Title 24 Plan Check Comments Explained — What Reviewers Mean and How to Respond Correctly
If you’ve landed here looking for Title 24 plan check comments explained, you’re probably staring at a correction list that feels half technical, half cryptic. That’s normal. Building departments often write Title 24 comments in short, checklist-style language because they’re reviewing hundreds of files and need quick, verifiable answers. But a short comment can hide a very specific requirement—one that affects whether your permit is approved, held, or rejected.
In California, Title 24 compliance is part of the building code, and many permits cannot be issued until the energy documentation is both compliant and consistent with the plan set. Plan check comments usually mean one of three things: (1) the reviewer sees a mismatch, (2) the reviewer needs missing information to verify compliance, or (3) the project was classified under the wrong compliance pathway.
This page breaks down common Title 24 plan-check comments, what they actually mean, and how to respond in a way that gets approvals faster and reduces repeat corrections. If you need targeted help responding to a correction list, call (626) 365-1518.
Why Title 24 Plan Check Comments Happen
Before we translate comments, it helps to understand the reviewer’s job. Plan checkers are not trying to redesign your project—they are verifying that regulated energy components match the documentation and the code pathway. That verification is built around “alignment.”
The most common reasons Title 24 plan check comments appear are:
- The energy report was built from an older plan set or outdated schedule
- Key values (windows, insulation, HVAC, lighting) don’t match between sheets and forms
- The reviewer can’t find required information in the plans (missing schedules or notes)
- The compliance pathway doesn’t match the project scope (addition vs. remodel vs. TI)
When you approach comments as “alignment checks,” they become easier to fix.
How to Read a Title 24 Comment the Right Way
When you see a line like “Energy forms do not match plans,” the correct response is not “please approve anyway.” The correct response is to identify exactly which values differ and revise the package so the plan set and compliance documents agree.
A good response typically includes:
- A corrected energy report (regenerated forms, not just annotations)
- Updated plan schedules or notes (if the plans were the source of confusion)
- A clear resubmittal package that addresses each comment directly
Now let’s translate common comments.
Common Title 24 Plan Check Comments Explained
Below are frequent city comments and what they usually mean in practice.
Comment: “Energy forms do not match plans.”
Meaning: One or more regulated values on the compliance forms conflict with the plan set. The reviewer may not specify which ones.
How to respond: Cross-check windows (U-factor/SHGC), insulation R-values, HVAC type/efficiency, and (commercial) lighting. Update the model and regenerate forms to match the latest plan set.
Comment: “Provide updated Title 24 documentation to reflect revised plans.”
Meaning: The plan set revision date is newer than the energy report.
How to respond: Confirm the latest plan revision date, update modeling inputs accordingly, regenerate forms, and resubmit only the current plan set and current forms.
Comment: “Clarify window U-factor and SHGC values.”
Meaning: The window schedule is missing performance values, uses placeholders, or conflicts with the report.
How to respond: Provide a clear window schedule with U-factor/SHGC and ensure the energy forms match exactly. If glazing sizes changed, update the model.
Comment: “Insulation values inconsistent across plans.”
Meaning: Different sheets show different R-values (or some assemblies are not specified).
How to respond: Standardize insulation callouts across details, sections, and notes. Update the model and regenerate the forms if insulation inputs change.
Comment: “Provide mechanical system efficiency and system type.”
Meaning: The mechanical schedule is missing efficiency data (SEER2/EER/AFUE/HSPF2, etc.) or system type is unclear.
How to respond: Update mechanical schedules/notes and ensure the energy report lists the same system type and efficiencies.
Comment: “Ventilation compliance method unclear.”
Meaning: The plans do not show how ventilation requirements are being met, or the report assumptions are unclear.
How to respond: Clarify ventilation strategy in mechanical notes and ensure the modeled approach matches the plan notes.
Comment: “Incorrect compliance pathway/method.”
Meaning: The reviewer believes the project should be modeled under a different scope or occupancy pathway (e.g., addition vs. new construction, residential vs. nonresidential).
How to respond: Reconfirm project scope, update the compliance method if needed, rebuild/regenerate forms under the correct pathway, and resubmit cleanly.
Comment: “Provide lighting compliance documentation and controls.” (Commercial/TI)
Meaning: The electrical set lacks clear documentation for lighting power density (LPD), fixture schedules, control sequences, or daylighting zones.
How to respond: Provide lighting schedules, LPD calculations, space type labeling, and control diagrams consistent with the compliance documents.
Comment: “Daylighting controls required—show zones and controls.” (Commercial)
Meaning: Based on glazing/skylights and space type, the reviewer expects daylight-responsive controls that are not documented.
How to respond: Identify daylighting zones on plans, specify control devices and sequences, and align with compliance documentation.
Comment: “Provide certificates in the plan set / include compliance forms in submittal.”
Meaning: The reviewer cannot locate required certificates in the uploaded file set or plan sheets.
How to respond: Include the correct compliance forms as part of the submittal package and label files clearly. Some jurisdictions prefer the forms embedded in plan sets—follow local instructions.
What Reviewers Usually Check First
If you want a practical way to interpret comments quickly, here is what many reviewers verify first because it’s fast and objective:
- Plan set revision date vs. report generation date
- Window schedule performance values vs. energy form values
- Insulation callouts across the envelope
- Mechanical schedule (system type and efficiency) vs. compliance documentation
- Commercial lighting schedules and controls (if applicable)
When these items align, many Title 24 comments disappear.
How to Respond to Title 24 Plan Check Comments Without Triggering More Corrections
A common mistake is responding with partial fixes. For example: updating the energy report but leaving the plan schedule inconsistent, or revising a plan note but not regenerating the compliance forms. The best practice is “one coordinated update.”
To reduce repeat corrections:
- Use one plan set only (one revision date across all sheets)
- Update schedules before regenerating compliance forms
- Regenerate the full compliance package after any regulated changes
- Remove conflicting notes (especially insulation and ventilation)
- Answer each reviewer comment directly in the resubmittal set
This is the simplest way to move from “comments issued” to “approved.”

Frequently Asked Questions About Title 24 Plan Check Comments Explained
1. What are Title 24 plan check comments?
They are reviewer notes indicating mismatches, missing information, or pathway issues in energy compliance documentation needed for permit approval.
2. Does receiving comments mean the project failed compliance?
Not necessarily. Many comments involve documentation alignment and clarification rather than a true performance failure.
3. What is the most common plan check comment?
“Energy forms do not match plans” is one of the most common because mismatches are easy to spot.
4. Why do cities say the energy report doesn’t match plans?
Because values like windows, insulation, HVAC, or lighting differ between the report and the drawings.
5. Can a new plan revision trigger comments even if the design is similar?
Yes. Even minor revisions can change regulated inputs that must match the energy report.
6. Do window schedules cause many Title 24 comments?
Yes. Missing or inconsistent U-factor/SHGC values are a frequent cause.
7. Why do insulation notes trigger comments?
Because conflicting R-values across sheets make compliance unverifiable.
8. What does “provide mechanical efficiency” mean?
It means the mechanical schedule must show equipment efficiencies and the report must match those values.
9. What does “ventilation method unclear” mean?
It means the plans and report do not clearly show how ventilation requirements are being met.
10. What does “incorrect compliance pathway” mean?
It means the project scope or occupancy appears to be modeled under the wrong method (addition vs. remodel, residential vs. nonresidential, etc.).
11. Do commercial projects receive different Title 24 comments?
Often yes. Commercial comments frequently involve lighting power density, controls, and space type labeling.
12. What does “provide lighting controls documentation” mean?
It means the electrical plans must show control devices, sequences, and zoning consistent with Title 24 requirements.
13. What are daylighting zone comments about?
They relate to required daylight-responsive controls based on glazing/skylights and space type.
14. Should I regenerate forms after making corrections?
Yes. Regenerating a clean compliance package is often required for approval.
15. Can partial fixes lead to more comments?
Yes. Fixing one mismatch while leaving others unresolved often triggers repeat corrections.
16. Do reviewers check plan dates against report dates?
Often yes. A report built from older plans is a common rejection trigger.
17. How can I reduce back-and-forth with plan checkers?
Submit a coordinated package where schedules, notes, and compliance forms match exactly and every comment is addressed directly.
18. What should I include in a resubmittal?
The corrected forms, updated plans/schedules (if needed), and a clear response to each city comment.
19. Can you explain my specific city comments?
Yes, with the correction list and your plan set we can translate and fix the underlying mismatches.
