CF2R vs CF3R: What's the Difference?
CF2R vs CF3R: Understanding Title 24 Compliance Forms
The CF2R is a declaration by the trade contractor that they installed the specified energy measure correctly. The CF3R is the independent verification signed by a certified HERS or ECC rater after they have personally tested and inspected the installation.
The Title 24 Compliance Document Chain
To understand CF2R and CF3R forms, you first need to understand how Title 24 documentation flows through a construction project. The CF1R is the compliance report, generated by an energy consultant. The CF2R is the installer certificate, and the CF3R is the verifier certificate.
Why Both Forms Are Required
California's Title 24 compliance system is built on the principle that self-certification alone isn't sufficient for energy measures. The two-step system creates accountability at both the installation and verification levels.
