ADA Handicap Accessible Parking Regulations:

When parking is provided for the public, designated accessible parking spaces must be provided, if doing so is readily achievable.

An accessible parking space must have space for the vehicle and an additional space located either to the right or to the left of the space that serves as an access aisle. This aisle is needed to permit a person using a wheelchair, electric scooter, or other mobility device to get out of their car or van.


Accessible handicapped parking must be located on the shortest accessible route to the accessible entrance. Provide a marked access aisle if person is required to cross vehicular traffic.

Minimum Number

One in every eight, but not less than one, parking space must be van accessible with a designated handicap sign and an access aisle 96" wide.

Total Spaces in Lot Accessible Spaces Required
1-25 1 van
26-50 1 std. + 1 van
51 - 75 2 std. + 1 van
76-100 3 std. + 1 van

 * One in every 8 accessible parking spaces must be a van accessible space with an 8 foot wide access aisle.

State and local government have the authority to adopt and enforce their own building codes, but must meet or exceed those contained in the ADA. Be sure to check your state and local regulations before planning or beginning your project.

Additional (TAS) Texas Handicap Parking Regulations

Location. Accessible parking spaces serving a particular building shall be located on the shortest accessible route of travel from adjacent parking to an accessible entrance. In parking facilities that do not serve a particular building, accessible parking shall be located on the shortest accessible route of travel to an accessible pedestrian entrance of the parking facility. In buildings with multiple accessible entrances with adjacent parking, accessible parking spaces shall be dispersed and located closest to the accessible entrances. Accessible routes shall be located so that users are not required to wheel or walk behind parked vehicles (except the one they operate or in which they are a passenger) or in traffic lanes.

Parallel parking is discouraged unless it can be situated so that persons entering and exiting vehicles will be out of the flow of traffic. If parallel parking is located on a street, driveway, or any other area where vehicular traffic exists, the space shall be designed and located so that users are out of the flow of traffic.

Parking Spaces. Accessible parking spaces shall be at least 96 in wide. Parking access aisles shall be part of an accessible route to the building or facility entrance. Two accessible parking spaces may share a common access aisle. Parked vehicle overhangs shall not reduce the clear width of an accessible route. Parking spaces and access aisles shall be level with surface slopes not exceeding 1:50 (2%) in all directions.

Signage. Each accessible parking space shall be designated as reserved by a vertically mounted or suspended sign showing the symbol of accessibility. Van accessible spaces shall have an additional sign "Van-Accessible" mounted below the symbol of accessibility. Characters and symbols on such signs shall be located 60" minimum above the ground, floor, or paving surface so they cannot be obscured by a vehicle parked in the space.

Vertical Clearance. Provide minimum vertical clearance of 114 in. at accessible passenger loading zones and along at least one vehicle access route to such areas from site entrance(s) and exit(s). At parking spaces provide minimum vertical clearance of 98 in. at the parking space and along at least one vehicle access route to such spaces from site entrance(s) and exit(s).

Passenger Loading Zones. Passenger loading zones shall provide an access aisle at least 60 in. wide and 20 ft. long adjacent and parallel to the vehicle pull-up space. If there are curbs between the access aisle and the vehicle pull-up space, then a curb ramp shall be provided. Vehicle standing spaces and access aisles shall be level with surface slopes not exceeding 1:50 (2%) in all directions.
