2025 Low-Rise Multifamily Energy Code Forms
Official California Energy Commission compliance documents you can use to show compliance with 2025
California Building Energy Efficiency Standards (Title 24, Part 6 or Energy Code).
These forms are for low-rise (three stories or less) Multifamily and Mixed-Use projects starting with
the 2025 Energy Code. High-rise (four stories or more) projects should use the Nonresidential forms.
LMCC Forms (Low-rise Multifamily Certificates of Compliance)
The Low-rise Multifamily Certificates of Compliance (LMCC) are to demonstrate the construction documents are compliant with the Energy Code at the time of permit application.
Use the Virtual Compliance Assistant to walk you through form completion and produce the pdf you can take to the Authority Having Jurisdiction for construction permit application.

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.
