ADA Guidelines: ADA Parking Standards

The following ADA guidelines for parking standards present requirements that must be met on most construction projects. Verify if your construction project is in compliance with these ADA guidelines. Public accommodations and commercial facilities must follow the requirements of the 2010 Standards, including both the Title III regulations at 28 CFR part 36, subpart D; and the 2004 ADAAG at 36 CFR part 1191, appendices B and D.

ADA Design Guidelines: Parking Access

  • ADA guidelines specifies that access aisles for car and van parking spaces, must be measured from the centerline of the marking. However, if the parking space or the access aisles is not adjacent to another parking, measurement could be made including the full width of the line.
  • Designed van parking spaces shall be a minimum 132 inches wide and must contain an access aisle. If it is a car parking space it shall be 96 inches width. However, van parking spaces could be 96 inches wide only if the access aisle is 96 inch wide.
  • Access aisles shall be adjacent to an accessible route, connecting parking spaces to entrances. Two parking spaces shall be permitted to share a common access aisle. Avoid using accessible routes behind parked vehicles. If the accessible route crosses traffic lanes, it shall be visibly marked enhancing pedestrian safety.
  • Access aisles shall be 60 inches wide minimum and should extend the full length of the parking space being served. Remember to mark access aisles to prevent vehicles from parking over the aisles.
  • The aisles must be marked clearly; however, the method and color of marking are specified by State or local laws. Aisles shall be allowed to be marked on either side of the parking space. Hint: Van aisles are recommended to be placed on the passenger side of the van space.
  • Aisles shall be at the same level as the parking space they are serving. Level changes are not allowed, and constitute a violation of ADA Design standards. Aisles slopes not steeper than 1:48 shall be permitted.
  • Access aisles should be leveled in all directions. Built-up curb ramps are not permitted to project into access aisles and parking spaces because they would create slopes greater than 1:48.
  • Parking space identification must include the International Symbol of Accessibility. ADA Design standards request that signs identifying van parking spaces shall contain the “van accessible” sign. Signs should be installed at least 60 inches above finish floor.
  • It is important to prevent vehicles or vans to obstruct the required clear width of accessible route. Parking spaces for vans and access aisles and vehicular routes serving them shall provide a minimum vertical clearance of 98 inches
  • ADA Design Guidelines: Loading Zones

  • Passenger loading zones shall not overlap the traffic way as stated on ADA guidelines. Passenger loading zones per ADA Design Guidelines must provide a pull-up space of 96 inches minimum width and 20 feet long minimum distance.
  • Aisles serving pull-up passenger spaces must be 60 inches wide minimum and should extend the full length of the vehicle they serve. Marking passenger loading zones is strongly recommended to prevent vehicles from parking in them.
  • ADA design guidelines also recommend that vehicle pull-up spaces and access aisles shall be at the same level as the vehicle pull-up space they are serving. Level changes are not allowed. Slopes not steeper than 1:48 shall be permitted.
  • Vehicle pull-up spaces, access aisles serving them, and a vehicular route from an entrance to the passenger loading zone and from the passenger loading zone to a vehicular exit shall provide a vertical clearance of 114 inches minimum.
