3 ADA Parking Sign Mistakes That Could Cost California Businesses $4,000 Per Visit

Parking-related ADA violations — non-compliant spaces, missing signage, access aisle deficiencies — accounted for more than 30% of California ADA litigation in 2024. It’s the single most litigated category in the state. And the most frustrating part: the violations are almost always minor, technical, and cheap to fix. A missing sign. A faded stripe. A post at the wrong height. Under California’s Unruh Civil Rights Act, each instance carries $4,000 minimum in statutory damages per visit, plus attorney fees.

Here are the three parking sign mistakes California businesses get sued for most often — and what to do about each one.

Mistake 1: Missing or Non-Compliant Van-Accessible Sign

Federal ADA (Section 502.6) and California Title 24 both require that van-accessible parking spaces be identified with a sign that reads “Van Accessible.” This is in addition to the standard ISA (International Symbol of Accessibility) sign. Many property owners have the ISA sign installed but omit the “Van Accessible” designation — a separate, distinct violation.

California also requires that accessible parking signs include the statement “Minimum Fine $250” per the California Vehicle Code. Signs that display only the ISA without the fine language are non-compliant in California — again, a state-specific requirement that goes beyond federal ADA.

Additionally, accessible parking signs must be mounted at least 60 inches above the finished grade to the bottom of the lowest sign. Signs mounted on low posts or attached to curbs at street level are non-compliant. The sign must be visible even when a vehicle is parked in the space.

Fix it: Every accessible parking space needs a sign package that includes: ISA symbol, “Van Accessible” designation (on applicable spaces), “Minimum Fine $250″ language, mounted 60” minimum above grade. Our team installs California-compliant ADA parking sign packages with proper post height, hardware, and documentation.

Mistake 2: No “No Parking” Marking on the Access Aisle

Every accessible parking space requires an adjacent access aisle — the hatched or striped area alongside the space that allows wheelchair users to deploy ramps and lifts. The access aisle must be marked with “NO PARKING” in letters at least 12″ high on the pavement surface.

This pavement marking fades, cracks, and wears over time — and once it’s no longer clearly legible, the access aisle is technically non-compliant. Property owners often repave or re-stripe parking lots and omit or under-scale the “NO PARKING” text. Serial plaintiffs photograph faded markings as evidence.

California also requires that the access aisle be at least 8 feet wide (or 5 feet for standard accessible spaces where the van space access aisle is shared) and that it connects to an accessible route to the building entrance. A properly marked aisle that leads to a curb without a curb cut is still a violation.

Fix it: Schedule a parking lot accessibility review whenever you re-stripe or repave. Pair it with a check of the accessible route from the parking area to your entrance. Our site assessment team documents the full accessible path from parking to door.

Mistake 3: Wrong Number of Accessible Spaces (or Wrongly Signed Existing Ones)

ADA requires a minimum number of accessible parking spaces based on total lot size. As a business expands, adds vehicles, or re-configures its lot, the required number of accessible spaces changes — and many properties fall out of ratio without realizing it. California follows the same federal scoping table but adds specific requirements for medical facilities, which require higher ratios of van-accessible spaces.

A common scenario: a business adds parking spaces during a renovation, crosses a threshold in the scoping table, and is now required to have an additional accessible space — but hasn’t added one. The existing accessible spaces remain compliant, but the total count is insufficient.

Even where the count is correct, spaces are often in the wrong location. ADA requires accessible spaces to be on the shortest accessible route from the parking area to the accessible building entrance. A space technically counted as accessible but located far from the entrance — or not connected by an accessible route — is still a violation.

Fix it: Verify your required count against current ADA scoping tables whenever your lot changes. If you’ve expanded recently, a quick count check could prevent a five-figure exposure. Contact us for a parking compliance assessment.

What a Parking Sign Lawsuit Actually Costs in California

Here’s a realistic cost breakdown for a California parking ADA claim with three violations and two plaintiff visits:

Statutory damages: $4,000 × 3 violations × 2 visits = $24,000
Plaintiff attorney fees: $15,000–$25,000
Your defense attorney: $5,000–$15,000
Remediation (signs, striping, accessible route): $1,000–$3,000
Total exposure: $45,000–$67,000

The remediation — the signs and striping that would have fixed the problem — is the smallest line item. Proactive compliance is unambiguously the better investment.

Frequently Asked Questions About ADA Parking Signs in California

How many accessible parking spaces does California require?

California follows the federal ADA scoping table: 1 accessible space per 1–25 total spaces; 2 per 26–50; 3 per 51–75; 4 per 76–100; and so on. One of every six accessible spaces (minimum one) must be van-accessible. Medical facilities have higher requirements. California also requires that 1 in every 4 accessible spaces be van-accessible for medical outpatient facilities.

What must California ADA parking signs display?

California ADA parking signs must include: the International Symbol of Accessibility (ISA), “Van Accessible” designation for van-accessible spaces, and the statement “Minimum Fine $250” per the California Vehicle Code. Signs must be mounted at least 60 inches above finished grade to the bottom of the lowest sign and must be visible when a vehicle is parked in the space.

Can a private parking lot be cited for ADA violations?

Yes. Private parking lots serving places of public accommodation (retail stores, restaurants, offices, medical facilities, etc.) are subject to ADA Title III requirements. In California, the Unruh Civil Rights Act applies to all business establishments — there is no exemption for private lots.

Does repainting or restriping a parking lot trigger ADA compliance requirements?

Generally yes. In California, alterations to a facility trigger requirements to bring the altered area (and often the accessible path of travel to the altered area) into compliance with current ADA and Title 24 standards. Re-striping a parking lot is considered an alteration. This is a common trigger for parking ADA compliance reviews.

What is the difference between an accessible space and a van-accessible space?

A standard accessible space requires an 8-foot-wide space with a 5-foot access aisle. A van-accessible space requires a 9-foot-wide space with an 8-foot access aisle (or alternatively, a 11-foot space with a 5-foot aisle on the passenger side). The extra width accommodates the side-deployment ramps and lifts used by many wheelchair van users. Van-accessible spaces must be specifically designated with the “Van Accessible” sign.
