Wheelchair spaces shall not be located on, or be obstructed by, temporary platforms or other movable structures.

 Advisory 11B-221.2.4 Removable chairs. Readily removable seats should be designed to facilitate easy, timely and frequent removal and installation.  If mechanically fastened to the floor the release mechanisms need to be easily operated by untrained individuals without special tools or knowledge.  Seats which have been removed need to be stored so as not to create obstructions. ◼
