Local Amendments: Fremont's expanded sprinkler mandate in FMC 15.35.150 (§903.2): all Group A, B, E, F, H, I, M, R, and S-1 occupancies require automatic sprinkler systems regardless of area threshold — eliminating several IFC and CFC area exceptions.

FMC 15.35.100 (§202) defines 'Local Fire Alarm' to require more than one notification appliance on each floor (stricter than NFPA 72). 'Semiconductor Fabrication Facility' definition codified locally to trigger H-occupancy alarm and detection requirements for fab and R&D areas.

Local Amendments: FMC 15.35.160 amends CFC §904 with Fremont-specific language regarding alternative extinguishing systems. Dual enforcement: Fremont Fire Prevention Bureau enforces hood cleaning and suppression under CFC §609/§904.14, while Alameda County Environmental Health enforces under Health and Safety Code §114149.1 — both agencies have independent closure authority.
