Texas zoning: how it works and what you can build
Texas is defined by strong home-rule city authority, essentially no county zoning power over unincorporated land, and Houston's famous absence of a formal zoning code — making feasibility hinge as much on deed restrictions, extraterritorial jurisdiction, and platting rules as on conventional Euclidean zoning maps.
How zoning works in Texas
Municipal zoning authority in Texas flows from Chapter 211 of the Texas Local Government Code. Home-rule cities, generally those with a population over 5,000 that have adopted a home-rule charter, have broad zoning powers and can amend their codes relatively freely; general-law cities have narrower, more statutorily constrained authority. Houston is the notable exception: it is the largest city in the United States without a formal zoning ordinance, and land use there is instead shaped by private deed restrictions recorded against subdivisions, combined with citywide development regulations covering minimum lot size, parking, setbacks, and historic preservation.
Texas counties, by contrast, have no general zoning authority over unincorporated land — a defining and often surprising feature of the state's land-use system for developers coming from elsewhere. Counties can regulate subdivision platting, roads, and drainage under Chapter 232 of the Local Government Code, and a few narrow statutory exceptions exist for specific situations, but they cannot impose Euclidean use-district zoning the way a city can. This leaves large stretches of unincorporated exurban Texas effectively unzoned, and it makes a city's extraterritorial jurisdiction (ETJ), the ring of unincorporated land around a city where it can review and require compliance with subdivision plats, one of the main levers shaping growth at the urban edge.
The 2023 legislative session was active on land-use-adjacent issues: SB 2038 created a process for property owners in a city's ETJ to petition for release from that jurisdiction, and HB 2127 broadly preempted local ordinances that exceed state law across several regulated fields. Separately, Austin has pursued the most aggressive missing-middle reform of any major Texas city, amending its Land Development Code through its HOME initiative to allow more units by right on land historically zoned for single-family use.
Who holds the zoning power
Land-use authority in Texas is delegated by statute, not assumed — these are the acts a zoning ordinance in Texas has to trace back to.
- Municipal Zoning Authority Texas Local Government Code, Chapter 211
- Grants Texas municipalities zoning power; home-rule cities (generally population 5,000+) have broader authority than general-law cities.
- County Regulation of Subdivisions Texas Local Government Code, Chapter 232
- Texas counties generally lack zoning authority over unincorporated land, but may regulate subdivision plats, roads, and drainage.
Major cities and their codes
The enabling act sets the ceiling; the municipal code is what a project is actually reviewed against. The 7 largest Texas jurisdictions and the codes they administer:
| City | Zoning code |
|---|---|
| Houston | No zoning code The largest U.S. city without formal zoning; land use is governed by private deed restrictions and the city's subdivision and development ordinances, so feasibility review centers on deed restrictions and platting. |
| Austin | Austin Land Development Code Adopted the citywide HOME initiative (2023-2024), allowing additional units by right on most single-family-zoned lots and reducing minimum lot size. |
| San Antonio | San Antonio Unified Development Code (UDC) Consolidates zoning and subdivision regulations citywide, with military-compatibility overlay zoning around Joint Base San Antonio. |
| Dallas | Dallas Development Code, Chapter 51A Base zoning ordinance has been amended by hundreds of individual planned-development (PD) district overlays since its adoption. |
| Fort Worth | Fort Worth Zoning Ordinance Rapid greenfield growth on the city's west and north sides alongside a form-based code push in near-downtown neighborhoods. |
| El Paso | El Paso Zoning Ordinance Binational border geography constrains developable land to a narrow corridor along the Rio Grande. |
| Arlington | City of Arlington Zoning Ordinance Land-locked between Dallas and Fort Worth, with entertainment-district overlay zoning around its stadium and convention venues. |
Recent reforms
State-level changes override or preempt what a local ordinance says — these are the Texas reforms that move the numbers on a real site.
- 2023 SB 2038 Allows property owners in a city's extraterritorial jurisdiction (ETJ) to petition for release from that jurisdiction, reducing city control over unincorporated fringe land.
- 2023 HB 2127 (Texas Regulatory Consistency Act) Broadly preempts local ordinances that exceed state law across several regulated fields, narrowing municipal regulatory authority statewide.
Parcel & GIS data
Texas has no single statewide parcel GIS layer; the Texas Natural Resources Information System (TNRIS) and its StratMap program coordinate imagery and some data aggregation, but authoritative parcel records are maintained separately by each county appraisal district.
Real parcel geometry is already loaded for Arlington and Austin — see the zoning-by-city section above for a live district-and-parcel lookup there. That is not the same as a cited feasibility report: Chicago is still the only jurisdiction with bulk standards, § citations and a generated massing scheme.
Zoning by city
The statute sets who may zone; the city's own code sets what you can build. One guide per Texas city below, explaining the district codes that appear on its zoning map — 76 district codes across Texas so far.
Texas zoning — common questions
- Does Houston have zoning?
- No. Houston is the largest U.S. city without a formal zoning ordinance. Land use is instead shaped by private deed restrictions recorded against individual subdivisions, along with citywide regulations on minimum lot size, parking, setbacks, and historic preservation. Developers need to research deed restrictions separately from any city land-use review.
- Can Texas counties zone unincorporated land?
- Generally no. Texas counties lack general zoning authority under state law, which is a significant difference from most other states. Counties can regulate subdivision platting, roads, and drainage under Chapter 232 of the Local Government Code, but cannot impose Euclidean use-district zoning outside a handful of narrow statutory exceptions.
- What is Texas ETJ and why does it matter for development?
- Extraterritorial jurisdiction (ETJ) is the ring of unincorporated land around a Texas city where that city can review and enforce compliance with subdivision plats, even though it has no full zoning authority there. A 2023 law, SB 2038, created a process for property owners inside a city's ETJ to petition to be released from it, which can change which subdivision rules apply to a given tract.
- Can I build a triplex on a single-family lot in Austin?
- In many cases, yes. Under Austin's HOME initiative amendments to the Land Development Code, adopted in 2023 and 2024, most single-family-zoned lots citywide may now have up to three residential units by right, subject to site development standards like impervious cover and compatibility rules. Confirm current standards for the specific lot, since Austin has continued to refine these rules.
