In 2008 the Minnesota CO2 law required all existing homes to have CO2 detectors within 10 feet of any sleeping room. So now no matter how old your home is the state law requires you to have CO2 alarms. Furthermore, in 2009 the state required all multi-family properties(apartments) to have CO2 alarms installed in them. For those of you who have investment properties this is important to make sure you are following the state laws and providing this important safety feature.
All residential property must have smoke detectors in the following areas:
1) In every sleeping room.
2) Outside each separate sleeping area in the immediate vicinity of the bedrooms.
3) On each additional story of the dwelling, including basements but not including crawl spaces and uninhabitable attics. In dwellings or dwelling units with split levels, a smoke alarm installed on the upper level shall suffice for the adjacent lower level provided that the lower level is less than one full story below the upper level.
