Test smoke and carbon monoxide detectors and log maintenance. Wisconsin owners must install smoke detectors and, where the home or building has a fuel-burning appliance, fireplace, or attached garage, carbon monoxide detectors, must maintain the common-area smoke detectors and every CO detector in buildings of 3 or more units, and must fix a unit's detector within 5 days of a tenant's written notice that it is not working, so a documented annual test keeps you compliant and defensible.
