Building permits, zoning and land rules in Terry County, Texas

Unincorporated Terry County does not generally require prior county approval through a residential building permit^1,2. The current county inspection program could not be confirmed; Chapter 233 inspections apply only if an eligible county adopts the program². A separate fire-code building permit can apply to commercial buildings, public buildings and multifamily buildings with four or more units only in a qualifying county that adopts a fire code, and we could not confirm a Terry County adoption². Industrialized housing and buildings are a separate category subject to mandatory state codes¹¹. Manufactured homes also remain subject to statewide installation and occupancy standards⁸. Ask the Terry County Judge's Office whether floodplain approval or a residential inspection notice applies before construction^12,13.

Terry County does not publish a separate building or planning office, so begin building-permit, residential-inspection and floodplain questions with the Terry County Judge's Office at the courthouse on Main Street in Brownfield¹². We could not confirm the current floodplain administrator, floodplain application, building-permit fees or county-road driveway process. Inside Brownfield, the city's zoning rules apply, but septic permits remain with South Plains Public Health District under the state-and-local OSSF framework^4,5,7. A driveway connecting to a state highway follows TxDOT's process: Form 1058 is required for a new or modified driveway, and right-of-way construction must wait for an executed driveway permit and notice to TxDOT¹⁰.

Unincorporated Terry County has no general county zoning authority, so county zoning does not set minimum dwelling size, minimum lot size, setbacks, lot coverage, building height or occupancy rules for RVs, tiny homes and accessory dwellings³. Brownfield is different: the city divides its land into zoning districts with overlay zones, and the City of Brownfield Building Inspector or a designee administers and enforces that zoning, while septic permits for Terry County addresses remain with South Plains Public Health District^4,5. Private deed restrictions, floodplain controls, septic siting and statewide housing standards can still limit a project^7,8,13. Land divisions outside municipal limits generally require a plat that the Terry County Commissioners Court approves by order, with exceptions such as divisions where all lots exceed 10 acres¹⁴. A division kept primarily in qualifying agricultural, farm, ranch, wildlife-management or timber-production use can be exempt when no covered public-use area is laid out, but platting requirements return if that use ends¹⁵.

South Plains Public Health District handles Terry County septic permits and inspections⁵. The septic application requires site and soil information, and construction must wait for district authorization⁶. The district's published OSSF inspection fee is $400, a visual inspection of a permitted or non-permitted system is $200, and a $100 expedited fee applies to applications without 7 days' notice¹⁶. Texas generally requires a septic permit and approved plan to construct, alter, repair, extend or operate an OSSF⁷. A narrow exemption may apply to one single-family dwelling on at least 10 acres when a licensed evaluator or engineer evaluates the site, every system component stays at least 100 feet from the property line, effluent remains on the tract and every other condition is met⁷. The installation must be inspected before it is covered^5,17. About 87.5% of Terry County soils avoid a severe conventional-drain-field limitation, but every homesite still needs its own evaluation¹⁸.

Unincorporated Terry County has no county zoning rule restricting RV occupancy, tiny-home occupancy, temporary camping, accessory dwellings or minimum dwelling size³. That answer does not override private deed restrictions, floodplain controls or Brownfield zoning inside the city^4,13. An occupied RV or tiny home still needs lawful sanitation: South Plains Public Health District requires authorization before septic construction and requires the system to follow the approved site materials and map⁶. A manufactured home must follow statewide installation and occupancy standards, and Terry County is in manufactured-housing Wind Zone I⁸. An owner may install a septic system for an owner-occupied single-family home only when every district and state condition is met⁵. Ask the district about the sanitation design before placing or occupying a unit¹⁹.

1. Ask the Terry County Judge's Office whether the parcel needs floodplain approval or falls under an adopted residential inspection program^2,12,13.

1. Confirm that the parcel is outside Brownfield before relying on the unincorporated-county zoning answer⁴.

1. Contact South Plains Public Health District for the site-and-soil evaluation and septic permit before construction begins⁶.

1. Contact the South Plains Underground Water Conservation District before drilling a non-exempt well; the district issues well-drilling permits and inspects completed sites⁹.

1. Obtain a TxDOT driveway permit before building or changing access onto a state highway¹⁰.

1. Apply the correct statewide codes and installation standards to industrialized or manufactured housing^8,11.

Start with legal access, the Brownfield city boundary, floodplain status, deed restrictions and whether a proposed division needs a plat^4,13,14. Water deserves early planning: non-exempt district wells need a drilling permit, while Terry County averages about 17.3 inches of precipitation and experiences severe drought in about 40.2% of years^9,18. The land is overwhelmingly gentle, with 99.9% at a slope of 15% or less, and only 0.1% is wooded¹⁸. Conventional septic conditions are comparatively favorable across much of the county, but the district still requires parcel-level soil and site information^6,18. The typical effective property-tax rate is about 1.5%, with a median annual bill near $1,645¹⁸.
