Exceptions and notes
Statewide 2025 California Fire Code (Title 24, Part 9) on a 2024 IFC base. Section 1201.1 sends energy storage systems regulated by Section 1207 to NFPA 855, and Chapter 80 lists NFPA 855, 2023 edition. Battery storage provisions also sit in Section 320 as amended. California moved battery storage into new Section 320 (with 2024 IFC Section 320 as base) and added NFPA 855-correlated definitions; permit exemptions for some residential ESS at 105.5.14.
