Carbon monoxide alarms required in 1 & 2 family residential structures
As of February 1, 2011, there are Wisconsin requirements for both smoke alarms and carbon monoxide alarms in almost all one- and two-family dwellings, regardless of the building’s age. The new carbon monoxide safety net is for dwellings with fuel burning appliances, fireplaces or attached garages.
Owners and Renters Have Responsibilities
Owners are responsible for alarm installations and occupants have responsibility to maintain the alarms. Owners must repair or replace alarms within five days of written notice from an occupant or an inspector. Authorized inspectors may enter dwellings to inspect alarms when requested by owners or occupants. Tampering with alarms is illegal, dangerous, and can cause serious liability concerns.
Where and What Kinds?
Alarms must be installed in the basement, and on each floor level. The alarms need not be installed in attics, garages, or storage areas. The alarms may be separate or combination units, powered by batteries, or in the case of new construction, tied into the home’s electrical system, interconnected with battery backup. Installation must follow manufacturers’ instructions. Those instructions are provided with new alarms and usually can be found on the manufacturers’ Web sites. The manufacturer should be identified on the alarm. Alarms used in Wisconsin must be approved by Underwriters Laboratories.
