Rural land rules in the 254 Texas counties

Water wells, septic, electricity, mobile homes and agricultural valuation. Pick a county to see what the official source says and when we checked it.

This is not legal advice. Rules change, so confirm with the office that issues the permit before you buy or build.

How we build it

We use AI to find and read the official documents of each county, groundwater district and state agency. We only publish what an official source says, we link to it, and we treat every county the same way.

Coverage varies by county and topic. A gray status means we have not found a published rule yet, and we do not guess. Last update: November 11, 2026.

What each status means

Published rule
An official source states the rule, and we link to it.
In review

No local rule
We have not identified an additional local requirement for this topic here, according to the official source. State rules and other regulations may still apply.

Water well. Household well rules are set by the groundwater conservation district, not by the county. District boundaries come from the TCEQ map.

Septic system. The septic permit is issued by the TCEQ authorized agent, usually the county itself. The list comes from the TCEQ 2025 report of authorized agents.

Electricity. Who holds certificated territory to provide electricity, from the PUC of Texas layers. The PUC labels these layers unofficial: the official boundaries are its paper maps. Where the provider is Oncor, CenterPoint, AEP Texas or TNMP, that company owns the lines and you buy power from a retail provider.

Mobile home and RV. Rules for placing a mobile home, manufactured home or RV on your land.

Agricultural valuation. State law asks that the land was used for agriculture 5 of the last 7 years, and allows beekeeping on 5 to 20 acres (Texas Tax Code 23.51). Each appraisal district sets its own guidelines.

Exempt wells need no permit but must be preregistered before drilling and registered, and they remain subject to spacing rules. Domestic or livestock wells on tracts of 10 acres or less are not exempt and need a permit.

It does not require a permit for a domestic well, or a livestock well on a tract over 10 acres, that cannot produce more than 25,000 gallons a day, but the well must be registered (Rules 8.2 and 7.0). Domestic and livestock wells must be 50 feet from property lines and 100 feet from septic absorption fields (Rule 9.0).

Nueces County

Water well: Published rule

The district defines an exempt well as one drilled or equipped to produce no more than 50,000 gallons a day, or to water livestock and poultry for a farming operation. Before drilling an exempt well you must apply for a drilling registration. A new well may not be drilled within 50 feet of a neighbor's property line. [Covers 23% of the county.] A well used solely for domestic or livestock use needs no operating permit, unless it will supply a subdivision that requires plat approval. Even so, every well must be registered with the district, and a new well cannot be drilled before it is registered. The minimum distance from a new well to a property line is 100 feet for 20 gallons per minute or less, and 5 feet per gallon per minute between 20 and 250. [Covers 4% of the county.] The other 73% of the county has no district.
