Residential Building Inspector B1Building Planning and Life SafetyMedium
A residential building inspector is reviewing plans for a new single-family dwelling. The plans include a habitable attic space. What is the minimum clear headroom required in the habitable attic space over at least 50 percent of its area?
- A7 feet (2134 mm)
- B6 feet (1829 mm)
- C6 feet 4 inches (1930 mm)
- D6 feet 8 inches (2032 mm)
Show answer & explanationAnswer & explanation
Correct answer: A. 7 feet (2134 mm)
Habitable spaces, including attics, must meet minimum headroom requirements to ensure comfortable and safe occupancy. The code specifies a minimum height over a significant portion of the floor area.
Why the other options are wrong
- B. This headroom is insufficient for a habitable space.
- C. This headroom is insufficient for a habitable space.
- D. This is the minimum height for portions of ceilings in habitable spaces, but not the overall minimum for 50% of the area.
Habitable Attic Headroom
Habitable attic spaces must have a minimum clear headroom over a specified percentage of their floor area to be considered usable.
- Applies to habitable spaces, not just storage attics.
- Ensures adequate vertical clearance for occupants.
- Portions with sloped ceilings may have less height.
Memory trick: Seven feet high, for half the sky, in your attic, where dreams fly.
