The water closet shall be positioned with a wall or partition to the rear and to one side. The centerline of the water closet shall be 16 inches (405 mm) minimum to 18 inches (455 mm) maximum from the side wall or partition, except that the water closet shall be 17 inches (430 mm) minimum and 19 inches (485 mm) maximum from the side wall or partition in the ambulatory accessible toilet compartment specified in 604.8.2. Water closets shall be arranged for a left-hand or right-hand approach.
ETA Editor’s Note:
The 1991 ADA Standards allowed construction tolerances from an 18” absolute dimension. This might allow a little more than the 18” maximum under the 2010 ADA Standards to be safe harbored.
