    Minimum ceiling height

    Minimum ceiling height

    New postby mmarcley on Sat Dec 05, 2009 3:13 pm

    What is the minimum ceiling height for a bedroom in Wilmington, NC? It is a finished room above a garage and the current finished height is 7"2", but it has no closet and the plans call it "storage." I am going to dormer the room, but cannot easily get more than the 7'2" for half the room.

    Hi Mark,

    The minimum ceiling height in the North Carolina Residential Code, which is based on the International Residential Code, is: (underlining and bold are mine)
    - - R305.1 Minimum height.
    - - - Habitable rooms, hallways, corridors, bathrooms, toilet rooms, laundry rooms and basements shall have a ceiling height of not less than 7 feet (2134 mm). The required height shall be measured from the finish floor to the lowest projection from the ceiling.
    - - - - Exceptions:
    - - - - - 1. Beams and girders spaced not less than 4 feet (1219 mm) on center may project not more than 6 inches (152 mm) below the required ceiling height.
    - - - - - 2. Ceilings in basements without habitable spaces may project to within 6 feet, 8 inches (2032 mm) of the finish floor; and beams, girders, ducts or other obstructions may project to within 6 feet, 4 inches (1931 mm) of the finished floor.
    - - - - - 3. Not more than 50 percent of the required floor area of a room or space is permitted to have a sloped ceiling less than 7 feet (2134 mm) in height with no portion of the required floor area less than 5 feet (1524 mm) in height.

    Your description of having 7 feet 2 inches available sounds like you will not have any problems in meeting the minimum ceiling height, but you will not have a lot of room to spare either.

    A large room will feel cramped with only a 7 foot ceiling.
