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- Uses outdated plans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.

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.
