Note: This document or portion of document references a state or local code that is stricter than the 2010 ADA Standards requires.

11B-502.7 Relationship to accessible routes.

Parking spaces and access aisles shall be designed so that cars and vans, when parked, cannot obstruct the required clear width of adjacent accessible routes.

[2010 ADAS] Advisory 502.7 Relationship to Accessible Routes. Wheel stops are an effective way to prevent vehicle overhangs from reducing the clear width of accessible routes.

11B-502.7.1 Arrangement.

Parking spaces and access aisles shall be designed so that persons using them are not required to travel behind parking spaces other than to pass behind the parking space in which they parked.

Advisory 11B-502.7.1 Arrangement. Accessible parking spaces located so that the accessible route passes behind parked vehicles create a safety hazard, especially for wheelchair users. Wheelchair users traveling behind parked vehicles may be obscured from the view of drivers backing out of parking spaces, especially when passing behind high-profile vehicles. This section requires that persons with disabilities not be required to travel behind parking spaces other than the one in which they have parked. ◼

ETA Editor's Note

While 2010 ADAS Advisory 502.3 discourages configuring access aisles to require travel behind other parked vehicles, CBC 11B-502.7.1 prohibits this.

11B-502.7.2 Wheel stops.

A curb or wheel stop shall be provided if required to prevent encroachment of vehicles over the required clear width of adjacent accessible routes.
