Full Breakdown
Under Administrative Code § 27-2045, owners of class A and B multiple dwellings and private dwellings occupied by someone other than the owner must provide and install one or more approved, operational smoke detecting devices in each dwelling unit, following section 907.2 of the NYC Building Code or the equivalent 1968 Building Code sections. Owners must periodically replace devices at the end of their useful life, after theft or loss by a prior occupant, and within 30 days of written notice of a manufacturing defect. Occupants must keep battery-operated units in good repair and replace any that are stolen, missing, or damaged during their own occupancy. Tampering with or disabling a required detector, other than for battery replacement or maintenance, is unlawful. HPD, DOB, FDNY and DOHMH can all enforce this section.
Violations & Fines
Owners who fail to install or replace required smoke detectors face Housing Maintenance Code violations issued by HPD, DOB, FDNY or DOHMH; tampering with or disabling a working detector outside of normal maintenance is separately unlawful under § 27-2045(d).
