What minimum ceiling height is required for a legal basement bedroom in NJ?

The New Jersey Uniform Construction Code requires a minimum clear ceiling height of 7 feet for any room used as a habitable space, including bedrooms. This measurement is taken from the finished floor to the underside of the finished ceiling, meaning ductwork, beams, and joists that drop below 7 feet can cause a room to fail the habitability standard even if the structural height is adequate.

Basement bedrooms also require a code-compliant egress window, smoke and carbon monoxide detectors, and proper lighting and electrical outlets to be legally classified as sleeping rooms.

Many NJ basement ceilings fall between 5 feet 6 inches and 6 feet 6 inches, which makes floor lowering one of the most direct ways to reach the 7-foot habitability threshold without altering the structure above.
