Gray County, TX Building Permits, Zoning & Septic Rules

Q: Who handles permits in Gray County, and how do you reach them?

Gray County has no building or zoning office to call. For general county business, the County Judge's office at the Gray County Courthouse is the place to start, at 806-669-8008. For septic, Gray County is assigned to TCEQ Region 1 in Amarillo; where no local jurisdiction is authorized, that regional office is the permitting authority. For a well, the Panhandle Groundwater Conservation District covers Gray County; reach it at 806-883-2501 or info@pgcd.us.

Q: Does Gray County have zoning?

Gray County has no zoning ordinance. Texas gives counties zoning power only in a handful of narrowly defined situations, and none of them cover ordinary unincorporated land in Gray County. Because the county has no zoning authority here, there is no county-set minimum dwelling size, setback, lot-coverage limit, or building-height limit, and RVs, tiny homes, manufactured homes, accessory dwellings, and temporary camping are unrestricted by county rule. That's a real answer, not a research gap — it follows directly from the state not giving Gray County that power.

Gray County, Texas has no zoning ordinance and no county building permit for construction in unincorporated areas¹. Gray County is assigned to TCEQ Region 1 in Amarillo, which handles OSSF permitting where no local jurisdiction is authorized². If you're drilling a well, Gray County sits inside the Panhandle Groundwater Conservation District, where every well must be registered and larger wells need a district permit³.

Do you need a building permit in Gray County, Texas?

Gray County's own office list includes no building, planning, or zoning department, and Texas counties generally can't require one for unincorporated construction¹. Gray County also has no zoning ordinance⁴. Texas gives counties limited fire-code and residential-standard authority only to counties over 250,000 people, or those adjacent to one — Gray County, with roughly 21,000 residents, doesn't meet that threshold⁹¹⁰. If you're placing a factory-built industrialized home, Texas still requires the manufacturer's design package to be approved to codes adopted effective July 2024 — that's a manufacturer and state requirement, separate from any county permit¹¹. One thing that is prohibited outright: occupying an uninstalled manufactured home for anything besides viewing it on a retailer's sales lot⁶.

Who handles permits in Gray County, and how do you reach them?

Gray County has no building or zoning office to call⁴. For general county business, the County Judge's office at the Gray County Courthouse is the place to start, at 806-669-8008¹². For septic, Gray County is assigned to TCEQ Region 1 in Amarillo; where no local jurisdiction is authorized, that regional office is the permitting authority².

Does Gray County have zoning?

Gray County has no zoning ordinance⁴. Texas gives counties zoning power only in a handful of narrowly defined situations, and none of them cover ordinary unincorporated land in Gray County¹⁴. Because the county has no zoning authority here, there is no county-set minimum dwelling size, setback, lot-coverage limit, or building-height limit, and RVs, tiny homes, manufactured homes, accessory dwellings, and temporary camping are unrestricted by county rule⁵. That's a real answer, not a research gap — it follows directly from the state not giving Gray County that power.

How do septic permits work in Gray County?

Gray County is assigned to TCEQ Region 1 in Amarillo, and TCEQ says its regional office is the permitting authority where no local jurisdiction is authorized². Submit the application and planning materials to the applicable permitting authority before constructing, altering, extending, or repairing an OSSF²⁷. After an authorization to construct is issued, a TCEQ-licensed designated representative working for the authorized agent inspects the installation against TCEQ criteria or the authorized agent's stricter order; the cited rule does not say every permit-exempt system is inspected¹⁵. A narrow exception may apply to a single-family tract of at least 10 acres when every system part is at least 100 feet from the property line and all other state conditions are met⁷. A composting toilet still requires an approved OSSF for other wastewater⁸.

Can you live in an RV or tiny home on your land in Gray County?

Gray County has no zoning ordinance, and that specifically means there's no county rule restricting RV occupancy, tiny-home occupancy, or manufactured-home placement on unincorporated land⁵. The same absence of zoning means the county sets no minimum dwelling size and no accessory-dwelling restriction either⁵. One statewide rule does apply if you're placing a manufactured home: an uninstalled manufactured home can't be occupied for anything besides viewing it on a retailer's sales lot, so get it installed before you move in⁶. And whatever you live in still needs a permitted, working wastewater system, which for Gray County means TCEQ's Amarillo office¹⁶¹⁷.

Building a home in Gray County: the steps, in order

Call the Gray County Judge's office at 806-669-8008 to confirm there's still no county building-permit or zoning requirement for your project¹².
Confirm the applicable OSSF authority, then submit the application and planning materials; Gray County is assigned to TCEQ Region 1 in Amarillo, which handles permits where no local jurisdiction is authorized².
If your tract is at least 10 acres, single-family, and keeps every part of the OSSF at least 100 feet from the property line, ask whether you qualify for TCEQ's 10-acre septic exemption⁷.
If you're drilling a well, register it with the Panhandle Groundwater Conservation District regardless of size, and expect a drilling and operating permit if it's not on the district's exempt list — call 806-883-2501¹³³.
If you're placing a manufactured home, get it installed before you move in — an uninstalled manufactured home can't be occupied except to view it on a retailer's lot⁶.
If your driveway will connect to a state highway, submit TxDOT Form 1058 and wait for your permit before construction — TxDOT requires 24 hours' notice before you start work in the right of way¹⁸.
If you're placing a factory-built industrialized home instead, confirm with the manufacturer that its design package is approved to the codes Texas adopted effective July 2024¹¹.

What to check before you buy land in Gray County

Soils here are more forgiving than in a lot of Texas: 41% of Gray County's soils are rated without severe limits for a conventional septic drain field, though the rest will still need an engineered or alternative design¹⁹. If you plan to drill a well, know that registration is required no matter how small it is, and Gray County sits in the Panhandle Groundwater Conservation District, which lists 17.5 gallons per minute or less as its registration-only category — bigger wells need a district permit³. Budget for weather, too: Gray County sees severe drought in roughly 31% of years and averages 22.7 inches of precipitation annually²⁰²¹. On cost: Gray County's effective property tax rate runs about 1.4%, with a median annual bill of $1,435, against a typical home value around $104,289 and farmland valued near $1,579 an acre²²²³²⁴²⁵.

Watch-outs

Gray County's own regulations page lists a road-crossing/driveway-access document and a subdivision-regulations document that this guide couldn't open (they're served as Word files) — confirm current road-crossing and subdivision rules with the County Judge's office before you plan access or a lot split¹².
This guide could not confirm whether Gray County requires floodplain-development permits, and no county floodplain office was found — ask the County Judge's office and check FEMA flood maps before you build near a creek or the Canadian River¹².
Confirm the applicable OSSF authority before filing: Gray County is assigned to TCEQ Region 1 in Amarillo, and the regional office handles permitting where no local jurisdiction is authorized².
