Historical buildings are subject to the authority of the California State Historical Building Safety Board. When new or replacement features are added to historical buildings they should comply with Standards, but the local building department and the Historical Building Safety Board would need to make the final determination (see the excerpt from the RCM below).
CODES, CALIFORNIA HISTORICAL BUILDING CODE is the California Historical Building Code, California Code of Regulations, Title 24, Part 8 and Part 2 (Chapter 34).
RCM 1.5.4 - Historical Buildings
Exception 1 to §100.0(a) states that qualified historic buildings, as regulated in the California Historical Building Code (Title 24, Part 8) or California Building Code, Title 24, Part 2, Volume I, Chapter 34, Division II are not covered by the Building Energy Efficiency Standards. Section 140.6(a)3 clarifies that lighting systems in qualified historic buildings are exempt from the lighting power allowances only if they consist solely of historical lighting components or replicas of historical lighting components. If lighting systems in qualified historic buildings contain some historical lighting components or replicas of historical components, combined with other lighting components, only those historical or historical replica components are exempt. All other lighting systems in qualified historic buildings must comply with the Building Energy Efficiency Standards.
The California Historical Building Code (CHBC) Section 8-102.1.1 specifies that all nonhistorical additions must comply with the regular code for new construction, including the Building Energy Efficiency Standards. CHBC Section 8-901.5 specifies that when new or replacement mechanical, plumbing, and electrical (including lighting) equipment or appliances are added to historic buildings, they should comply with the Building Energy
Efficiency Standards, including the Appliance Efficiency Regulations.
The California State Historical Building Safety Board has final authority in interpreting the requirements of the CHBC and determining to what extent the requirements of the Building Energy Efficiency Standards apply to new and replacement equipment and other alterations to qualified historic buildings. In enacting the State Historical Building Code legislation, one of the intents of the Legislature was to encourage energy conservation in alterations to historic buildings (Health and Safety Code Section 18951).
