What is the minimum ceiling height?
Saturday, August 4, 2018
Minimum ceiling heights are defined by the building codes for “habitable rooms.” This means rooms intended to be occupied, as opposed to storage spaces, and the minimum height is 7 feet, per International Residential Code (IRC) and the residential edition of the Florida Building Code (FBC R305). However, there are exceptions allowed, along with qualifiers:
- Bathrooms, toilet rooms, and laundry rooms can be as low as 6 feet 8 inches.
- Rooms with sloped ceilings must have a minimum of 50% of the room at seven feet high or taller.
- Because the minimum square footage of a habitable room is 70 square feet, there is also a qualifier that any area of a room with a ceiling below five feet does not count towards habitable space minimum square footage.
- Also, sloped ceilings in a bathrooms must be a minimum of 6 feet 8 inches in front of the plumbing fixture, such as a sink or toilet.
