Pursuant to legislation approved in 2005, the New York State Uniform Fire Prevention and Building Code now requires the installation of carbon monoxide detectors in newly constructed multiple dwellings or multiple dwellings offered for sale. The code defines “multiple dwellings” as a building occupied by three or more individuals or families living independently of each other. This amendment expands on 2002 legislation that requires the installation of operable carbon monoxide detectors in one- and two-family dwellings, condominiums and cooperatives.
