Your parking lot is the very first thing visitors see, and it’s also where they decide how easy it will be to gain access to your space. But here’s the question: is your parking lot ADA-compliant? Meeting ADA standards, aside from complying with the law, is one of the most important ways to help people with disabilities feel welcome and safe. Local authorities expect the minimum accessibility requirements to be met, and with Oklahoma Parking Lot Services on your side, the process immediately becomes much simpler.
What Does It Mean to Be ADA (Americans with Disabilities Act) Compliant?
Being ADA compliant means following the ADA guidelines and accessible design standards that cover every detail of how parking facilities must serve the public. The law is clear: accessible parking spaces must be provided in any lot that serves the public, from residential facilities to large parking garages.
In practical terms, ADA compliance involves:
- Providing the correct minimum number of accessible spaces based on the total parking spaces provided in each facility.
- Making sure those spaces are the right size, with the correct access aisles, slope, and vertical clearance.
- Placing spaces on the shortest accessible route to an accessible entrance or building entrance.
- Adding proper signage, including the International Symbol of Accessibility, to clearly mark each space.
Without these elements, even one accessible parking space that’s designed incorrectly can keep someone from using it.
Necessary Features of ADA-Compliant Parking Lots
The requirements for ADA compliance are designed to give people with disabilities the same safe, functional experience as everyone else. From the minimum accessibility requirements to the way van accessible spaces are laid out, there’s a clear list of features that every compliant lot must include.
Minimum Number of Accessible Parking Spaces Required
The ADA spells out exactly how many accessible spaces are required for different lot sizes. You can’t combine counts from separate parking facilities, as each one has to comply individually.
Below, you’ll find a breakdown of the minimum number of accessible spaces:
| Total Parking Spaces | Min. Accessible Parking Spaces Required |
|---|---|
| 1–25 | 1 |
| 26–50 | 2 |
| 51–75 | 3 |
| 76–100 | 4 |
| 101–150 | 5 |
| 151–200 | 6 |
| 201–300 | 7 |
| 301–400 | 8 |
| 401–500 | 9 |
| 501–1,000 | 2% of the total parking spaces |
| 1,001+ | 20 + 1 for each 100, or fraction thereof, over 1,000 |
Ultimately, at least one space has to be a van accessible parking space, no matter how small the lot.
Van Accessible Spaces
Van spaces serve people using lifts or larger mobility devices, which is why van accessible spaces come with unique requirements.
- Width: 132 inches with a 60-inch aisle, or 96 inches with a 96-inch aisle. Either layout requires one access aisle.
- Vertical clearance: A van accessible space must have 98 inches of clearance for the space, the adjacent access aisle, and the vehicle route.
- Signage: The International Symbol of Accessibility plus “Van Accessible” mounted at least 60 inches above the ground.
At least one in six accessible parking spaces (fraction thereof) must be van accessible. That’s a hard rule across all parking facilities.
Parking Space and Access Aisle Dimensions
ADA compliance is specific about spaces and access aisles:
- Standard car accessible spaces: at least 96 inches wide, with a 60-inch aisle.
- Each space needs its own aisle, or two spaces can share one center aisle.
- Aisles must be level (slope not more than 1.48 or 2.08% in all directions), clearly striped, and placed beside the space. Striping discourages parking in aisles.
- Surfaces must be firm, stable, and slip-resistant. A broken parking surface puts you out of compliance.
- Must have the International Symbol of Accessibility plus “Van Accessible” mounted at least 60 inches above the ground.
These measurements may seem minor, but they make the difference between someone being able to exit their car with mobility devices versus being blocked in.
Location and Accessibility Routes
Accessible spaces must connect to an accessible route leading directly to the accessible entrances of a building. That means:
- No stairs or curbs in the path.
- Proper curb ramps where level changes exist.
- Locating accessible parking closest to building entrance points or visitor parking spaces.
Signage Requirements
Every accessible parking spot must be marked with signage that includes the international symbol of accessibility.
- Van spaces must also say “Van Accessible.”
- Signs must be at least 60 inches high (measured from the ground to the bottom of the sign) to stay visible.
- Painted ground symbols alone don’t count. They can supplement, but they don’t replace mounted signs.
If you have four or fewer spaces in the entire lot, signage technically isn’t required. But in practice, designating accessible parking with signs avoids confusion.
Special Considerations for Different Facilities
If you own or manage property in Oklahoma, it’s worth knowing how the rules shift depending on the type of facility you operate. This section breaks down those differences so you can see how the standards apply to your situation.
Medical Facilities
Medical facilities have higher requirements. For hospital outpatient facilities, 10% of all patient and visitor parking must be accessible. That means if you have 100 spaces, at least 10 must be accessible.
Rehabilitation Facilities and Outpatient Physical Therapy Clinics
For rehabilitation facilities and outpatient physical therapy facilities, the number is even higher: 20% of patient and visitor parking must be accessible.
Parking Structures and Garages
Parking garages or any parking structure have added challenges. The big issue is vertical clearance, wherein you need at least 98 inches in any van accessible parking space and along its travel route.
If multiple levels have accessible entrances, accessible spaces must be distributed across those levels.
Compliance for Existing Buildings and Parking Lots
The ADA doesn’t just apply to new construction. Existing buildings and older parking facilities are still expected to provide reasonable accommodations. If it’s readily achievable to add or improve accessible parking, you must do it. For example, adding accessible parking when you restripe a lot is considered achievable.
There’s also a “safe harbor” rule: if your lot met the old 1991 ADA guidelines, you don’t have to update until you make changes. But once you resurface or restripe, you must meet current ADA requirements.
Common Mistakes That Lead to Non-Compliance
From our work in OKC, here are the common slip-ups we see in parking areas:
- Miscounting the minimum number of accessible spaces
- Forgetting that accessible spaces required include van spaces
- Missing or low signage
- Slope issues in the parking surface
- Access aisles that aren’t wide enough
- Failing to create an accessible passenger loading zone near main building entrance points
- Putting accessible parking spaces too far from visitor parking or the shortest accessible route
- Not accounting for spaces reserved for law enforcement vehicles, delivery vehicles, or other delivery vehicles in lots that also serve the public
- Ignoring program access requirements for local government agencies or housing with specific dwelling units
- Overlooking impounded vehicle retrieval lots, which still require ADA compliance
How to Evaluate and Improve Your Parking Lot’s ADA Compliance
The best way to check if you have ADA spaces in the right layout is to do a full walk-through:
- Count the spaces provided and confirm the accessible parking spaces required by the ADA table
- Confirm you have van accessible spaces in the right ratio
- Measure spaces and access aisles, slopes, and parking surface conditions
- Check the accessible route to every accessible entrance
- Look at the signage and confirm every van accessible space has the right label and is mounted at the right height
