In 1990, the Americans with Disabilities Act (ADA), was implemented to ensure equitable access to public spaces for individuals who live with disabilities. As a commercial property owner, ensuring your parking lot is ADA compliant is crucial, not only to provide equal access for all people but also to avoid potential lawsuits.

While ADA compliance requirements may vary between Minnesota cities and counties, the state has overarching compliance guidelines you must adhere to. Read on to learn more about what those requirements are, so you can get a better idea of whether your parking lot is currently ADA compliant.

Accessible Parking Spaces: How Many Should Your Parking Lot Have?

Accessibility to any building begins in its parking lot. According to Minnesota ADA requirements, your parking area must have a minimum number of handicap-accessible spaces based on the total vehicle capacity of the lot.

Check out the table below to find out what your minimum number is.

151 to 200

It’s important to note that parking lots for healthcare facilities have different ADA compliance requirements. To learn more about accessibility guidelines for various healthcare facility parking lots, visit the ADA Compliance Directory.

Required Features of Accessible Parking Spaces

Aside from having the required number of accessible parking spaces in your lot, you must also ensure that those spaces have the appropriate accessibility features. Here’s what your accessible parking spaces should have:

  • Location. All accessible parking spaces must be placed so that they provide the shortest route of travel into an accessible building. If the building has multiple entrances, the accessible parking space must be located on the shortest travel route to all accessible entrances.
  • Size. All accessible parking spaces must be at least eight feet wide and clearly marked to define their width. They must also feature an eight-foot-wide adjacent aisle area next to the parking space itself. If there are two spaces next to each other, they may share access to the same aisle. Van-accessible spaces must have a minimum vertical clearance of 98 inches.
  • Signage. Every accessible parking space must feature a sign displaying the international symbol of accessibility. The sign must also contain a notice stating that violators may face fines of up to $200. Minimum sign dimensions are 12 inches by 18 inches, and the sign must be between 60 and 66 inches from the surface of the pavement. Minnesota also requires that accessible aisles feature either “No Parking” signage or “No Parking” painted on the pavement within the accessible aisle.
  • Pavement markings. Accessible parking spaces are not required to have the international symbol of accessibility marked on the pavement itself; however, this common practice is highly encouraged. All accessible aisles adjacent to accessible parking spaces must have hash markings on the pavement itself. 
  • Pavement slope. All accessible parking spaces and adjacent aisles may have a maximum slope of 1:48 or 2% in any direction. That means that for every 48 inches of horizontal pavement distance, there may be no more than 1 inch of vertical change in the pavement.

When Should You Update Your Parking Lot to Meet ADA Compliance Requirements?

If you’re planning to update your parking lot in any way — restriping, resurfacing, sealcoating, etc. — you must ensure the lot meets ADA requirements for pavement markings, accessible parking space dimensions, and accessibility signage.

If you’re reconstructing or resurfacing the asphalt, you’ll also need to ensure the pavement slope of accessible spaces meets ADA requirements.
