2026 ADA Lawsuit Survival Guide for Property Managers | Part 3 of 4
Last week we covered the six most common ADA compliance failures driving lawsuits across California right now.
This week is about something more dangerous.
How a parking lot improvement project can accidentally create new ADA violations overnight.
Not because anyone ignored the property. Not because the original construction was wrong. But because resurfacing changes geometry. And geometry is what ADA lawsuits are built on.
If you manage commercial properties, sit on an HOA board, run facilities, or own a small retail center, this might be the most important concept to understand before you approve any paving project in 2026.
Because many of the properties getting sued today were resurfaced recently. They looked brand new. And they were still non-compliant.
The Mistake Almost Everyone Makes
Most resurfacing projects get treated like maintenance. Mill the asphalt. Install a new lift. Re-stripe. Move on.
Sounds simple. It is not.
Parking lots are not just surfaces. They are drainage systems. Slope systems. Accessibility systems. The second asphalt elevations change, cross slopes shift. Water flow redirects. Access aisle tolerances tighten. Sidewalk transitions move. Ramp landings change height. Detectable warnings shift elevation. Accessible routes lose continuity.
This is why resurfacing projects create so many ADA problems. And why the cheapest paving proposal is often the most expensive long-term decision a property manager can make.
Why This Matters If You Manage Commercial Properties
Dana manages a 14-property commercial portfolio across the East Bay. Last year she got three bids for a retail center parking lot. One contractor said "simple overlay." Another said "concrete corrections required." The third recommended ADA upgrades and drainage improvements.
Dana's first instinct was that somebody was upselling.
But here is the real difference. Some contractors are pricing asphalt. Others are pricing risk reduction. Those are not the same project.
The overlay-only bid came in at $38,000. The bid that included ADA corrections and drainage work was $67,000. Dana went with the overlay. Eight months later her ownership group spent $41,000 on emergency concrete corrections after a tenant's customer filed an accessibility complaint. Total cost: $79,000. Plus the headache.
If ADA conditions get ignored during resurfacing, the property manager is usually the person answering questions when problems show up later. Not the paving contractor. Not the striping company. The PM.
Three Hidden Overlay Problems We See Constantly
Asphalt-to-concrete lips. This is one of the easiest ADA violations for a plaintiff to document. A property overlays the asphalt but leaves the surrounding sidewalks and curb ramps untouched. Now the new asphalt sits higher than the existing concrete. You get abrupt vertical transitions. Wheelchair access problems. Water trapping near access aisles. Trip hazards at sidewalk edges. Cracking where asphalt pulls away from concrete.
This is extremely common on HOA properties with aging flatwork and multiple historical overlays. The dangerous part is that many of these transitions look acceptable visually. But ADA lawsuits are not based on appearance. They are based on measurements.
ADA stalls quietly moving out of compliance. Accessible parking stalls and access aisles must stay at 2 percent slope or less in every direction. A relatively small overlay can push an already borderline stall beyond tolerance. This usually happens when existing grades were already marginal, settlement existed underneath the stall, or crews simply followed existing grades without checking. Fresh striping creates the illusion everything is compliant. A digital level tells a completely different story.
This is exactly why newly resurfaced parking lots still end up in lawsuits. The surface looks perfect. The numbers do not pass.
Water starts flowing through ADA areas. This one gets overlooked constantly. Parking lots are engineered to move water somewhere. The moment grades change, drainage changes too. We regularly see resurfacing projects accidentally redirect water through access aisles, across accessible routes, into curb ramp landings, and toward building entrances. At first the PM just notices puddles. But ponding eventually creates settlement, surface deformation, cracking, slip hazards, and base deterioration underneath the accessible areas. One resurfacing project has now unintentionally created multiple ADA exposure points.
Why HOA Communities Are Especially Vulnerable
Carol manages four HOA communities across Contra Costa County. Pavement projects are consistently the largest and most debated reserve expense across all of them.
That creates enormous pressure to choose the "reasonable" bid.
The problem is that volunteer HOA boards usually see resurfacing as cosmetic maintenance. Not infrastructure risk management. So when one proposal includes concrete replacement, drainage corrections, ADA improvements, and regrading work, and another proposal simply says "overlay and stripe," the cheaper proposal wins the vote almost every time.
I have seen this play out dozens of times. The board saves $25,000 to $40,000 on the front end. Then three years later they are paying for corrective concrete work, emergency re-striping, additional mobilizations, and resident complaints that eat up more than they saved. Some boards end up spending 30 to 50 percent more than the comprehensive bid would have cost originally.
The surface was improved. The geometry underneath was not. That is why so many HOA roads fail again only a few years after resurfacing.
Industrial Facilities Have a Different Problem
Marcus runs facilities for a distribution center in Hayward. His resurfacing failures become operational risks much faster than anything in retail or HOA.
Heavy truck traffic magnifies every drainage and settlement problem. A resurfaced truck court with poor drainage can lead to rutting within months. Water intrusion accelerates base failure. Forklift instability creates safety exposure. Dock apron settlement disrupts operations.
Unlike a retail center, industrial pavement failures directly impact business continuity. A truck court that ponds after resurfacing is not just a liability issue. It is an operational disruption that costs money every day it goes unresolved.
This is why industrial resurfacing projects should never be evaluated strictly as paving projects. They are operational infrastructure projects.
The "Looks Great" Trap
This is one of the biggest misunderstandings in the industry.
A parking lot can look beautiful and still be completely non-compliant.
Fresh black asphalt hides problems. New striping creates confidence. Boards feel relieved because the property "finally looks fixed." But compliance is not judged visually. It is judged with digital levels, straightedges, tape measures, drainage flow analysis, and transition measurements.
That is the disconnect. The board sees a successful project. The plaintiff sees measurable violations.
ADA Is Built With Grading, Not Graphics
This is probably the single most important sentence in this entire series.
Many resurfacing projects incorrectly assume the striping contractor "handles ADA." Striping does not create compliance. Geometry creates compliance. If the underlying grades are wrong, perfectly painted ADA stalls do not matter. A $1,200 striping job cannot fix a $15,000 grading problem.
What Should Happen Before Any Overlay Project
Before approving resurfacing, every property manager should require an ADA-focused pre-overlay walkthrough. Not afterward. Before. Because once paving starts, correcting geometry becomes dramatically more expensive.
That walkthrough should evaluate existing stall slopes, drainage flow, ponding locations, sidewalk transitions, access aisle geometry, ramp elevations, settlement areas, asphalt-to-concrete transitions, existing trip hazards, and detectable warning conditions.
This allows the project team to identify where concrete corrections, drainage modifications, grinding, regrading, or ramp reconstruction must happen before asphalt is installed.
That is how resurfacing projects avoid accidentally creating new liability.
Why the Lowest Bid Often Becomes the Most Expensive
Tom owns a small strip center in Walnut Creek. Every paving dollar feels personal. That is understandable.
But one of the biggest mistakes owners make is comparing overlay proposals strictly by asphalt quantity. Many low bids exclude the expensive but critical items. No ADA verification. No drainage corrections. No concrete transitions. No regrading. No compliance surveying.
On paper the cheap bid wins. Three years later Tom is paying for corrective work, attorney fees, settlements, emergency mobilizations, and tenant complaints. I have seen $45,000 "savings" on an overlay turn into $90,000 in total project cost once the corrections, legal exposure, and second mobilization get added up.
The cheapest proposal often becomes the most expensive outcome.
One Thing You Can Do This Week
If your property has been resurfaced within the last few years, walk your ADA areas again. Check parking stall slopes. Look for access aisle ponding. Feel for asphalt-to-concrete lips with your foot. Look at sidewalk transitions. Note where water collects now that did not collect before.
You may discover issues that were unintentionally created during resurfacing.
And if you are planning a paving project this year, make ADA review part of the project before asphalt work begins. Not after. Because once paving starts, geometry becomes expensive to fix.
Final Thought
Most ADA lawsuits are not caused by catastrophic failures. They are caused by small details nobody measured. And resurfacing projects create more of those details than almost any other exterior improvement.
Today's property managers are no longer just maintaining pavement. They are managing liability hidden inside the pavement itself.
Stay ahead of the plaintiffs.
Next week in Part 4 of our ADA Lawsuit Survival Guide, we'll cover how property managers should document ADA issues, contractor recommendations, and deferred repairs to better protect themselves when problems arise.
