Mount Vernon enforces the New York State Uniform Fire Prevention and Building Code (19 NYCRR Part 1225, incorporating the 2020 Fire Code of NYS), which requires smoke alarms in every sleeping room, outside each sleeping area, and on every story of a dwelling. New construction alarms must be hardwired with battery backup and interconnected; replacement battery-only alarms must use a sealed 10-year battery.
Mount Vernon does not maintain a stand-alone local smoke-alarm code; it enforces state requirements through the Department of Buildings and Fire Prevention Division under Chapter 131 (Fire Prevention) and Chapter 149 (Housing Standards) of the city code. The state framework is 19 NYCRR Part 1225, which incorporates by reference the 2020 Fire Code of New York State and (through Part 1219) the 2020 Residential Code. Section R314 of the Residential Code requires smoke alarms in each sleeping room, outside each separate sleeping area in the immediate vicinity of the bedrooms, and on each additional story including basements. New construction and substantial alterations require alarms to receive primary power from building wiring with battery backup and to be interconnected so that one alarm activates all alarms in the unit. Battery-only replacements sold or installed in New York since April 1, 2019 must use a sealed, non-removable 10-year battery (NY General Business Law section 399-ccc). Alarms must be replaced when they fail an operability test or after 10 years from manufacture date. Carbon monoxide alarms are separately required by Amanda's Law in any dwelling with a fuel-burning appliance, fireplace, or attached garage. Vacant-apartment inspections by the Department of Buildings include verifying smoke and CO alarms before issuing a Certificate of Occupancy.
Failing to install, maintain, or interconnect smoke alarms as required by 19 NYCRR Part 1225 (R314) is a fire code violation citable by the Mount Vernon Fire Prevention Division and can block issuance of a Certificate of Occupancy; selling non-compliant battery alarms violates NY General Business Law section 399-ccc.
