Where the toilet room or bathing room is for individual use and a clear floor space complying with Section 11B-305.3 is provided within the room beyond the arc of the door swing, doors shall be permitted to swing into the clear floor space or clearance required for any fixture.

ETA Editor's Note
Limiting the encroachment of door swings into the wheelchair turning space, and lacking Exception 1 above allowed by 2010 ADA Standards, the CBC requirements pertaining to toilet or bathing room clearances are more stringent.

Mirrors located above lavatories or countertops shall be installed with the bottom edge of the reflecting surface 40 inches (1016 mm) maximum above the finish floor or ground. Mirrors not located above lavatories or countertops shall be installed with the bottom edge of the reflecting surface 35 inches (889 mm) maximum above the finish floor or ground.

In order for mirrors to be usable by people who are ambulatory and people who use wheelchairs, the top edge of mirrors should be 74 inches (1880 mm) minimum from the floor or ground. ◼

ETA Editor's Note

The CBC 11B-603.5 limitation on the height of accessories at toilet rooms is more stringent than 2010 ADA Standards. At locations other than toilet rooms, they are equivalent.

Toilet and bathing rooms within guest rooms that are not required to provide mobility features complying with Section 11B-806.2 shall provide all toilet and bathing fixtures in a location that allows a person using a wheelchair measuring 30 inches by 48 inches (762 mm by 1219 mm) to touch the wheelchair to any lavatory, urinal, water closet, tub, sauna, shower stall and any other similar sanitary installation, if provided.

Advisory 11B-603.6 Guest room toilet and bathing rooms. At Housing at a Place of Education subject to Section 11B-224.7, toilet rooms serving sleeping rooms complying with Sections 11B-806 or 11B-809 offer greater accessibility than required by Section 11B-603.6. ◼
