2025 Single-Family Energy Code Forms
Official California Energy Commission compliance documents to show compliance with 2025 California
Building Energy Efficiency Standards (Title 24, Part 6 or Energy Code).
These forms are for single-family, townhome and duplex projects. Low-rise (three stories or less)
Multifamily and Mixed-Use must use new LMCC, LMCI and LMCV forms to document compliance starting with
the 2025 Energy Code.
CF1R Forms (Single-Family Certificates of Compliance)
If your project scope includes ECC measures, CF1R documents will need to be completed through a ECC Provider's registry. See the California Energy Commission website for more information on ECC and the ECC program.
CF1R documents are to demonstrate the project design and equipment are compliant with the Energy Code at time of permit application. You can use the Forms Ace tool to determine if your project requires ECC verification.

Forms Ace™
The Forms Ace™ tool helps you figure out which Title 24, Part 6 forms apply to your specific project.
Use this tool before your permit submittal to determine which forms will be required for your Addition,
Alteration or New Construction project — and whether or not your project requires HERS (Home Energy Rating
System) verification.
