ADA lawsuits are rising fast across the U.S., especially in California. Most violations come from parking lots, not from bathrooms or interior routes — and the majority are completely preventable.

This updated 2026 ADA Parking Lot Checklist will help you understand exactly what inspectors and attorneys look for when targeting non-compliant properties.

Follow this list and you’ll drastically reduce your risk of ADA claims, fines, or demand letters.

1. Required Number of ADA Stalls

The number of accessible parking spaces depends on the total number of stalls on the property:

At least one space must be van-accessible.

Most lawsuits begin because the property simply has too few ADA spaces.

---

2. Stall Dimensions (2026 Standards)

You must have:

• Standard ADA stall: 8 ft wide

• Access aisle: 5 ft wide

• Van-accessible stall: 12 ft stall OR 8 ft stall with an 8 ft access aisle

Access aisles must be clearly striped and NOT used as extra parking spaces — this is a frequent violation noted in lawsuits.

---

3. Correct Slopes and Surfacing

This is the #1 physical violation in ADA lawsuits.

All ADA spaces and access aisles must have:

• Slope ≤ 2% (1:48) in every direction

• Smooth, stable, slip-resistant paving

• No dips, cracks, ponding water, or uneven areas

Even a 3% slope is enough for a plaintiff to win a case.

Most PMs don’t know:
Attorneys come with digital slope meters and measure all four corners.

---

4. Proper Signage (Height & Wording)

Each ADA space must have:

• Reflective blue sign

• International Symbol of Accessibility

• Minimum 60 inches above ground

• “Minimum $250 Fine” text (state-dependent)

• “Van Accessible” sign where required

If signs are missing, damaged, incorrect, or installed too low → automatic violation.

---

5. Pavement Markings & Colors

Required markings include:

• Blue border around the ADA stall (California-specific)

• Cross-hatched access aisle

• White wheelchair symbol (NOT faded)

• “NO PARKING” text on the aisle (California)

Faded or incorrect striping is one of the most common reasons PMs get surprise demand letters.

---

6. Path of Travel to Entrance

The accessible route from the ADA stall must:

• Be direct and obstacle-free

• Have a slope ≤ 2% cross-slope / ≤ 5% running slope

• Have no steps, curbs, cracks, or hazards

• Lead to the primary entrance

Many lawsuits begin because the accessible route is too steep or broken — even if the stall itself was compliant.

---

7. Curb Ramps

Curb ramps must have:

• Correct slope (≤ 8.33%)

• Detectable warning surface (truncated domes)

• 36-inch minimum width

• Smooth transitions with no lip

• Proper flares

Improper curb ramps are among the most expensive ADA fixes.

---

8. Maintenance Issues That Trigger ADA Violations

Even if your lot was compliant when installed, it can fall out of compliance due to:

• Fading striping

• Cracks or potholes in ADA stalls

• Water pooling

• Heaving or sinking asphalt

• Broken or missing signage

• Re-striping done incorrectly by low-cost contractors

ADA compliance is not one-and-done — it requires ongoing maintenance.

---

9. Why ADA Lawsuits Target Parking Lots

Because they are:

• Easy to inspect

• Fast to document

• Measurable

• High-liability

• The first thing a plaintiff sees when visiting

Attorneys know that parking lots are the easiest place to find violations and force settlements.

10. How to Protect Your Property in 2026

Here’s what we recommend:

✔ Get a full ADA parking lot audit

Conducted by a professional familiar with current 2026 standards.

✔ Fix slope and surfacing first

This is where most lawsuits are won or lost.

✔ Refresh striping annually

Even small fading creates risk.

✔ Replace damaged signs immediately

A missing sign can cost you thousands.

✔ Keep records of compliance work

Document inspections, striping dates, and repairs.

Final Takeaway

ADA lawsuits won’t slow down in 2026 — but most are completely preventable.

If your parking lot isn’t marked correctly, has slopes above 2%, or lacks proper signage, you are at real risk of a claim.

A simple compliance audit can save you tens of thousands of dollars in legal fees and settlements.
