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.
