Chapter 3: Building Blocks Clear Floor or Ground Space and Turning Space
Turning Space [§304]
Turning space is required in these accessible rooms and spaces:
toilet and bathing facilities
dressing, fitting, and locker rooms
transient lodging guest rooms
dwelling units (all rooms on an accessible route)
patient bedrooms
holding and housing cells
saunas and steam rooms
raised courtroom stations served by ramps or lifts with entry ramps
certain recreation spaces (amusement ride load/ unload areas, fishing piers and
platforms, play components, and shooting facilities)
Space for turning is also required along accessible routes where a 180 degree turn
around an obstruction less than 48” wide is required (§403.5.2).
Clear Width at 180 Degree Turn Around a Narrow Obstruction
< 48”
60” min
(48” min if both connecting
routes are 42” min wide)
Recommendation: Turning space is recommended in small spaces with
entrapment risks as well as at dead-end aisles and corridors so that people
using wheeled mobility aids do not have to back up considerable distances.
