A new law takes effect in November 2009 that requires the installation of carbon monoxide detectors in addition to smoke detectors in certain buildings. View the specific requirements here.
The Legislature recently modernized Maine’s law that applies to smoke detectors (a law that hasn’t been updated in eleven years) and to create a new law to deal with carbon monoxide detectors. An Act to Protect Maine Residents from Home Fires and Carbon Monoxide requires all newly-constructed single family and multi-apartment dwellings constructed or sold in the state to have both smoke detectors and carbon monoxide detectors that meet certain specifications and are installed in certain locations within those residential units.
