Starting April 1, 2010, the State of Wisconsin is requiring carbon monoxide detectors in public residential buildings. (See 2007 Senate Bill 289) “Residential building” means a tourist rooming house, a bed and breakfast establishment or any public building that is used for sleeping or lodging purposes.
The law basically require that a carbon monoxide detector to be installed within 15 feet of any fuel-burning appliance.
Unlike smoke detectors, carbon monoxide detectors have a limited life. Be sure to check with the manufacturer of the detector to determine when the unit needs to be replaced.
