Overhead Hazards. As an example, the diagram illustrates a stair whose underside descends across a pathway. Where the headroom is less than 80 inches, protection is offered by a railing (2030 mm) which can be no higher than 27 inches (685 mm) to ensure detectability.
The minimum clear width for continuous passage is 36 inches. Thirty two (32) inches is the minimum clear width for a maximum distance of 24 inches (610 mm). The maximum distance an object can protrude beyond a wing wall is 4 inches (100 mm).

The shelves can be adjustable. The maximum distance from the user to the shelf shall be 21 inches (535 mm).
If the clear floor space allows a parallel approach by a person in a wheelchair and the distance between the wheelchair and the clothes rod exceeds 10 inches, the maximum high side reach shall be 48 inches (1220 mm). The maximum distance from the user to the clothes rod shall be 21 inches (535 mm).
