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 rulesGray County, TX
Zoning & raw-land occupancy
Unclear - verifyTexas counties generally lack broad zoning power over unincorporated land, and no Gray County ordinance establishing countywide zoning was found. Incorporated towns like Pampa may zone within their own limits, but that's separate from county authority. source
Dwellings, tiny homes & RVs
Unclear - verifyTexas law (since 2009) lets counties adopt limited residential construction standards in unincorporated areas, but no Gray County order doing so was found on the official site. Confirm directly with the county before assuming tiny homes or RVs are unregulated. source
Building permits & codes
Unclear - verifyTexas has no statewide building code, and whether Gray County has adopted one for unincorporated areas isn't confirmed from official sources. Pampa may have its own code within city limits. source
Septic & composting toilets
Generally allowedTCEQ regulates OSSF systems statewide under 30 TAC Chapter 285, under authority of Texas Health and Safety Code Chapter 366. Whether Gray County itself is the local permitting agent or TCEQ's regional office handles it directly isn't confirmed. source
Greywater reuse
Unclear - verifyThere's no standalone TCEQ greywater program; it's generally covered within the OSSF framework. No Gray County-specific greywater rule was found. source
Rainwater harvesting
Generally allowedTexas state policy encourages rainwater harvesting, and no Gray County restriction on it was found.
Private wells & water rights
RestrictedGray County is part of the Panhandle Groundwater Conservation District (PGCD), which regulates well registration, spacing, and production under Texas Water Code Chapter 36. Specific PGCD requirements for Gray County weren't independently verified. source
Living disconnected from utilities
Unclear - verifyNo Texas law requires utility hookup, and no Gray County ordinance on utility disconnection was found, unlike some other Texas counties that do have such rules. source
