Commercial sign permits in Texas.

Texas has no statewide commercial sign code for on-premise business signs. Permitting is handled by home-rule cities and counties, so the same sign can be approvable in one Texas city and prohibited in the next. Two state-level layers do apply: TxDOT licenses off-premise billboards along regulated highways, and structures in the designated coastal catastrophe counties must meet windstorm-construction standards.

What makes Texas different

  • Texas is a home-rule state with no statewide on-premise sign code, so each city — and each historic or downtown overlay — is its own rulebook rather than a single Texas standard.
  • Signs built or altered in the 14 designated seacoast catastrophe-area counties must meet Texas windstorm-construction standards and obtain a WPI-8 certificate of compliance through the Texas Department of Insurance, a wind-engineering and certification burden most inland states do not impose.
  • Houston is the largest U.S. city with no traditional zoning, so its Sign Code itself does much of the regulating, with standards keyed to the category of the street a sign faces.

Statewide rules that apply broadly

TxDOT billboard permits (off-premise)

Off-premise outdoor advertising along interstate, primary, and rural highways is licensed and permitted by TxDOT under Transportation Code Chapters 391 and 394, through the CSLAP system; amended commercial-sign regulations took effect September 1, 2024. This is separate from any local on-premise sign permit.

Coastal windstorm certification (WPI-8)

In 14 designated seacoast catastrophe-area counties, structures — including signs — built or altered since 1988 must meet windstorm-construction standards and obtain a WPI-8 certificate of compliance, administered through the Texas Department of Insurance and the Texas Windstorm Insurance Association. Coastal sign structures should be engineered and inspected accordingly.

The typical permit process

  1. 01Confirm zoning and obtain a current Certificate of Occupancy; cities like Houston and Dallas verify the C of O and that the sign name matches the business.
  2. 02Determine the sign district or overlay (Austin has a Sign District Determination tool; San Antonio and Galveston require historic-district review where applicable).
  3. 03Engage a licensed or registered sign contractor where required (Houston requires a Sign Administration license; Dallas requires contractor registration; Austin requires Outdoor Advertising Contractor registration).
  4. 04Prepare construction and site drawings; freestanding, roof, or projecting signs and signs over a height threshold typically need drawings sealed by a Texas-licensed engineer or architect showing wind-load capacity.
  5. 05Submit through the city's portal (Houston ProjectDox, Austin AB+C, Dallas) and pass plan review.
  6. 06Pull a separate electrical permit for illuminated signs, and in the coastal catastrophe counties obtain WPI-8 windstorm certification.
  7. 07Pass final inspection; city sign permits are time-limited.

Notable jurisdictions

Houston

Sign Code administered by Houston Sign Administration, applied online through ProjectDox. Standards (height, size, lighting) are keyed to the category of the street the sign faces. Houston is the largest U.S. city with no traditional zoning, so the Sign Code itself does much of the regulating, and permits generally issue to licensed sign contractors.

Dallas

Signs are governed by Chapter 51A, Article VII of the Development Code. A permit is required where sign area exceeds 20 sq ft, height exceeds 8 ft, the sign is illuminated or has motion, or it sits in a special-provision sign district. The contractor must be registered before a permit issues, and Dallas advertises roughly two business days for approval when the submittal is complete.

San Antonio

Signs are governed by Chapter 28 of the City Code, with stricter rules in historic districts under the Unified Development Code. In historic districts, pole signs and billboards are prohibited, and exterior signage requires a Certificate of Appropriateness from the Office of Historic Preservation.

Austin

Sign permits are required under the Land Development Code (Ch. 25-10). Freestanding, roof, and projecting signs need construction drawings sealed by a Texas-licensed architect or engineer. Contractors register as Outdoor Advertising Contractors, a Sign District Determination tool sets the applicable district, and applications run through the AB+C portal.

Galveston

A coastal and historic regime: most signs require a permit under the Land Development Regulations, and signs in historic districts like the Strand/Mechanic are reviewed by the Landmark Commission. As a seaward county, Galveston is in the windstorm catastrophe area, so sign structures can require WPI-8 certification.

On timelines

Timelines are highly jurisdiction-dependent and any quoted figure is an estimate. Dallas advertises roughly two business days for sign-permit approval when the submittal is complete, while plan-checked or illuminated signs in cities like Houston and Austin generally take longer. Historic-district review (San Antonio, Galveston) adds a commission cycle, and coastal windstorm inspection adds time. Confirm current processing times with the specific city department.

What adds review, time, or cost

  • Illuminated signs need a separate electrical permit and a registered electrical contractor.
  • Freestanding, projecting, or taller signs typically require drawings sealed by a Texas-licensed engineer showing wind-load capacity.
  • Historic and downtown overlays (San Antonio, Galveston) require a Certificate of Appropriateness and can prohibit pole signs and billboards outright.
  • In the coastal catastrophe counties, sign structures require WPI-8 windstorm certification through the Texas Department of Insurance.

Many Texas cities exempt small, temporary, or window signs from permitting, but the thresholds vary by city. Confirm before assuming a sign is exempt.

Questions people ask

Is there a statewide sign permit in Texas?

No. On-premise sign permitting is handled by each home-rule city or county under its own code. The state's role is limited to TxDOT billboard permits on regulated highways and, on the coast, windstorm certification.

Do coastal signs in Texas need special certification?

In the 14 designated seacoast catastrophe-area counties, sign structures generally must meet Texas windstorm-construction standards and obtain a WPI-8 certificate of compliance through the Texas Department of Insurance, in addition to the local permit.

Who can install a commercial sign in Texas?

It is city-specific. Houston requires a Sign Administration license, and Dallas and Austin require contractor registration before a permit issues. Many cities also require a current Certificate of Occupancy with a matching business name.
