Existing law establishes the California Building Standards Commission and the State Fire Marshal’s duties regarding building standards, including fire safety for lithium-based battery systems. This bill requires the commission and the State Fire Marshal to review and consider the latest edition of NFPA 855 for incorporation into the California Building Standards Code after July 1, 2026. It also mandates that applications for energy storage system certification submitted to the Energy Commission and local jurisdictions include a certification that the facility complies with NFPA 855 standards. Additionally, applicants must meet with the local fire department before submitting the application, and local jurisdictions must require that systems be built and maintained in accordance with NFPA 855, including inspections by the fire department before operations begin.
