Figure 4. Minimum Clear Floor Space for Wheelchairs.
Figure 4(a) Clear Floor Space. 30 inches (760 mm) by 48 inches (1220 mm).
Figure 4(b) Forward Approach. With a wheelchair facing a wall, element or surface -- 30 inches (760 mm) wide by 48 inches (1220 mm) deep.
Figure 4(c) Parallel Approach. With a wheelchair postioned beside a wall, element or surface to the side -- 48 inches (1220 mm) long by 30 inches (760 mm) wide.
Figure 4(d) Clear Floor Space in Alcoves. For a forward approach, where the depth of the alcove is equal to or less than 24 inches (610 mm), the required clear floor space is 30 inches (760 mm) wide by 48 inches (1220 mm) deep. For a parallel (side) approach, where the depth of the alcove is equal to or less than 15 inches (380 mm), the width is 30 inches (760 mm) and the length is 48 inches (1220 mm).
Figure 4(e) Additional Maneuvering Clearances for Alcoves. For a forward approach, if the depth of the alcove is greater than 24 inches (610 mm), then in addition to the 30 inches (760 mm) width, a maneuvering clearance of 6 inches (150 mm) in width is required, for a total width of 36 inches (915 mm).
For a parallel approach, where the depth of the alcove is greater than 15 inches (380 mm), then in addition to the 48 inches (1220 mm) length, an additional maneuvering clearance of 12 inches (305 mm) in length is required, for a total length of 60 inches (1525 mm).
