Width [4.3.3.] and Passing Space [4.3.4]
A continuous minimum clear width of 36 inches is required for accessible routes, but a reduction to 32 inches is allowed for a linear distance of no more than 24 inches (e.g., a doorway). However, the minimum width of hallways and corridors is often further determined by ADAAG requirements for clear floor space at elements such as drinking fountains, door maneuvering clearances, and turns around obstructions. Wheelchair passing space at least 60 by 60 inches must be provided at reasonable intervals that do not exceed 200 feet.
