Do you need a building permit in Concho County, Texas?
Unincorporated Concho County does not require a county building permit for a home1. No separate county building-inspection requirement or certificate-of-occupancy rule could be confirmed, so ask the County Judge / Commissioners Court about current county practice before construction8. Texas gives counties only limited building authority: qualifying counties may adopt fire-code permits for commercial buildings, public buildings and larger multifamily projects, while a separate residential framework requires county adoption9.
The county has no documented owner-builder exemption mechanism7. For an ordinary unincorporated home, that is not the same as needing an exemption from a county building permit. Parcels inside Paint Rock or another incorporated city need a separate city-level check because municipal requirements are outside the county answer. Factory-built industrialized housing and modular components can also fall under a partial statewide code program even where a conventional site-built home has no county permit10.
Who handles building permits and land questions in Concho County?
Concho County does not list a separate building, planning or zoning department, which is consistent with the finding that a home-building permit is not required on unincorporated land1. For a parcel-specific question, contact the Concho County Judge / Commissioners Court at 152 N. Roberts in Paint Rock or call (325) 732-43228.
Septic work has its own contact: the Concho County OSSF Program handles county inspections outside incorporated cities at 325-456-460711. Water-well questions require another jurisdiction check. In the part of Concho County within Hickory Underground Water Conservation District No. 1, contact the district in Brady before drilling512. A new or modified driveway connecting to a Texas state highway goes through the local TxDOT district using Form 1058, and right-of-way construction cannot begin until the permit is executed13.
Does Concho County have zoning?
Unincorporated Concho County has no county zoning ordinance2. Texas county zoning authority is limited to specifically authorized places and subjects rather than being a general statewide county power14. As a result, Concho County sets no zoning-based minimum dwelling size, minimum lot size, setback, lot-coverage limit or building-height limit on unincorporated land6.
The same conclusion applies to county zoning restrictions on accessory dwellings, manufactured homes, tiny homes, RV occupancy and temporary camping on unincorporated land6. That answer concerns county zoning only. It does not remove septic rules, groundwater-district rules, state-highway access permits, private deed restrictions or rules inside an incorporated city. The county website does not expressly publish a building-code adoption statement, and no county floodplain-development rule could be confirmed; ask the County Judge / Commissioners Court about both before buying or placing improvements8.
How do septic permits work in Concho County?
The Concho County OSSF Program handles septic inspections in unincorporated Concho County and expressly excludes incorporated cities3. Texas generally requires a permit to construct, install, alter, extend or repair a septic system, and an authorized agent inspects construction after authorization415. Contact the county program at 325-456-4607 before choosing or installing a system11.
The Texas exemption for a single-family home on a tract of at least 10 acres is narrow: it also requires a licensed site evaluation, at least 100 feet between every system part and the property line, on-property effluent disposal, no nuisance or groundwater pollution, and no other dwelling on the tract4. Concho County's soils add practical risk because only about 9% are rated without severe limitations for a conventional septic drain field16. Budget for a site evaluation before treating a conventional system as feasible.
Can you live in an RV or tiny home on your land in Concho County?
Unincorporated Concho County has no county zoning restriction on RV occupancy, tiny-home occupancy, manufactured-home occupancy or temporary camping6. Concho County also sets no zoning-based minimum dwelling size or setback on unincorporated land6.
Wastewater remains regulated even when the dwelling type is not restricted by county zoning. Septic systems and holding tanks generally require approval, while the state's acreage exemption applies only when every listed condition is satisfied17. The Concho County OSSF Program serves locations outside incorporated cities, so call that office before planning an RV hookup or tiny-home wastewater system11. No separate county certificate-of-occupancy or utility-connection rule could be confirmed. Ask the County Judge / Commissioners Court about current practice, and verify city rules separately if the parcel is within municipal limits8.
Building a home in Concho County: the steps, in order
- Confirm that the parcel is outside an incorporated city; the county permit and zoning answers here apply to unincorporated Concho County12.
- Call the Concho County OSSF Program before septic design or installation, and determine whether the state acreage exemption actually fits the tract114.
- Locate the parcel relative to Hickory Underground Water Conservation District No. 15. Within the district's part of Concho County, submit a Notice of Intent before drilling any well; non-exempt wells need a permit before drilling5.
- If access will connect to a Texas state highway, contact the local TxDOT district and submit Form 1058 before work in the right of way13.
- Ask the County Judge / Commissioners Court whether any parcel-specific floodplain or county process applies, because a published county floodplain-development rule could not be confirmed8.
What should you check before buying land in Concho County?
Start with water and septic feasibility. Only about 9% of Concho County soils are rated without severe limitations for a conventional drain field, annual precipitation is about 25 inches, and severe drought occurs in roughly 19% of years161819. Parts of Concho County lie inside Hickory Underground Water Conservation District No. 1, where every well needs a Notice of Intent and non-exempt wells need permits5.
The terrain is mostly gentle, with about 97% of land at a slope of 15% or less, but legal access still needs verification20. A driveway onto a state highway requires the TxDOT process13. Concho County is sparsely settled at about 3.4 people per square mile, and the nearest city of 100,000 or more is about 82 miles from the county center2122. The typical effective property-tax rate is about 1.5%, with a median annual bill near $1,6002324.
Watch-outs
- A septic acreage exemption is not automatic: every state condition, including the site evaluation and property-line separation, must be met4.
- Hickory Underground Water Conservation District rules apply only in its portion of Concho County, so confirm the parcel boundary before planning a well5.
- No official Concho County floodplain-development rule was confirmed; ask the County Judge / Commissioners Court before building in or near mapped flood hazard areas8.
