A Texas sign outside city limits is not automatically outside local regulation. Municipal sign ordinances can extend into extraterritorial jurisdiction, specific statutes grant certain counties sign powers, and TxDOT regulates covered roadside advertising. Start with the location and sign category; then identify the applicable legal route.
Inside a city: identify the municipal authority
Local Government Code section 216.901 expressly authorizes home-rule municipalities to regulate signs and billboards by charter or ordinance, subject to its limitations. That provision is specifically about home-rule municipalities. For a different form of municipality, ask the city to identify the authority and adopted ordinance it uses rather than assuming section 216.901 answers every case.
Request the city's current boundary confirmation, zoning district if applicable, adopted sign provisions, and application route. A mailing address containing the city name is insufficient evidence that the proposed sign lies inside its limits.
Outside city limits: check the current ETJ
Section 216.902 permits a municipality to extend its outdoor sign ordinance into its extraterritorial jurisdiction, or ETJ. A municipality can also step back: instead of using its own ordinance, it may let the Texas Transportation Commission regulate outdoor signs in its ETJ by filing a written notice with the commission (section 216.902(a)). Extension is something to verify, not assume. Ask whether the sign location is currently in the ETJ and whether an ordinance actually extends there.
The section contains exceptions for specified on-premises signs. It also says that an extended municipal ordinance supersedes regulations under Transportation Code chapter 394 in that territory. This is a specific statutory interaction; it is not a rule that a city permit eliminates every state requirement. Keep the ETJ determination and the sign's on-premises or off-premises classification together.
County authority requires a specific check
Texas county zoning powers should be checked against the particular grants in Local Government Code chapter 231. Its subchapters authorize regulation in specified settings, rather than supplying one general statewide county zoning scheme.
Transportation Code section 394.063 separately allows a county with a population above 3.3 million, or a county bordering one, to regulate specified aspects of on-premise signs in its unincorporated territory. The section addresses when county adoption displaces other on-premise regulations and limits its application by sign erection date. Sections 394.061–394.062 establish a different route for off-premise portable signs: a county with a population of 3.3 million or more may prohibit or regulate them in its unincorporated area, and its rule prevails over a conflicting state law or rule. If a city has extended its sign ordinance into its ETJ under section 216.902, however, that city ordinance prevails over a conflicting county portable-sign rule in that territory (section 394.062(b)). These powers refute a blanket claim that Texas counties cannot regulate signs.
Ask the county which provision applies, whether it exercised that power, and what territory and sign category the enactment covers. A statutory option is not proof that a particular county adopted a sign-permit program.
Make the TxDOT inquiry specific
TxDOT's Commercial Signs Regulatory Program administers chapter 391 for covered highways and chapter 394 for outdoor advertising along minor roads outside municipal limits. Its program page links the applicable rules, the commercial signs map, and certified-city information. Use those resources to check the road and sign category instead of treating all roadside business signs as the same permit case.
- Mark the sign location and identify every road from which it will be visible.
- Describe what the sign advertises and where that activity occurs.
- Obtain current city-limit and ETJ confirmation for that location.
- Ask the city and county for the precise ordinance, statutory exception, or delegation they rely on.
- Ask TxDOT whether state licensing or permitting applies and whether a certified-city arrangement changes the filing route.
- Keep each required approval separate in the schedule; resolve overlapping claims before fabrication.
