Read this before you act on anything below. This is my researched starting point for Wilbarger County, TX, not legal advice and not a guarantee. 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 rulesWilbarger County, TX

Zoning & raw-land occupancy
Varies locallyNo countywide zoning ordinance was found for unincorporated Wilbarger County; Texas counties generally lack general zoning power. The City of Vernon maintains its own zoning/use-district code that applies within city limits and ETJ. source
Dwellings, tiny homes & RVs
Unclear - verifyNo Wilbarger County ordinance on minimum dwelling size, tiny homes, or RV occupancy was found; the state baseline (no minimum size, narrow county authority) likely applies outside Vernon, but this isn't independently confirmed. Vernon's code sets tie-down and siting standards for mobile homes within city limits. source
Building permits & codes
Varies locallyThe City of Vernon requires permits for building, electrical, plumbing, and HVAC work through City Hall. No Wilbarger County building code or permit process for unincorporated land was found, and Texas county building-code authority is optional and narrow. source
Septic & composting toilets
Generally allowedWilbarger County isn't listed as having its own TCEQ-delegated OSSF program, so septic permitting in unincorporated areas runs through TCEQ's regional office under statewide rules, including a possible exemption for qualifying 10+ acre sites. source
Greywater reuse
Unclear - verifyNo Wilbarger County-specific greywater ordinance was found; greywater is addressed within TCEQ's statewide OSSF rules rather than as its own program, so check with TCEQ's regional office for specifics. source
Rainwater harvesting
Generally allowedNo Wilbarger County ordinance restricts rainwater harvesting; the state's general allowance for domestic rainwater collection applies by default.
Private wells & water rights
Varies locallyWhether a drilling permit is required depends on whether the property sits inside a Groundwater Conservation District; the Rolling Plains Groundwater Conservation District covers this region, but its coverage of Wilbarger County specifically was not confirmed from available sources, so check with the district or the Texas Water Development Board. source
Living disconnected from utilities
Unclear - verifyNo official Wilbarger County ordinance requiring utility hookups for unincorporated land was found; any mandatory-connection rule would most likely come from the City of Vernon for properties within its limits or ETJ, but that wasn't independently confirmed.
