The code applies to all buildings that are heated and/or mechanically cooled and are defined under the Uniform Building Code as A, B, E, H, N, R, or S occupancies, except registered historical buildings. Additions and renovations are also covered by the code. Institutional building's which include hospitals and prisons are not covered.

For residential low-rise buildings the current code provision include compliance credits for high performance ducts and building envelope features. The size of credit depends on the action taken. For example simply designing ducts to Air Conditioner Contractor's Association guidelines or properly sealing duct joints provided lower levels of credit than having the HVAC system tested for duct leaks. To take credit for these measures the installer and inspector must be trained and certified.

Local governmental agencies can modify the state energy code to be more stringent when documentation is provided to the California Energy Commission.
