CALGreen applies to the planning, design, operation, construction, use, and occupancy of every newly-constructed building or structure on a statewide basis unless otherwise indicated. Additions and alterations to existing buildings which increase the building’s conditioned area, interior volume, or size are also covered by the scope of CALGreen.
CALGreen also specifies requirements for applications regulated by the California Building Standards Commission (BSC), California Energy Commission (CEC), Division of the State Architect (DSA), Department of Public Health (CDPH), Office of Statewide Health Planning and Development (OSHPD), and the Department of Water Resources (DWR). Consistent with other parts of Title 24, the Matrix Adoption Tables at the front of each chapter are to assist the code user to determine which sections or chapters are applicable to buildings under the authority of a specific State agency; however, they are for information only and are not considered regulatory.
