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 rulesCollingsworth County, TX
Zoning & raw-land occupancy
Unclear - verifyNo Collingsworth County zoning ordinance or planning department was found; Texas counties generally lack zoning power over unincorporated land unless they opt in, and no opt-in was found here. Confirm with the Commissioners Court. source
Dwellings, tiny homes & RVs
Unclear - verifyNo county rule on tiny homes, minimum dwelling size, or RV occupancy was found. Texas allows counties to opt into residential construction standards since 2009, but no evidence Collingsworth County has done so. source
Building permits & codes
Unclear - verifyNo building department or permit process found on the official county site. Texas doesn't require unincorporated counties to adopt a building code, and none was confirmed for Collingsworth County. source
Septic & composting toilets
Generally allowedSeptic (OSSF) systems are permitted statewide under TCEQ rules requiring a permit and approved plan, though it's unclear whether the county or TCEQ's regional office issues permits locally. Small systems meeting the state's 10-acre exemption criteria may not need a permit. source
Greywater reuse
Unclear - verifyNo separate greywater rule was found for the county or state; greywater appears to be handled within the general OSSF/septic framework rather than as its own program.
Rainwater harvesting
Generally allowedNo county ordinance restricts rainwater harvesting, and Texas broadly permits and encourages it at the state level.
Private wells & water rights
RestrictedCollingsworth County falls under the Mesquite Groundwater Conservation District, which regulates well registration and groundwater use locally rather than leaving it to pure rule of capture. Exact exemption thresholds weren't confirmed, so contact MGCD directly. source
Living disconnected from utilities
Unclear - verifyNo county ordinance requiring utility hookups was found; any such rule would more likely come from a municipality like Wellington, and none was confirmed there either.
