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. 7
