Smoke Detector Rules in the State of Wisconsin

Type of Detectors

• Smoke detectors must be UL approved. UL stands for Underwriters Laboratories. Products with this seal of approval meet various safety standards to ensure consumers are protected. UL tests products rigorously before awarding the UL mark.

Number Required

• One- and two-family homes must have at least one smoke detector per floor. Basements and finished attics must also have a smoke detector installed. The state suggests you place the detectors between the sleeping area and the rest of the home as well as near the ceiling of each stairwell.

Installation Requirements

• The state recommends you follow the manufacturer's instructions for mounting your detectors properly. Typically this includes tips to place the detectors away from kitchens and areas of high humidity.

Maintenance Requirements

• According to the state of Wisconsin, you should test the unit weekly, change your smoke detector's batteries at least once per year or when the low battery light appears, monitor warning lights and replace burnt-out bulbs and vacuum the interior of the unit yearly to remove dust.

Landlord and Tenant Requirements

• The state of Wisconsin requires that landlords maintain all smoke detectors located in public areas. They must also inform tenants in writing of smoke detector maintenance requirements. If you are a tenant and your smoke detector is not working or needs maintenance attention, contact your landlord immediately. The landlord then has five days to resolve the issue. If the issue is not resolved within within five days, contact your municipality's building inspection department to lodge a complaint.
