Public Way minimum width/height

Public Way minimum width/height

• A. Not less than 12 ft in width or height.
• B. Not less than 10 ft in width and height.
• C. Not less than 8 ft in width and height.
• D. Not less than 15 ft in width and 6 ft in height.

Answer: (B)

Public Way dimensions ensure the exit path to the exterior has enough space for safe egress and for emergency operations. The Life Safety Code requires not less than 10 feet in width and not less than 10 feet in height for a public way. This minimum gives adequate room for people evacuating and for responders or equipment to move through without obstruction, while still keeping the area simple and consistent across occupancies. So the standard isn’t about a larger size by default; it’s about guaranteeing a floor-to-ceiling and horizontal clearance of at least 10 feet. Anything that asks for a smaller height or width would create potential bottlenecks or headroom problems, while larger numbers are acceptable but not the minimum.
