(a) Minimum number of detectors. No less than one approved smoke detector shall be provided on the highest habitable level and on each floor, story or level below, including basements or cellars.

Full Breakdown
Under Section 1221.1 of the city's building code amendments (Code § 15.04.030), any one-, two-, or three-family dwelling permitted or substantially altered since the ordinance's adoption must have at least one approved smoke detector on the highest habitable level and on each floor, story, or level below, including basements, plus one per additional 1,200 square feet on larger floors. Section 1221.2 requires a detector outside each separate sleeping area and at the bottom of any stairway with a door at the top, bars placement in kitchens, and mandates ceiling mounting. Section 1221.3 requires permanent AC wiring ahead of any switches, with all required detectors interconnected so one activating trips them all, and UL- or FM-listed devices. Owners must maintain the system; the bureau of fire prevention and department of inspections enforce it.
