HB 1091 was signed into law earlier this week by Governor Bill Ritter. The law affects all new and existing homes (single-family or multi-family) being rented or sold. The Colorado Association of Realtors provides the following summary:
“Beginning July 1, 2009, a seller of residential real property containing a fuel-fired heater or appliance, a fireplace, or an attached garage will be responsible for assuring that a carbon monoxide alarm is properly installed within 15 feet of the entrance to each room lawfully used for sleeping. No person shall have a claim for relief against a property owner or their authorized agent if a carbon monoxide alarm is installed in accordance with the manufacturer’s published instructions.”
