Smoke detectors are required to be installed per manufacturer's instructions in each location as follows:
Outside of each separate sleeping area in the immediate vicinity of the bedrooms
Inside each bedroom
On each floor including basements and/or garages
Smoke detector violations must be corrected on the same day as the inspection. Failure to correct such violation by 4 p.m. of the day of the inspection will result in that unit and/or the entire building being vacated and condemned as an unsafe structure. (2003 ICC International Property Maintenance Code PM-108.1.1 "Unsafe Structure" - not providing minimum safeguards to protect or warn occupants in the event of a fire.)
Carbon Monoxide Detectors are required outside of each bedroom.
