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 rulesNolan County, TX
Zoning & raw-land occupancy
Generally allowedTexas counties generally lack zoning authority outside city limits, and Nolan County is not among the specially authorized counties under Local Government Code Chapter 231. Raw-land occupancy is unregulated by the county; only Sweetwater or Roscoe city limits could impose zoning. source
Dwellings, tiny homes & RVs
Unclear - verifyNo Nolan County ordinance on tiny homes or RV occupancy was found. State law limits county authority over dwelling type outside city limits; confirm directly with the county.
Building permits & codes
Unclear - verifyTexas Local Government Code Chapter 233 lets counties require permits outside city limits only in narrow cases (commercial, multi-family, manufactured homes, substantial improvements); whether Nolan County has adopted any voluntary permit program is not confirmed. source
Septic & composting toilets
Generally allowedOSSFs are permitted statewide under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285. Nolan County does not appear to be a TCEQ Authorized Agent county, so permitting likely runs through the regional TCEQ office, but this is not confirmed on an official Nolan County page. source
Greywater reuse
Unclear - verifyGreywater is handled within the same state OSSF framework (30 TAC 285); no standalone Nolan County greywater rule was found. source
Rainwater harvesting
Generally allowedNo Nolan County ordinance restricting rainwater harvesting was found; state policy generally encourages it, though this wasn't verified against a state-specific page.
Private wells & water rights
Varies locallyNolan County has its own groundwater district, the Wes-Tex Groundwater Conservation District, created by the Texas Legislature to manage local groundwater; well drillers should check its registration, spacing, and production rules rather than relying only on the statewide rule of capture. source
Living disconnected from utilities
Unclear - verifyNo state or Nolan County rule requiring utility hookup in unincorporated areas was found; any such requirement would come from Sweetwater or Roscoe municipal code instead.
