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.
The required number of accessible parking spaces must be calculated separately for each parking facility, not calculated based on the total number of parking spaces provided on a site. One of six (or fraction of six) accessible parking spaces, but always at least one, must be van accessible.
Note: Parking for hospital outpatient facilities, rehabilitation facilities, outpatient physical therapy facilities or residential facilities have substantially different requirements for accessibility.

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 or structure:
- 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.
Note: Accessible parking spaces may be clustered in one or more facilities 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).
