Title 24 Compliance Documentation Requirements — What Must Be Submitted for Permit Approval
Understanding Title 24 compliance documentation requirements is essential before submitting plans to any California building department. Energy compliance is not just about running calculations—it is about producing the correct certificates, forms, and supporting documentation required by the California Energy Code.
Whether you are building a new home, completing an addition, designing a multi-family development, or managing a commercial tenant improvement, your permit package must include complete and properly prepared energy compliance documentation. Missing forms, outdated software output, or mismatched specifications can lead to plan-check rejection and costly delays.

What Are Title 24 Compliance Documentation Requirements?
Title 24 compliance documentation requirements refer to the official forms and supporting calculations that demonstrate a project meets California’s Building Energy Efficiency Standards (Title 24, Part 6).
These typically include:
- Certificates of Compliance (CF1R or NRCC forms depending on project type)
- Mandatory measures documentation
- Performance model summaries (if using performance method)
- Lighting compliance forms (commercial projects)
- Solar PV documentation (when required)
All documentation must be generated using CEC-approved software when performance modeling is required.
Residential Title 24 Documentation Requirements
For residential projects, Title 24 compliance documentation requirements commonly include:
- CF1R forms generated by approved modeling software
- Envelope specifications (insulation, glazing values)
- HVAC efficiency documentation
- Duct leakage verification assumptions
- Whole-house ventilation compliance details
- Solar photovoltaic documentation for applicable new construction
These documents must align exactly with the architectural and mechanical plans submitted for permit.
Commercial Title 24 Documentation Requirements
For nonresidential projects, Title 24 compliance documentation requirements may include:
- NRCC forms for envelope and mechanical compliance
- Lighting power density calculations
- Lighting control documentation
- Daylighting zone compliance forms
- Mechanical system efficiency documentation
- Economizer compliance details
Commercial projects require careful coordination between mechanical, electrical, and architectural sheets to ensure consistency.
Prescriptive vs. Performance Documentation
The Title 24 compliance documentation requirements differ depending on the chosen compliance pathway.
Prescriptive Method:
Requires documentation confirming that all components meet minimum code standards.
Performance Method:
Requires energy modeling output demonstrating that the proposed design performs at or above baseline requirements.
Performance documentation includes additional summary reports and compliance certificates generated by approved software.
Common Documentation Mistakes That Lead to Rejection
Failure to meet Title 24 compliance documentation requirements can result in correction notices. Common issues include:
- Window U-factor values on forms not matching plan schedules
- Incorrect HVAC efficiency entries
- Outdated software versions used for modeling
- Failure to update documentation after plan revisions
- Missing lighting control documentation (commercial)
- Incomplete mandatory measures forms
Accuracy and coordination are critical to avoid delays.
Documentation Required at Inspection
Compliance does not end at plan check. Title 24 compliance documentation requirements also extend to construction and inspection phases.
Required field documentation may include:
- Certificates of Installation (CF2R forms)
- HERS verification documentation (CF3R forms)
- Confirmation that installed systems match approved documentation
If installed equipment differs from the approved forms, documentation must be revised before final approval.
How to Ensure Complete Documentation Before Submission
To meet Title 24 compliance documentation requirements efficiently:
- Coordinate energy modeling during design development
- Finalize window and HVAC selections before permit submission
- Verify that compliance forms match the latest plan revision
- Use current CEC-approved software versions
- Review documentation for internal consistency before submission
Professional review helps ensure your permit package is complete the first time.
