation, water-heating, and lighting information when available.

Notify AES When the Design Changes

Do not wait for the building department to discover that the report and plans are different.

Coordinate the Plans Before Submittal

Compare the energy measures with the architectural and mechanical documentation.

Send the Entire Correction Notice

Do not address one comment while overlooking related issues.

Keep Revisions Organized

Use dates and clear filenames for plans, reports, specifications, and correction responses.

Questions to Ask Before Authorizing Correction Work

Ask:

Is this correction covered by the original scope?
Does the correction require new calculations?
Do the compliance forms need to be revised?
Did the project design change?
Does another project professional need to revise the plans?
What documents are still missing?
Is there an additional correction fee?
What work does that fee cover?
What happens if the building department issues another related comment?
What turnaround should be expected?

These questions help establish the correction scope before additional work begins.

Frequently Asked Questions: Do Title 24 Consultants Charge for Corrections?

Do Title 24 Consultants Charge for Corrections?

Correction charges depend on the original service scope and the amount of additional work required. Review the correction notice, current plans, and original agreement before assuming the work is included or separately billed.

Are all building-department corrections charged separately?

Not necessarily. The correction should be reviewed first to determine what work is required and whether it falls within the original scope.

Are corrections always included in the original Title 24 fee?

Do not assume unlimited correction work is included. The project-specific quote or agreement should determine the included scope.

Does every correction require new calculations?

No. Some comments may require clarification, updated forms, or coordinated plan notes rather than recalculation.

When might recalculation be required?

Recalculation may be needed when floor area, windows, insulation, roof assemblies, HVAC systems, ventilation, water heating, commercial lighting, or other analyzed features change.

Can changing the plans lead to additional correction work?

Yes. When the current plans differ from the design used for the original report, the calculations and forms may need revision.

Can window changes increase the correction scope?

They can. Changes to window sizes, quantities, orientations, U-factors, or solar heat gain coefficients may affect the analysis.

Can HVAC changes require additional correction work?

Yes. Changes to equipment type, efficiency, ducts, or ventilation may require the energy documentation to be reviewed or recalculated.

Can commercial lighting corrections require updated calculations?

Yes. Revised fixtures, wattage, quantities, room uses, or lighting controls may affect commercial compliance documentation.

What should I send before requesting a correction quote?

Send the complete correction notice, latest plans, previous Title 24 report, relevant revised plans, current specifications, and a summary of project changes.

Why does AES need the complete correction notice?

Related comments may reveal whether the issue affects the report, another design discipline, or several documents at the same time.

Can AES tell whether the correction is actually a Title 24 issue?

AES can review the comment and determine whether the energy calculations or forms are affected or whether the primary revision belongs to another project professional.

Can a correction require new forms without a complete new report?

Yes. The required response depends on what changed. Some projects may need only specific documentation updated.

Do repeated correction cycles require additional work?

They can when new comments, design changes, or revised specifications require further analysis.

Who pays when another project professional changes the design?

The client and project team should determine payment responsibility according to their own agreements. AES can identify the energy-compliance work that needs to be performed.

Does correcting the report guarantee building-department approval?

No. The building department controls its review and may request additional clarification.

How can I reduce future correction costs?

Use current plans, provide complete specifications, coordinate energy measures before submittal, disclose design changes promptly, and keep revisions organized.

What if the Building Department Requests Corrections to a Title 24 Report

Posted on October 3, 2026 by Title 24 Energy

What if the Building Department Requests Corrections to a Title 24 Report?

Call (626) 365-1518 | Alternative Energy Systems

Receiving a plan-check correction does not automatically mean your entire energy report is wrong or that the permit process has failed. What if the Building Department Requests Corrections to a Title 24 Report is usually a question of identifying exactly what the reviewer wants clarified, comparing that request with the current plans, and updating the affected calculations, forms, specifications, or plan notes.

A correction may be relatively limited, such as an inconsistent project detail or missing form. It may also reveal that the construction plans changed after the energy calculations were completed, requiring portions of the report to be recalculated.

The most important first step is to send the complete correction notice along with the latest project documents rather than trying to interpret one comment in isolation.

Alternative Energy Systems can review the building-department comments, compare them with the Title 24 report and current plans, identify which energy-related items require attention, and help prepare revised documentation for resubmittal.

AES brings more than 30 years of California energy-compliance experience to residential, multifamily, mixed-use, and commercial permit projects.

Call (626) 365-1518 if your project has received Title 24 or energy-related plan-check corrections.

What Should You Do First After Receiving a Title 24 Correction?

Do not immediately change the report based on one sentence from the reviewer.

Start by collecting the complete project record.

Provide AES with:

The complete building-department correction notice
The latest architectural plan set
The Title 24 report that was submitted
Any revised mechanical plans
Any revised electrical or lighting plans
Updated window and exterior-door information
Updated HVAC specifications
Updated water-heating specifications
Updated commercial lighting information when applicable
A written description of changes made since the original report

This allows the correction to be evaluated in context.

A comment that appears to concern one form may actually originate from a discrepancy elsewhere in the plans. Likewise, a mechanical correction may require changes to both the equipment schedule and the energy calculations.

A Building-Department Correction Does Not Necessarily Mean the Entire Report Failed

Plan reviewers may issue corrections for many reasons.

Some corrections involve the Title 24 report itself. Others involve differences between the report and another part of the construction documents.

For example:

The energy calculations may show one window size while the elevation shows another
The report may list one HVAC efficiency while the mechanical schedule lists another
The plans may show a different insulation assembly from the calculations
The project floor area may have changed after the original report
A required compliance form may be missing from the permit package
A commercial lighting schedule may no longer match the energy documentation

The correction must be diagnosed before the proper response can be prepared.

That is why the full correction notice and current plans are important.

The Best Correction Process: Review, Diagnose, Revise, Coordinate, Resubmit

A strong correction response generally follows five stages.

1. Review the Complete Correction Notice

Read all building-department comments, including comments that appear outside the energy section.

A correction in another discipline may affect information used in the Title 24 calculations.

2. Diagnose the Source of the Conflict

Compare the correction with:

The submitted Title 24 report
The current architectural drawings
The mechanical plans
The electrical and lighting plans
Product schedules
Equipment specifications

Determine whether the problem is a missing document, inconsistent value, revised design, calculation issue, or plan-note issue.

3. Revise the Affected Documentation

Depending on the correction, AES may need to update:

Energy calculations
Compliance forms
Project information
Window specifications
Envelope assumptions
Mechanical-system information
Commercial lighting information

The architect, designer, mechanical engineer, electrical designer, or contractor may also need to revise the corresponding construction plans.

4. Coordinate the Revised Report With the Plans

The correction response should not create a new conflict.

The revised report and revised plan set should describe the same project.

5. Resubmit the Corrected Package

The corrected documents can then be incorporated into the project’s plan-check resubmittal according to the building department’s procedures.

What Types of Title 24 Corrections Do Building Departments Request?

Energy-related corrections may involve:

Missing compliance forms
Incorrect project information
Incorrect conditioned floor area
Window discrepancies
Missing window performance values
Insulation conflicts
Roof-assembly conflicts
HVAC equipment discrepancies
Duct-location questions
Ventilation information
Water-heating information
Commercial lighting power
Lighting-control requirements
Differences between calculations and construction plans
Outdated energy documentation

The response depends on the actual comment.

A missing form may be resolved differently from a correction requiring the building envelope to be recalculated.

Why Should You Send the Complete Correction Notice?

Sending only the sentence that mentions Title 24 can leave out important context.

Plan-check comments are often connected.

For example, one comment may request:

A revised mechanical schedule
An updated energy form
A corresponding plan note

Looking only at the energy comment could result in updating the report while leaving the underlying mechanical discrepancy unresolved.

The complete correction notice helps AES determine:

Which comments relate directly to energy compliance
Which comments belong to another design professional
Which comments affect several disciplines
Whether the calculations need revision
Whether only the plans need clarification
Whether both the plans and energy forms need updating

Addressing the complete issue is generally more efficient than responding to isolated comments one at a time.

Compare the Correction Notice With the Latest Plan Set

Before revising the energy report, confirm which plans the building department reviewed.

The current plan set may differ from the drawings originally provided to AES.

Compare:

Plan dates
Revision dates
Floor areas
Room layouts
Window schedules
Insulation details
Roof assemblies
Mechanical schedules
Water-heating information
Commercial lighting schedules

If AES prepared the calculations from an earlier version of the plans, the correction may require more than a simple form edit.

The energy analysis may need to be updated to reflect the revised design.

Common Correction: The Title 24 Report Does Not Match the Plans

One of the most important coordination issues is consistency between the report and construction drawings.

The documents should agree regarding:

Project address
Conditioned floor area
Building orientation
Windows and doors
Wall construction
Roof and ceiling assemblies
Insulation values
HVAC equipment
Duct locations
Ventilation
Water heating
Commercial lighting
Lighting controls

A report can contain technically valid calculations and still generate corrections when it does not match the plan set submitted to the building department.

The report and plans serve different purposes, but they must communicate the same project requirements.

Common Correction: Window Information Does Not Match

Window information may appear on:

Floor plans
Exterior elevations
Window schedules
Product specifications
Energy calculations
Compliance forms

These documents should remain consistent.

Review:

Window identification numbers
Width and height
Quantity
Orientation
U-factor
Solar heat gain coefficient
Glazed exterior doors

A correction may result when a window is resized, removed, added, or replaced with a different performance specification after the original report is completed.

If the window design changed, AES may need to update the calculations rather than simply edit a note.

Common Correction: Insulation or Roof Information Is Inconsistent

The building-envelope information in the plans should reflect the assemblies used in the energy analysis.

Review:

Exterior wall insulation
Continuous insulation
Roof insulation
Ceiling insulation
Attic configuration
Vaulted ceiling assemblies
Floor insulation
Floors over garages
Walls adjoining unconditioned areas
Roofing characteristics

A general note such as “insulate per code” may not communicate the project-specific assembly represented in the calculations.

The building sections and details should show the relevant insulation information.

Common Correction: HVAC Information Has Changed

Mechanical equipment is frequently selected or revised while permit plans are being developed.

The building department may identify a difference between the energy report and mechanical schedule involving:

System type
Heating efficiency
Cooling efficiency
Heat-pump information
Number of systems
Equipment location
Ducted or ductless configuration
Duct location
Duct insulation
Ventilation equipment

When the proposed equipment changes, provide AES with the current mechanical specifications.

The energy calculations and forms can then be reviewed against the actual equipment proposed for installation.

Common Correction: Water-Heating Information Does Not Match

Water-heating changes may also affect the energy documentation.

Review:

Equipment type
Fuel or energy source
Efficiency
Storage or tankless configuration
Heat-pump water heating
Equipment location
Individual or central service

The report should not show one water-heating system while the plumbing or mechanical plans show another.

Commercial Title 24 Corrections May Involve Lighting and Controls

Commercial permit projects may receive corrections involving:

Interior lighting power
Fixture wattage
Fixture quantities
Room or space classifications
Occupancy sensors
Automatic shutoff controls
Daylighting controls
Exterior lighting
Mechanical systems
Ventilation
Service water heating
Building-envelope information

Commercial projects often involve several design professionals.

A lighting correction may require coordination among:

The Title 24 consultant
The architect
The electrical designer
The lighting designer
The contractor
The property owner or tenant

Updated fixture schedules and lighting-control plans should be provided when the electrical design changes.

For related commercial services, review Title 24 compliance services and Title 24 energy analysis.

Does Every Correction Require New Energy Calculations?

No.

Some correction comments may require only limited clarification or documentation changes.

Others may require the project to be recalculated.

A recalculation may be necessary when the correction involves changes to:

Conditioned floor area
Building geometry
Window sizes
Window performance
Insulation values
Roof assemblies
HVAC equipment
Duct conditions
Ventilation systems
Water heating
Commercial lighting power
Lighting controls

The correction notice and revised plans must be reviewed before determining whether new calculations are required.

Does Every Correction Require New Title 24 Forms?

Not necessarily.

The forms may need revision when project information or calculation results change.

Examples include:

A different conditioned floor area
Revised windows
Different insulation
New mechanical equipment
Changed water heating
Revised commercial lighting

A correction involving only a plan note may not require every energy form to be regenerated.

AES can review the scope and determine which documentation needs attention.

Who Is Responsible for Correcting the Construction Plans?

The Title 24 consultant prepares and revises the energy-compliance documentation within the agreed scope.

The construction plans may be prepared or controlled by:

An architect
A building designer
A mechanical engineer
An electrical designer
A plumbing designer
A contractor
Another project professional

When the correction requires a change to the drawings, the person responsible for those drawings should update them.

AES can identify energy measures that should remain coordinated with the plans, but revising the Title 24 report does not automatically revise architectural, structural, mechanical, electrical, or plumbing drawings prepared by others.

What Documents Should You Send AES for a Correction Review?

For the most efficient review, send the correction package together rather than in separate messages whenever possible.

Include:

Complete building-department correction notice
Latest architectural plans
Previously submitted Title 24 report
Revised mechanical plans when applicable
Revised electrical plans when applicable
Current window and door schedule
Current insulation details
Current HVAC specifications
Current ventilation information
Current water-heating information
Current commercial lighting schedule when applicable
A summary of changes made after the previous submission

Clearly identify which plan set is current.

Before sending project documents, review what AES will need from you.

How Should You Organize the Correction Package?

A well-organized submission can reduce unnecessary back-and-forth.

Use descriptive filenames such as:

Project-Address-Correction-Notice.pdf
Project-Address-Revised-Plans-Date.pdf
Project-Address-Existing-Title-24-Report.pdf
Project-Address-HVAC-Specifications.pdf
Project-Address-Window-Schedule.pdf

Include a short written summary explaining:

Which comments appear to involve Title 24
Which plans changed
Which products changed
Which design professionals have already responded
Whether the building department provided a resubmittal deadline

Avoid sending multiple unlabeled files named “final,” “new final,” or “revision” without dates or explanations.

What Happens After AES Reviews the Corrections?

After reviewing the correction notice and supporting documents, AES can determine the appropriate energy-compliance response.

The next step may involve:

Clarifying an existing form
Correcting project information
Updating a product specification
Revising calculations
Preparing updated compliance forms
Identifying a required plan-note change
Coordinating with the architect or contractor

The scope depends on the reviewer’s comments and the current design.

How Do You Prepare the Corrected Package for Resubmittal?

Before resubmitting, compare the revised documents one more time.

Verify that:

The project address is correct
The latest plan set is being used
The conditioned floor area matches
The windows match
The insulation assemblies match
The HVAC information matches
The ventilation information matches
The water-heating information matches
The commercial lighting information matches
The applicable revised forms are included
The specific plan-check comments have been addressed

The corrected report and corrected drawings should be submitted together when the correction affected both.

Should You Respond to Each Building-Department Comment?

A correction response is easier to review when each applicable comment is addressed clearly.

The project team may prepare a response identifying:

The correction number
What was requested
What was changed
Which plan sheet changed
Which Title 24 form changed

The exact resubmittal format depends on the building department.

Follow the jurisdiction’s instructions for response letters, revised sheets, clouded changes, or uploaded replacement files.

How Long Do Title 24 Corrections Take?

Correction timing depends on the scope.

A limited clarification may require less work than a correction involving:

A redesigned building envelope
Changed conditioned floor area
Numerous revised windows
Different HVAC systems
Changed commercial lighting
Multiple connected correction comments

Timing may also depend on how quickly the project team provides missing information.

A correction cannot be finalized accurately when AES is still waiting for the revised plans or equipment specifications.

Call (626) 365-1518 to discuss the correction scope and requested schedule.

Do Title 24 Corrections Cost Extra?

Correction pricing depends on the original service agreement and the amount of additional work required.

A limited clarification may differ from a substantial recalculation caused by major design changes.

Additional work may be required when:

The plans changed significantly after the original report
Conditioned floor area changed
Windows were redesigned
Mechanical systems changed
Commercial lighting changed
The permit scope expanded
Multiple correction cycles require new revisions

AES can review the correction package and determine whether the requested work falls within the existing scope or requires a separate quote.

What if the Correction Involves HERS Verification?

Some residential projects may include measures requiring separate field testing or verification.

The Title 24 report can identify applicable verification measures, but the report itself does not replace:

Field testing
Diagnostic testing
Construction inspections
Installation verification
Documentation completed by the appropriate field professional

If a building-department correction refers to verification requirements, the project team should determine whether the comment concerns:

The energy report
The plans
A missing verification measure
Separate field documentation

For additional background, review Title 24 vs. CALGreen.

What if the Correction Is Not Actually a Title 24 Issue?

Not every comment mentioning energy-related construction requires AES to revise the report.

The correction may belong primarily to:

The architect
The mechanical engineer
The electrical designer
The plumbing designer
The contractor
Another project consultant

AES can review the comment and determine whether the Title 24 documentation is affected.

This helps prevent unnecessary changes to a report when the actual correction belongs elsewhere in the permit package.

Can the Building Department Issue Another Correction After Resubmittal?

Yes. A corrected submission does not guarantee that no additional comments will be issued.

The building department may:

Confirm that the original comment was addressed
Request additional clarification
Identify another inconsistency
Review revised information that creates a new question

The goal is to provide a complete and coordinated response that reduces preventable repeat comments.

No Title 24 consultant can guarantee the building department’s final review decision.

How Can You Reduce Future Title 24 Corrections?

Many avoidable corrections begin with coordination problems.

Provide the Current Plans Before Calculations Begin

Make sure AES receives the latest plan set.

Finalize Important Specifications Early

Provide window, insulation, HVAC, water-heating, and lighting information before the report is finalized when possible.

Report Design Changes Immediately

Do not wait until plan check to mention significant revisions.

Compare the Report With the Permit Plans

Check the major energy measures before submitting the permit package.

Use Consistent Product Information

Do not show different performance values on separate plan sheets.

Keep Revision Dates Clear

Identify which plan set and report version are current.

Submit Complete Correction Packages

When corrections occur, provide the full notice, plans, report, and updated specifications together.

Frequently Asked Questions: What if the Building Department Requests Corrections to a Title 24 Report?

What if the Building Department Requests Corrections to a Title 24 Report?

Send AES the complete correction notice, latest plans, previously submitted report, updated specifications, and a summary of any design changes. AES can determine which calculations, forms, specifications, or plan notes may need revision.

Does a correction mean the entire Title 24 report is wrong?

No. A correction may involve a limited documentation issue, a conflict between the report and plans, missing information, or a design change.

Should I send only the Title 24 correction comment?

Send the complete correction notice whenever possible. Related comments may provide important context.

What plans should I send?

Send the latest architectural plans and any current mechanical, electrical, lighting, or other plans related to the correction.

Should I send the old Title 24 report?

Yes. AES needs the previously submitted report to compare it with the correction notice and current plans.

Does every correction require recalculation?

No. Some comments may require clarification or updated forms, while others require revised calculations.

When are new calculations usually needed?

Recalculation may be needed when floor area, geometry, windows, insulation, HVAC systems, water heating, commercial lighting, or other energy-related project features change.

Can window changes cause a Title 24 correction?

Yes. Differences in window size, quantity, orientation, U-factor, solar heat gain coefficient, or location may require review.

Can HVAC changes cause a correction?

Yes. The report and mechanical plans should remain consistent regarding system type, efficiency, equipment, ducts, and ventilation.

Can commercial lighting changes require revised Title 24 forms?

They can. Changes to fixtures, wattage, quantities, room uses, or lighting controls may affect the analysis.

Who updates the architectural plans?

The professional or project team responsible for the construction drawings should make the applicable plan changes. AES handles the energy-compliance documentation within its service scope.

Can AES help determine whether the correction belongs to another consultant?

AES can review the comment and determine whether the Title 24 documentation is affected or whether the primary correction belongs to another design discipline.

How long do corrections take?

Timing depends on the complexity of the comments, extent of project changes, completeness of the submitted information, and whether recalculation is required.

Do corrections cost extra?

That depends on the original agreement and the amount of additional work. Significant redesign or additional calculation work may require a separate quote.

Can a corrected Title 24 report be resubmitted?

Yes. Revised energy documentation can be coordinated with corrected plans and incorporated into the permit resubmittal.

Can the building department issue another correction?

Yes. The jurisdiction controls its review and may request additional clarification after resubmittal.

Does correcting the Title 24 report guarantee permit approval?

No. The energy report supports one part of the permit application. The complete project remains subject to building-department review.

What is the best way to prevent repeat corrections?

Use current plans, keep specifications coordinated, disclose design changes promptly, and make sure revised energy forms and revised drawings describe the same project.

How do I request help with my correction notice?

Call Alternative Energy Systems at (626) 365-1518 and send the complete correction notice and latest project documents for review.

Will a Title 24 Report Be Accepted by the Building Department?

Posted on August 4, 2026 by Title 24 Energy

Will a Title 24 Report Be Accepted by the Building Department?

Call (626) 365-1518 | Alternative Energy Systems

Building-department acceptance depends on whether the energy documentation is complete, accurate, appropriate for the project, and coordinated with the permit drawings. Will a Title 24 Report Be Accepted by the Building Department cannot be answered with an unconditional guarantee because the jurisdiction controls its own review and may request clarification or corrections.

A professionally prepared Title 24 report can support the energy-compliance portion of a California permit application. The report should be based on the current plans and should accurately document the proposed building envelope, windows, HVAC equipment, duct locations, ventilation, water heating, lighting, controls, and other applicable energy measures.

Acceptance can become more difficult when the report:

Uses outdated plans
Lists a different project address
Does not match the proposed floor area
Contains window information that conflicts with the drawings
Uses different insulation values from the plan details
Lists HVAC equipment that is no longer proposed
Omits required project information or forms
Does not reflect recent design revisions

Alternative Energy Systems brings more than 30 years of California energy-compliance experience to residential, multifamily, mixed-use, and commercial permit projects. AES reviews the project documents, identifies missing information, completes the applicable analysis, and helps coordinate the resulting forms with the current design.

Call (626) 365-1518 to submit your plans, request a Title 24 report, or receive help with energy-related plan-check corrections.

Will a Title 24 Report Be Accepted by the Building Department Automatically?

No Title 24 report should be treated as automatically accepted before the building department reviews it.

The jurisdiction may evaluate whether:

The correct forms were submitted
The documentation applies to the correct property
The project type and scope are identified accurately
The calculations use the current building design
The report matches the architectural plans
The mechanical information is consistent
The lighting information is complete when applicable
The required energy measures appear on the plans
Additional clarification or verification is needed

A report may be professionally prepared and still receive a correction when the plans change after the calculations are completed or when another part of the permit package shows inconsistent information.

The purpose of professional preparation is to reduce preventable discrepancies and provide the building department with a clear, project-specific compliance package. It does not remove the jurisdiction’s authority to review the documents.

What Does Building-Department Acceptance Mean?

Acceptance generally means that the jurisdiction has reviewed the submitted energy documentation and determined that it can proceed as part of the permit package.

That does not necessarily mean:

The entire permit has been approved
No corrections will be issued by another department
Every construction product has been approved
The building has passed inspection
All field-verification requirements have been completed
The project can be changed without revising the report

The complete permit application may also require review of:

Zoning
Architectural plans
Structural engineering
Fire and life-safety requirements
Accessibility
Mechanical plans
Electrical plans
Plumbing plans
CALGreen documentation
Other jurisdiction-specific requirements

The Title 24 report supports the energy-compliance portion of this larger process.

What Makes a Title 24 Report More Likely to Be Accepted?

A strong submission is based on complete project information and coordinated construction documents.

The report should:

Identify the correct project address
Use the current plan set
Reflect the correct conditioned floor area
Identify the applicable project scope
Include the appropriate energy calculations
Include the applicable compliance forms
Match the window and door schedules
Match the insulation and roof details
Match the proposed HVAC equipment
Match the duct and ventilation design
Match the water-heating specifications
Match commercial lighting and controls when applicable

The construction drawings should also show the energy measures used in the analysis.

A report cannot compensate for a permit set that contains conflicting information. Likewise, well-developed plans may remain incomplete when the applicable energy forms have not been prepared.

The Report Must Match the Current Plans

Plan coordination is one of the most important factors affecting acceptance.

The report and drawings should agree regarding:

Project address
Occupancy or building type
Conditioned floor area
Number of units or conditioned spaces
Building orientation
Window sizes and locations
Window performance values
Exterior-door information
Wall, roof, ceiling, and floor insulation
HVAC equipment
Duct locations
Ventilation systems
Water-heating equipment
Commercial lighting fixtures
Lighting controls

A correct energy calculation based on an outdated floor plan may still lead to corrections.

For example, the report may show one window configuration while the elevations show a later design. The mechanical schedule may list one HVAC model while the report uses another. The architectural sections may show a different insulation assembly from the one used in the analysis.

These differences should be corrected before permit submittal whenever possible.

Use the Correct Project Address and Identification

Basic identification errors can create unnecessary questions during plan review.

Verify:

Street address
Unit or suite number
Client or project name
Residential or commercial designation
New construction, addition, alteration, or conversion scope
Plan date or revision date

Do not submit a report copied from another property or based on a similar project.

Title 24 calculations are project-specific. A report prepared for another building should not be assumed to apply merely because the square footage or project type appears similar.

Submit the Applicable Forms

The forms required for a project depend on the occupancy, construction scope, building systems, and selected compliance approach.

A new home may not use the same documentation as:

A detached ADU
A garage conversion
A residential addition
An HVAC replacement
A commercial tenant improvement
A lighting alteration
A new nonresidential building

AES reviews the project scope to determine what analysis and documentation may apply.

Submitting incomplete or unrelated forms can result in corrections even when parts of the energy analysis are otherwise accurate.

Window Information Must Be Consistent

Window discrepancies are a common source of coordination problems.

The report, plans, elevations, and window schedule should agree regarding:

Window identification numbers
Width and height
Quantity
Location
Orientation
U-factor
Solar heat gain coefficient
Glazed exterior doors

Before submitting the permit package, check for:

Windows appearing on elevations but not on the schedule
Different sizes shown on separate sheets
Missing performance values
Products changed after the report was prepared
New windows added during design revisions

A revised window design may require updated calculations and forms.

Insulation and Roof Details Must Match

The report should reflect the actual proposed building-envelope assemblies.

Review the plans and report for consistency involving:

Exterior wall insulation
Continuous insulation
Roof insulation
Ceiling insulation
Attic configuration
Vaulted ceiling assemblies
Raised-floor insulation
Floors over garages or unconditioned spaces
Roofing characteristics

A general plan note stating “insulate per code” may not communicate the project-specific assembly used in the calculations.

The construction sections and details should identify the insulation values and locations represented in the report.

Mechanical Information Must Be Coordinated

The report may evaluate heating, cooling, ducts, ventilation, and other mechanical features.

The documentation should agree regarding:

System type
Number of systems
Heating efficiency
Cooling efficiency
Heat-pump information
Equipment location
Ducted or ductless configuration
Duct location
Duct insulation
Ventilation equipment
Areas served by each system

Mechanical equipment is sometimes selected or changed after the initial energy analysis. When that happens, send the updated specifications to AES before submitting the old report with the new mechanical schedule.

Water-Heating Information Must Be Current

Water-heating details can also affect the report.

Verify:

Equipment type
Fuel or energy source
Efficiency
Storage, tankless, or heat-pump configuration
Equipment location
Individual or central service
Distribution information when applicable

A change from one water-heating system to another may require the documentation to be reviewed or revised.

Commercial Lighting and Controls Must Match the Electrical Plans

Commercial and nonresidential projects may require detailed lighting information.

The building department may review:

Lighting floor plans
Fixture schedules
Fixture identification numbers
Fixture wattage
Fixture quantities
Room or space use
Occupancy sensors
Automatic shutoff controls
Daylighting controls
Exterior lighting
Control notes and diagrams

The report, fixture schedule, and electrical plans should describe the same lighting design.

Missing wattage, undefined controls, or fixtures changed after the analysis can lead to correction comments.

For related commercial services, review Title 24 compliance services and Title 24 energy analysis.

Will a Residential Title 24 Report Be Accepted?

A residential report can support permit review when it accurately represents the proposed project and includes the applicable documentation.

Residential projects may include:

New single-family homes
New multifamily buildings
Detached ADUs
Attached ADUs
Garage conversions
Room additions
Second-story additions
Major remodels
Window or envelope alterations
HVAC-related permit projects

Residential calculations may evaluate:

Conditioned floor area
Building orientation
Wall, roof, ceiling, and floor assemblies
Window area and performance
Heating and cooling equipment
Duct locations
Mechanical ventilation
Domestic water heating
Applicable residential lighting measures

The report should be prepared from the residential plans being submitted to the jurisdiction.

Will an ADU Title 24 Report Be Accepted?

An ADU report should be based on the exact accessory dwelling unit shown in the permit drawings.

AES may need:

ADU floor plan
Exterior elevations
Building sections
Roof plan
Window and exterior-door schedule
Insulation details
HVAC specifications
Ventilation information
Water-heating details

For an attached ADU or garage conversion, the plans should distinguish:

Existing conditioned space
Existing unconditioned space
New conditioned living area
New or altered walls
Existing systems that remain
New or replaced equipment

An ADU report prepared from preliminary plans may require revision if the windows, floor area, roof, insulation, HVAC system, or water-heating design changes.

Visit the ADU Title 24 page for additional information.

Will an Addition or Remodel Report Be Accepted?

An addition or remodel report should identify the energy-related portions of the proposed work clearly.

The plan set may need to show:

Existing floor area
New conditioned floor area
Removed and proposed walls
New windows and doors
New insulation
Roof and ceiling changes
Existing or proposed HVAC systems
Duct extensions
Ventilation changes
Water-heating changes

Corrections may result when the report evaluates one scope while the plans show additional work.

Describe the complete project before the calculations begin.

Will a Commercial Title 24 Report Be Accepted?

Commercial acceptance depends on whether the report and supporting plans address the applicable nonresidential scope accurately.

Commercial projects may include:

New nonresidential buildings
Office tenant improvements
Retail build-outs
Restaurant improvements
Warehouse alterations
Mixed-use projects
Commercial HVAC replacements
Interior lighting alterations
Exterior lighting projects
Multifamily common-area improvements

Commercial documentation may involve:

Building-envelope calculations
Mechanical systems
Ventilation
Service water heating
Interior lighting power
Exterior lighting
Lighting controls

Commercial projects often require coordination among architects, mechanical engineers, electrical designers, contractors, owners, and property managers.

Conflicting information among the separate design disciplines can result in plan-check comments.

Why Might the Building Department Reject or Correct a Report?

A building department may request corrections when:

The required forms are missing
The project address is incorrect
The report applies to an older plan version
The floor area does not match the plans
The window schedule conflicts with the calculations
Insulation details are missing or inconsistent
Mechanical equipment differs between documents
Ventilation information is incomplete
Water-heating specifications do not match
Commercial lighting power is incomplete
Lighting controls are not documented
The project scope changed after the report was prepared
Additional clarification is requested

A correction does not always mean the entire energy analysis is unusable.

The issue may require:

A corrected project reference
An updated product specification
A revised plan note
An updated compliance form
A recalculation based on changed plans
Coordination among the design documents

AES can review the complete correction notice and determine what energy-related response is needed.

What Should You Send After Receiving Corrections?

Send AES:

The complete building-department correction notice
The latest architectural plan set
Current mechanical plans
Current electrical and lighting plans
The previously submitted Title 24 report
Updated product and equipment specifications
A written summary of changes already made

Do not send only one sentence copied from the correction notice when the complete document is available.

The surrounding comments can provide important context and help determine whether the issue affects the forms, calculations, plan notes, or another design discipline.

What Happens if the Plans Change After the Report Is Prepared?

The report may need to be revised whenever a design change affects information used in the analysis.

Changes may include:

Conditioned floor area
Building geometry
Window sizes
Window performance values
Exterior doors
Insulation values
Roof or ceiling assemblies
HVAC equipment
Duct locations
Ventilation systems
Water-heating equipment
Commercial lighting fixtures
Lighting controls
The overall permit scope

Submit the latest plans and a written change summary so AES can identify which calculations and forms require revision.

Do not submit an old report with substantially revised drawings and assume the building department will accept the combination.

Can a Previously Accepted Report Be Reused?

A previously accepted report may provide useful background, but it should not be reused automatically.

AES may need:

The previous report
The plans used to prepare that report
The current plan set
Updated window information
Updated insulation details
Current HVAC specifications
Current water-heating information
Updated commercial lighting documents
A written summary of project changes

Prior acceptance applied to the project information reviewed at that time. It does not automatically establish acceptance of a different design, revised scope, or new permit application.

Does HERS Verification Affect Acceptance?

Some residential projects may include measures requiring field testing or verification.

The Title 24 consultant prepares the energy analysis and applicable forms. Field testing and verification are completed separately by the appropriate professional.

The report may identify measures involving:

Duct systems
Airflow
Mechanical equipment
Other performance-sensitive features

A report is not a substitute for required field testing, construction inspection, or installation verification.

The project team should understand:

Which measures require verification
Who is responsible for arranging it
When it must occur
What documentation must be completed

For related information, review Title 24 vs. CALGreen.

Does AES Guarantee Building-Department Acceptance?

No professional should promise unconditional approval of a complete permit application.

The building department controls:

Its review procedures
Its interpretation of the submitted documents
Its correction comments
Its processing schedule
Its final permit decision

AES can prepare project-specific energy documentation, identify missing information, coordinate the report with the plans, and assist with energy-related corrections.

AES cannot control:

Other design disciplines
Unreported project changes
Incomplete information supplied by the project team
Building-department processing times
Corrections unrelated to the energy documentation
Construction that differs from the approved plans

The goal is to provide accurate, coordinated energy documentation that gives the project a stronger basis for plan review.

How Can You Improve the Chance of Acceptance?

Before submitting the report:

Use the Current Plans

Confirm that AES received the same plan set being submitted to the building department.

Review the Project Address

Make sure the address, unit, suite, and project name are correct.

Compare the Windows

Confirm that sizes, quantities, locations, and performance values match.

Compare Insulation and Roof Details

Verify that the plan sections show the assemblies used in the calculations.

Compare Mechanical Equipment

Confirm that the report and mechanical schedule list the same systems.

Review Ventilation and Water Heating

Check that the current equipment and configurations are documented.

Review Commercial Lighting

Confirm that fixture wattage, quantities, room uses, and controls match the electrical plans.

Include the Applicable Forms

Make sure the complete energy-compliance package is included with the permit set.

Report Design Changes Promptly

Notify AES before submitting revised plans with an outdated report.

Respond to Corrections Completely

Send the full correction notice and latest plans rather than addressing comments in isolation.

When Should You Request the Report?

Request the report after the project has enough detail to identify the building envelope and major systems, but before the permit package is treated as final.

Early review can help identify unresolved information involving:

Windows
Insulation
Roof construction
HVAC equipment
Duct locations
Ventilation
Water heating
Commercial lighting
Lighting controls

Waiting until the intended permit-submittal date leaves less time to resolve conflicts and update the drawings.

Before sending files, review what AES will need from you.

Frequently Asked Questions: Will a Title 24 Report Be Accepted by the Building Department?

Will a Title 24 Report Be Accepted by the Building Department?

A properly prepared and coordinated report can support building-department review, but acceptance cannot be guaranteed. The jurisdiction controls its review and may request clarification or corrections.

Is every professionally prepared report automatically accepted?

No. The report must apply to the correct project, include the applicable forms, and match the current permit plans.

Does acceptance mean the entire permit is approved?

No. The building department may still review zoning, architecture, structural engineering, fire safety, accessibility, mechanical, electrical, plumbing, CALGreen, and other requirements.

What is the most important factor affecting acceptance?

The report, calculations, forms, specifications, and construction drawings should describe the same project.

Can the report be accepted if the plans changed?

The report may need revision when the plans change. Submit the updated drawings and a written change summary for review.

Can I use a report prepared for another property?

No. Title 24 documentation should be based on the actual property and proposed design.

Can I reuse an old report?

An old report should be compared with the current plans. Changes to floor area, windows, insulation, HVAC, water heating, lighting, or project scope may require revision.

What window information must match?

Window sizes, quantities, locations, orientations, U-factors, solar heat gain coefficients, and glazed-door information should be coordinated.

What mechanical information must match?

The report and plans should identify the same system types, efficiencies, equipment locations, duct conditions, and ventilation systems.

What commercial lighting information is reviewed?

The jurisdiction may review fixture wattage, quantities, space uses, occupancy sensors, automatic controls, daylighting controls, and exterior lighting information.

Why might the building department issue corrections?

Corrections may result from missing forms, outdated plans, inconsistent specifications, incomplete notes, mechanical conflicts, lighting-control issues, or differences between the report and drawings.

What should I send AES after receiving corrections?

Send the complete correction notice, latest plans, previous report, updated specifications, and a written summary of changes already made.

Does AES guarantee acceptance?

No. AES can prepare and coordinate the energy documentation, but the building department controls its review and final decisions.

Does a report guarantee permit approval?

No. The report supports the energy-compliance portion of the application. The complete permit package remains subject to jurisdictional review.

Does the report include building-department submission?

Do not assume that AES submits the complete permit package unless that service has been arranged. The architect, designer, contractor, owner, or permit coordinator may manage submission.

Does the report include HERS testing?

The report may identify verification measures, but field testing and inspections are separate activities performed by the appropriate professional.

Can AES revise a rejected or corrected report?

AES can review the complete correction notice and current plans to determine whether calculations, forms, specifications, or plan notes require revision.

How can I reduce the chance of corrections?

Submit one current plan set, provide complete specifications, coordinate all energy measures, and report design changes before permit submittal.

How do I request a report?

Call Alternative Energy Systems at (626) 365-1518, describe the project, and submit the current plans for review.

Are Title 24 Reports Certified?

Posted on August 4, 2026 by Title 24 Energy

Are Title 24 Reports Certified?

Call (626) 365-1518 | Alternative Energy Systems

The word “certified” is often used loosely when property owners and project teams discuss California energy-compliance documentation. Are Title 24 Reports Certified is therefore best answered by identifying exactly what the client means by certification.

A Title 24 report is a project-specific energy analysis and compliance package prepared for a proposed building design. It may include energy calculations, compliance measures, and forms intended to accompany the construction plans during permit review.

However, a report should not automatically be described as universally “certified” without explaining:

Who prepared the documentation
Which project and plan version it applies to
Which calculations and forms are included
Whether the documentation has been submitted to a building department
Whether the jurisdiction has reviewed or accepted it
Whether separate field verification is required
What professional credential, if any, the term “certified” refers to

Preparation of the report, building-department acceptance, consultant qualifications, and field verification are separate subjects. One should not be substituted for another.

Alternative Energy Systems brings more than 30 years of California energy-compliance experience to residential, multifamily, mixed-use, and commercial permit projects. AES reviews the actual plans, identifies missing information, completes the applicable analysis, and helps coordinate the resulting forms with the current design.

Call (626) 365-1518 to discuss the documentation required for your project and clarify what a contractor, architect, building department, or other party means when requesting a “certified” Title 24 report.

Are Title 24 Reports Certified or Prepared for Compliance?

A more precise description is that Title 24 reports are prepared to document how a particular building design addresses applicable California energy-efficiency requirements.

The report may contain:

Project identification information
Energy calculations
Proposed compliance measures
Building-envelope information
Window and exterior-door performance
Mechanical-system information
Ventilation requirements
Water-heating information
Residential or commercial lighting measures
Lighting-control requirements
Applicable verification measures
Compliance forms for coordination with the plans

The documentation is prepared for a specific project. Its usefulness depends on whether the calculations and forms accurately reflect the plans that will be submitted and constructed.

Calling the report “certified” does not correct inaccurate information, outdated plans, missing specifications, or conflicts between the report and drawings.

What Does “Certified Title 24 Report” Usually Mean?

Different people may use the phrase in different ways.

A homeowner may use “certified” to mean professionally prepared. A contractor may mean that the report is complete and ready to coordinate with the permit plans. A designer may be asking whether the documents include the applicable compliance forms. A building-department reviewer may be concerned with whether the submitted documentation satisfies the jurisdiction’s requirements.

The phrase may therefore refer informally to:

A report prepared by an energy-compliance professional
A completed project-specific analysis
Forms prepared for permit submittal
Documentation associated with a particular plan set
Energy measures that have been reviewed for the proposed design
A report that has already been accepted during plan review
A project involving separate field-verification requirements

These meanings are not interchangeable.

Before ordering or submitting a “certified” report, ask the requesting party to explain precisely what documentation, credential, review, or verification is required.

Does the Report Certify That the Entire Building Is Compliant?

A Title 24 report documents the energy-related design information evaluated during its preparation. It does not independently certify every part of the building or complete permit package.

The full project may also involve:

Zoning requirements
Architectural review
Structural engineering
Fire and life-safety requirements
Accessibility
Mechanical design
Electrical design
Plumbing design
CALGreen requirements
Local amendments
Building-department inspections

The energy report supports one part of the permit process. It does not replace the architectural plans, engineering documents, jurisdictional review, field inspections, or work of other professionals.

A completed report also does not guarantee that construction will match the plans. Contractors and project owners remain responsible for installing the approved products and systems properly.

Who Prepares a Title 24 Report?

A Title 24 report is prepared by an energy-compliance professional who reviews the project documents, completes the applicable analysis, and generates the required forms.

The preparation process may include:

Reviewing the proposed scope
Examining the architectural plans
Reviewing window and door information
Reviewing insulation and roof assemblies
Reviewing mechanical equipment
Reviewing duct and ventilation information
Reviewing water-heating systems
Reviewing commercial lighting and controls
Identifying missing or conflicting information
Completing project-specific calculations
Preparing the applicable forms
Coordinating the documentation with the plans

A professionally prepared report should be based on the actual project instead of a generic description or a report copied from another building.

For broader information about professional services, review the Title 24 consultants page.

Does the Consultant Have to Be Certified?

The word “certified” may refer to a specific credential, qualification, registration, training program, or role. The source information provided for this page does not establish one universal certification that applies to every person who prepares every type of Title 24 report.

Clients should ask direct questions instead of relying on a broad label.

Ask:

What experience does the consultant have?
Has the consultant handled this type of project?
What calculations and forms will be prepared?
Which plans will be reviewed?
How are revisions handled?
How are correction comments handled?
What does the consultant mean by “certified”?
Does a particular credential apply to this project?

Do not assume that a company name, marketing phrase, or informal use of “certified” proves a specific credential.

Alternative Energy Systems supports its services with more than 30 years of California energy-compliance experience. This page does not claim an unspecified professional certification for AES.

Why Experience Still Matters

A consultant must be able to interpret the construction documents and recognize when the information is incomplete or inconsistent.

Experience can help with:

Understanding different residential and commercial scopes
Identifying missing plan information
Recognizing conflicts between schedules and drawings
Evaluating existing and proposed construction
Coordinating energy measures with architects and contractors
Addressing revisions
Reviewing plan-check correction comments
Keeping the report aligned with the current design

The quality of the report depends on both the technical analysis and the project information used to prepare it.

Does the Building Department Certify the Report?

A building department reviews the permit package according to its applicable procedures. Acceptance during plan review should not be confused with a broad certification of every design, product, installation, or construction activity.

The jurisdiction may review whether:

The required forms are included
The report applies to the correct project
The project address is correct
The plans and forms are coordinated
Window information is consistent
Insulation measures appear on the drawings
Mechanical information is documented
Lighting and controls are addressed when applicable
Other permit requirements have been satisfied

The building department may approve the permit package, request revisions, or issue correction comments.

A report should not be advertised as guaranteed to receive approval. The jurisdiction controls its own review, and the complete project may involve subjects outside the energy consultant’s scope.

Does a Completed Report Guarantee Permit Approval?

No. A completed Title 24 report supports the energy-compliance portion of the permit package, but it does not guarantee approval of the entire project.

Corrections may still be issued because:

The report does not match the current plans
The project scope changed
Window schedules are inconsistent
Insulation details are incomplete
Mechanical equipment differs between documents
Ventilation information is missing
Commercial lighting controls are incomplete
Other architectural or engineering issues remain
The jurisdiction requests additional clarification

Accurate preparation and early coordination can reduce preventable inconsistencies, but no consultant can control every part of the building department’s review.

Is a Title 24 Report the Same as a Certificate?

A Title 24 report is better understood as a compliance package rather than a single general-purpose certificate.

Depending on the project, the package may include calculations and forms documenting:

Building-envelope characteristics
Window and door performance
Roofing information
HVAC efficiency
Duct location
Ventilation
Water heating
Residential lighting measures
Commercial lighting power
Lighting controls
Other applicable energy measures

The exact documentation depends on whether the project is residential or commercial and whether it involves new construction, an addition, an alteration, equipment work, lighting work, or another permit scope.

Not every project uses the same calculations or forms.

Are the Compliance Forms Certified?

The forms document the project information and energy measures used in the analysis. Whether someone describes those forms as “certified” depends on the specific requirement being discussed.

A more useful review is to confirm whether the forms:

Apply to the correct property
Identify the correct project type
Match the latest plan set
Include the applicable calculations
Identify the selected compliance measures
Reflect the specified windows and doors
Reflect the proposed insulation
Reflect the HVAC and ventilation systems
Reflect the water-heating equipment
Reflect the commercial lighting and controls when applicable

A label is less important than whether the documentation is accurate, complete, current, and suitable for the specific permit submission.

Does the Report Need to Match the Construction Plans?

Yes. The report and construction drawings must communicate the same project requirements.

The plans may show:

Conditioned floor area
Wall and roof construction
Insulation
Window sizes and locations
Exterior doors
HVAC equipment
Ductwork
Ventilation
Water heating
Lighting fixtures
Lighting controls

The report uses these details to complete the energy analysis.

A report cannot be made reliable by calling it certified when it was prepared from outdated drawings. Likewise, coordinated plans may remain incomplete for permit submittal when the applicable energy documentation has not been prepared.

What Happens if the Plans Change?

The report may need revision when the project changes after the original analysis.

Changes may include:

Conditioned floor area
Building geometry
Window sizes
Window performance values
Exterior-door specifications
Insulation values
Roof or ceiling assemblies
HVAC equipment
Duct locations
Ventilation systems
Water-heating equipment
Commercial lighting fixtures
Lighting controls
The overall permit scope

An earlier report should not be treated as applicable automatically after a significant design change.

Submit the latest plans and a written change summary so AES can determine whether the calculations or forms must be updated.

Are HERS Verification and Report Preparation the Same?

No. The energy report and field verification are separate parts of the compliance process.

The Title 24 consultant prepares the energy analysis and applicable forms. Some residential projects may also involve measures that require field testing or verification by the appropriate professional.

The report may identify measures involving:

Duct-related requirements
Airflow
Mechanical equipment
Other performance-sensitive features

However, the report itself does not substitute for:

Field testing
Construction inspections
Installation verification
Diagnostic testing
Documentation completed during construction

When someone asks whether a report is certified, determine whether that person is actually asking about separate HERS testing or field verification.

For additional context, review Title 24 vs. CALGreen.

Does Field Verification Certify the Entire Report?

Field verification addresses particular measures or installation conditions associated with the project. It should not be described as a blanket certification of the complete building, permit package, or work of every design professional.

The project team should understand:

Which measures appear in the energy report
Which measures require field verification
Who is responsible for arranging verification
When the verification must occur
What documentation must be completed

The report, plans, installation, and verification should remain coordinated throughout the project.

Are Residential Title 24 Reports Certified?

Residential reports are project-specific compliance documents prepared for homes and other residential scopes.

Projects may include:

New single-family homes
New multifamily buildings
Detached ADUs
Attached ADUs
Garage conversions
Room additions
Second-story additions
Major remodels
Window or envelope alterations
HVAC-related permit work

The residential analysis may evaluate:

Conditioned floor area
Building orientation
Wall, roof, ceiling, and floor assemblies
Window area and performance
Heating and cooling equipment
Duct locations
Mechanical ventilation
Domestic water heating
Applicable lighting measures

The most important question is whether the report is properly prepared for the current residential design—not whether someone has applied the word “certified” without defining it.

Are ADU Title 24 Reports Certified?

An ADU report is prepared for the specific accessory dwelling unit shown in the plans.

AES may need:

ADU floor plan
Exterior elevations
Building sections
Roof plan
Window and exterior-door schedule
Insulation details
HVAC specifications
Ventilation information
Water-heating details

For an attached ADU or garage conversion, the plans should distinguish the existing structure from the proposed conditioned living area.

A report prepared for a different ADU design, another property, or an outdated plan set should not be considered valid for the current project merely because it appears complete.

Visit the ADU Title 24 page for related information.

Are Commercial Title 24 Reports Certified?

Commercial reports document the applicable energy requirements for the proposed nonresidential scope.

Commercial analysis may involve:

Building-envelope performance
Mechanical systems
Ventilation
Service water heating
Interior lighting power
Exterior lighting
Lighting controls

Projects may include:

New nonresidential buildings
Office tenant improvements
Retail build-outs
Restaurant improvements
Warehouse alterations
Mixed-use projects
Commercial HVAC replacements
Interior lighting alterations
Exterior lighting projects
Multifamily common-area improvements

Commercial projects frequently require coordination among architects, mechanical engineers, electrical designers, contractors, owners, and property managers.

A commercial report should be evaluated according to its accuracy, scope, plan coordination, and suitability for the project—not an undefined certification label.

For related support, review Title 24 compliance services and Title 24 energy analysis.

What Should You Verify Before Accepting a Title 24 Report?

Before using the report for permit submittal, confirm:

The project address is correct
The client or project name is correct
The report applies to the current plan set
The occupancy and project scope are correct
The conditioned floor area is correct
The windows match the plans
The insulation matches the details
The HVAC information is current
The duct and ventilation information is accurate
The water-heating equipment is current
The commercial lighting information is coordinated
The applicable forms are included
Potential field-verification measures are understood

Contact the consultant when any information appears inconsistent.

Questions to Ask When Someone Requests a Certified Report

Ask the requesting party:

What do you mean by “certified”?
Are you requesting project-specific energy calculations?
Are you requesting completed compliance forms?
Do you need documents for a permit submittal?
Are you asking whether the building department accepted the report?
Are you asking about the consultant’s qualifications?
Are you requesting field testing or HERS verification?
Does the jurisdiction require a particular form or credential?
Does the report need to be revised for the current plans?

These questions can prevent the project team from ordering the wrong service.

Warning Signs of an Unreliable Report

Be cautious when a report:

Does not identify the correct property
Appears to have been copied from another project
Uses outdated plans
Contains floor areas that do not match the drawings
Lists different windows from the plan schedule
Uses HVAC equipment that is no longer proposed
Omits relevant commercial lighting information
Claims guaranteed permit approval
Uses “certified” without explaining the term
Ignores major design changes

A professional report should be traceable to the actual plans and specifications.

Can an Existing Report Be Reused?

An existing report may provide useful background, but it should be compared with the current project before reuse.

AES may need:

The previous report
The plan set used for that report
The latest plans
Updated product specifications
A written summary of design changes
Existing building-department comments

The report may require revision when the project changes:

Floor area
Windows
Insulation
Roofing
HVAC equipment
Ventilation
Water heating
Commercial lighting
The permit scope

An old report does not become applicable to a revised project simply because someone previously described it as certified.

Can AES Help With Plan-Check Corrections?

AES can review energy-related plan-check comments and determine whether the calculations, forms, specifications, or plan notes need attention.

Submit:

The complete correction notice
The latest architectural plans
Current mechanical plans
Current electrical and lighting plans
The previously submitted report
Updated product and equipment specifications
A written summary of changes already made

Correction comments may involve:

Missing forms
Inconsistent specifications
Incomplete plan notes
Window discrepancies
Mechanical information
Ventilation
Lighting controls
Differences between the report and drawings

Addressing the complete notice is generally more effective than reviewing one isolated comment without the surrounding project information.

Frequently Asked Questions: Are Title 24 Reports Certified?

Are Title 24 Reports Certified?

A Title 24 report is a project-specific energy analysis and compliance package. Whether someone calls it certified depends on what that term is intended to mean. Ask whether the request concerns professional preparation, permit forms, jurisdictional acceptance, consultant credentials, or field verification.

Is a Title 24 report a certificate?

It is more accurately described as an energy-compliance package containing project information, calculations, measures, and applicable forms.

Who prepares a Title 24 report?

An energy-compliance professional reviews the project documents, completes the applicable analysis, and prepares the required forms.

Does every Title 24 consultant have the same certification?

The supplied source does not establish one universal certification that applies to every consultant or project. Ask what specific qualification or credential is being requested.

Is AES certified?

This page does not claim that AES holds an unspecified certification. AES supports its services with more than 30 years of California energy-compliance experience.

Does a completed report certify the entire building?

No. The report documents the energy-related design information evaluated for the project. It does not replace architectural, structural, mechanical, electrical, plumbing, inspection, or other permit requirements.

Does the building department certify the report?

The jurisdiction reviews the permit package under its procedures. Approval or acceptance should not be confused with a blanket certification of every design and construction activity.

Does a certified report guarantee permit approval?

No. The complete project remains subject to building-department review, and correction comments may still be issued.

Does the report certify that construction was installed correctly?

No. The report is prepared from the project documents. Construction inspections and applicable field verification occur separately.

Is HERS verification included in the report?

The report may identify applicable verification measures, but field testing and verification are separate activities performed by the appropriate professional.

Are residential reports certified?

Residential reports are project-specific compliance documents. Their accuracy depends on whether they reflect the current home, ADU, addition, conversion, or remodel plans.

Are commercial reports certified?

Commercial reports document the applicable envelope, mechanical, water-heating, lighting, and control requirements for the proposed scope. The term certified should be clarified before it is used.

Can I reuse a certified report from another project?

No report should be reused automatically for a different property or design. The calculations and forms must apply to the actual project.

Can I reuse an older report for revised plans?

AES should compare the previous report with the latest plans. Changes to floor area, windows, insulation, HVAC, water heating, lighting, or scope may require revision.

What should I verify before submitting the report?

Confirm the address, plan version, project scope, floor area, windows, insulation, HVAC, ventilation, water heating, lighting, controls, and applicable forms.

What should I ask when someone requests a certified report?

Ask whether the person needs professional calculations, permit forms, building-department acceptance, a specific consultant credential, or separate field verification.

Does the report replace the architectural plans?

No. The report evaluates energy-related information within the design and must remain coordinated with the construction plans.

How do I request a Title 24 report?

Call Alternative Energy Systems at (626) 365-1518, describe the project, and submit the current plans for review.

What Is the Process After Requesting a Title 24 Report?

Posted on August 4, 2026 by Title 24 Energy

What Is the Process After Requesting a Title 24 Report?

Call (626) 365-1518 | Alternative Energy Systems

Requesting a Title 24 report begins a professional review process rather than an instant document-generation step. What Is the Process After Requesting a Title 24 Report is an important question for homeowners, contractors, architects, designers, developers, property managers, and business owners who need California energy-compliance documentation for a permit project.

After the initial request, Alternative Energy Systems reviews the project description and available plans to determine what type of analysis is needed. AES may then request additional information involving windows, insulation, roofing, HVAC equipment, ducts, ventilation, water heating, commercial lighting, controls, or other energy-related features.

Once the required information is available, AES completes the applicable energy calculations, evaluates the proposed compliance measures, prepares the necessary forms, and helps identify the information that must remain coordinated with the construction plans.

The process may also include a project-specific quote, payment instructions, design clarifications, revisions, or assistance with building-department correction comments.

Alternative Energy Systems brings more than 30 years of California energy-compliance experience to residential, multifamily, mixed-use, and commercial permit projects. Call (626) 365-1518 to request a report, submit your plans, or ask what happens next for your specific project.

What Is the Process After Requesting a Title 24 Report From AES?

The general process includes the following stages:

Project request and initial intake
Scope and document review
Request for missing or conflicting information
Quote, authorization, and payment instructions
Energy calculations and compliance review
Preparation of the applicable forms
Coordination with the current plan set
Delivery of the completed documentation
Revisions or correction support when required

The exact workflow depends on the project.

A detached ADU does not necessarily follow the same calculation path as a commercial restaurant improvement. A residential addition may require coordination with an existing home, while a commercial tenant improvement may involve separate architectural, mechanical, electrical, lighting, and control documents.

AES reviews the actual project before defining the complete scope.

Step 1: AES Receives the Initial Request

The process begins when the client contacts Alternative Energy Systems and describes the proposed work.

The initial request may be made by:

A homeowner
A property owner
A contractor
An architect
A building designer
A developer
A property manager
A business owner
An authorized project representative

The request should identify the basic project type and explain why the report is needed.

Projects may include:

New residential construction
New commercial construction
An attached or detached ADU
A garage conversion
A room addition
A second-story addition
A residential remodel
A multifamily improvement
A commercial tenant improvement
An HVAC replacement
A lighting or lighting-control project
A plan-check correction response
A revision to an existing report

A brief description such as “I need Title 24” may start the conversation, but AES will need more information before determining the service, price, and schedule.

Information to Include in the Initial Request

Provide:

Project address
Permit jurisdiction
Residential or commercial property type
Description of the proposed work
Approximate project size
Current design stage
Requested completion date
Primary contact person
Whether plans are available
Whether a previous report exists
Whether correction comments have been issued

This information helps AES understand what should be reviewed first.

Step 2: The Project Scope Is Confirmed

After the request is received, AES evaluates the stated scope.

The project scope determines:

Whether the work is residential or nonresidential
Whether it involves new construction or an alteration
Which building areas are conditioned
Which building components are affected
Which mechanical or lighting systems are involved
Which calculations may apply
Which compliance forms may be required

The scope must be clear because Title 24 documentation is tied to the proposed work.

For example, a residential remodel that replaces interior finishes may have a different energy scope from a remodel that changes exterior walls, windows, insulation, roofing, HVAC equipment, and conditioned floor area.

A commercial lighting alteration may have a different scope from a complete tenant improvement that also modifies ventilation, mechanical equipment, service water heating, and the building envelope.

Why Scope Confirmation Matters

An incomplete scope can affect:

The project quote
The required plans
The calculation method
The applicable forms
The turnaround estimate
The need for later revisions

Describe the complete proposed work before the analysis begins.

Step 3: The Current Plans Are Submitted

AES generally needs the current construction documents before completing the project review.

Whenever possible, submit one clearly identified PDF plan set rather than numerous separate sheets with unclear filenames.

The plan set may include:

Cover sheet and project data
Site plan
Existing floor plans
Proposed floor plans
Exterior elevations
Building sections
Roof plan
Wall, roof, ceiling, and floor details
Window and exterior-door schedules
Mechanical plans
Electrical and lighting plans
Equipment schedules
Relevant construction notes

The plans should be readable and should represent the current design.

If several versions exist, identify which file AES should use.

Use Clear Filenames

A useful filename might include:

Project address
Document type
Plan or revision date

For example:

123-Main-Street-Current-Plans-2026-08-04.pdf
123-Main-Street-Window-Schedule.pdf
123-Main-Street-HVAC-Specifications.pdf

Avoid filenames such as:

Final-Plans.pdf
Final-Plans-2.pdf
New-Attachment.pdf
Scan0001.pdf

Clear filenames help reduce confusion when plans are revised.

Step 4: AES Reviews the Plans and Specifications

AES examines the available documents to determine whether the project contains the information needed for the energy analysis.

The review may address:

Conditioned floor area
Building orientation
Wall construction
Roof and ceiling assemblies
Floor assemblies
Insulation values
Window sizes and locations
Window performance
Exterior doors
Roofing characteristics
HVAC equipment
Duct locations
Ventilation systems
Water-heating equipment
Residential lighting measures
Commercial lighting and controls

The purpose of this stage is to understand the actual building design and identify whether the plans are coordinated.

Existing and Proposed Work Must Be Clear

For additions, remodels, garage conversions, and attached ADUs, the plans should distinguish:

Existing conditioned space
Existing unconditioned space
New conditioned space
Removed construction
New walls and openings
Existing systems that remain
New or replaced equipment

Unclear project boundaries can delay the analysis or cause the wrong building area to be evaluated.

Step 5: Missing or Conflicting Information Is Identified

After the initial plan review, AES may send questions or request additional documents.

Common missing items include:

Window dimensions
Window U-factors
Window solar heat gain coefficients
Exterior-door specifications
Wall insulation
Roof insulation
Ceiling and attic details
HVAC system type
Heating and cooling efficiencies
Duct-location information
Ventilation specifications
Water-heating information
Commercial fixture wattage
Lighting-control details

Conflicting information may also require clarification.

Examples include:

Floor areas that differ between sheets
Window schedules that do not match elevations
Mechanical equipment that differs between the notes and schedules
Insulation values that differ between sections and details
Lighting schedules that do not match the electrical plans

AES can identify the conflict, but the architect, designer, contractor, engineer, owner, or supplier may need to provide the final design decision.

Step 6: The Client Responds to Information Requests

The project can move forward when the missing details are supplied.

Responses should be based on updated plans, schedules, or product specifications rather than informal guesses.

When an item remains undecided, state that clearly.

For example:

The final windows have not been selected
The HVAC model is pending
The architect is revising the roof assembly
The lighting designer is updating the control plan
The contractor is confirming the duct location

This allows AES to distinguish between confirmed project information and pending design decisions.

Who Should Answer Technical Questions?

The appropriate contact may be:

The architect
The building designer
The mechanical engineer
The electrical designer
The contractor
The equipment supplier
The owner

Identify the person authorized to make or confirm design decisions.

Step 7: The Quote and Service Scope Are Confirmed

AES can provide a project-specific quote after enough information is available to understand the work.

The quote may consider:

Project type
Building size
Calculation complexity
Plan completeness
Number of building systems
Requested turnaround
Previous reports
Design revisions
Plan-check corrections

Review the quote for:

Project address
Service description
Calculation scope
Expected forms or deliverables
Turnaround information
Revision terms
Correction-response terms
Payment amount
Payment instructions

Do not assume that every project includes unlimited revisions, expedited scheduling, third-party testing, permit fees, or all future correction cycles.

Review Title 24 report pricing in California for additional pricing information.

Step 8: Payment Is Completed When Arranged

Payment should follow the instructions provided for the specific project.

When the service and amount have already been arranged, payment may be completed through the AES payment page.

Before paying, confirm:

Client name
Project address
Approved amount
Service being purchased
Applicable quote or invoice
Payment deadline

The payment page should not replace the initial quote and project-review process.

Call (626) 365-1518 when the amount or payment timing has not been confirmed.

Step 9: AES Completes the Energy Calculations

Once the necessary information is available and the project has been authorized, AES can complete the applicable energy analysis.

The calculations may evaluate:

Building geometry
Conditioned floor area
Building orientation
Wall, roof, ceiling, and floor assemblies
Insulation values
Window area and performance
Exterior doors
Heating and cooling equipment
Duct locations
Ventilation
Water heating
Residential lighting measures
Commercial lighting power
Lighting-control systems

The required calculations depend on the occupancy, project scope, construction details, and applicable compliance approach.

For more information, review the Title 24 energy calculations page.

Step 10: The Proposed Design Is Evaluated

The analysis determines whether the proposed building features support the applicable compliance requirements.

The project may move directly to form preparation when the design and documentation are sufficient.

In other cases, the analysis may identify an issue requiring clarification or adjustment.

Potential areas of review include:

Window performance
Window area
Insulation values
Roof construction
HVAC efficiency
Duct location
Water-heating equipment
Commercial lighting power
Lighting controls

AES can explain which part of the design requires attention. The project team then determines which practical change should be incorporated into the plans.

Design Changes May Require Additional Review

A change made during the calculation stage may affect several parts of the report.

For example:

Resizing windows may change the envelope analysis
Selecting different HVAC equipment may change mechanical information
Changing the roof assembly may affect insulation and roofing measures
Changing commercial fixtures may affect lighting-power calculations

Send revised information promptly so AES does not continue using an outdated design.

Step 11: The Compliance Forms Are Prepared

After the energy analysis is completed, AES prepares the applicable project-specific forms.

The documentation may identify:

Project information
Building characteristics
Envelope measures
Window performance
Mechanical systems
Ventilation
Water heating
Lighting measures
Control requirements
Applicable verification measures

The exact forms depend on the project type and scope.

A new home, addition, commercial tenant improvement, HVAC alteration, and lighting project may use different documentation.

Step 12: The Report Is Coordinated With the Plans

The report and plans must describe the same project.

AES may identify measures that should appear in the construction documents. The architect, designer, contractor, or responsible project professional should confirm that the plan set reflects those requirements.

Review the documents for consistency involving:

Project address
Conditioned floor area
Window sizes
Window performance
Insulation
Roof characteristics
HVAC equipment
Duct locations
Ventilation systems
Water-heating equipment
Commercial lighting
Lighting controls

A technically correct report based on an old plan set may still create a permit problem.

The report does not replace the construction plans. It works with them as part of the permit package.

Step 13: The Completed Report Is Delivered

After the calculations, forms, and coordination review are complete, AES provides the project documentation according to the arranged service.

The client should review the delivered files for:

Correct project address
Correct client or project identification
Current plan version
Expected forms
Identified energy measures
Any notes requiring plan updates

Report any obvious project-identification issue promptly.

The architect, designer, contractor, owner, or permit coordinator can then incorporate the documentation into the broader permit-submittal package.

What Happens After the Report Is Delivered?

Delivery of the report does not necessarily end the project’s complete permit process.

The next steps may include:

Adding the forms to the permit package
Updating plan notes and schedules
Submitting the package to the building department
Responding to plan-check comments
Updating the report after design revisions
Coordinating field-verification requirements

The exact responsibility for submission should be confirmed with the project team.

The architect, designer, contractor, owner, or permit coordinator may be responsible for submitting the complete plans.

Does AES Submit the Permit Package?

Preparing a Title 24 report does not automatically mean that AES submits the entire building-permit application or acts as the project’s permit expediter.

The complete permit package may include:

Architectural plans
Structural documents
Mechanical plans
Electrical plans
Plumbing plans
CALGreen documentation
Title 24 forms
Jurisdictional applications

Confirm who is responsible for:

Uploading the complete plans
Paying permit and plan-check fees
Tracking the application
Receiving correction comments
Coordinating responses from each design professional

Do not assume that these administrative services are included unless the written proposal states otherwise.

What Happens if the Building Department Issues Corrections?

The building department may request clarification or identify a conflict involving the energy documentation.

Energy-related comments may involve:

Missing forms
Inconsistent window information
Missing insulation notes
Mechanical-equipment discrepancies
Ventilation questions
Water-heating information
Commercial lighting power
Lighting controls
Differences between the report and plans

Send AES:

The complete correction notice
The latest architectural plans
Current mechanical plans
Current electrical and lighting plans
The previously submitted report
Updated product specifications
A written summary of revisions already made

AES can review the complete package and determine whether the response requires a clarification, revised calculation, updated form, or change to the plans.

What Happens if the Plans Change After the Report?

The report may need to be revised when the design changes.

Updates may be necessary when the project changes:

Conditioned floor area
Building geometry
Window sizes
Window performance
Insulation
Roofing
HVAC equipment
Duct locations
Ventilation
Water heating
Commercial lighting
Lighting controls
The overall permit scope

Submit:

The previous report
The latest plan set
Updated specifications
A written change summary
The requested revision date

A report based on superseded plans should not be submitted with the revised permit set.

What Is the Process After Requesting a Title 24 Report for an ADU?

The ADU process follows the same general workflow, but the project documents must identify whether the unit is detached, attached, or converted from existing space.

AES may need:

ADU floor plan
Exterior elevations
Building sections
Roof plan
Window and exterior-door schedule
Insulation details
HVAC specifications
Ventilation information
Water-heating details

For an attached ADU or garage conversion, the plans should distinguish existing construction from the new conditioned living area.

The process may involve:

Reviewing the ADU scope
Confirming the existing and proposed areas
Reviewing windows and envelope assemblies
Reviewing HVAC, ventilation, and water heating
Completing the residential calculations
Preparing the applicable forms
Coordinating the measures with the ADU plans

Visit the ADU Title 24 page for related information.

What Is the Process for an Addition or Remodel?

For an addition or remodel, AES must understand what exists and what will change.

The plans should identify:

Existing conditioned space
New conditioned space
Removed and proposed walls
New or replaced windows
New insulation
Roof and ceiling alterations
Existing or new HVAC systems
Duct extensions
Ventilation changes
Water-heating changes

The report process may be delayed when the existing and proposed conditions are not clearly separated.

A remodel should also identify whether the work is cosmetic or affects energy-related building components.

What Is the Process After Requesting a Commercial Title 24 Report?

Commercial projects may require coordination among several design disciplines.

AES may review:

Architectural plans
Building-envelope details
Mechanical plans
HVAC equipment schedules
Ventilation information
Service water-heating information
Electrical plans
Lighting fixture schedules
Lighting-control plans

Commercial projects may include:

New nonresidential buildings
Office tenant improvements
Retail build-outs
Restaurant improvements
Warehouse alterations
Mixed-use projects
Commercial HVAC replacements
Interior lighting projects
Exterior lighting projects
Multifamily common-area improvements

The process may require questions to be directed to separate architectural, mechanical, electrical, plumbing, or lighting contacts.

For related services, review Title 24 compliance services and Title 24 energy analysis.

Does the Process Include HERS Testing?

The Title 24 report may identify measures requiring field testing or verification.

The consultant prepares the energy analysis and applicable forms. Field testing or verification is completed separately by the appropriate professional.

The report process does not automatically include:

Duct-leakage testing
Airflow verification
Refrigerant-charge verification
Fan testing
Construction inspections
Other field-verification services

Not every project has the same verification requirements.

The completed report can help the project team identify which measures may apply during construction.

Review Title 24 vs. CALGreen for additional information about overlapping compliance subjects.

How Long Does the Process Take?

Turnaround depends on:

Project type
Building size
Building geometry
Calculation complexity
Completeness of the plans
Availability of specifications
Response time for missing information
Requested design changes
Plan-check corrections
Requested priority scheduling

A coordinated project with complete information can generally move more efficiently than one requiring repeated clarification.

The total calendar time may include periods when AES is waiting for:

Updated plans
Window information
Insulation details
Equipment selections
Lighting schedules
Answers from the project team

Call (626) 365-1518 to discuss a schedule based on the actual project.

How Can You Keep the Process Moving?

Clients can reduce avoidable delays by following several practical steps.

Submit One Current Plan Set

Clearly identify the current file and avoid sending several superseded versions without explanation.

Provide a Complete Scope

Explain every energy-related part of the proposed work.

Include Available Specifications

Submit window, insulation, HVAC, ventilation, water-heating, lighting, and control information when available.

Identify Pending Decisions

Tell AES which products or systems remain undecided.

Respond Promptly

Direct technical questions to the correct architect, designer, contractor, engineer, or supplier.

Report Design Changes Early

Do not wait until the report is complete to disclose major revisions.

Send Complete Correction Notices

Provide the entire notice and the latest plan set rather than one isolated comment.

Common Problems That Interrupt the Process

Frequent issues include:

No clear project description
Missing floor plans
Conflicting square footage
Several unidentified plan versions
Window schedules that do not match the elevations
Missing window performance values
Undefined insulation assemblies
Unclear roof construction
Undecided HVAC equipment
Missing duct information
Incomplete ventilation details
Missing water-heating specifications
Incomplete commercial lighting schedules
Missing lighting controls
Repeated design changes
Correction notices submitted without current plans

Providing a large number of files does not necessarily create a complete submission. The documents must be current, readable, relevant, and coordinated.

Frequently Asked Questions: What Is the Process After Requesting a Title 24 Report?

What Is the Process After Requesting a Title 24 Report?

AES reviews the project scope and plans, identifies missing information, confirms the service, completes the applicable energy calculations, prepares the forms, and helps coordinate the report with the current plan set.

What happens immediately after I contact AES?

AES needs basic information about the property, proposed work, current design stage, permit jurisdiction, requested schedule, and available plans.

Do I need to submit plans before receiving a report?

Yes. Project-specific calculations and forms generally require current plans and applicable building-system information.

What documents should I send?

Helpful documents include floor plans, elevations, sections, roof plans, window schedules, insulation details, HVAC specifications, ventilation, water heating, commercial lighting plans, and correction notices when applicable.

What happens if information is missing?

AES can identify the missing details and explain what must be provided before the calculations or final forms can be completed.

Who answers technical questions?

The architect, designer, contractor, engineer, owner, or equipment supplier may need to answer questions depending on the subject.

When is the project quote prepared?

A meaningful quote can be prepared after AES has enough information to understand the project scope, calculation complexity, documents, requested schedule, and revision needs.

When do I pay?

Payment should follow the project-specific quote or invoice. The AES payment page may be used after the service and amount have been arranged.

What happens during the calculation stage?

AES evaluates the applicable building envelope, windows, HVAC systems, ducts, ventilation, water heating, lighting, controls, and other project-specific energy features.

What happens if the design does not work as proposed?

AES can identify the area requiring attention. The project team can then determine which practical design adjustment should be made.

What happens after the calculations are completed?

AES prepares the applicable forms, reviews the project information, and identifies measures that should remain coordinated with the permit plans.

Does AES prepare the architectural plans?

The energy report works with the architectural plans. Complete architectural design or drafting should not be assumed unless separately arranged.

Does AES submit the entire permit package?

Not automatically. Confirm whether the architect, designer, contractor, owner, or permit coordinator is responsible for submission.

What happens if the building department issues corrections?

Send AES the complete correction notice, latest plans, previous report, updated specifications, and a summary of changes already made.

What happens if the plans change?

The report may need to be revised so the calculations and forms remain aligned with the current design.

Does the process include HERS testing?

The report may identify field-verification measures, but testing and inspections are separate services performed by the appropriate professional.

How long does the process take?

Timing depends on project type, complexity, plan completeness, available specifications, response time, revisions, and correction requirements.

Does receiving the report guarantee permit approval?

No. The report supports the energy-compliance portion of the permit package, but the complete project remains subject to building-department review.

How Long Do Title 24 Calculations and Reports Take?

Posted on August 4, 2026 by Title 24 Energy

How Long Do Title 24 Calculations and Reports Take?

Call (626) 365-1518 | Alternative Energy Systems

A Title 24 project involves both technical energy calculations and the preparation of a coordinated compliance report. How Long Do Title 24 Calculations and Reports Take depends on the building type, proposed work, calculation complexity, quality of the plans, availability of specifications, and whether the design changes during the review.

The energy calculations cannot be completed accurately from an address and approximate square footage alone. The consultant must understand the building geometry, conditioned spaces, envelope assemblies, windows, mechanical systems, ventilation, water heating, lighting, controls, and other applicable energy features.

After the calculations are completed, the results must be converted into the appropriate compliance forms and coordinated with the current permit plans. Missing specifications, conflicting drawings, revised products, and unresolved design decisions can extend the total calendar schedule.

Alternative Energy Systems brings more than 30 years of California energy-compliance experience to residential, multifamily, mixed-use, and commercial projects. AES reviews project documents electronically and provides scheduling information based on the actual scope rather than an unsupported universal turnaround.

Call (626) 365-1518 to submit your plans, discuss the requested completion date, and receive a project-specific review.

How Long Do Title 24 Calculations and Reports Take for a Specific Project?

There is no single timeline that applies to every project.

A straightforward residential project with coordinated drawings and complete specifications can generally move through the calculation and report-preparation stages more efficiently than a complex commercial building with multiple systems, incomplete schedules, and several design disciplines.

Turnaround may be affected by:

Residential or commercial occupancy
New construction, addition, conversion, or alteration
Building size and geometry
Number of conditioned spaces
Number of stories
Complexity of the building envelope
Window area, orientation, and performance
Number and type of HVAC systems
Duct locations
Ventilation systems
Water-heating design
Commercial lighting and controls
Completeness of the plans
Availability of product specifications
Unresolved design questions
Requested revisions
Existing plan-check corrections
Requested priority or expedited scheduling

AES must review the project documents before confirming a meaningful turnaround.

The Calculation Timeline and Report Timeline Are Connected

Title 24 calculations and the final report are related, but they are not the same stage of work.

The calculation phase evaluates the proposed building and systems. The report phase documents the selected compliance measures and produces the forms used with the permit package.

A typical workflow may involve:

Reviewing the project scope
Reviewing the architectural and engineering documents
Identifying missing information
Receiving clarification from the project team
Completing the applicable energy calculations
Evaluating the proposed compliance results
Resolving design changes when needed
Preparing the compliance forms
Reviewing the forms for consistency
Coordinating the report with the current plans

A project may move quickly through the technical calculation stage but remain incomplete because a window schedule, equipment specification, or lighting-control plan still needs to be updated.

The complete turnaround therefore includes more than the time spent operating compliance software.

What Happens Before the Calculations Begin?

AES first reviews the project to determine what is being proposed and which energy-related components may need to be evaluated.

The initial review may identify whether the work involves:

A new single-family home
A new multifamily building
An attached or detached ADU
A garage conversion
A residential addition
A major remodel
A commercial tenant improvement
A new nonresidential building
An HVAC alteration
A commercial lighting project
A revision to an existing report
A response to plan-check corrections

The project scope affects the calculations, forms, and required source documents.

A short description such as “remodel” may not be enough. AES needs to know whether the work changes conditioned floor area, exterior walls, windows, insulation, roofing, HVAC equipment, ventilation, water heating, lighting, or controls.

How Long Does the Initial Plan Review Take?

The initial review determines whether the submitted plans contain enough information to begin the calculations.

AES may review:

Cover sheet and project information
Site plan
Existing floor plans
Proposed floor plans
Exterior elevations
Building sections
Roof plans
Wall, roof, ceiling, and floor details
Window and exterior-door schedules
Mechanical plans
Electrical and lighting plans
Equipment schedules
Previous Title 24 documentation
Plan-check correction notices

A complete, readable, and clearly labeled submission generally moves through the review more efficiently than a collection of separate files with conflicting dates.

The review may take longer when:

Several plan versions are submitted
The current version is not identified
Existing and proposed construction are unclear
Floor areas conflict between sheets
Plan dimensions are missing
Product schedules do not match the drawings

How Missing Information Affects the Total Timeline

The calculations may remain pending while the consultant waits for project information.

Common missing items include:

Window dimensions
Window U-factors
Window solar heat gain coefficients
Exterior-door information
Wall insulation values
Roof and ceiling assemblies
Floor insulation
HVAC equipment efficiency
Duct-location information
Ventilation specifications
Water-heating equipment
Commercial fixture wattage
Lighting-control details

AES can identify what is missing, but the architect, designer, contractor, engineer, owner, or equipment supplier may need to provide the answer.

The waiting period between the consultant’s question and the project team’s response becomes part of the total calendar turnaround.

Active Work Time Is Different From Calendar Time

The consultant’s active review and calculation time should be distinguished from the overall period between the initial request and final delivery.

The calendar schedule may include time spent waiting for:

Updated plans
A corrected window schedule
Final insulation selections
HVAC equipment specifications
Ventilation information
Water-heating selections
Commercial lighting schedules
Lighting-control plans
Architect or contractor responses
Approval of a proposed design adjustment

A project can remain open even when AES has completed all work possible with the information currently available.

Clients can reduce avoidable delays by submitting the current plans and responding promptly to document requests.

How Long Do the Energy Calculations Take?

Calculation time depends on the amount of building information that must be entered, reviewed, and evaluated.

The calculations may address:

Building orientation
Conditioned floor area
Exterior wall areas
Roof and ceiling assemblies
Floor assemblies
Insulation values
Window sizes and orientations
Window performance
Exterior doors
Roofing characteristics
Heating equipment
Cooling equipment
Duct location
Mechanical ventilation
Water heating
Residential lighting measures
Commercial lighting power
Lighting controls

A project with one clearly defined building envelope and one HVAC system can require less calculation work than a building with several conditioned zones, roof types, window groups, and mechanical systems.

Review the Title 24 energy calculations page for additional information.

How Building Geometry Affects Calculation Time

The size of the building matters, but square footage alone does not determine the timeline.

Geometry can become more complex when the project includes:

Multiple stories
Several building wings
Irregular exterior walls
Multiple ceiling heights
Vaulted ceilings
Several roof types
Raised floors
Floors over garages
Attached existing and proposed construction
Mixed conditioned and unconditioned areas

Each condition may need to be interpreted from the plans and represented correctly in the analysis.

A smaller but geometrically complex project may take more calculation time than a larger building with a simple, repetitive layout.

How Window Information Affects Calculation Time

Windows can affect both energy performance and data-entry requirements.

AES may need to confirm:

Window identification numbers
Width and height
Quantity
Orientation
U-factor
Solar heat gain coefficient
Frame type when applicable
Glazed exterior doors

The calculation stage may be delayed when:

The window schedule does not match the elevations
Several windows have missing dimensions
Performance values have not been selected
The design team is comparing several products
Window sizes change after the analysis begins

Submitting one coordinated schedule can help reduce clarification time.

How Insulation and Roof Assemblies Affect Calculation Time

The consultant must identify the thermal boundary of the proposed building.

The plans may need to define:

Exterior wall insulation
Continuous insulation
Roof insulation
Ceiling insulation
Attic configuration
Vaulted ceiling assemblies
Raised-floor insulation
Floors over unconditioned areas
Walls adjoining garages
Roofing characteristics

A general note such as “insulate per code” may not contain enough information for a project-specific calculation.

The project team may need to clarify the actual construction assembly before the analysis can be completed.

How Mechanical Systems Affect Calculation Time

Mechanical-system complexity can influence the calculation schedule.

AES may need information about:

Heating-system type
Cooling-system type
Number of systems
Equipment efficiencies
Heat-pump characteristics
Equipment locations
Ducted or ductless configurations
Duct locations
Duct insulation
Areas served by each system

A project with one complete equipment schedule can generally be reviewed more efficiently than a building with several undecided systems.

Changes to mechanical equipment after the initial calculations may require the analysis and forms to be updated.

How Ventilation and Water Heating Affect the Schedule

Ventilation and water-heating systems may also affect the calculations.

Ventilation information may include:

Whole-building ventilation
Local exhaust
Outdoor-air systems
Ventilation-equipment specifications
Airflow information
Control sequences

Water-heating information may include:

Equipment type
Fuel or energy source
Efficiency
Storage or tankless configuration
Heat-pump water heating
Equipment location
Individual or central service

The report may remain incomplete until these systems are defined.

How Long Does It Take to Prepare the Report After the Calculations?

Completing the calculations does not always mean the final report is ready for delivery.

After the analysis, AES may need to:

Review the calculated compliance results
Confirm the selected compliance measures
Prepare the applicable forms
Check project addresses and identification information
Confirm equipment and product data
Verify that the forms reflect the current plan set
Identify measures that must appear on the plans
Organize the compliance package for delivery

If the analysis shows that a proposed design requires adjustment, the project team may need to approve a change before the forms can be finalized.

Potential adjustments may involve:

Window performance
Window area
Insulation
Roof characteristics
HVAC efficiency
Water-heating equipment
Commercial lighting power
Lighting controls

The report-preparation stage is therefore part of the professional compliance process rather than a simple document-export step.

How Plan Coordination Affects Final Delivery

The report and permit plans should describe the same project.

Before final delivery or permit submittal, the documents may need to be checked for consistency involving:

Conditioned floor area
Window sizes
Window performance values
Insulation
Roof and ceiling assemblies
HVAC equipment
Duct locations
Ventilation systems
Water-heating equipment
Commercial lighting fixtures
Lighting controls

A technically complete calculation based on outdated drawings may still create a permitting problem.

The architect, designer, contractor, or responsible project professional should update the plans when the report identifies measures that must be shown in the permit set.

How Long Do Residential Title 24 Calculations and Reports Take?

Residential timing depends on the project design and available information.

Residential work may include:

New single-family homes
New multifamily buildings
Detached ADUs
Attached ADUs
Garage conversions
Room additions
Second-story additions
Major residential remodels
Window and envelope alterations
HVAC-related permit projects

A straightforward residential project may move more efficiently when it includes:

One current plan set
Clearly identified conditioned space
A coordinated window schedule
Defined insulation assemblies
Selected HVAC equipment
Complete ventilation information
Defined water-heating equipment

Custom designs with several rooflines, extensive glazing, multiple systems, and changing specifications may require additional calculation and coordination time.

How Long Do ADU Calculations and Reports Take?

ADU turnaround depends on whether the unit is attached, detached, or created through a garage conversion.

AES may need:

ADU floor plan
Exterior elevations
Building sections
Roof plan
Window and door schedule
Insulation details
HVAC specifications
Ventilation information
Water-heating details

A detached ADU with complete plans may be more straightforward than a garage conversion where existing wall, slab, roof, window, and mechanical conditions remain unclear.

An attached ADU may also require coordination with the existing residence.

Visit the ADU Title 24 page for related information.

How Long Do Addition Calculations and Reports Take?

Addition timing depends on the new conditioned area and how the addition connects to the existing building.

The plans should identify:

Existing conditioned space
New conditioned space
Removed and proposed walls
New windows and doors
Roof and ceiling assemblies
Existing HVAC equipment
Extended ducts or new systems
Ventilation changes
Water-heating changes

The schedule may be extended when the plans do not clearly separate existing conditions from proposed construction.

How Long Do Commercial Title 24 Calculations and Reports Take?

Commercial projects may require coordination among several design disciplines.

The analysis may involve:

Building-envelope components
Mechanical systems
Ventilation
Service water heating
Interior lighting power
Exterior lighting
Lighting controls

Commercial projects may include:

New nonresidential buildings
Office tenant improvements
Retail build-outs
Restaurant improvements
Warehouse alterations
Mixed-use projects
Commercial HVAC replacements
Interior lighting projects
Exterior lighting projects
Multifamily common-area improvements

AES may need to review architectural, mechanical, electrical, lighting, control, and water-heating documents.

Commercial turnaround may be affected when the separate disciplines show different project information or remain under design.

For related support, review Title 24 compliance services and Title 24 energy analysis.

How Commercial Lighting Affects the Timeline

Commercial lighting calculations may require:

Lighting floor plans
Fixture schedules
Fixture identification numbers
Fixture wattage
Fixture quantity
Room or space use
Occupancy sensors
Automatic shutoff controls
Daylighting controls
Exterior lighting information

A complete and coordinated lighting package can generally be analyzed more efficiently than a plan set with missing fixture wattage or undefined controls.

Revised fixtures or room layouts may require the lighting calculations and forms to be updated.

How Long Do Revisions Take?

Revision timing depends on the extent of the change.

A limited revision may involve:

Updating one product specification
Correcting a project reference
Clarifying a limited plan note

A substantial revision may involve:

Changing conditioned floor area
Changing building geometry
Resizing several windows
Changing window performance
Revising insulation assemblies
Changing HVAC systems
Relocating ducts
Changing water heating
Revising commercial lighting
Expanding the overall permit scope

The original turnaround estimate should not be assumed to apply after a major design change.

Submit the newest plan set and a written summary of all revisions so AES can determine which calculations and forms require attention.

How Long Do Plan-Check Corrections Take?

Correction-response timing depends on what the building department requested and whether the calculations, forms, plans, or specifications must change.

Correction comments may involve:

Missing compliance forms
Differences between the plans and report
Incomplete window information
Missing insulation details
Mechanical-equipment discrepancies
Ventilation questions
Water-heating information
Commercial lighting power
Lighting controls
Outdated calculations

Submit:

The complete correction notice
The latest architectural plans
Current mechanical plans
Current electrical and lighting plans
The previously submitted report
Updated product specifications
A summary of changes already made

AES can then determine whether the response requires a limited clarification or broader recalculation.

Can Calculations Begin Before the Plans Are Complete?

AES can review preliminary plans and identify missing information while the project remains under design.

Preliminary review may help the project team address:

Window performance
Insulation assemblies
Roof characteristics
HVAC equipment
Duct locations
Ventilation
Water heating
Commercial lighting
Lighting controls

The final calculations and report still require enough information to represent the proposed project accurately.

Starting early can provide time to resolve missing design details before the planned permit-submittal date.

Does Expedited Service Reduce the Timeline?

Priority scheduling may shorten the consultant’s queue when it is available and approved for the project. It does not remove the need for complete information.

Before requesting expedited service, provide:

The current plan set
A clear description of the scope
Window and door information
Insulation and roof details
HVAC specifications
Ventilation information
Water-heating information
Commercial lighting documents when applicable
The requested completion date
The planned permit-submittal date

Ask AES whether priority scheduling is available and whether an additional fee applies.

A rush request submitted with missing plans or undecided systems may still remain pending until the required information is supplied.

How Can You Reduce the Turnaround?

Clients and project teams can help the calculations and report move more efficiently.

Send One Current Plan Set

Identify the current file clearly and remove superseded versions from the submission when possible.

Provide a Written Project Summary

Explain:

What is being built or changed
Whether the project is residential or commercial
Whether the plans are preliminary or permit-ready
Whether an earlier report exists
Whether corrections have been issued
When the report is needed

Include Available Specifications

Submit window, insulation, HVAC, ventilation, water-heating, lighting, and control information with the plans.

Identify Pending Decisions

Tell AES which products or systems have not been selected.

Respond to Questions Promptly

Route technical questions to the appropriate architect, designer, engineer, contractor, or supplier.

Send Design Changes Before Finalization

Early notice can prevent calculations from being completed using an outdated design.

Common Problems That Extend the Timeline

Frequent causes of delay include:

No clear project description
Missing floor plans
Conflicting square footage
Several unidentified plan versions
Window schedules that do not match the elevations
Missing window performance values
Undefined insulation assemblies
Unclear roof construction
Undecided HVAC equipment
Missing duct-location information
Incomplete ventilation details
Missing water-heating specifications
Incomplete commercial lighting schedules
Missing lighting-control information
Repeated design revisions
Correction notices submitted without current plans

The number of files submitted is less important than whether the information is current, readable, complete, and coordinated.

When Should You Order the Calculations and Report?

Contact AES after the project has enough information to define the building envelope and major systems, but before the permit documents are treated as final.

Early involvement provides time to address:

Window selections
Insulation
Roof assemblies
HVAC equipment
Duct locations
Ventilation
Water heating
Commercial lighting
Lighting controls

Waiting until the intended permit-submittal date leaves little time for calculation questions, design adjustments, report preparation, or plan coordination.

Does the Timeline Include Building-Department Review?

The Title 24 calculation and report timeline does not control how long the building department takes to review the complete permit application.

After the report is delivered, the jurisdiction may still review:

Zoning
Architectural plans
Structural engineering
Fire and life safety
Accessibility
Mechanical plans
Electrical plans
Plumbing plans
CALGreen requirements
Energy-compliance documentation
Other local requirements

A completed Title 24 report does not guarantee a particular building-department review period or prevent all correction comments.

How Does Turnaround Affect Pricing?

The requested schedule may affect the project quote, particularly when expedited service is requested and available.

Pricing may also depend on:

Project type
Building size
Calculation complexity
Plan completeness
Number of systems
Previous reports
Design revisions
Plan-check corrections

Review Title 24 report pricing in California or call AES for a project-specific quote and schedule.

Frequently Asked Questions: How Long Do Title 24 Calculations and Reports Take?

How Long Do Title 24 Calculations and Reports Take?

Timing depends on the project type, building size, geometry, calculation complexity, plan completeness, available specifications, unresolved design questions, and whether revisions or corrections are involved.

Are the calculations and report completed at the same time?

The calculations support the compliance results. The forms and report package are then prepared and reviewed for consistency with the plans.

Can AES confirm a timeline before reviewing the plans?

A reliable schedule generally requires enough project information to understand the calculation and documentation scope.

Does a small building always take less time?

No. A small but complex project with incomplete plans or several systems may require more coordination than a larger, straightforward building.

Can calculations be completed from an address and square footage?

No. AES needs the current plans and applicable building-system specifications.

What information helps the process move faster?

Submit floor plans, elevations, sections, roof plans, window schedules, insulation details, HVAC specifications, ventilation, water heating, commercial lighting information, and correction comments when applicable.

Can the calculations begin with preliminary plans?

Preliminary review can begin, but final calculations and forms require enough detail to represent the proposed design accurately.

How long do residential calculations and reports take?

Residential timing depends on the project size, envelope, windows, HVAC systems, ventilation, water heating, and completeness of the plans.

How long do ADU calculations and reports take?

The schedule depends on whether the ADU is attached, detached, or converted from existing space, along with the available building and system information.

How long do addition calculations and reports take?

Timing depends on the new conditioned area, relationship to the existing building, windows, insulation, roof assemblies, HVAC systems, and plan quality.

How long do commercial calculations and reports take?

Commercial timing depends on occupancy, envelope, mechanical systems, ventilation, service water heating, lighting, controls, and coordination among the plans.

Does missing information delay both calculations and reports?

Yes. The calculations may remain pending, and the final forms cannot be completed accurately until essential information is available.

Do project changes extend the timeline?

They can. Changes to floor area, windows, insulation, HVAC systems, water heating, lighting, or the permit scope may require recalculation and updated forms.

How long do revisions take?

Revision timing depends on the extent of the change. Updating one specification differs from recalculating a redesigned envelope or mechanical system.

How long do plan-check corrections take?

The timeline depends on the complete correction notice and whether the calculations, forms, plans, or specifications need revision.

Is expedited service available?

Ask AES whether priority scheduling is available for the project. Complete plans and specifications are still required.

Does expedited service guarantee completion by a specific deadline?

No deadline should be assumed until AES reviews the plans, confirms availability, and identifies missing information.

Does the timeline include building-department plan review?

No. The jurisdiction controls its own review schedule after the permit package is submitted.

How can I reduce avoidable delays?

Submit one current plan set, provide complete specifications, identify pending decisions, respond to questions promptly, and report design changes before finalization.

How Long Does It Take to Generate a Title 24 Report?

Posted on August 4, 2026 by Title 24 Energy

How Long Does It Take to Generate a Title 24 Report?

Call (626) 365-1518 | Alternative Energy Systems

The time required to prepare California energy-compliance documentation depends on the project and the quality of the information submitted. How Long Does It Take to Generate a Title 24 Report cannot be answered accurately with one universal turnaround because a small residential alteration, custom home, ADU, commercial tenant improvement, and complex mixed-use project do not require the same level of analysis.

A straightforward project with coordinated plans, complete window data, clearly defined insulation assemblies, and selected mechanical equipment can generally move more efficiently than a project with missing specifications, conflicting drawings, undecided systems, or repeated design changes.

The process also involves more than automatically generating forms. A Title 24 consultant must review the scope, examine the construction documents, identify missing information, complete the applicable energy calculations, prepare the compliance forms, and coordinate the resulting measures with the permit plans.

Alternative Energy Systems has more than 30 years of California energy-compliance experience with residential, multifamily, mixed-use, and commercial projects. AES can review project documents electronically for clients throughout California.

Call (626) 365-1518 to discuss your plans, requested schedule, and the information needed before a project-specific turnaround can be confirmed.

How Long Does It Take to Generate a Title 24 Report for a Specific Project?

The schedule depends on several connected factors:

Residential or commercial property type
New construction, addition, conversion, or alteration
Building size and geometry
Number of conditioned spaces
Complexity of the building envelope
Window area, orientation, and performance
Number and type of mechanical systems
Duct and ventilation information
Water-heating systems
Commercial lighting and controls
Completeness of the submitted plans
Availability of product specifications
Number of unresolved design questions
Requested revisions
Existing plan-check corrections
Consultant availability and requested priority

AES must review the actual project before providing a useful schedule.

A completion estimate based only on the property address or approximate square footage may overlook important project conditions. Two buildings of similar size may require different amounts of calculation and coordination work.

Why There Is No Universal Title 24 Report Turnaround

Every report is prepared around a different building design.

One project may include:

A simple rectangular floor plan
One roof assembly
A complete window schedule
One HVAC system
Clearly identified insulation values
No prior corrections or revisions

Another project may include:

Several connected building sections
Multiple stories
Several roof and ceiling conditions
Numerous window types
Multiple mechanical systems
Mixed existing and proposed construction
Incomplete lighting or control information
Previous calculations based on outdated plans

Even when the buildings have similar square footage, the second project can require substantially more document review and calculation work.

The project schedule should therefore reflect the actual design rather than a generic promise.

What Does “Generate a Title 24 Report” Actually Involve?

The word “generate” may sound as though the report is produced immediately after basic information is entered into a program. In practice, a professional report requires several stages.

1. Review the Project Scope

AES first determines what work is proposed.

The project may involve:

A new residence
A new commercial building
An attached or detached ADU
A garage conversion
A room addition
A residential remodel
A multifamily improvement
A commercial tenant improvement
An HVAC alteration
A commercial lighting project
A correction response
A revision to an existing report

The scope determines which building components, systems, calculations, and forms may apply.

2. Review the Current Plans

AES examines the available construction documents to understand the building and identify energy-related details.

The plan review may include:

Floor plans
Exterior elevations
Building sections
Roof plans
Wall and roof details
Window and door schedules
Mechanical plans
Electrical and lighting plans
Product and equipment schedules

The review cannot move efficiently when several conflicting plan versions are submitted without identifying which one is current.

3. Identify Missing Information

The consultant may need clarification before the calculations can be completed.

Missing information may involve:

Conditioned floor area
Window sizes or performance values
Insulation assemblies
Roof characteristics
HVAC efficiency
Duct location
Ventilation systems
Water-heating equipment
Commercial lighting wattage
Lighting controls

The time required to receive these details becomes part of the overall calendar schedule, even though the consultant may be waiting for the project team to respond.

4. Complete the Energy Calculations

Once enough information is available, AES can evaluate the energy-related features of the design.

The analysis may account for:

Building orientation
Conditioned floor area
Wall, roof, ceiling, and floor assemblies
Window area and performance
Exterior doors
Heating and cooling equipment
Duct location
Mechanical ventilation
Water heating
Residential lighting measures
Commercial lighting power and controls

Review the Title 24 energy calculations page for additional information about the technical analysis.

5. Prepare the Compliance Forms

The applicable forms are produced after the project information and compliance measures have been evaluated.

The forms should reflect the current design—not an outdated plan set or a generic property description.

6. Coordinate the Report With the Plans

The project team should confirm that the plans and report describe the same building.

The documents should remain consistent regarding:

Floor area
Windows
Insulation
Roof assemblies
HVAC equipment
Ducts
Ventilation
Water heating
Commercial lighting
Lighting controls

A calculation may be technically complete but still require coordination when the plans show different products or systems.

Consultant Work Time and Total Calendar Time Are Different

The active time required to review plans and complete calculations is not always the same as the total time between the initial request and final delivery.

The overall calendar schedule may include time spent waiting for:

A complete plan set
Revised architectural drawings
Window specifications
Insulation details
Mechanical equipment selections
Ventilation information
Water-heating specifications
Commercial lighting schedules
Lighting-control information
Answers from the architect or contractor
Approval of a proposed design change

For example, AES may identify a missing HVAC specification during the initial review. The report may remain pending until the architect, mechanical designer, contractor, owner, or equipment supplier provides the necessary information.

Submitting complete information early can reduce this waiting period.

How Plan Completeness Affects the Schedule

Complete plans allow the consultant to identify the building and systems with less back-and-forth.

A useful submission may include:

Cover sheet and project data
Site plan
Existing and proposed floor plans
Exterior elevations
Building sections
Roof plan
Wall, roof, ceiling, and floor details
Window and door schedules
Mechanical plans
Electrical and lighting plans
Equipment specifications

Common plan problems that may extend the schedule include:

Missing dimensions
Conflicting floor areas
Unclear existing and proposed construction
Windows that differ between plans and elevations
Missing insulation values
Undefined roof assemblies
Incomplete HVAC schedules
Missing lighting controls
Several unlabeled plan versions

Before submitting the project, review what AES will need from you.

How Window Information Affects Turnaround

Windows and glazed doors must be represented accurately in the analysis.

Helpful information includes:

Window identification numbers
Width and height
Quantity
Orientation
U-factor
Solar heat gain coefficient
Frame type when relevant
Glazed exterior doors

Turnaround may be affected when:

The schedule does not match the elevations
Window sizes are missing
Performance values have not been selected
Several window options are still being considered
The window design changes during the analysis

Submitting a coordinated window schedule can help AES complete the report more efficiently.

How Insulation and Roof Details Affect Turnaround

The report must reflect the proposed building envelope.

AES may need details for:

Exterior walls
Roofs
Ceilings
Attics
Vaulted ceilings
Floors over unconditioned spaces
Raised floors
Walls adjoining garages or other unconditioned areas

A general note such as “insulate per code” may not contain enough information for a project-specific calculation.

The schedule may be extended when the architect or designer must first clarify:

Stud size
Insulation value
Continuous insulation
Roof insulation location
Attic configuration
Roofing characteristics

How HVAC Information Affects the Timeline

Heating and cooling information can be an important part of residential and commercial calculations.

AES may need:

System type
Number of systems
Manufacturer and model when selected
Heating efficiency
Cooling efficiency
Heat-pump information
Equipment location
Ducted or ductless configuration
Duct location
Duct insulation

The report may remain pending when the project team has not selected the equipment or determined whether existing systems will remain.

Mechanical changes made after the calculations are completed can also require additional review.

How Ventilation and Water Heating Affect the Timeline

The consultant may need information about ventilation and water heating before the documentation can be finalized.

Ventilation information may include:

Whole-building ventilation
Local exhaust
Outdoor-air systems
Equipment specifications
Airflow information
Controls

Water-heating information may include:

Equipment type
Fuel or energy source
Efficiency
Storage, tankless, or heat-pump configuration
Equipment location
Individual or central service

When these systems remain undecided, AES may be able to review the project but may not be able to complete the final report.

How Long Does a Residential Title 24 Report Take?

Residential turnaround depends on the size, design, systems, and completeness of the project information.

Residential projects may include:

New single-family homes
New multifamily buildings
Detached ADUs
Attached ADUs
Garage conversions
Room additions
Second-story additions
Major remodels
Window and envelope alterations
HVAC-related permit projects

A straightforward residential project with coordinated drawings and selected equipment can generally move more efficiently than a custom design with several roof conditions, extensive glazing, multiple HVAC systems, and incomplete product information.

AES must review the current plans before confirming the schedule.

How Long Does an ADU Title 24 Report Take?

An ADU schedule depends on whether the unit is detached, attached, or converted from existing space.

Helpful documents include:

ADU floor plan
Exterior elevations
Building sections
Roof plan
Window and door schedule
Insulation details
HVAC specifications
Ventilation information
Water-heating details

A detached ADU with a complete plan set may be more straightforward to evaluate than a garage conversion where the existing walls, slab, roof, windows, and mechanical conditions remain unclear.

Attached ADUs may also require information showing how the new living area relates to the existing residence.

Visit the ADU Title 24 page for related project information.

How Long Does an Addition Report Take?

The schedule for an addition depends on the amount of new conditioned space and the relationship between the addition and the existing building.

AES may need information showing:

Existing floor area
New conditioned floor area
Removed and proposed walls
New windows and doors
Roof and ceiling assemblies
Existing HVAC equipment
Extended ducts or new equipment
Ventilation changes
Water-heating changes

The schedule may be extended when the plans do not clearly distinguish existing and proposed construction.

How Long Does a Remodel Report Take?

Remodel turnaround depends on which energy-related components are changing.

A remodel may affect:

Conditioned floor area
Exterior walls
Windows and doors
Insulation
Roofing
HVAC equipment
Ductwork
Ventilation
Water heating

A limited remodel may require less analysis than a project involving major envelope and mechanical changes.

Describe the complete scope when requesting a turnaround estimate. An incomplete description may result in a schedule that no longer applies after the full plans are reviewed.

How Long Does a Commercial Title 24 Report Take?

Commercial and nonresidential projects may require coordination among architectural, mechanical, electrical, lighting, plumbing, and control documents.

Commercial work may include:

New nonresidential buildings
Office tenant improvements
Retail build-outs
Restaurant improvements
Warehouse alterations
Mixed-use projects
Commercial HVAC replacements
Interior lighting alterations
Exterior lighting projects
Multifamily common-area improvements

AES may need to review:

Architectural plans
Building-envelope details
Mechanical plans
HVAC equipment schedules
Ventilation information
Service water-heating information
Electrical plans
Lighting fixture schedules
Lighting-control plans

Commercial turnaround may be affected when these documents conflict or when different project professionals are still finalizing their designs.

For related support, review Title 24 compliance services and Title 24 energy analysis.

How Commercial Lighting Information Affects Turnaround

Commercial lighting analysis may require:

Lighting floor plans
Fixture schedules
Fixture identification numbers
Fixture wattage
Fixture quantity
Room or space use
Occupancy sensors
Automatic shutoff controls
Daylighting controls
Exterior lighting information

A complete fixture schedule and coordinated control plan can help the analysis move forward.

The schedule may be delayed when fixture wattage is missing, room uses are unclear, or control requirements have not been designed.

How Project Changes Affect Completion Time

The estimated turnaround is normally based on the design available when the project is reviewed.

The report may need additional work when the project changes:

Conditioned floor area
Building geometry
Window sizes
Window performance values
Wall or roof assemblies
Insulation values
HVAC equipment
Duct locations
Ventilation systems
Water-heating equipment
Commercial lighting fixtures
Lighting controls
The overall permit scope

A minor product clarification may require less time than a redesign that changes the building envelope, floor area, or mechanical system.

Send revised plans with a written change summary so AES can evaluate the effect on the report and schedule.

How Long Do Report Revisions Take?

Revision timing depends on the extent of the changes.

A limited revision may involve:

Updating one product specification
Correcting a plan reference
Clarifying a limited project detail

A substantial revision may involve:

Changing conditioned floor area
Resizing several windows
Changing insulation assemblies
Selecting different HVAC systems
Changing the water-heating design
Revising commercial lighting and controls
Expanding the permit scope

The original schedule should not be assumed to apply after a major redesign.

AES must review the revised plans and determine what calculations and forms need to be updated.

How Long Does It Take to Address Plan-Check Corrections?

Correction-response timing depends on the complete building-department notice and whether the project plans or calculations must change.

Corrections may involve:

Missing compliance forms
Differences between the report and plans
Incomplete window information
Missing insulation details
Mechanical-equipment discrepancies
Ventilation questions
Water-heating information
Commercial lighting power
Lighting controls
Outdated calculations

Submit:

The complete correction notice
The latest architectural plans
Current mechanical plans
Current electrical and lighting plans
The previously submitted report
Updated product specifications
A summary of revisions already made

One isolated correction comment may not provide enough context to estimate the required work.

AES can review the complete package and explain whether the response requires a limited clarification or broader recalculation.

Can AES Begin Before the Plans Are Complete?

AES can review preliminary plans and identify missing information before every product and system has been selected.

Early review may help the project team recognize unresolved items involving:

Windows
Insulation
Roofing
HVAC equipment
Duct locations
Ventilation
Water heating
Commercial lighting
Lighting controls

The final report still requires enough information to complete the calculations accurately.

Starting early can reduce the risk of discovering missing energy details immediately before permit submittal.

Does Expedited Service Shorten the Turnaround?

Priority or expedited scheduling may shorten the consultant’s queue when it is available and arranged in advance. It does not eliminate the need for complete project information.

Before requesting expedited service, provide:

The current plan set
The complete project scope
Window and door information
Insulation and roof details
HVAC specifications
Ventilation information
Water-heating information
Commercial lighting documents when applicable
The requested completion date
The planned permit-submittal date

Ask AES whether priority scheduling is available for the specific project and whether it affects the fee.

A rush request submitted with incomplete plans may still require additional time while missing details are resolved.

How Can You Help the Report Move Faster?

Clients can reduce avoidable delays by preparing a coordinated submission.

Send One Current Plan Set

Do not send several plan versions without identifying the current file.

Include the plan date or revision date in the filename.

Provide a Clear Project Summary

Explain:

What is being built or altered
Whether the project is residential or commercial
Whether the plans are preliminary or permit-ready
Whether a previous report exists
Whether corrections have been issued
When the documentation is needed

Include Available Specifications

Submit window, insulation, HVAC, ventilation, water-heating, and commercial lighting information with the plans.

Identify Unresolved Decisions

Tell AES which products or systems have not been selected.

This is more useful than presenting preliminary information as final.

Respond Promptly to Questions

The report may remain pending while AES waits for missing information.

Route technical questions to the architect, designer, contractor, or responsible consultant as quickly as practical.

Report Design Changes Immediately

Do not wait until the report is complete to disclose significant revisions.

Early notification can reduce work performed on an outdated design.

Common Issues That Delay a Title 24 Report

Frequent causes of delay include:

No clear project description
Missing floor plans
Conflicting square footage
Several unidentified plan versions
Window schedules that do not match the plans
Missing window performance values
Undefined insulation assemblies
Unclear roof construction
Undecided HVAC equipment
No duct-location information
Missing ventilation details
No water-heating specifications
Incomplete commercial lighting schedules
Missing lighting-control information
Repeated design revisions
Correction notices submitted without the current plans

A large number of files does not necessarily create a complete submission. The documents must be current, relevant, readable, and coordinated.

When Should You Request the Report?

Contact AES after the project has enough design information to identify the building envelope and major systems, but before the permit package is treated as final.

Starting at this stage allows time to resolve questions involving:

Window performance
Insulation assemblies
Roof characteristics
HVAC equipment
Duct location
Ventilation
Water heating
Commercial lighting
Lighting controls

Waiting until the intended permit-submittal date leaves little time for missing information, design revisions, or plan coordination.

The report should be incorporated into the project schedule rather than treated as paperwork that can always be generated immediately at the end.

Does Report Completion Mean the Permit Is Approved?

No. Completion of the Title 24 report means the energy-compliance documentation has been prepared for coordination with the current plans.

The complete permit package may still require review of:

Zoning
Architecture
Structural engineering
Fire and life safety
Accessibility
Mechanical plans
Electrical plans
Plumbing plans
CALGreen requirements
Other jurisdiction-specific issues

The building department controls its own review schedule.

A completed Title 24 report does not guarantee that the jurisdiction will complete plan check within a particular period or issue no corrections.

How Much Does Turnaround Affect the Price?

The requested schedule may affect the quote, especially when priority handling is requested and available.

Pricing may also depend on:

Project type
Building size
Calculation complexity
Plan completeness
Number of systems
Previous reports
Design revisions
Plan-check corrections

Review Title 24 report pricing in California or call AES for a project-specific quote and schedule.

Frequently Asked Questions: How Long Does It Take to Generate a Title 24 Report?

How Long Does It Take to Generate a Title 24 Report?

Turnaround depends on the project type, building size, complexity, completeness of the plans, available specifications, unresolved design questions, and whether revisions or plan-check corrections are involved.

Can AES provide an exact turnaround before reviewing the plans?

A reliable schedule generally requires enough project information to understand the scope and calculation complexity.

Does a small project always take less time?

Not necessarily. A small project with incomplete plans, unusual geometry, extensive windows, or unresolved equipment may require more coordination than a larger but straightforward project.

Can a report be completed from the property address alone?

No. The consultant needs current plans and applicable specifications to prepare project-specific calculations and forms.

What documents help the report move faster?

Submit current floor plans, elevations, sections, roof plans, window schedules, insulation details, HVAC specifications, ventilation, water heating, commercial lighting information, and correction comments when applicable.

Can AES begin with preliminary plans?

Yes. Preliminary review can identify missing information, but the final report requires enough detail to represent the proposed design accurately.

How long does an ADU report take?

The schedule depends on whether the ADU is attached, detached, or converted from existing space, along with plan completeness, windows, envelope assemblies, HVAC, ventilation, and water heating.

How long does an addition report take?

Timing depends on the new conditioned area, relationship to the existing home, window information, insulation, roof conditions, HVAC systems, and completeness of the plans.

How long does a commercial report take?

Commercial turnaround depends on the project size, occupancy, envelope, mechanical systems, ventilation, water heating, lighting, controls, and coordination among the design documents.

Does missing information affect the schedule?

Yes. The report may remain pending while AES waits for window data, insulation details, equipment specifications, ventilation information, lighting schedules, or other required information.

Do design changes extend the turnaround?

They can. A change to floor area, windows, insulation, HVAC equipment, water heating, lighting, or the overall scope may require revised calculations and forms.

How long do revisions take?

Revision timing depends on the extent of the changes. Updating one specification is different from recalculating a redesigned building envelope or mechanical system.

How long do plan-check corrections take?

The schedule depends on the complete correction notice and whether the forms, calculations, plans, or specifications must be updated.

Is expedited service available?

Ask AES whether priority scheduling is available for the specific project. Complete plans and specifications are still required.

Does expedited service guarantee completion by my deadline?

No schedule should be assumed until AES reviews the project, confirms availability, and identifies any missing information.

Does completing the report mean the permit is approved?

No. The report supports the energy-compliance portion of the application, but the complete project remains subject to building-department review.

How can I reduce delays?

Submit one current plan set, provide complete specifications, identify unresolved decisions, answer questions promptly, and report design changes before the calculations are finalized.

How do I request a turnaround estimate?

Call Alternative Energy Systems at (626) 365-1518, describe the project, and submit the current plans for review.

What Payment Methods Do Title 24 Consultants Accept?

Posted on August 4, 2026 by Title 24 Energy

What Payment Methods Do Title 24 Consultants Accept?

Call (626) 365-1518 | Alternative Energy Systems

Payment options can vary among energy-compliance providers, so clients should confirm the accepted method before attempting to pay an invoice. What Payment Methods Do Title 24 Consultants Accept is best answered by reviewing the consultant’s written quote, invoice, or official payment instructions.

Alternative Energy Systems provides an online AES payment page for clients whose services have already been arranged. The project scope, amount due, and payment instructions should be confirmed before using that page.

The available source information does not identify individual card brands, electronic bank transfers, checks, cash, digital wallets, financing programs, or installment plans as accepted AES payment methods. Clients should therefore contact AES directly rather than assuming that a particular option is available.

Call (626) 365-1518 to:

Confirm the amount due
Verify which project the payment applies to
Ask which payment methods are currently accepted
Request an invoice or payment instructions
Confirm whether payment is due before work begins
Ask how revisions or additional services are billed

Alternative Energy Systems brings more than 30 years of California energy-compliance experience to residential, multifamily, mixed-use, and commercial permit projects.

What Payment Methods Do Title 24 Consultants Accept for Professional Services?

Payment methods are determined by the individual consultant or company. The accepted options should appear on the proposal, invoice, payment page, or written instructions supplied to the client.

Before paying, ask whether the consultant accepts:

Online payment through an official company payment page
Credit or debit card payments
Electronic bank payments
Checks
Bank transfers
Other approved business-payment methods

This list represents questions to ask rather than a statement that every consultant accepts every option.

Alternative Energy Systems confirms that arranged services may be paid through the official AES payment page. Contact AES for confirmation of the specific payment method available for your transaction.

Do not send payment information through an unfamiliar link, an unverified email address, or a payment request that does not identify your project.

Use the Official AES Payment Page After Service Is Arranged

The AES payment page should be used after the project and service have been discussed.

Before opening the payment page, confirm:

The client or company name
The project address
The approved service
The amount due
The applicable quote or invoice
The payment deadline
Whether the payment covers a new report or a revision
Whether expedited service is included

The payment page is not a substitute for the project-review and quote process.

A client who has not yet received a price should first provide the project plans and scope information. AES can review the material, determine the work required, and provide the appropriate next steps.

Call (626) 365-1518 when you are unsure whether your service has been arranged or which payment amount applies.

Why Should Payment Methods Be Confirmed in Advance?

Confirming the accepted method can prevent delays when a project is ready to begin.

Payment problems can occur when a client:

Assumes a payment method is accepted without asking
Sends money before receiving a quote
Uses an outdated payment link
Pays an amount intended for a different project
Submits payment without identifying the property address
Assumes a deposit arrangement that was never approved
Expects an installment plan that was not offered
Pays a third-party permit fee through the consultant’s payment page

A short confirmation can establish the correct payment channel and reduce the risk of the transaction being associated with the wrong service.

What Information Should Be Included With a Payment?

A payment should be connected clearly to the correct client and project.

Include or confirm:

Client name
Company name when applicable
Project address
Invoice or quote number when provided
Payment amount
Service description
Email address
Telephone number
Any reference information requested by AES

A payment submitted without the project address or client name may be more difficult to match with the correct report.

Use consistent identifying information across the plans, quote, invoice, payment, and project correspondence.

Should You Pay Before Receiving a Quote?

A client should generally understand the proposed service and amount before submitting payment.

The report price may depend on:

Residential or commercial use
New construction, addition, conversion, or alteration
Building size
Building geometry
Window and door information
Insulation and roof assemblies
HVAC systems
Duct locations
Ventilation
Water heating
Commercial lighting and controls
Plan completeness
Requested turnaround
Existing reports or corrections

AES may need to review the current plans before confirming the price.

Do not select an arbitrary payment amount based on the cost of another project. Two projects with similar square footage may involve different calculations, systems, documentation, and revision requirements.

How Do You Request a Title 24 Quote Before Paying?

Begin by providing a clear project description and the current documents.

Helpful information includes:

Project address
Permit jurisdiction
Property type
Description of the proposed work
Current architectural plans
Approximate project size
Window and door schedule
Insulation information
Roof details
HVAC specifications
Duct-location information
Ventilation details
Water-heating information
Commercial lighting documents when applicable
Requested completion date
Previous Title 24 reports
Building-department correction notices

AES can review what is available and explain what additional information is needed before the report can be completed.

Review what AES will need from you before submitting the project.

Does AES Accept Credit or Debit Cards?

The supplied material does not identify which card types or brands are accepted through the AES payment page.

Clients should not assume that every credit card, debit card, prepaid card, or commercial purchasing card will be accepted.

Before paying, ask:

Whether card payments are currently available
Which card types are accepted
Whether the cardholder name must match the client
Whether billing information is required
Whether a transaction limit applies
Whether a receipt will be issued

Use only the official payment instructions provided by AES.

Does AES Accept Electronic Bank Payments?

The supplied material does not confirm whether AES accepts ACH payments, direct bank transfers, electronic checks, or wire transfers.

Clients who prefer a bank-based payment should contact AES before initiating a transaction.

Ask for:

Confirmation that the requested method is accepted
Official payment instructions
The correct business or account name
The amount due
The project reference to include
Confirmation procedures after payment

Do not send funds to banking details received from an unfamiliar or unverified source.

Call (626) 365-1518 to confirm payment instructions directly.

Do Title 24 Consultants Accept Checks?

Some professional-service businesses may offer check payments, while others rely primarily on electronic payment systems.

The available AES source material does not confirm that personal checks, business checks, cashier’s checks, or mailed payments are accepted.

Before preparing or mailing a check, confirm:

Whether checks are accepted
The correct payee name
The correct mailing address
The project reference that should appear on the check
Whether work begins before or after the check clears
Whether the payment deadline allows mailing time

Do not mail payment to an address that has not been verified by AES.

Do Title 24 Consultants Accept Cash?

The source does not state that AES accepts cash payments.

Cash can be difficult to document and should never be sent through the mail.

When a consultant allows an in-person cash payment, the client should request a written receipt identifying:

The amount received
The date
The client name
The project address
The service covered
The remaining balance, when applicable

Contact AES directly before assuming that cash is an approved payment option.

Do Title 24 Consultants Accept Digital Wallets?

The source does not identify digital wallets, peer-to-peer payment applications, cryptocurrency, or other alternative payment platforms as accepted AES methods.

Do not send funds to a username, telephone number, QR code, wallet address, or payment handle unless AES has directly confirmed that it is official and connected to your project.

A legitimate payment request should identify:

The consultant or company
The project
The amount
The service
The official payment channel

Contact AES using the published phone number when a payment request differs from the instructions you previously received.

Do Title 24 Consultants Offer Payment Plans?

The available source material does not confirm that AES offers installment plans, financing, deferred payment, or split-payment arrangements.

Do not assume that a project can be divided into payments unless the arrangement is approved in writing.

Ask whether:

Full payment is required
A deposit is required
A balance is due before delivery
Milestone payments are available
A revision requires separate payment
Expedited work requires advance payment

The written quote or invoice should control the payment schedule.

Can a Contractor, Architect, or Property Manager Pay?

The person ordering the report and the person making the payment may not always be the same.

A project may be paid for by:

The property owner
A homeowner
A general contractor
An architect
A building designer
A developer
A property manager
A business owner
An authorized company representative

When a third party pays, the payment should still identify the correct project address and client.

AES should be informed when:

The payer name differs from the client name
The invoice must be issued to a company
The receipt must be sent to another contact
The payer is responsible only for part of the project

Clear information helps prevent the payment from being applied to another client or address.

What Payment Methods Apply to Residential Reports?

Residential clients should follow the payment instructions issued for their individual project.

Residential reports may involve:

New single-family homes
New multifamily buildings
Detached ADUs
Attached ADUs
Garage conversions
Room additions
Second-story additions
Major remodels
Window and envelope alterations
HVAC-related permit work

The payment method may be the same across several services, but the amount and payment schedule can differ according to the project.

Do not use the amount from a previous report or another property without receiving confirmation.

Payment for an ADU Report

An ADU quote may depend on:

Attached or detached construction
New or converted conditioned space
Building size
Window area and performance
Wall and roof assemblies
HVAC system
Ventilation
Water-heating equipment
Plan completeness

After AES reviews the ADU documents and confirms the service, follow the supplied payment instructions.

Visit the ADU Title 24 page for related project information.

Payment for an Addition or Remodel

An addition or remodel may change during design. Confirm that the payment amount corresponds to the latest plans.

Inform AES when the project adds:

More conditioned floor area
Additional windows
New roof conditions
Different HVAC equipment
Expanded mechanical work
Additional permit scope

A payment made for the original scope may not automatically cover a substantially revised project.

What Payment Methods Apply to Commercial Reports?

Commercial clients should also use the method approved for their project.

Commercial services may involve:

New nonresidential buildings
Office tenant improvements
Retail build-outs
Restaurant improvements
Warehouse alterations
Mixed-use projects
Commercial HVAC replacements
Interior lighting projects
Exterior lighting projects
Multifamily common-area improvements

A company paying for commercial work may require:

An invoice issued to the legal business name
A billing contact
A purchase-order reference
A project or job number
A receipt sent to an accounting department

Provide these requirements before payment whenever possible.

For related services, review Title 24 compliance services and Title 24 energy analysis.

How Do You Pay for a Report Revision?

A revision may be covered by the original agreement or may require a separate quote and payment.

Revisions may be needed when the project changes:

Conditioned floor area
Building geometry
Window sizes
Window performance values
Wall or roof assemblies
Insulation
HVAC equipment
Duct locations
Ventilation systems
Water-heating equipment
Commercial lighting fixtures
Lighting controls
The overall permit scope

Before paying for a revision:

Submit the latest plans
Provide the previous report

Request a revision quote
Confirm the payment method
Confirm the new turnaround

Do not submit an additional payment without identifying which revision or project version it covers.

How Do You Pay for Plan-Check Correction Support?

Plan-check correction work may be included, limited, or quoted separately.

Submit the following before requesting payment instructions:

The complete correction notice
The latest architectural plans
Current mechanical plans
Current electrical and lighting plans
The previously submitted Title 24 report
Updated product specifications
A written summary of revisions already completed

AES can review the correction and determine whether additional work must be authorized.

Correction comments may involve:

Missing compliance forms
Differences between the plans and report
Incomplete window information
Missing insulation details
Mechanical-equipment discrepancies
Ventilation questions
Water-heating information
Commercial lighting power
Lighting controls
Outdated calculations

Once the scope is confirmed, follow the payment instructions provided for the correction service.

How Do You Pay for Expedited Service?

Expedited or priority service should be confirmed before payment.

Ask AES to identify:

Whether expedited scheduling is available
The project information required
The requested completion date
The expedited fee when applicable
The payment deadline
The accepted payment method

A rush payment does not replace missing project information.

The report cannot be completed accurately without enough detail about the building envelope, windows, HVAC systems, ventilation, water heating, lighting, and controls.

Are Government and Third-Party Fees Paid Through the AES Payment Page?

Do not assume that the AES payment page should be used for every charge connected with the permit process.

Separate charges may include:

Building-permit fees
Plan-check fees
Government processing charges
Inspection fees
HERS testing
Field verification
Third-party registration
Architectural services
Engineering services
Contractor labor and materials

The AES payment page should be used only for the AES service that has been arranged.

Contact the building department or applicable third party for its own payment instructions.

How Can You Verify a Payment Request?

Payment fraud and misdirected transactions can be reduced by verifying unexpected instructions.

Before paying, confirm:

The request came from AES
The project address is correct
The amount matches the quote or invoice
The payment page or instructions are official
The service description is accurate
The payment deadline is expected

Use the published AES contact information rather than replying only to an unfamiliar message.

Be cautious when a request:

Changes the payment destination unexpectedly
Asks for payment to an individual rather than the arranged business channel
Uses an unfamiliar web address
Does not identify the project
Requests an amount different from the quote
Creates unusual pressure to pay immediately

Call AES directly when any information appears inconsistent.

Will You Receive a Payment Confirmation?

Keep documentation showing that the transaction was completed.

Payment records may include:

A payment-page confirmation
An emailed receipt
An invoice marked as paid
A bank or card transaction record
Written confirmation from AES

The source does not specify which receipt format AES provides for every payment method.

When confirmation is not received, contact AES and provide:

Client name
Project address
Date of payment
Amount paid
Transaction or confirmation reference

Do not send complete card numbers, account passwords, or unrelated financial records by ordinary email.

What Happens if a Payment Fails?

A failed or declined transaction does not necessarily mean that the invoice is incorrect.

Possible causes may include:

Incorrect billing information
An expired payment method
A card or account limit
A security hold
An interrupted internet connection
An unsupported payment method

Contact the payment provider when the issue appears connected to the account or card. Contact AES when the amount, invoice, payment page, or project reference appears incorrect.

Do not repeatedly submit a payment without checking whether an earlier attempt was processed.

What Happens if You Pay the Wrong Amount?

Contact AES promptly when:

The payment amount differs from the invoice
The payment was made for the wrong address
The payment was submitted twice
The payment was intended for another service
The project scope changed before payment

Provide the transaction information and project details needed to identify the payment.

Do not assume that an overpayment will automatically be applied to future revisions or unrelated work. Confirm how the payment will be handled.

When Do You Pay for a Title 24 Report?

Posted on August 4, 2026 by Title 24 Energy

When Do You Pay for a Title 24 Report?

Call (626) 365-1518 | Alternative Energy Systems

Payment should be handled according to the terms provided for the specific project rather than an assumed schedule that applies to every client. When Do You Pay for a Title 24 Report is therefore best answered after Alternative Energy Systems reviews the proposed work, confirms the service scope, and provides the applicable quote or payment instructions.

A new home, ADU, addition, residential remodel, commercial tenant improvement, HVAC alteration, lighting project, correction response, and report revision may each involve a different amount of analysis and coordination. Payment timing may also depend on whether the project is a new assignment, an urgent request, a revision to existing calculations, or additional work outside the original scope.

Clients should review the written quote, invoice, or payment request before submitting funds. Those documents should identify the amount due, the service being authorized, and the applicable payment timing.

When service has already been arranged, payment may be completed through the AES payment page.

Alternative Energy Systems brings more than 30 years of California energy-compliance experience to residential, multifamily, mixed-use, and commercial permit projects. Call (626) 365-1518 to discuss your project, request a quote, and confirm when payment is due.

When Do You Pay for a Title 24 Report Through AES?

You should pay according to the instructions associated with your approved project scope. The supplied project quote or invoice should control the payment schedule.

Before making a payment, confirm:

The project address
The name of the client or company ordering the service
The type of Title 24 service requested
The quoted amount
The plans or project version covered by the quote
Whether the service involves a new report or a revision
Whether plan-check correction support is included
Whether expedited service is included
The stated payment deadline
The approved payment method

Do not assume that every Title 24 project follows the same payment arrangement. The report scope can vary substantially based on the building type, size, available documents, systems involved, requested turnaround, and number of revisions.

If you have not yet received a quote or instructions, call AES before using the payment page.

Do You Pay Before the Title 24 Report Is Started?

Whether payment is due before work begins should be stated in the project-specific quote, invoice, or service instructions.

A consultant may need to review the submitted plans before confirming the scope. That initial review helps determine whether the project involves:

A new residential report
A new commercial report
Residential performance calculations
Commercial envelope calculations
Mechanical-system analysis
Commercial lighting calculations
A revision to an existing report
Plan-check correction assistance
An expedited turnaround request

The amount and payment timing should not be based only on a brief description such as “ADU report” or “commercial Title 24.”

AES may need to review the current plans and available specifications before defining what work is required. Once the scope and price are established, the client can follow the payment instructions provided for that project.

Request a Quote Before Paying

A project-specific quote helps ensure that the requested payment corresponds to the actual service.

To request a quote, provide:

Project address
Permit jurisdiction
Residential or commercial property type
Description of the proposed work
Current architectural plans
Approximate project size
Window and exterior-door information
Insulation and roof details
HVAC specifications
Duct-location information
Ventilation details
Water-heating information
Commercial lighting documents when applicable
Requested turnaround
Previous Title 24 reports
Existing plan-check correction notices

The quote may be based on the information supplied at that time. If the project later becomes larger, more complex, or substantially different, the scope and payment requirements may need to be reviewed again.

Before submitting project files, review what AES will need from you.

What Should the Quote Explain Before Payment?

The quote should identify the service being purchased clearly enough for the client to understand what the payment covers.

Review the proposal for information about:

The project and property address
The report type
The calculation scope
The plans included in the review
The compliance forms being prepared
The anticipated turnaround
The revision policy
Plan-check correction support
Expedited scheduling when applicable
Services or third-party costs that are not included
The payment amount
The payment deadline

A clearly defined scope can prevent misunderstandings after work begins.

For example, a quote for a new residential report may not automatically cover a later redesign, an additional structure, repeated window revisions, or an unrelated building-department correction.

Similarly, a quote for a limited commercial lighting analysis may not cover changes to the building envelope, HVAC systems, or service water heating unless those subjects were included.

When Is a Title 24 Project Considered Arranged?

A project may be considered arranged after AES and the client have established the proposed service, project information, price, and next steps.

Before payment, the client should know:

Which property the payment applies to
Which version of the plans will be reviewed
What deliverables are expected
What information is still missing
What payment amount has been authorized
What schedule has been discussed

The AES payment page is intended for clients whose service has already been arranged. It should not replace the initial project discussion or quote process.

Call (626) 365-1518 when the project has not yet been reviewed or when you are unsure which amount applies.

Should You Pay Before Sending the Plans?

The consultant generally needs enough project information to understand the requested service. Sending the current plans before or during the quote process allows AES to evaluate the actual scope.

Plans may reveal issues that are not apparent from a verbal description, including:

A larger conditioned area than expected
Multiple buildings or units
Several roof or ceiling assemblies
Extensive glazing
Multiple HVAC systems
Commercial lighting and control requirements
Mixed existing and proposed construction
An existing report that no longer matches the project
Plan-check corrections requiring additional analysis

A quote based on the current plans is generally more useful than one based on incomplete project information.

The client should confirm the scope and payment instructions before sending an amount based on an assumption.

When Do You Pay for a Residential Title 24 Report?

Payment timing for a residential project should follow the terms provided for that specific assignment.

Residential projects may include:

New single-family homes
New multifamily buildings
Detached ADUs
Attached ADUs
Garage conversions
Room additions
Second-story additions
Major remodels
Window and envelope alterations
HVAC-related permit projects

A residential quote may depend on:

Conditioned floor area
Building orientation
Wall, roof, ceiling, and floor assemblies
Window sizes and performance
Heating and cooling equipment
Duct location
Ventilation
Water-heating equipment
Plan completeness
Requested turnaround

Once AES has reviewed the project and issued payment instructions, follow the stated terms.

When Do You Pay for an ADU Title 24 Report?

An ADU report should be quoted according to whether the unit is detached, attached, or converted from existing space.

The scope may depend on:

ADU size
Existing or new conditioned space
Window area and performance
Wall and roof construction
HVAC system type
Ducted or ductless equipment
Ventilation
Water heating
Existing-building conditions

Payment should follow the ADU project quote rather than a general price intended for another type of residential work.

For an accurate review, provide:

ADU floor plan
Exterior elevations
Building sections
Roof plan
Window and door schedule
Insulation details
HVAC specifications
Ventilation information
Water-heating details

Visit the ADU Title 24 page for additional information.

When Do You Pay for a Commercial Title 24 Report?

Commercial projects should also follow the payment terms established for the individual assignment.

Commercial work may include:

New nonresidential buildings
Office tenant improvements
Retail build-outs
Restaurant improvements
Warehouse alterations
Mixed-use projects
Commercial HVAC replacements
Interior lighting alterations
Exterior lighting projects
Multifamily common-area improvements

A commercial quote may require review of:

Architectural plans
Building-envelope details
Mechanical plans
HVAC equipment schedules
Ventilation information
Service water-heating information
Electrical plans
Lighting fixture schedules
Lighting-control plans

The payment amount and timing should correspond to the complete commercial scope.

A quote for a lighting-only project should not automatically be treated as payment for envelope, mechanical, or water-heating calculations unless those services are specifically included.

For related assistance, review Title 24 compliance services and Title 24 energy analysis.

Do You Pay Separately for Energy Calculations?

The relationship between the report fee and energy-calculation work should be explained in the quote.

Energy calculations may support the compliance forms by evaluating:

Building geometry
Conditioned floor area
Building orientation
Wall and roof assemblies
Insulation
Windows and exterior doors
HVAC equipment
Duct locations
Ventilation
Water heating
Commercial lighting power
Lighting controls

Before paying, confirm whether the quoted amount includes the applicable calculations and forms or covers only a limited consulting service.

Visit the Title 24 energy calculations page for more information about the analysis.

When Do You Pay for a Revision?

A revision may fall within the original scope or require additional authorization and payment. The answer depends on the written agreement and the extent of the design change.

Revisions may be needed when the project changes:

Conditioned floor area
Building geometry
Window sizes or performance values
Wall or roof assemblies
Insulation values
HVAC equipment
Duct locations
Ventilation systems
Water-heating equipment
Commercial lighting fixtures
Lighting controls
The overall permit scope

A small clarification may require less work than a major redesign.

Before submitting payment for a revision:

Send the latest plan set
Provide the previous report
Explain what changed
Identify the requested completion date
Request confirmation of the revision scope
Confirm the amount and payment instructions

Do not assume that unlimited revisions are covered by the initial payment.

When Do You Pay for Plan-Check Correction Support?

Correction support may be included in the original project, limited by the agreed scope, or quoted separately.

Building-department comments may involve:

Missing compliance forms
Differences between the report and plans
Incomplete window information
Missing insulation details
Mechanical-equipment discrepancies
Ventilation questions
Water-heating information
Commercial lighting power
Lighting controls
Outdated calculations

Before paying for correction work, submit:

The complete correction notice
The latest architectural plans
Current mechanical and electrical plans
The previously submitted report
Updated product specifications
A written summary of revisions already made

AES can then determine what work is required and whether the correction falls within an existing agreement or requires a separate quote.

When Do You Pay for Expedited Service?

Expedited or priority scheduling should not be assumed to be part of a standard project fee.

When expedited service is available, the quote or invoice should explain:

The priority service being requested
The applicable project scope
The required documents
The requested completion date
The additional fee when applicable
The payment timing

A fast turnaround still requires complete and coordinated project information.

Missing window specifications, insulation details, HVAC equipment, ventilation, water heating, lighting, or controls may prevent the project from being completed by the requested date.

Contact AES before making a payment based on an assumed expedited schedule.

What Happens if the Scope Changes After Payment?

The original payment applies to the scope that was quoted and authorized.

Additional review may be needed when:

The building becomes larger
An additional structure is added
The occupancy changes
A remodel becomes an addition
An ADU design changes substantially
Several new HVAC systems are introduced
The window design changes significantly
The commercial lighting scope expands
The permit jurisdiction requests different documentation
The project is redesigned after calculations are completed

AES should receive the revised plans before the client assumes the previous payment covers the new work.

The revised scope may require:

An updated quote
Additional payment approval
A revised schedule
New or updated calculations
New compliance forms

Notify AES promptly when the design changes.

Should You Pay Third-Party Charges Through AES?

Do not assume that every fee connected to a permit or energy-compliance project should be paid through the AES payment page.

Separate costs may include:

Building-permit fees
Plan-check fees
Government processing charges
HERS field-verification fees
Diagnostic testing
Third-party registrations
Outside consultant charges
Architectural or engineering fees
Contractor labor and materials

The AES payment page should be used for the AES service that has been arranged.

Confirm any unfamiliar charge before paying it.

Does Payment Guarantee Permit Approval?

Payment for a Title 24 report does not guarantee approval of the complete building-permit application.

The building department may review:

Zoning
Architectural plans
Structural engineering
Fire and life safety
Accessibility
Mechanical plans
Electrical plans
Plumbing plans
CALGreen requirements
Energy-compliance documentation
Other jurisdiction-specific requirements

The Title 24 report supports the energy-compliance portion of the permit package. It does not control the building department’s complete review or the work prepared by other professionals.

The project team remains responsible for submitting a coordinated permit package and responding to applicable comments.

How Do You Make an AES Payment?

When the service and payment amount have been arranged, use the AES payment page.

Before completing the payment, verify:

The client name
The project address
The approved amount
The service being paid for
The applicable invoice or quote
Any project reference information requested by AES

Keep a record of the payment confirmation for your project files.

When you are unsure which amount to submit, call (626) 365-1518 before completing the transaction.

Common Payment Mistakes to Avoid

Avoid the following mistakes:

Paying before confirming the project scope
Using a quote prepared for a different property
Assuming an old quote applies to revised plans
Paying for a standard project while expecting expedited service
Assuming unlimited revisions are included
Assuming plan-check corrections are included
Paying an amount that has not been confirmed
Leaving the project address out of the payment information
Assuming third-party fees are payable through AES
Believing payment guarantees permit approval

A brief call or written confirmation can prevent the payment from being associated with the wrong project or service.

Questions to Ask Before Paying

Ask AES:

What service does this payment cover?
Does the quote include energy calculations?
Which compliance forms are included?
Which plan version will be reviewed?
Is payment due now?
Are revisions included?
Are plan-check corrections included?
Is expedited service included?
Are third-party charges included?
What happens if the design changes?
What information is still needed?
What is the anticipated schedule?

The answers should be consistent with the written quote or invoice.
