If you manage a commercial property in Tennessee, from Nashville to Clarksville to Columbia, you’re legally required to comply with the Americans with Disabilities Act (ADA). That includes more than just ramps and doorways—your parking lot must also meet strict accessibility standards.

Failure to comply can lead to fines, lawsuits, and loss of business. Fortunately, a few simple checks can help ensure your parking lot is both safe and compliant.

Here are 5 things every property owner or facility manager should review today.

✅ 1. Correct Number of Accessible Parking Spaces

Requirement:
The ADA requires at least one accessible space for every 25 total spaces, up to 100. Beyond that, the ratio changes, and at least one of those spaces must be van-accessible.

Quick Check:
Count your total parking spaces. If you have 50, you should have at least 2 accessible stalls, one of which should be van-accessible.

Common Mistake:
Older lots often fall short on quantity or forget to designate van-accessible spots.

✅ 2. Proper Width & Access Aisles

Requirement:
Accessible spaces must be at least 8 feet wide with an adjacent access aisle that is 5 feet wide (or 8 feet for vans). These access aisles must connect to an accessible route to the building.

Quick Check:
Use a tape measure—if your access aisle is narrower than 5 feet, it’s not compliant.

Tip:
The access aisle must be striped and unobstructed, including no signs, poles, or curbs blocking entry.

✅ 3. Visible ADA Signage & Striping

Requirement:
Each accessible parking space must be clearly marked with:

• Striping showing the access aisle

• The International Symbol of Accessibility

• A sign posted at least 5 feet above ground level

Quick Check:
Is your striping faded or missing? Are your signs mounted too low or not visible?

Pro Tip:
Use thermoplastic or high-durability paint for long-lasting striping that stays visible through rain and traffic.

✅ 4. Proper Slopes & Surfaces

Requirement:
Parking spaces and access aisles must be level, with a slope no greater than 1:48 (roughly 2%) in all directions.

Quick Check:
Use a digital level or contact a paving contractor for a slope audit. If water pools in spaces, there may be compliance issues.

Bonus:
Smooth, crack-free asphalt or concrete is not just good for ADA—it improves safety and looks more professional.

✅ 5. Accessible Pathways to the Building Entrance

Requirement:
There must be a safe, accessible route from the parking space to your entrance. That includes curb ramps, clear signage, and no steps or elevation changes without compliant ramps.

Quick Check:
Follow the route from your accessible space to the door. Any stairs, broken sidewalks, or sloped pathways without handrails = noncompliance.

🚫 Bonus: Common ADA Mistakes in Parking Lots

• Faded or missing signage

• Non-striped access aisles

• Blocked accessible routes (by carts, landscaping, or delivery areas)

• Poor drainage that creates puddles or uneven surfaces

📋 Final Thoughts: Don’t Risk Non-Compliance

Ensuring ADA parking lot compliance isn’t just about following the law—it’s about creating an inclusive, accessible experience for every customer or visitor.

Regularly reviewing your lot—and partnering with an experienced paving contractor—can help you avoid risk, enhance safety, and maintain a professional image.
