The Energy Code Compliance (ECC) Program will be administered by ECC-Providers that must be approved by the CEC to conduct the duties specified in the 2025 Energy Code, which include training and oversight of ECC-Raters and operation of a residential data registry. All ECC-Provider responsibilities are given in Section 10-103.3 of the 2025 Energy Code and in the 2025 Reference Appendices.
ECC-Provider applications may be electronically filed to CEC docket log 25-BSTD-01.
Prospective ECC-Providers are encouraged to review the 2025 Energy Code Compliance Provider Application Guide. The guide addresses application preparation, submission, evaluation, and approval.
