Please look at the photo on the right. What you are looking at is an Americans with Disabilities Act (ADA) accessible parking area at a resort hotel in Hilton Head, SC. There are four accessible parking spaces and three access aisles. But what’s wrong?

HINT: Access aisles must be level.

Every accessible parking space should have an access aisle that is mostly level and at the same elevation as the accessible parking space. Two accessible parking spaces can share a common aisle. The photo below is a closeup of one of the access aisles. At the far end of each access aisle is a curb ramp that projects into the access aisle and connects to the sidewalk that leads to the hotel main entrance and lobby. The run slope of the curb ramps exceeds 5%. The photo is representative.

2010 ADA Standard 502.4, [Parking Spaces] Floor or Ground Surfaces, states, “Parking spaces and access aisles serving them shall comply with 302. Access aisles shall be at the same level as the parking spaces they serve. Changes in level are not permitted. EXCEPTION: Slopes not steeper than 1:48 [2.08%] shall be permitted.” In other words, access aisles and accessible parking spaces must be mostly level in all directions, and the parking space and access aisle must be at the same level, or elevation, for the full length of the parking space.

2010 ADA Standard 502.2, [Parking Spaces] Vehicle Spaces, states, “Car parking spaces shall be 96 inches (2440 mm) wide minimum and van parking spaces shall be 132 inches (3350 mm) wide minimum, shall be marked to define the width, and shall have an adjacent access aisle complying with [Standard] 502.3.” The diagram below is representative of an ADA access aisle and an accessible parking space.

2010 ADA Advisory 502.4, [Parking Spaces] Floor or Ground Surfaces, states, “Access aisles are required to be nearly level in all directions to provide a surface for wheelchair transfer to and from vehicles. The exception allows sufficient slope for drainage. Built-up curb ramps are not permitted to project into access aisles and parking spaces because they would create slopes greater than 1:48 [2.08%].” The 1991 ADA Standards for this requirement are similar.

SUMMARY: Accessible parking spaces and access aisles must be mostly level and at the same level/elevation for the full length of the space. Curb ramps are not allowed to project into the accessible parking space or access aisle.
