How Much Does a Title 24 Report Cost?

Call (626) 365-1518 | Alternative Energy Systems

The cost of energy-compliance documentation is an important consideration when planning a California construction project. How Much Does a Title 24 Report Cost is best answered after reviewing the project type, size, scope, available plans, building systems, requested turnaround, and whether corrections or revisions are involved.

There is no single price that accurately applies to every project. A straightforward residential addition with a coordinated plan set will not require the same level of analysis as a custom home, multifamily development, restaurant improvement, commercial lighting project, or building with several mechanical systems.

Alternative Energy Systems provides project-specific quotes after reviewing enough information to understand the work involved. AES considers the proposed construction, quality of the submitted documents, energy-related systems, anticipated schedule, and any previous reports or plan-check comments that must be evaluated.

AES brings more than 30 years of California energy-compliance experience to residential, multifamily, mixed-use, and commercial permit projects. Call (626) 365-1518 to describe your project, submit the available plans, and request a quote based on the actual scope.

How Much Does a Title 24 Report Cost for a Specific Project?

The cost is determined by the amount of professional review, calculation, documentation, and coordination the project requires.

Pricing may be influenced by:

Residential or commercial property type
New construction, addition, conversion, or alteration
Building size and configuration
Complexity of the building envelope
Number of windows, doors, and conditioned spaces
Heating and cooling systems
Duct and ventilation design
Water-heating systems
Commercial lighting and controls
Completeness of the submitted plans
Requested turnaround
Existing plan-check corrections
Changes to a previously completed report

A project-specific quote is more reliable than a generic price because it reflects the actual plans and expected workload.

Before requesting pricing, gather the current plan set and provide a clear description of the proposed work. AES can then determine what information is available, what remains missing, and what services may be needed.

Why Is There No Single Flat Price for Every Title 24 Report?

Title 24 reports are based on individual building designs. Two projects with similar square footage may still require different amounts of work.

One project may have a simple rectangular layout, complete window specifications, a single HVAC system, and coordinated drawings. Another project of the same size may include multiple roof conditions, extensive glazing, several mechanical systems, incomplete equipment schedules, and revisions from a previous permit submittal.

The following differences can affect pricing:

One-story versus multistory construction
Simple versus complex building geometry
Standard versus custom window configurations
One HVAC system versus several systems
Ducted versus ductless equipment
Complete versus incomplete plans
New calculations versus revisions to previous work
Residential versus nonresidential documentation
Standard scheduling versus expedited service

A responsible quote should therefore be based on the project documents rather than an unsupported estimate that ignores the design.

What Is Included When Pricing a Title 24 Report?

The exact service should be confirmed in the project quote, but report preparation generally involves more than generating a few forms.

The work may include:

Reviewing the proposed project scope
Examining the current construction plans
Identifying missing energy-related information
Reviewing windows, insulation, roofing, and other envelope details
Reviewing HVAC, ducts, ventilation, and water heating
Reviewing commercial lighting and controls when applicable
Completing the applicable energy analysis
Preparing project-specific compliance forms
Explaining measures that must be coordinated with the plans

The report should reflect the actual project. It should not be based on a generic building description that overlooks the proposed construction.

Ask what is included before authorizing the work, particularly when comparing quotes from different providers.

What Project Details Affect the Cost?

Several project characteristics can affect the time and analysis required to prepare the documentation.

Project Type

A residential and commercial project may involve different forms, systems, design documents, and coordination requirements.

Project types may include:

New single-family homes
New multifamily buildings
Accessory dwelling units
Garage conversions
Room additions
Residential remodels
Commercial tenant improvements
Retail and restaurant build-outs
Office improvements
Commercial HVAC alterations
Lighting and lighting-control projects
New nonresidential buildings

The provider must understand the actual occupancy and scope before determining the work involved.

Building Size

Building size may affect the amount of information that must be reviewed and entered into the analysis. However, square footage is only one pricing factor.

A smaller building with complex geometry, extensive windows, several roof conditions, or incomplete plans may require more coordination than a larger but straightforward project.

Building Geometry

The shape and configuration of the building may affect the analysis.

Complexity can increase when the project has:

Several building wings
Multiple stories
Numerous exterior wall conditions
Several roof types
Vaulted ceilings
Raised floors
Mixed conditioned and unconditioned areas
Attached existing and proposed construction

Number of Building Systems

A project with one clearly specified mechanical system may require less coordination than a building with several systems serving different areas.

The same principle can apply to water heating, ventilation, lighting, and controls.

How Plan Quality Affects the Cost

Complete, coordinated plans allow the consultant to understand the project with fewer requests for clarification.

A useful plan set may include:

Cover sheet and project data
Site plan
Existing and proposed floor plans
Exterior elevations
Building sections
Roof plans
Wall and roof details
Window and door schedules
Mechanical plans
Electrical and lighting plans
Applicable equipment schedules

Additional review may be needed when the plans contain:

Conflicting floor areas
Unlabeled existing and proposed construction
Missing dimensions
Window schedules that do not match the elevations
Undefined insulation assemblies
Incomplete HVAC information
Missing lighting controls
Several plan versions with no current file identified

Incomplete plans do not always prevent the process from starting, but additional coordination can affect the project scope, schedule, and price.

How Much Does a Residential Title 24 Report Cost?

Residential pricing depends on the design and information available rather than the word “residential” alone.

A residential report may be prepared for:

A new home
An ADU
A garage conversion
A room addition
A second-story addition
A major remodel
A multifamily improvement
A window or envelope alteration
An HVAC-related permit project

Residential calculations may consider:

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

The more clearly these items are documented, the easier it is to determine the work required and provide a useful quote.

How Much Does a Title 24 Report Cost for an ADU?

ADU pricing depends on whether the unit is detached, attached, or created through a garage conversion. The size of the ADU is important, but the relationship between existing and proposed construction can also affect the review.

A quote may consider:

Attached or detached construction
New or converted conditioned space
Number and performance of windows
Wall and roof assemblies
Heating and cooling equipment
Ducted or ductless design
Ventilation
Water-heating equipment
Completeness of the ADU plans

A detached ADU with a complete and coordinated plan set may involve a different process from a garage conversion where existing conditions are unclear.

To request a quote, provide:

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

Visit the ADU Title 24 page for additional project information.

How Much Does a Report Cost for an Addition?

Addition pricing depends on the size of the new conditioned space and the amount of coordination required between the existing residence and proposed work.

The consultant may need to review:

Existing floor area
New conditioned floor area
Removed and proposed walls
New windows and doors
Roof and ceiling assemblies
HVAC extensions or new equipment
Changes to ventilation
Water-heating changes when applicable

An addition with complete plans and final product information may be easier to quote than one where the design remains unsettled.

How Much Does a Report Cost for a Remodel?

Remodel pricing depends on which energy-related components are being altered.

A remodel may involve:

Replacement windows
Altered exterior walls
New insulation
Roofing changes
HVAC replacement
Duct changes
Ventilation changes
Water-heating replacement
Expanded conditioned space

A cosmetic interior remodel may have a different energy-compliance scope from a project that changes the exterior envelope and mechanical systems.

Describe the complete proposed work when requesting pricing. Omitting major alterations can result in a quote that does not reflect the actual project.

How Much Does a Commercial Title 24 Report Cost?

Commercial pricing depends on the occupancy, project size, systems involved, plan quality, and whether the work affects the building envelope, mechanical equipment, lighting, or 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 alterations
Exterior lighting projects
Multifamily common-area improvements

Commercial documentation 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

A commercial quote should be based on the complete scope rather than only the tenant-space square footage.

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

How Commercial Lighting Affects the Cost

Commercial lighting projects may require review of fixture power, quantities, room uses, and control strategies.

The consultant may need:

Lighting floor plans
Fixture schedules
Fixture wattage
Fixture quantities
Room or space classifications
Occupancy sensors
Automatic shutoff controls
Daylighting controls
Exterior lighting information

A small tenant space with a complete fixture schedule may involve a different level of work from a larger project with several lighting zones and incomplete control information.

How Mechanical Systems Affect the Cost

Mechanical complexity can affect the amount of documentation and coordination required.

Pricing may be influenced by:

Number of HVAC systems
Equipment types
Heating and cooling efficiencies
System capacities
Ducted or ductless design
Duct locations
Ventilation systems
Control strategies
Existing systems that remain
New systems serving additions or tenant spaces

Submit mechanical plans and equipment schedules when available. A quote based only on a general statement such as “new HVAC” may not account for the full system design.

Does Turnaround Time Affect the Price?

The requested schedule may affect the quote, particularly when expedited review is requested.

Before asking for urgent completion, provide:

The current plan set
Required specifications
The desired completion date
The planned permit-submittal date
Any existing correction deadline

An expedited request may still be delayed when essential project information is missing. A consultant cannot complete an accurate report without enough information to understand the design.

Contact AES early rather than waiting until the planned submittal date. Early review gives the project team more time to resolve incomplete windows, insulation, equipment, lighting, and other energy-related details.

Do Revisions Cost Extra?

Revision requirements depend on what changed and the terms of the original service agreement. Ask how revisions will be handled before authorizing the project.

A minor clarification may involve a different amount of work from a major redesign.

Changes that may require review include:

Revised conditioned floor area
New or resized windows
Different window performance values
Changed insulation assemblies
Revised roofing characteristics
Different HVAC equipment
Relocated ductwork
Changed ventilation systems
Different water-heating equipment
Revised commercial lighting fixtures
Changed lighting controls
Expanded project scope

When requesting a revision quote, provide the latest plans and a written summary of everything that changed.

Do not submit an outdated report with revised plans without first determining whether the calculations and forms remain consistent with the project.

How Much Does It Cost to Address Plan-Check Corrections?

The cost of correction support depends on the nature of the building-department comments and whether the original report or design must be revised.

Correction comments may involve:

Missing compliance forms
Differences between the report and plans
Incomplete window specifications
Missing insulation details
Mechanical-equipment discrepancies
Ventilation questions
Commercial lighting information
Lighting-control requirements
Outdated calculations

Submit the complete correction notice rather than one isolated comment.

AES may also need:

The latest architectural plan set
Current mechanical and electrical plans
The previously submitted report
Updated product specifications
A summary of revisions already made

The complete package allows AES to understand whether the correction requires a simple clarification or broader changes to the analysis.

Call (626) 365-1518 to request a review of energy-related plan-check comments.

Can a Previous Report Lower the Cost?

A previous report may provide useful background, but it does not automatically reduce the work required.

AES must determine:

Whether the previous report matches the current property
Whether the plans used for that report are available
Whether the design has changed
Whether the previous equipment remains specified
Whether the current permit scope is different
Whether updated forms or calculations are required

Submit:

The previous report
The old plan set
The current plan set
A written change summary
Updated specifications
Existing correction comments

A report prepared for an earlier design should not be reused without reviewing it against the current project.

What Information Is Needed for an Accurate Quote?

A clear quote begins with a clear submission.

Provide:

Project address
Permit jurisdiction
Residential or commercial property type
Description of the proposed work
Current architectural plans
Approximate project size
Window and door information
Insulation and roof details
HVAC and duct information
Ventilation details
Water-heating information
Commercial lighting information when applicable
Requested turnaround
Previous reports
Plan-check correction notices

AES can review partial information and explain what is still needed. However, a quote based on a complete plan set is generally more useful than one based on an incomplete verbal description.

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

Can You Request Pricing With Preliminary Plans?

Preliminary plans can be submitted for an initial review. AES may be able to identify the likely project scope and provide guidance about the information needed to move forward.

However, pricing may need to be revisited if the project changes substantially.

Preliminary items that may later affect the scope include:

Final conditioned floor area
Window sizes and quantities
Insulation assemblies
Roof design
HVAC systems
Ventilation
Water heating
Commercial lighting
Lighting controls

Tell AES which decisions remain pending. This is more useful than presenting preliminary information as though it has been finalized.

What Should You Ask Before Accepting a Quote?

Review the proposal carefully so you understand what service is being provided.

Ask:

What project scope is included?
Which documents were used to prepare the quote?
What information is still missing?
What deliverables are included?
How is turnaround determined?
How are design changes handled?
How are plan-check corrections handled?
Are future revisions included or quoted separately?
What happens if the project scope expands?
When is payment required?

A clearly defined quote can help prevent misunderstandings when the plans change or additional work is requested.

Should You Choose the Lowest-Priced Report?

Price is important, but it should not be the only consideration.

An unusually low quote may not be comparable when another provider includes a more complete plan review, project coordination, or revision support.

Before selecting a consultant, consider:

California energy-compliance experience
Experience with your project type
Quality of the plan-review process
Communication about missing information
Ability to explain the compliance measures
Revision procedures
Correction-response support
Clarity of the proposed scope

A report that does not reflect the current plans may create additional costs through revisions, resubmittals, or construction changes.

No provider should guarantee complete permit approval. The report supports the energy-compliance portion of the permit application, but the full project remains subject to building-department review.

Can a Title 24 Report Help Avoid Other Project Costs?

A properly timed report can help identify energy-related issues before plans are submitted or products are ordered.

Early review may reveal:

Incomplete window specifications
Unclear insulation assemblies
Conflicting floor areas
Undecided HVAC equipment
Missing duct information
Incomplete ventilation details
Unresolved water-heating selections
Commercial lighting conflicts

Identifying these issues during design may be easier than addressing them after permit submittal or construction.

The report cannot eliminate every correction or project expense. It can, however, provide a structured review of energy-related design information before those decisions are carried further into the project.
