The 6 Most Common ADA Compliance Failures Triggering Lawsuits in 2026 (And How to Spot Them)

2026 ADA Lawsuit Survival Guide for Property Managers | Part 2 of 4

Most ADA lawsuits don’t start with someone getting hurt.

They start with a simple photo. A parking stall that’s slightly off-level. A faded wheelchair symbol. A small lip on a sidewalk.

These technical violations are easy for serial plaintiffs to document with a phone and a digital level—and very expensive for property managers to ignore

In 2025, there were 8,667 ADA Title III federal lawsuits filed nationwide, with California leading at 3,252 cases. Under California’s Unruh Act, plaintiffs can claim a minimum of $4,000 per violation. Many cases settle around $16,000, while multi-violation claims often reach $35,000 to $55,000.

Here is the real problem: most of these issues were visible and fixable months before a claim was ever filed.

This is Article 2 of our 4-part series: “2026 ADA Lawsuit Survival Guide for Property Managers.”

Here are the six most common compliance failures driving claims right now — plus exactly how to spot them before a plaintiff does.

The Top 6 ADA Compliance Failures in 2026

According to recent California Commission on Disability Access data, parking-related violations consistently rank as the number one alleged construction-related accessibility issue.

1. Excessive Slopes in Accessible Parking Stalls and Aisles

Accessible parking spaces and access aisles must have a slope of 2 percent or less in any direction. Asphalt settlement, poor base preparation, and drainage issues often push these areas out of tolerance, making this the most common trigger for parking lot lawsuits.

For this reason, we often recommend using concrete in ADA stalls. It can be set much closer to true level during installation, which significantly reduces the likelihood of movement and future noncompliance.

2. Trip Hazards on Sidewalks and Transitions

Vertical changes greater than one quarter inch, or greater than one half inch without proper beveling, violate ADA standards. These issues are most common where asphalt meets concrete and at curb ramps. Tree roots and settlement continue to create recurring problems.

In many cases, sidewalks have multiple problem areas, not just one. That is why we recommend regularly walking your property and checking for these conditions. When issues are identified early, they can often be corrected by grinding them down using a dustless concrete grinding system at a relatively low cost.

3. Faded or Incorrect Striping and Signage

Worn wheelchair symbols, missing van accessible markings, and incorrect access aisle striping are easy to spot and even easier to document. These are some of the most common drive-by violations.

We also frequently see accessible parking that is simply not sized correctly. Standard ADA spaces should be 9 feet wide with a 5 foot access aisle. Van accessible options include either a 9 foot space with an 8 foot access aisle or a 12 foot space with a 5 foot access aisle. Stalls should have a minimum depth of 18 feet.

Signage requirements can vary depending on your location, so it is important to confirm local standards. When in doubt, have a qualified ADA professional review your layout to ensure everything is compliant.

4. Missing or Improper Truncated Domes on Curb Ramps

Detectable warnings are often missing, improperly placed, or worn down—making them one of the most commonly cited issues along exterior paths of travel. Trip hazards are also frequently created when truncated domes begin to lift or deteriorate. In addition, if your property has recently had an asphalt overlay, check for elevation mismatches where asphalt meets concrete, as even a small lip can create a non-compliant and hazardous transition.

5. Improper Access Aisles

Incorrect width, excessive slope, or improper striping can quickly lead to a violation. In California, even minor deviations are enough to trigger a claim. A common issue is access aisles becoming too narrow after restriping. Faded or missing “NO PARKING” stencils (required to be at least 12 inches tall) are another frequent citation. Misaligned aisles are also easy targets for litigants; if the access aisle doesn’t properly connect to the accessible path of travel leading to the entrance, it’s only a matter of time before it becomes a liability.

6. Poor Drainage Creating Ponding

Standing water creates slip risks and accelerates pavement settlement. Over time, this changes slopes and creates multiple violations in the same area.

Why One Issue Turns Into a Lawsuit

What starts as one issue rarely stays one issue.

A slightly out-of-tolerance slope often comes with drainage problems. That same area may also have worn striping or a transition lip. By the time a plaintiff documents it, it is not one violation. It is three or four.

I recently walked a property where the only visible issue looked like a minor slope problem. When we measured it, it failed. That same section had ponding water and a faded access aisle. That is three violations captured in a single photo.

This is why single issue cases may settle around $10,000 to $15,000, while bundled violations quickly climb into the $35,000 to $55,000 range.

Your Monthly Self Inspection Protocol

Do not rely on a quick visual check. If it looks fine, that does not mean it is compliant.

Run this walkthrough on every property:

• Use a digital level to measure every accessible stall and aisle in two directions
• Run a 4-foot straightedge across sidewalks and transitions
• Check curb ramps for proper slope, landings, and truncated domes
• Verify striping contrast and signage height (60 inches to the bottom of the sign, or 80 inches if located within an accessible path of travel).
• Inspect asphalt to concrete transitions carefully and make sure there are not any lips or large cracks where the asphalt has pulled away from the concrete
• Look for ponding after rain or irrigation

Photograph and timestamp every issue. Strong documentation has helped property managers reduce exposure and negotiate better outcomes.

Action Steps You Can Take Today

If you have any compliance questions on your property comment below with questions and post a picture and I will let you know what I see.

If you want a second set of eyes, we also provide on-site audits focused on asphalt, concrete, and ADA corrections that target these exact issues.

We are seeing these problems across HOAs and commercial properties throughout California right now.

Which of these six failures concerns you most on your properties I read every reply.
