Buying Land in Texas

Zoning: most rural Texas counties have none

This is the single biggest difference between Texas and most other states: Texas counties generally have no general zoning authority at all, in either the unincorporated county or a city's extraterritorial jurisdiction (ETJ). Zoning power in Texas belongs mainly to incorporated cities. Chapter 231 of the Texas Local Government Code grants a handful of narrow, named exceptions -- zoning authority for specific areas like Padre Island (Cameron and Willacy Counties), land near certain military installations, and land around a short list of named lakes and recreation areas -- but outside those listed exceptions, a Texas county commissioners court cannot adopt a general zoning ordinance.

That does not mean unincorporated Texas land is unregulated. Counties do have authority to regulate subdivision platting, floodplain development, and (in many counties) some site development and manufactured-home placement standards, plus whatever a municipality's ETJ subdivision rules impose if the parcel is close enough to a city. It just means "not zoned" is a genuinely common and legally accurate answer in rural Texas, in a way it usually isn't elsewhere -- confirm the specific county's platting and subdivision rules rather than assuming "no zoning" means "no rules."

Septic (OSSF) permitting: TCEQ sets the rules, but who issues your permit depends on the county

The Texas Commission on Environmental Quality (TCEQ) writes the statewide technical rules for on-site sewage facilities (OSSFs, i.e., septic systems) under 30 TAC Chapter 285 -- setback distances, system design standards, and installer/inspector licensing are all set at the state level. But TCEQ does not issue most individual permits itself.

A meaningful share of Texas counties (and some city-county health districts) have signed on as TCEQ "authorized agents," which means the county health department or environmental services office actually reviews site evaluations, issues the OSSF permit, and performs inspections under a delegation agreement with TCEQ. In counties that have not become an authorized agent, permitting for OSSFs is instead handled directly by one of TCEQ's regional offices rather than the county. Either way, you still need a passed site/soil evaluation and an issued permit before installation -- see our national guide to septic systems and perc tests for that process. What changes by county is simply who at the desk is doing the reviewing.

• Before assuming a process or timeline, ask the target county directly whether it is a TCEQ authorized agent for OSSF permitting, or whether that county's permits run through a TCEQ regional office instead.
• Authorized-agent status, fee schedules, and local supplemental requirements can and do vary by county even though the underlying technical rules (30 TAC 285) are statewide.

Water rights: the rule of capture, not riparian rights

Texas groundwater law is a real outlier compared to the riparian-rights doctrine used in most of the eastern and southern US. Under Texas's rule of capture (a doctrine dating to a 1904 Texas Supreme Court decision), a landowner may generally pump as much groundwater as they can put to beneficial use from beneath their own land, without liability to a neighbor whose well happens to go dry as a result -- subject to narrow exceptions for malicious or wasteful pumping. There is no general state permitting requirement for groundwater production; the Texas Water Development Board and TCEQ both note that no single state agency directly regulates how much groundwater a landowner may pump.

In practice, though, this is heavily localized. Roughly a hundred Groundwater Conservation Districts (GCDs), authorized under Chapter 36 of the Texas Water Code, cover large parts of the state and are the state's preferred mechanism for actually managing groundwater -- they can require well permits, set spacing rules, cap production, and require metering, and their rules vary district by district. Whether your parcel sits inside a GCD, and what that district's specific well-permitting and spacing rules require, is one of the most consequential things to check before you count on a well for a Texas property.

Manufactured and modular homes

Manufactured housing in Texas is regulated at the state level by the Texas Department of Housing and Community Affairs (TDHCA) Manufactured Housing Division, under the Texas Manufactured Housing Standards Act (Texas Occupations Code Chapter 1201) and TDHCA's administrative rules (10 TAC Chapter 80). Installation must be performed by a state-licensed installer, following the manufacturer's instructions and TDHCA's foundation, anchoring, and blocking standards -- this licensing and installation-standard layer applies statewide regardless of what a given county otherwise regulates.

What is not uniform statewide is whether a manufactured home is even allowed on a given parcel and what it has to look like once it's there -- that's a mix of county subdivision rules (where they exist), any deed restrictions on the specific tract, and, near a city, that city's ETJ rules. TDHCA governs how the home is installed; it does not decide whether your parcel is allowed to have one.

Right to farm and agritourism liability

Texas has a Right to Farm statute (Texas Agriculture Code Chapter 251) that generally prevents a nuisance lawsuit against an agricultural operation that has been in continuous, substantially unchanged operation for at least a year -- meaningful protection if you're buying land to farm or ranch near land that's already developed, or the reverse. A 2023 amendment raised the evidentiary bar (clear and convincing evidence) for a plaintiff trying to overcome that protection.

Separately, if agritourism (u-pick, hunting leases, farm tours, wedding-barn events, and similar) is part of the plan, Texas's Agritourism Act (Texas Civil Practice & Remedies Code Chapter 75A) offers limited liability protection to an "agritourism entity" for injuries from the inherent risks of the activity -- but only if the statute's specific posted-warning-sign language or written-agreement language is actually in place. It does not cover gross negligence, intentional acts, or an injured employee, and the exact signage wording matters -- this is worth a short conversation with a Texas attorney before opening land to paying visitors, not something to assume you're covered on.

What this page can't tell you

Everything above is genuinely statewide. What isn't: whether your specific county has adopted any subdivision or manufactured-home rules, whether it's a TCEQ OSSF authorized agent or routes through a regional office, whether it sits inside a Groundwater Conservation District and what that district's well rules require, and what the county appraisal district requires for an agricultural (ag/wildlife) valuation. Those are exactly the questions a county-level page and a call to the county itself are for.
