Every year, thousands of businesses receive ADA complaints—and most of them are triggered by simple parking lot mistakes that go unnoticed for years. In 2025, ADA enforcement has become even stricter, especially in California, Arizona, Texas, and Florida.
The good news?
Almost all ADA parking lot violations can be prevented with routine inspections, correct measurements, and basic maintenance.
Here are the 5 ADA mistakes that expose business owners to lawsuits—and the fixes you can implement today.
1. Incorrect Slopes and Ramp Grades
More than 60% of ADA non-compliance issues come from slopes that are too steep or improperly graded.
Common Violations
Access aisles above 2% slope
Parking stalls sloping into drainage areas
Ramps steeper than the 1:12 ADA ratio
No flat landing at the top of a ramp
How to Fix It
Measure slopes with a digital ADA inclinometer
Regrade or mill areas exceeding 2%
Add or correct curb ramps with proper landings
Repaint all lines after slope correction
Incorrect slopes are one of the easiest violations for plaintiffs to spot.
2. Faded or Missing Striping
Striping fades quickly due to traffic, sunlight, and weather. When accessible markings are unclear, your property immediately becomes a lawsuit target.
Common Violations
Faded wheelchair symbols
Missing or unclear access aisles
Incorrect colors or spacing
Worn-out cross-hatching
How to Fix It
Restripe every 24–36 months
Use high-durability traffic paint
Refresh cross-hatching at 6-inch width
Reapply ADA symbols using reflective, high-contrast paint
Fresh striping is one of the cheapest ways to stay compliant.
3. Incorrect Signage Height or Missing Signs
ADA parking requires precise signage placement. Plaintiffs often check signage before anything else.
Common Violations
Bottom of sign lower than 60 inches
Missing “Van Accessible” signs
Temporary or non-permanent sign posts
Signs placed too far from stall center
How to Fix It
Mount signs at 60–66 inches (bottom height)
Use reflective ADA-approved signs
Add “Van Accessible” signs where required
Install permanent posts only
Signage is inexpensive to fix—and expensive to ignore.
4. Improper Van-Accessible Space Dimensions
Many businesses unknowingly size van-accessible stalls incorrectly, making them immediate lawsuit risks.
Common Violations
Access aisle narrower than 8 feet
Stall width less than 96–132 inches
Missing cross-hatched aisle
Incorrect placement of the aisle
How to Fix It
Verify stall width matches ADA specs
Confirm aisles are at least 8 feet wide
Place the aisle on the passenger side
Repaint layout following proper ADA design
Van spaces are the most frequently cited ADA stall violation.
5. Missing or Non-Compliant Path of Travel
ADA requires a clear, safe, and unobstructed route from the accessible stall to the business entrance.
Common Violations
No ramp from parking lot to sidewalk
Obstacles blocking the route
Cracked or uneven concrete
Missing truncated domes
How to Fix It
Add ADA-compliant curb ramps
Maintain a 36-inch minimum walkway width
Repair broken or lifted concrete sections
Install truncated domes at crossing points
A non-compliant path of travel is one of the fastest ways to receive a complaint.
How Often Should You Inspect Your ADA Parking Lot?
At minimum: once every 12 months.
But you should inspect immediately after:
New construction
Repaving or sealcoating
Heavy rain or flooding
Any major property update
Proactive maintenance costs far less than a lawsuit.
