Rockland County, NY Building Safety: Carbon Monoxide Detectors (2026)

Adopted January 21, 2003 by Local Law No. 2-2003 after legislative findings that carbon monoxide poisoning in homes is preventable through proper detectors (Section 224-1), the chapter defines a compliant device as a UL-approved carbon monoxide detector and alarm assembly with a digital readout of concentration and, if hardwired, an independent battery backup (Section 224-2). Section 224-3 sets placement: detectors go in hallways no less than eight feet from each bedroom on every floor of a one- or two-family dwelling or mobile home, and on every floor of a multiple dwelling, hotel or motel within 40 feet of doors to dwelling units or sleeping areas in a corridor; units may be hardwired with no intervening switch, plugged in, or battery-powered, but not mounted in dead-air spaces.

Section 224-4 phases in compliance: new multiple dwellings, hotels, motels and rooming houses built or occupied after January 1, 2003 needed detectors before occupancy or transfer; existing multiple dwellings, hotels and motels had until April 1, 2003; one- and two-family dwellings and mobile homes must have detectors installed before any closing of title occurring after January 1, 2004. Owners must give the Rockland County Health Department proof of installation on a form set by the County Health Commissioner, who may also adopt implementing regulations subject to Legislature approval (Section 224-5), and the Health Department and Department of Fire and Emergency Services were directed to develop a public-education plan (Section 224-6).
