Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.
The local rulesTerry County, TX
Zoning & raw-land occupancy
Varies locallyTexas counties lack general zoning authority, and Terry County has no confirmed general zoning ordinance for unincorporated land. The City of Brownfield has its own zoning and subdivision rules that apply within city limits and its ETJ. source
Dwellings, tiny homes & RVs
Unclear - verifyNo Terry County ordinance on minimum dwelling size, tiny homes, or RV occupancy was found for unincorporated land. Brownfield has its own floor-area rules, but only inside city limits/ETJ. source
Building permits & codes
Unclear - verifyTexas has no single statewide building code, and no official source confirms Terry County has adopted a building code for unincorporated areas. Brownfield administers its own adopted code through a City Building Inspector. source
Septic & composting toilets
Generally allowedSeptic systems (OSSF) are permitted and regulated statewide by TCEQ under Health and Safety Code Chapter 366 and 30 TAC 285. It is not confirmed whether Terry County itself is the TCEQ-authorized local agent or whether the TCEQ regional office handles permits directly, so ask TCEQ or the county. source
Greywater reuse
Unclear - verifyNo standalone greywater program or Terry County ordinance was found; greywater appears to be handled within the same state OSSF framework as septic rather than as its own permit category. source
Rainwater harvesting
Generally allowedNo Terry County restriction on rainwater harvesting was found, and general state policy encourages it for domestic use.
Private wells & water rights
RestrictedTerry County falls within the South Plains Underground Water Conservation District, which regulates well drilling, registration, and spacing under Texas Water Code Chapter 36 rather than pure rule-of-capture. Specific permit details for the district were not directly verified. source
Living disconnected from utilities
Unclear - verifyNo Terry County ordinance requiring connection to electric, water, or sewer utilities was found. Such a requirement, if it exists, would more likely come from a city ordinance in Brownfield or Wellman.
