ADA Design Guide 1 – Restriping Parking Lots
Accessible Parking Spaces
When a business, State or local government agency, or other covered entity restripes a parking lot, it must provide accessible parking spaces as required by the ADA Standards for Accessible Design. Failure to do so would violate the ADA.
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 lots when it is readily achievable to do so. Because restriping is relatively inexpensive, it is readily achievable in most cases.
This ADA Design Guide provides key information about how to create accessible car and van spaces and how many spaces to provide when parking lots are restriped.

Accessible Parking Spaces for Cars
Accessible parking spaces for cars have at least a 60-inch-wide access aisle located adjacent to the designated parking space. The access aisle is just wide enough to permit a person using a wheelchair to enter or exit the car. These parking spaces are identified with a sign and located on level ground.
Van-Accessible Parking Spaces
Van-accessible parking spaces are the same as accessible parking spaces for cars except for three features needed for vans:
a wider access aisle (96″) to accommodate a wheelchair lift;
vertical clearance to accommodate van height at the van parking space, the adjacent access aisle, and on the vehicular route to and from the van-accessible space, and
an additional sign that identifies the parking spaces as “van accessible.”
One of eight accessible parking spaces, but always at least one, must be van-accessible.
(illustration showing a van with a side-mounted wheelchair lift lowered onto a marked access aisle at a van-accessible parking space. A person using a wheelchair is getting out of the van. A dashed line shows the route from the lift to the sidewalk.)
Features of Accessible Parking Spaces for Cars
(plan drawing showing an accessible parking space for cars with a 96 inch wide designated parking space, a 60 inch wide min. marked access aisle and the following notes)
Sign with the international symbol of accessibility mounted high enough so it can be seen while a vehicle is parked in the space.
If the accessible route is located in front of the space, install wheelstops to keep vehicles from reducing width below 36 inches.
Access aisle of at least 60-inch width must be level (1:50 maximum slope in all directions), be the same length as the adjacent parking space(s) it serves and must connect to an accessible route to the building. Ramps must not extend into the access aisle.
Boundary of the access aisle must be marked. The end may be a squared or curved shape.
Two parking spaces may share an access aisle.
Three Additional Features for Van-Accessible Parking Spaces

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.
When accessible parking spaces are added in an existing parking lot, locate the spaces on the most level ground close to the accessible entrance. An accessible route must always be provided from the accessible parking to the accessible entrance. An accessible route never has curbs or stairs, must be at least 3- feet wide, and has a firm, stable, slip-resistant surface. The slope along the accessible route should not be greater than 1:12 in the direction of travel.
Accessible parking spaces may be clustered in one or more lots if equivalent or greater accessibility is provided in terms of distance from the accessible entrance, parking fees, and convenience. Van-accessible parking spaces located in parking garages may be clustered on one floor (to accommodate the 98-inch minimum vertical height requirement).
