ADA Parking Requirements in Texas
How accessible parking works in Texas: the count and stall sizes follow the federal standard, but the Texas Accessibility Standards add pavement markings, a warning sign, and a registration step most contractors miss.
Updated July 2026
TL;DR
Texas follows the federal count and stall dimensions through the Texas Accessibility Standards, so the number of accessible spaces and their sizes are the same as federal. The Texas-specific parts are a 2020 rule that adds a painted symbol, NO PARKING in the access aisle, and a fine-and-towing warning sign, plus a TDLR registration and review requirement for projects of $50,000 or more.

The Texas Accessibility Standards, or TAS, are administered by the Texas Department of Licensing and Regulation under the state Architectural Barriers Act. TAS mirrors the federal 2010 ADA Standards for the accessible-space count, the stall and access-aisle dimensions, and the one-in-six van ratio. If you know the federal numbers, you know the Texas numbers.
That means a car accessible space is at least 8 feet wide with a 5-foot access aisle, a van space is 11 feet wide with a 5-foot aisle or 8 feet wide with an 8-foot aisle, the surface slope stays within 1 in 48 in all directions, and the count follows the federal table below.
| 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 1000 | 2 percent of total |
| 1001 and over | 20, plus 1 per 100 over 1000 |
The Texas Pavement-Marking Rule
This is where Texas adds to the federal baseline. A 2020 TDLR rule change, which applies to newer and altered lots rather than retroactively to every existing one, requires more than the post-mounted sign:
- Painted symbol. The International Symbol of Accessibility painted on the pavement of the space in a contrasting color, in addition to the mounted sign.
- NO PARKING in the aisle. The words NO PARKING painted in the access aisle in letters at least 12 inches high with a 2-inch stroke, to keep the aisle clear.
- Warning sign. A sign stating at minimum that violators are subject to fine and towing, in letters at least 1 inch high, mounted 48 to 80 inches above the ground and no more than 8 inches below the main accessible-parking sign.
The $50,000 Registration Step
Texas adds an administrative requirement contractors and owners overlook. A construction or renovation project with an estimated cost of $50,000 or more must be registered with TDLR through its online system, and the plans must go through a Registered Accessibility Specialist review, with an inspection after completion. Restriping and small maintenance usually fall below the threshold, but a full lot reconstruction can cross it. Budget the registration and review time into the schedule when the project is large.
Worked Example: 120-Space Texas Lot
Scenario: a 120-space retail lot in Texas getting a full re-layout.
- Accessible spaces required: 5 (the 101 to 150 row of the federal table)
- Van-accessible among them: at least 1 (one per six accessible spaces, rounded up)
- Texas markings: painted symbol in each space, NO PARKING in each access aisle, warning sign under each main sign
- If the job is $50,000 or more: register with TDLR and route the plans through a Registered Accessibility Specialist before you finish.

Are Texas ADA parking requirements different from federal?
The count and stall dimensions are the same; the Texas Accessibility Standards adopt the federal 2010 ADA numbers. Texas adds its own layer: a 2020 rule requiring a painted accessibility symbol, NO PARKING painted in the access aisle, and a fine-and-towing warning sign, plus a TDLR registration and Registered Accessibility Specialist review for projects of $50,000 or more.
How many accessible parking spaces does Texas require?
The same as federal law: 1 space for lots up to 25, scaling up to 9 for 401 to 500 spaces, then 2 percent for 501 to 1000, and 20 plus 1 per 100 over 1000 above that. At least one in every six accessible spaces must be van-accessible. Texas does not require more spaces than the federal table.
What are the Texas access-aisle marking requirements?
Under the 2020 TDLR rule, the access aisle must have NO PARKING painted in it in letters at least 12 inches high with a 2-inch stroke, and each accessible space must have the International Symbol of Accessibility painted on the pavement in a contrasting color. A warning sign about fines and towing is also required near the main sign.
When does a Texas parking project need TDLR registration?
When the estimated construction cost is $50,000 or more. That project must be registered with TDLR through its online system and reviewed by a Registered Accessibility Specialist, with a post-construction inspection. Routine restriping usually falls below the threshold, but a full reconstruction can exceed it, so confirm the project value early.
