The City of Philadelphia’s Carbon Monoxide Law went into effect on January 1, 2009. This ordinance requires owners of all one and two-family dwellings and small residential care/assisted living facilities to install Carbon Monoxide (CO) detection and alarm devices in their buildings. This is similar to the requirement that smoke detectors be installed and working in all residential buildings. More information and specific requirements of the law can be found here.
