Moore County, TX Building Permits, Zoning & Septic Rules

Q: Building a home in Moore County: the steps, in order

Confirm your parcel is in unincorporated Moore County land, not inside Dumas, Sunray, Cactus, or Fritch, since city rules would replace these county rules. Get a site evaluation for septic before you commit to a house site: contact the TCEQ Region 1 office in Amarillo, the OSSF permitting authority for Moore County, and apply for your septic permit before construction starts. If you will cut a new driveway onto a county road, check with the Moore County Road & Bridge Department first; if your access is instead onto a state highway, you need a TxDOT permit and advance notice before construction. Build to whatever standard you choose beyond septic: no county building permit or inspection applies in unincorporated Moore County. For an ag exemption question, a subdivision plat, or a question about who currently handles floodplain matters, call the Moore County Judge's office to be pointed to the right authority.

Unincorporated Moore County, Texas does not require a building permit for a home, and the county has no zoning ordinance¹². There is no county septic office either: Moore County has no local on-site sewage facility (OSSF) program, so the Texas Commission on Environmental Quality's regional office in Amarillo permits septic systems for the county³⁴. The tradeoff: with no zoning, nothing on paper restricts an RV, tiny home, or manufactured home on your land, but you still need a state septic permit before you build⁵.

Do you need a building permit in Moore County, Texas?

Unincorporated Moore County does not require a building permit to put up a home, barn, or shed¹. Texas gives counties no general power to require building permits outside city limits, and Moore County lists no building department or code-enforcement office on its official site, which is consistent with that state limit¹⁸. That changes if you build inside Dumas, Sunray, Cactus, or Fritch, or in one of their extraterritorial jurisdictions, where the city's own codes and any city permit requirements apply instead. This guide covers unincorporated county land, not land inside a city.

Who do you call about permits and building questions in Moore County?

There is no Moore County building department, planning office, or floodplain administrator to call, because the county has not created those offices¹². For a septic (OSSF) permit, the authority is not the county at all: contact the TCEQ Region 1 office in Amarillo, which TCEQ's own county lookup lists as Moore County's authorized OSSF permitting agent⁴. For anything involving a county road, including a new driveway cut onto one, the Moore County Road & Bridge Department is the office to call⁹. For a general question that doesn't fit either of those, or to ask who currently handles floodplain or subdivision matters, start with the Moore County Judge's office, which sits over the Commissioners Court¹⁰.

Does Moore County have zoning?

No: Moore County has no zoning ordinance, and its official site lists no planning or zoning department². Texas law gives counties zoning power only in a handful of narrow, named situations, such as parts of Padre Island in Cameron and Willacy Counties, and Moore County does not fall under any of them, so the county has no general zoning authority to exercise even if it wanted to¹¹. In practice this means no countywide minimum home size, no minimum lot size, no setbacks, no lot-coverage limit, and no building-height limit apply to unincorporated Moore County land⁵. It also means the county does not restrict accessory dwellings, RVs, tiny homes, or manufactured homes on a parcel by zoning, because there is no zoning to do the restricting⁵. None of this applies inside Dumas, Sunray, Cactus, or Fritch: a city's own ordinances govern land inside its limits and, in many Texas cities, inside its extraterritorial jurisdiction too.

How do septic permits work in Moore County?

Texas requires a permit and an approved plan before you construct, alter, extend, or repair a septic system (an OSSF), and that rule applies in Moore County the same as anywhere else in the state⁶. Because Moore County has no local health department or OSSF program, the TCEQ regional office in Amarillo is the permitting authority, reviewing plans, issuing the permit, and inspecting the installation³⁴¹². Only 32.7% of Moore County's soils are rated free of severe limitations for a conventional septic drain field, so plan on a site evaluation early and budget for an engineered or alternative system if your site is among the majority with limiting soils¹³. A narrow exemption exists for a single-family home on a tract of 10 acres or more: it applies only if a TCEQ-licensed site evaluator or engineer signs off, every part of the system stays at least 100 feet from the property line, effluent stays on your property, the system causes no nuisance or groundwater pollution, and the home is the only dwelling on the tract⁶. Skip a required permit and you risk a system that a lender or future buyer can't verify, on top of any state enforcement.

Can you live in an RV or tiny home on your land in Moore County?

Moore County's lack of zoning means the county does not restrict RV or tiny-home occupancy on unincorporated land by ordinance⁵. That is a real answer, not a gap: it follows from Texas law limiting county zoning power and from Moore County never having adopted a zoning ordinance¹¹. It is not the same as a guarantee that nothing else applies. Any RV, tiny home, or manufactured home still needs a compliant septic system before wastewater can legally be disposed of, which means the TCEQ permit above applies to a permanent house and to a trailer parked long-term alike³. If your land sits inside or near Dumas, Sunray, Cactus, or Fritch, confirm you are outside city limits and any extraterritorial jurisdiction before assuming county-only rules apply, since a city's own RV and occupancy rules would take over there.

Building a home in Moore County: the steps, in order

Confirm your parcel is in unincorporated Moore County land², not inside Dumas, Sunray, Cactus, or Fritch, since city rules would replace these county rules.
Get a site evaluation for septic before you commit to a house site: contact the TCEQ Region 1 office in Amarillo, the OSSF permitting authority for Moore County, and apply for your septic permit before construction starts⁴⁶.
If you will cut a new driveway onto a county road, check with the Moore County Road & Bridge Department first⁹; if your access is instead onto a state highway, you need a TxDOT permit and advance notice before construction⁷.
Build to whatever standard you choose beyond septic: no county building permit or inspection applies in unincorporated Moore County¹.
For an ag exemption question, a subdivision plat, or a question about who currently handles floodplain matters, call the Moore County Judge's office to be pointed to the right authority¹⁰.

What to check before you buy land in Moore County

Water and soils come first: 97.3% of Moore County land sits at 15% slope or less, which is easy to build on, but only 32.7% of soils are rated free of severe limits for a conventional septic drain field, so get a site evaluation before you assume a standard system will work¹⁴¹³. The county is dry and drought-prone: average annual precipitation is 18.2 inches, and the area has spent 38.1% of recent years in severe drought, which matters for both a private well and for landscaping or livestock plans¹⁵¹⁶. Ask specifically which groundwater conservation district, if any, covers your parcel before drilling a well; Texas gives no state agency direct authority over groundwater production, and Moore County's own site does not identify a district for a given tract, so this needs a direct call rather than an assumption. Moore County is rural and sparsely populated, at 23.6 people per square mile, and sits about 45 miles from the nearest metro area, so factor in drive time for supplies, services, and emergency response¹⁷¹⁸. Farmland in the county has recently been valued around $1,836 an acre, and the typical home value is about $192,223, useful benchmarks when you're pricing a parcel¹⁹²⁰. Property taxes run an effective rate near 1.5%, with a median bill around $2,066 a year, and a typical home insurance premium runs about $2,148 a year in the area²¹²²²³.

Watch-outs

Moore County's official site does not state whether it has adopted a fire code or the optional residential building-code standards Texas law allows some counties to adopt; if you need certainty for a loan or insurance, ask the Moore County Judge's office directly rather than assuming no county rule applies at all¹⁰⁸.
No official Moore County page identifies who administers floodplain rules or reviews subdivision plats; call the Moore County Judge's office to find the current contact before you assume there is none¹⁰.

- The fire code does not apply to an industrial facility having a fire brigade that conforms to Occupational Health and Safety Administration requirements.

- The fire code must conform to the International Fire Code or Uniform Fire Code as those codes existed on May 1, 2005, or establish protective measures exceeding those standards; later editions may be adopted.
- Residential standards under Section 233.152 apply only if the county adopts a resolution or order and the county is within 50 miles of an international border or has a population over 100.
