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 rulesThrockmorton County, TX
Zoning & raw-land occupancy
Unclear - verifyTexas counties generally lack broad zoning power, and I found no evidence Throckmorton County has adopted a zoning ordinance. It's not confirmed whether the towns of Throckmorton or Woodson have their own zoning. source
Dwellings, tiny homes & RVs
Unclear - verifyTexas gave counties optional, limited authority since 2009 to set residential construction standards, but no Throckmorton County ordinance on tiny homes, minimum size, or RV occupancy was found.
Building permits & codes
Unclear - verifyTexas has no statewide building code, and county permitting authority under state law mainly covers commercial or multi-family buildings, not typical single-family homes. No county-specific permit page was found for Throckmorton County. source
Septic & composting toilets
Generally allowedTCEQ, the state agency, requires a permit to construct or operate an on-site sewage facility (septic or holding tank), with a limited exemption for a single dwelling on 10+ acres meeting state siting rules. It's not confirmed whether the county or TCEQ's regional office directly issues these permits locally, so ask both. source
Greywater reuse
Unclear - verifyNo standalone greywater ordinance or program was found; greywater appears to be handled within the state's OSSF/septic rules rather than separately.
Rainwater harvesting
Generally allowedThe state of Texas encourages rainwater harvesting and I found no Throckmorton County restriction on it.
Private wells & water rights
Generally allowedThrockmorton County doesn't appear to be inside any groundwater conservation district, so the state's default rule of capture likely applies; regardless, TCEQ requires wells to be drilled by a licensed driller who files a State Well Report. source
Living disconnected from utilities
Unclear - verifyNo state law or county ordinance requiring utility hookup was found; any such rule would have to come from the towns of Throckmorton or Woodson, which wasn't confirmed.
