Building permits, zoning and land rules in Glasscock County, Texas

Unincorporated Glasscock County, Texas does not require a county building permit to build a home¹. The county's own permits page lists only three permits: for septic systems, pipeline crossings, and driveways, with no residential building or occupancy permit among them¹. That's consistent with Texas law, which does not give most counties general building-permit authority over unincorporated areas⁷. Septic, though, is not optional if you're not on a public sewer line: Glasscock County issues its own on-site sewage facility (OSSF) permit, and that's the one permit almost every rural buyer here will need³.

Glasscock County has no separate building department¹. Septic, pipeline-crossing, and driveway permits are all handled out of the Glasscock County Courthouse, 117 E. Currie Street in Garden City, at (432) 354-2639, Monday through Friday, 8:30am to 4:00pm¹. For anything not covered by those three permits, including the county's subdivision and manufactured-home rental-community regulations, the Commissioners Court is the governing body to contact, at the same courthouse address and phone number^8,9. Water wells go to a different office entirely: the Glasscock Groundwater Conservation District at 132 N. Main in Garden City, (432) 354-2430⁴.

Glasscock County has no general zoning ordinance: Texas law gives counties zoning power only in a handful of specific, named situations, and none of those provisions reaches Glasscock County². Because the county has no zoning authority here, no county rule sets minimum lot size, setbacks, building height, or minimum dwelling size, and living in an RV, tiny home, or manufactured home on your own land is unrestricted by any county zoning rule². That doesn't mean unincorporated Glasscock County has zero land-use rules: the county adopted subdivision and manufactured-home rental-community regulations effective in 2013, available in full from the Glasscock County Clerk's office, and those may still apply if your property sits inside a platted subdivision; state exemptions, including one for agricultural use, also apply^8,9.

Glasscock County itself issues the on-site sewage facility (OSSF) permit for septic systems, not a regional health district³. The process starts with two soil borings at opposite ends of the proposed drainfield, a site plan, and planning materials submitted to the county for review; once approved, the county issues an Authorization to Construct valid for 1 year, and installation still needs a final inspection with at least 5 working days' notice, followed by a Notice of Approval typically issued about 5 working days after a passing inspection⁵. A system that fails inspection cannot be used until it passes¹⁰. A new residential installation permit costs $160, payable to Glasscock County, plus a re-inspection fee equal to half the permit amount for each additional inspection⁵. Soils are a real constraint here: only about 17.8% of the county's land lacks severe limitations for a conventional septic drainfield, so plan on an early site evaluation and budget for an engineered or aerobic system if yours tests poorly⁶. An owner may install the system for the home the owner lives in only if the county's local requirements allow it, and no part of the property may be developed for sale or lease¹¹. Texas also lets a single-family home on 10 acres or more skip the OSSF permit if it meets the state's full list of conditions, including keeping every part of the system at least 100 feet from the property line¹¹.

Yes, as far as county zoning is concerned: Glasscock County has no zoning ordinance, so no county rule limits RV, tiny-home, or manufactured-home occupancy on your own land². That's a zoning answer, not a septic or utility answer — if anyone is living on the property, Glasscock County's OSSF rules still require a permitted septic system (or a qualifying exemption) for the wastewater those occupants generate^3,11. If your land is inside a platted subdivision, check the county's 2013 subdivision and manufactured-home rental-community regulations before assuming there are no restrictions, since those are handled separately from zoning⁹.

1. Confirm your parcel isn't inside a platted subdivision with its own manufactured-home or use restrictions by checking with the Glasscock County Commissioners Court / county clerk at the courthouse^8,9.
2. If you'll drill a water well, apply for a permit and put down a deposit with the Glasscock Groundwater Conservation District before you drill⁴.
3. Have a site evaluation done and apply for a Glasscock County OSSF (septic) permit; budget $160 for a new residential installation, and expect two soil borings as part of the review⁵.
4. Wait for the county's Authorization to Construct before starting any septic installation, then schedule the final inspection at least 5 working days ahead⁵.
5. If your driveway will connect to a state highway, apply to TxDOT for a driveway permit on Form 1058 before building it; if it connects to a county road instead, get the county's residential or commercial driveway permit from the courthouse^1,12.
6. No county building or zoning permit is required for the home itself in unincorporated Glasscock County, but keep your septic and well permits on file — they're what a lender, insurer, or future buyer will ask to see¹.

Water is the first thing to check: Glasscock County averages only 17.3 inches of precipitation a year and sees severe drought in about 28.4% of years, and any well you drill needs a permit and board approval from the Glasscock Groundwater Conservation District^4,6. Soils matter just as much for septic: only about 17.8% of the county's land is free of severe limitations for a conventional drainfield, so get a site evaluation before you count on a standard system⁶. Whether the county has its own floodplain-development rule is not confirmed in official sources reviewed for this guide, so ask the Commissioners Court directly before buying in a low-lying area⁸. Access matters too: a driveway connecting to a state highway needs a separate TxDOT permit from any county driveway permit¹². Property taxes here run about 0.5% of value, with a median bill around $1,154 a year⁶.
