This document is intended to assist entities seeking California Energy Commission (CEC) approval to administer the residential Energy Code Compliance (ECC) Program in support of the 2025 Energy Code. If approved, the entity will become an Energy Code Compliance Provider (ECC-Provider) that will provide Energy Code Compliance Rater (ECC-Rater) certification and oversight services. The ECC-Provider will also operate a CEC-approved residential data registry for the production of documents that demonstrate and certify compliance with the Energy Code.
The ECC Program is established in the 2025 Energy Code by "Administrative Procedures for the Energy Code Compliance Program" in the California Code of Regulations (CCR), title 24, part 1, chapter 10, section 10-103.3.
The report identifies and explains ECC-Provider and residential data registry application regulations, then provides guidance for the organization of the respective applications. It identifies updated regulations related to ECC-Provider responsibilities and duties. The report also offers guidance on how an applicant could demonstrate meeting applicable regulations.
This document is supplemented by a checklist for applicants to use while developing an application. For each regulatory item, the checklist summarizes evaluation criteria that CEC staff could use in reviewing the applications. The staff’s review will be considered by the CEC’s executive director, who will recommend to the CEC to approve, limit, or deny each application.
The guidance in this report pertains to "first-time approval of an ECC-Provider" as mentioned in the ECC-Provider Approval section of the ECC Program regulations. An entity's initial ECC-Provider approval, as well as subsequent updated approvals, will rely on submission of a Full Application as detailed in 24 CCR 10-103.3(c)3
