The local rulesGlasscock County, TX
Zoning & raw-land occupancy
Generally allowedTexas counties, including Glasscock, have no general zoning power over unincorporated land. No county zoning ordinance or department was found. source
Dwellings, tiny homes & RVs
Unclear - verifyNo county ordinance on tiny homes, minimum dwelling size, or RV occupancy was found; this likely inherits the state baseline, which gives counties only narrow authority here.
Building permits & codes
Unclear - verifyThe county's Permits page lists driveway and pipeline crossing permits but no general residential building permit or adopted building code. Confirm with the county courthouse directly. source
Septic & composting toilets
Generally allowedGlasscock County administers OSSF (septic) permits under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285, both state rules carried out at the county level. A permit and approved plan are required before construction. source
Greywater reuse
Unclear - verifyNo standalone county or TCEQ greywater ordinance was found; greywater appears to fall under the same state OSSF rules as septic rather than a separate program.

Generally allowedNo Glasscock County ordinance restricts rainwater harvesting; the state (Texas Water Development Board) generally encourages it statewide.
Private wells & water rights
RestrictedThe Glasscock Groundwater Conservation District, whose boundaries match the county, requires a permit and Board approval before drilling any well, plus compliance with spacing and density rules.
