Accessibility is more than a design feature it’s a legal and ethical obligation. In Texas, the Texas Accessibility Standards (TAS) ensure that public buildings are accessible to people of all abilities. These standards are enforced by the Texas Department of Licensing and Regulation (TDLR) and closely mirror the Americans with Disabilities Act (ADA), with additional state-specific requirements.
For contractors, TAS compliance isn’t optional. Any commercial construction project with an estimated cost of $50,000 or more must be registered with TDLR and reviewed by a Registered Accessibility Specialist (RAS). This means budgeting not only for design and construction elements like ramps and signage, but also for administrative tasks like registration, plan review, and final inspection.
Failing to comply with TAS can result in costly delays, fines, and even legal action. In this guide, we’ll break down the key components of TAS compliance, common pitfalls, and what contractors need to include in their estimates to stay compliant and competitive.
TAS Compliance Budget Breakdown
| TAS Requirement | Typical Cost Range | Notes |
| TDLR Project Registration | $175–$300 | Required for all projects ≥ $50,000 in value |
| RAS Plan Review | $500–$1,200+ | Conducted by a Registered Accessibility Specialist (RAS) |
| RAS Final Inspection | $500–$1,000+ | Must occur within one year of construction completion |
| Accessible Parking Spaces | $1,500–$3,000 per space | Includes striping, signage, and slope correction |
| Accessible Routes & Ramps | $100–$200 per linear foot | Includes handrails, landings, and slope compliance |
| Restroom Modifications | $3,000–$10,000+ | Includes grab bars, clearances, sinks, and turning radius |
| Signage (Braille & Tactile) | $50–$150 per sign | Required for room IDs, exits, and restrooms |
| Door Hardware & Clearances | $300–$800 per door | Includes lever handles, swing clearance, and thresholds |
| Elevator Upgrades (if needed) | $10,000–$50,000+ | Applies to multi-story buildings without compliant vertical access |
Costs vary by project type, location, and existing conditions.
When Is TAS Required?
TAS compliance is mandatory for:
-
- All commercial construction projects with an estimated cost of $50,000 or more
-
- New construction, alterations, renovations, and additions
-
- Public accommodations and commercial facilities (e.g., retail, offices, schools, hospitals)
-
- Projects submitted for permit on or after March 15, 2012
-
- Projects that affect accessibility features, such as entrances, restrooms, and parking
Contractors must register qualifying projects with TDLR within 30 days of submitting for permit and schedule a plan review and final inspection with a certified RAS.
Common TAS Compliance Mistakes
| Mistake | Consequence |
| Failing to register with TDLR | Project delays, fines, and possible legal action |
| Skipping RAS plan review | Non-compliance and rework during inspection |
| Inadequate restroom clearances | Failed inspection and costly demolition/rebuild |
| Incorrect signage placement | Accessibility violations and user confusion |
| Non-compliant slopes or landings | Trip hazards and ADA/TAS violations |
| Overlooking door swing clearance | Can block accessible routes and violate TAS |
| Using non-compliant hardware | Lever handles and thresholds must meet TAS specs |
Avoiding these pitfalls starts with accurate estimating and early coordination with design teams and accessibility specialists.
TAS Design Elements to Include in Estimates
| Feature | TAS Requirement Highlights |
| Accessible Entrances | Must be on an accessible route, with compliant door hardware and thresholds |
| Restrooms | Requires turning radius, grab bars, accessible sinks, and mirror height |
| Parking Spaces | Minimum number based on total spaces, with van-accessible dimensions |
| Ramps | Max slope of 1:12, handrails on both sides, and landings at top/bottom |
| Signage | Must include Braille and tactile lettering, mounted at correct height |
| Elevators | Required in multi-story buildings unless exempted by TAS criteria |
| Drinking Fountains | Must be accessible to both standing and seated users |
| Doorways | Minimum clear width of 32 inches, with accessible hardware |
These features should be clearly itemized in your estimate to ensure compliance and transparency.
Tips for Accurate TAS Budgeting
-
- Engage a RAS early in design to avoid rework
-
- Include TAS line items in your estimating templates
-
- Coordinate with MEP and architectural trades to ensure compliant layouts
-
- Use TAS checklists during plan review and field inspections
-
- Document all compliance efforts for closeout and legal protection
-
- Budget for potential re-inspections if initial review fails
Why TAS Compliance Pays Off
| Benefit | Impact |
| Avoids Costly Rework | Saves $10K–$100K+ on average per project |
| Speeds Up Permitting | Clear documentation accelerates approvals |
| Reduces Legal Risk | Compliance protects against lawsuits and fines |
| Improves User Experience | Accessible buildings serve more people and enhance reputation |
| Supports Public Funding | Many grants and contracts require TAS/ADA compliance |
| Enhances Marketability | Accessibility is increasingly valued by tenants and buyers |
Accessibility isn’t just about compliance it’s about inclusion, safety, and long-term value.
Final Thoughts
