    Default carbon monoxide detector requirement

    Anyone know the requirement for carbon monoxide detectors for new construction? Years ago I was told that June 2010 and newer needed one CO detector per floor and that has been what I have found installed in new houses (if they remembered at all.) However, AHJ guy told me the other day that the requirement is one per house not per floor. Is he right?

    Don't have code reference but have always heard one per house. In Mecklenburg Co. it doesn't matter the age of the house, it can't be sold without one.

    This is a building code issue, not an electrical code issue.

    It also varies from state to state, area to area.

    In Florida, in a house which has a fossil fuel burning appliance and/or an attached garage, a carbon monoxide detector is required within 10 feet of any room used for sleeping.

    From the 2009 IRC:
    - R315.1 Carbon monoxide alarms. For new construction, an approved carbon monoxide alarm shall be installed outside of each separate sleeping area in the immediate vicinity of the bedrooms in dwelling units within which fuel-fired appliances are installed and in dwelling units that have attached garages.
