Test smoke and carbon monoxide alarms in each unit. Michigan requires smoke alarms in or near each sleeping room and on every level including the basement, even in homes built before November 6, 1974, and the owner must keep them working and repair a failed alarm within 30 days, while carbon monoxide alarms are required in newly built homes, permitted renovations, and wherever a local code calls for them, so a yearly documented test of every alarm confirms each unit is covered and catches dead alarms early.
