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 ECC-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.
Where a project installs lighting controls or mechanical systems that have to be functionally tested, it also produces an NRCA — Certificate of Acceptance, completed by a certified acceptance test technician after the system is running. It is the only certificate in the family that reports a test result rather than a description.
Multi-family buildings have their own document, the LMCC, which covers the low-rise multifamily compliance path.
Covered process forms
Equipment the code regulates in its own right — refrigeration, enclosed parking garage ventilation, process boilers, compressed air, elevators and escalators — is documented on a separate pair of certificates rather than inside the mechanical set. The NRCC-PRC is the compliance certificate produced at design stage, and the NRCI-PRC is the installation certificate signed by whoever fitted the equipment.
These are the forms most often missing from an otherwise complete submittal, because the equipment behind them is usually selected by a specialist contractor rather than by the design team assembling the compliance documents.
Reading a form code
Every nonresidential code has three parts: the family (which stage), the discipline (which system) and a suffix saying who may sign it. Title 24 form codes and suffixes explained decodes the whole set, including why an -A form and an -F form mean two very different things at the end of a job.
The installation and verification stages have their own families: NRCI — Certificate of Installation, one per discipline and signed by whoever installed the work, and NRCV — Certificate of Verification, which for 2025 is a single form covering building air leakage.
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.
