Unincorporated Culberson County, Texas does not require a residential building permit and has no county building or planning department1. Culberson County also has no countywide zoning ordinance2.

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

No. Unincorporated Culberson County does not require a residential building permit1. The county's official website lists no building, inspection or permitting department among its government offices1, and Texas counties generally lack authority to require one outside a few narrow, population-gated exceptions8. Van Horn, the county seat, is Culberson County's only incorporated community, so if your land is inside Van Horn city limits rather than the surrounding unincorporated county, check with the city separately.

Who handles permitting questions in Culberson County?

There is no dedicated building or planning department in Culberson County1. For anything the county's own pages don't cover, the Culberson County Judge and Commissioners Court at the Culberson County Courthouse are the point of contact9. Reach them at (432) 283-2059 or 300 La Caverna St, Van Horn, TX 798559. A driveway onto a state highway is a separate process: contact the local TxDOT district office and file Form 1058 before you build it7.

Does Culberson County have zoning?

Culberson County has no countywide zoning ordinance2. Because Texas gives counties zoning power only in narrow, specifically named circumstances that do not include Culberson County, the county cannot set a minimum lot size, setbacks, a building height limit or zoning districts for unincorporated land6. That means unincorporated Culberson County has no zoning-based restriction on accessory dwellings or manufactured homes either6. Van Horn is the exception to check separately if your parcel sits inside city limits.

How do septic and well permits work in Culberson County?

Culberson County has no local health department or authorized agent listed for septic, so the Texas Commission on Environmental Quality's regional office is the OSSF permitting authority here rather than a county office310. A permit is required statewide to construct, install, alter, extend or repair an OSSF11, though a single-family home on a tract of at least 10 acres can qualify for Texas's 10-acre exemption if all TCEQ conditions are met, including keeping every part of the system at least 100 feet from the property line12. Only about 20% of Culberson County's mapped soils are free of severe limitations for a conventional septic drain field13, so get a site evaluation before you count on a standard system. Drilling most wells also needs a permit: the Culberson County Groundwater Conservation District requires a well-drilling permit before a non-exempt well is drilled, completed, equipped or altered, and even an exempt well needs a registration form45.

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

In unincorporated Culberson County, living in an RV or a tiny home on your own land is unrestricted, because the county has no zoning ordinance to set occupancy rules for either6. The same absence of zoning means Culberson County sets no minimum dwelling size for unincorporated land6. This is a county-level answer only: it does not apply inside Van Horn, and it says nothing about deed restrictions a particular subdivision may carry.

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

  1. Confirm your tract is in unincorporated Culberson County rather than inside Van Horn, since the city may set its own rules2.
  2. Because unincorporated Culberson County has no building permit or zoning requirement, you can generally start planning construction without a county permit12.
  3. Get a site evaluation and apply for your OSSF (septic) permit through TCEQ's regional office, since Culberson County has no local authorized agent311.
  4. If you'll drill a well, apply to the Culberson County Groundwater Conservation District for a well-drilling permit before drilling45.
  5. If your access road will connect to a state highway, apply to TxDOT for a driveway permit on Form 1058 through the local TxDOT district office before building the driveway7.
  6. For anything else, call the County Judge and Commissioners Court at (432) 283-20599.

What to check before you buy land in Culberson County

Check septic feasibility early: only about 20% of Culberson County's soils are free of severe limitations for a conventional drain field13, and the county averages just 11.4 inches of rain a year with roughly a third of years in severe drought1415, both relevant to any well you'll need to permit through the Groundwater Conservation District4. Culberson County is very sparsely populated, at about 0.6 people per square mile16, and sits roughly 119 miles from the nearest metro area17, so factor in distance for supplies, contractors and emergency services. Typical property tax runs about 0.9% of value, with a median annual bill near $7261819.

Watch-outs

  • Culberson County's own pages do not confirm whether the county has adopted the Chapter 233 resolution that would trigger residential building-code or inspection requirements; if unsure, ask the County Judge's office directly before you build98.
  • No official Culberson County page confirms an owner-builder exemption, a floodplain permit requirement, or subdivision platting rules for unincorporated land; call the County Judge's office to check before you buy or build9.
