If you own or manage a commercial property in Texas, accessible parking is not optional. Two overlapping sets of rules govern your lot: the federal Americans with Disabilities Act (ADA) Standards for Accessible Design and the Texas Accessibility Standards (TAS) enforced by the Texas Department of Licensing and Regulation (TDLR). Where TAS is stricter than federal ADA, Texas law controls, and in several important areas, TAS does go further. Getting this wrong exposes you to DOJ complaints, TDLR enforcement actions, private ADA lawsuits, and fines up to $1,000 per day per violation under Texas law. Below is the complete breakdown for 2026.
Important: This guide covers the most common requirements for commercial surface lots in Texas. Medical facilities, outpatient clinics, and rehabilitation centers have additional ratio rules. Always verify with TDLR or a qualified consultant for complex projects.
How many accessible spaces does your lot need?
Both ADA and TAS use the same minimum ratio table, based on the total number of parking spaces in your lot. This is the minimum, not a suggestion.
| Total Spaces in Lot | Minimum Accessible Spaces |
|---|---|
| 1 to 25 | 1 |
| 26 to 50 | 2 |
| 51 to 75 | 3 |
| 76 to 100 | 4 |
| 101 to 150 | 5 |
| 151 to 200 | 6 |
| 201 to 300 | 7 |
| 301 to 400 | 8 |
| 401 to 500 | 9 |
| 501 to 1,000 | 2% of total |
| 1,001+ | 20 + 1 per each 100 over 1,000 |

A common DFW scenario: a strip center with 120 total stalls needs a minimum of 5 accessible spaces. If the lot has multiple buildings with separate entrances, accessible spaces must be distributed to serve each entrance, not clustered in one corner.
Van-accessible space requirements
Federal ADA requires that at least one out of every six accessible spaces (or fraction thereof) be van-accessible. For a lot with 5 accessible spaces, that means at least 1 must be van-accessible. Van-accessible spaces have specific dimensional requirements:
- Stall width: minimum 132 inches (11 feet) with a 60-inch (5-foot) access aisle, OR a standard 96-inch (8-foot) stall with a 96-inch (8-foot) access aisle.
- Vertical clearance: minimum 98 inches (8 feet 2 inches) at the space, access aisle, and along the vehicle route to and from the space.
- Signage: must include the International Symbol of Accessibility AND a "Van Accessible" designation.
In practice, most DFW lot operators use the 11-foot stall plus 5-foot aisle configuration because it fits standard lot geometries better. The 8+8 configuration works well where lots have extra width to spare.
Access aisle dimensions
Every accessible space must have an adjacent access aisle, the striped, hatched area where wheelchair ramps deploy and mobility devices have room to operate. Here are the rules:
- Standard accessible spaces: 60-inch (5-foot) minimum access aisle width.
- Van-accessible spaces: 60-inch minimum if using an 11-foot-wide stall; 96-inch minimum if using a standard 8-foot stall.
- Length: the access aisle must run the full length of the parking space, typically 18 to 20 feet.
- Slope: maximum 1:48 (approximately 2%) in all directions. This is critical in DFW, where lots built on Texas clay often settle unevenly over time.
- Markings: diagonal stripes at approximately 36-inch intervals, clearly contrasting with the pavement.
Two adjacent accessible spaces can share a single access aisle between them, which is the most space-efficient layout. We detail this in our ADA compliance service page.
Signage specifications
Both ADA and TAS have detailed signage rules, and Texas adds several requirements that go beyond the federal standard.
Federal ADA signage
- Each accessible space must have a sign displaying the International Symbol of Accessibility (ISA).
- Signs must be mounted so the bottom edge is at least 60 inches above the ground, ensuring visibility when a vehicle is parked in the space.
- Van-accessible spaces need an additional "Van Accessible" marker.
Texas-specific signage (TAS & Transportation Code)
This is where Texas gets stricter. Under Texas Transportation Code Section 681.011 and TAS rules:
- Signs must state the maximum fine for illegal parking in an accessible space. As of 2026, fines range from $500 to $1,250 per offense.
- The sign must include a notice that the space is reserved for persons with disabilities.
- Signs must be reflective and visible at night.
- In lots with four or more accessible spaces, at least one sign must include contact information for reporting violations, or reference the towing authority.
Many DFW properties we inspect fail on signage alone, often because signs were mounted too low, lack the fine amount, or have faded to illegibility. Replacing non-compliant signs is one of the fastest, lowest-cost ways to reduce your legal exposure.
TAS vs. ADA: where Texas goes further
Property owners sometimes assume that meeting federal ADA is enough. In Texas, that assumption can cost you. Here are the key areas where TAS imposes stricter or additional requirements:
- TDLR registration: any construction or alteration project affecting accessibility on a commercial property must be registered with TDLR and inspected. This includes restriping that changes the accessible parking layout.
- Professional oversight: TAS requires that accessibility elements be designed or reviewed by a Registered Accessibility Specialist (RAS) on projects over a certain threshold.
- Signage content: Texas requires fine amounts and specific language on signs that federal ADA does not mandate.
- Enforcement mechanism: TDLR can independently investigate complaints and levy fines up to $1,000 per day per violation, separate from any federal DOJ action or private ADA lawsuit.
- Curb ramp requirements: TAS has specific curb ramp slope and landing requirements that, in some configurations, are more prescriptive than federal standards.
The practical takeaway for DFW property managers: always design to TAS, because if you meet TAS, you automatically meet or exceed federal ADA. The reverse is not always true.
Penalties and enforcement in 2026
Non-compliance carries real financial consequences from multiple directions:
- TDLR administrative penalties: up to $1,000 per day per violation for failure to meet TAS.
- Individual parking fines: $500 to $1,250 per offense for illegal use of an accessible space (Texas Transportation Code 681.011).
- Private ADA lawsuits: under federal law, a plaintiff can seek injunctive relief and attorney's fees. In practice, many DFW businesses face demand letters seeking $5,000-$15,000 or more in settlement, plus the cost of remediation.
- DOJ enforcement: the Department of Justice can investigate and pursue civil penalties, especially when there is a pattern of non-compliance.
- Insurance and liability: a non-compliant lot that leads to an injury creates significant premises liability exposure.
We have seen DFW property owners spend more on a single ADA lawsuit settlement than it would have cost to bring their entire lot into compliance. Prevention is always cheaper.
Common violations we find in DFW lots
After inspecting hundreds of commercial lots across Dallas, Fort Worth, Arlington, and surrounding cities, these are the violations we encounter most frequently:
- Access aisle too narrow or missing entirely -- the hatched area is often the first thing to fade, and many lots never had proper aisles to begin with.
- Insufficient number of accessible spaces -- lots that have been expanded or reconfigured without updating the accessible count.
- No van-accessible space -- a lot with two accessible spaces that are both standard-width violates the one-in-six van requirement.
- Signs mounted too low or missing fine language -- Texas-specific requirements are frequently overlooked.
- Excessive slope on access aisles -- pavement settling on DFW clay soils pushes slopes beyond the 2% maximum over time.
- Accessible spaces not on the shortest accessible route -- spaces should be closest to the accessible entrance, not just convenient for the paint crew.
- Faded or illegible pavement markings -- the ISA symbol and access aisle stripes must be clearly visible. A faded marking is treated as a missing marking.
If any of these sound familiar, an ADA compliance assessment is the fastest way to identify and prioritize fixes before a complaint is filed.
2026 updates and what's ahead
While there are no sweeping federal ADA changes taking effect in 2026, several trends are affecting DFW properties now:
- EV charging accessibility: the DOJ and TDLR are increasingly scrutinizing accessible routes to EV charging stations. If you are adding chargers, accessible spaces serving those stations must meet all ADA/TAS requirements, including van-accessible clearance heights that accommodate charger-equipped spaces.
- Increased private enforcement: ADA lawsuit filings in the Northern District of Texas have increased steadily. Serial plaintiffs and their attorneys actively survey DFW commercial lots, particularly retail centers, medical offices, and restaurants.
- TDLR inspection backlog: as construction activity remains high across DFW, TDLR inspection timelines have lengthened. Plan ahead and register projects early to avoid delays.
- Stricter municipal overlay: some DFW cities, including Frisco and Plano, are adopting local accessibility ordinances that add requirements beyond state TAS, particularly around detectable warning surfaces and pedestrian routes within parking lots.
How to bring your DFW lot into compliance
The process is simpler and more affordable than most property owners expect:
- Audit: We measure every accessible element, stall widths, aisle widths, slopes, signage height, pavement condition, route of travel, and document what needs to change.
- Plan: We provide a prioritized remediation plan with clear costs, starting with the highest-risk violations.
- Execute: Our crew handles striping, signage installation, access aisle marking, and pavement repairs. For lots that also need surface work, we coordinate sealcoating and asphalt repairs in a single mobilization to save time and money.
- Document: You receive before-and-after photos and a compliance summary for your records, useful if a complaint is ever filed.
We serve the entire DFW Metroplex, including Plano, Irving, Frisco, Garland, McKinney, and every city on our service-area map.
