When a business or State or local government restripes parking spaces in a parking lot or parking structure (parking facilities), it must provide accessible parking spaces as required by the 2010 ADA Standards for Accessible Design (2010 Standards).
In addition, businesses or privately owned facilities that provide goods or services to the public have a continuing ADA obligation to remove barriers to access in existing parking facilities when it is readily achievable to do so. Because restriping is relatively inexpensive, it is readily achievable in most cases. State and local government facilities also have an ongoing ADA obligation to make their programs accessible, which can require providing accessible parking.
Accessible parking spaces must be located on the shortest accessible route of travel to an accessible facility entrance. Where buildings have multiple accessible entrances with adjacent parking, the accessible parking spaces must be dispersed and located closest to the accessible entrances.

1. Parking space identification sign with the international symbol of accessibility mounted 84 inches minimum above the ground surface measured to the bottom of the sign.
2. If the accessible route is located in front of the parking space, install wheel stops to keep vehicles from reducing the clear width of the accessible route below 36 inches.
3. Two parking spaces may share an access aisle except for angled parking spaces (see below).
Access aisle width is at least 60 inches, must be at the same level and the same length as the adjacent parking space(s) it serves, maximum slope in all directions is 1:48, and access aisle must connect to an accessible route to the building. Ramps must not extend into the access aisle.
4. Parking space shall be 144 inches wide minimum, marked to define the width, and maximum slope in all directions is 1:48.
5. Boundary of the access aisle must be clearly marked so as to discourage parking in it. (State or local laws may address the color and manner that parking spaces and access aisles are marked.)
