ADA Regulations & Required Number of Accessible Spaces

ADA regulations and standards are issued by the Department of Justice and the Department of Transportation and require certain specifications for each parking facility. These requirements apply to public and restricted parking.

Number of Spots:

  • ada regulations for accessible spots

    The minimum number of accessible spaces must be calculated separately for each parking facility – not as a combined total on site.

  • One of every 6 accessible spots (or a fraction of 6) must be sized to accommodate a van.
  • 501-1000 spaces within a facility requires 2% of the total to be accessible.
  • 1001 and over requires 20 + 1 for each 100 or fraction over 1000.


  • If a parking area serves more than one entrance, accessible spaces must be spread among entrances that are accessible.
  • Accessible parking must be located on the shortest accessible route to that accessible entrance.
  • In some cases, the shortest route may require the accessible spots to be located near the closest entrance ramp, rather than entrance door.

Parking Garage:

  • In parking garages that do not serve a facility, accessible spots must be located on the shortest accessible route to an assessable entrance.
  • Each direct connection to a facility must include an accessible entrance.

Hospital & Rehabilitation Facilities:

  • For obvious reasons, outpatient hospitals and rehabilitation facilities require more accessible parking spaces.
  • At least 20% of patient and visitor parking spaces must be accessible at outpatient physical rehabilitation centers.

  • Accessible routes must connect directly to access aisles.
  • A landing at least 36” deep is required at the top of curb ramps.
  • Spaces must be marked at a 96” minimum width.
  • Access aisle must be at least 60” wide.
  • 2 spaces can share one aisle.
  • Parking spaces and access aisle must be marked.

  • 98” minimum is required for vertical clearance.


  • Accessible spaces must be clearly identified with signage containing the International Symbol of Accessibility.
  • Signs must be at least 60” high and can be on a post or suspended from ceilings.


  • Accessible spaces are required where parking lots are altered or added.
