What is the minimum size of habitable rooms in a house according to the building code?
Wednesday, July 4, 2018
Every residential dwelling must have one habitable room that is at least 120 square feet, which is usually the living area of the home. Other habitable rooms must be a minimum of 70 square feet, with one wall not less than seven feet in length. Although the kitchen is considered a habitable room, it can be a little smaller at a minimum of 50 square feet.
Any area of a room that has less than a seven foot flat ceiling, or any area with a sloped ceiling that is less than five feet high, cannot be counted towards the minimum square footage requirements. Bathrooms, hallways, closets and utility rooms are not counted as habitable spaces.
By the way, no minimum total square footage of a residence is addressed by the International Residential Code (IRC) or Florida Building Code (FBC), but is usually specified by local zoning and deed restrictions.
