Title 24 Compliance Forms
Title 24 compliance is documented on standardised forms. Which ones a project needs depends on whether it is residential or nonresidential, and on how far along it is — design, installation, or field verification.

Residential forms
Residential compliance runs through three certificate families, each covering a different stage of the project.
- CF1R — Certificate of Compliance. Prepared at design stage from the plans, and the document a building department normally asks for at permit.
- CF2R — Certificate of Installation. Completed by the installing contractor to confirm what was actually built matches what was approved.
- CF3R — Certificate of Verification. Completed by a third-party HERS rater where measures require independent field verification.
Nonresidential forms
Commercial and other nonresidential projects use the NRCC series, with parallel NRCI installation and NRCV verification documents. Scope drives which apply: a lighting-only tenant improvement and a full building shell produce very different sets.
Multi-family buildings have their own document, the LMCC, which covers the low-rise multifamily compliance path.
Registration
Some documents must be registered with an approved data registry rather than simply signed, which is how the state tracks verified measures. Where registration applies it is part of preparing the report, not a separate step for the customer.
Which form do you need?
For most permit submittals on a home, ADU or addition, the answer is a CF1R. ADU reports, residential reports and multi-family reports all include the applicable certificates. Commercial projects are quoted after a scope review.
