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 rulesAndrews County, TX
Zoning & raw-land occupancy
Varies locallyAndrews County has no general zoning power over unincorporated land, per state law limits on Texas counties; the county does regulate subdivision platting. The City of Andrews has its own active zoning and planning process for land inside city limits. source
Dwellings, tiny homes & RVs
Unclear - verifyNo county ordinance on minimum dwelling size or RV/tiny-home occupancy for unincorporated land was found; not confirmed. Ask the county directly.
Building permits & codes
Varies locallyThe City of Andrews has adopted building codes in its Code of Ordinances; no equivalent county-level building code for unincorporated land was confirmed. source
Septic & composting toilets
Generally allowedThe Andrews County Health Department issues OSSF permits as the local agent under the statewide TCEQ program (Texas Health and Safety Code Ch. 366, 30 TAC Ch. 285), requiring a site plan with setbacks and well locations. source
Greywater reuse
Unclear - verifyNo standalone county or TCEQ greywater rule was found; greywater likely falls under the same OSSF permitting framework administered by the county Health Department, but this isn't separately confirmed. source
Rainwater harvesting
Generally allowedNo Andrews County ordinance restricting rainwater harvesting was found, consistent with Texas's general state-level encouragement of it.
Private wells & water rights
Unclear - verifyIt's not confirmed whether Andrews County lies within a Groundwater Conservation District; without one, the state's default rule of capture would apply. Check the Texas Water Development Board's GCD index to confirm. source
Living disconnected from utilities
Generally allowedNo Andrews County ordinance requiring connection to electric, water, or sewer utilities in unincorporated areas was found. Any mandatory-connection rule would more likely come from the City of Andrews for in-town property.
