The rule, added to the local Building Code as Section 450.2, applies to buildings four or more stories tall (up to 75 feet) and sets NFPA-based design standards.
Section 450.1. Applicability.

Full Breakdown
2 to the 2025 California Building Code. Section 202 defines a "mid-rise structure" as any new building at or above four stories above the lowest point of fire department access, while being 75 feet or less in height to the finished floor of the highest occupied level. 1 makes the sprinkler and life-safety package apply to all newly constructed mid-rise structures and to existing mid-rise structures undergoing substantial renovation requiring the building to be vacated; parking garages, towers, and steeples not used for continuous human occupancy are exempted.
2 requires the automatic fire sprinkler system to be designed and installed under the adopted edition of NFPA 13, with an electronically supervised shutoff valve and water-flow alarm device on every floor. 5-inch hose valves at every floor level in every stair enclosure that penetrates the roof, designed, installed, and tested to NFPA 14. The same article separately requires a fully addressable fire alarm system (Sec. 4), an emergency voice/alarm communications system built to NFPA 72 (Sec. 41), and stairway doors capable of unlocking simultaneously on a fire-panel signal or loss of power (Sec.
2). 2 additionally requires 18 inches of clearance around any concealed sprinkler riser and a dedicated 30-by-80-inch access door with exterior signage identifying the riser and alarm room.
Violations & Fines
Mid-rise construction that omits the required NFPA 13 sprinkler system, Class I standpipe, or fire alarm package fails building plan review and cannot receive occupancy release under the city's coordination procedure (Sec. 6.32.2); the building official withholds final approval until the fire-protection systems are installed, inspected, and verified compliant.
