Unincorporated Reeves County, Texas has no general residential building permit or zoning ordinance, because Texas counties lack that authority outside a handful of narrow statutory exceptions12. The county's Road & Bridge Department still requires its own permits for specific things: driveways and culverts, utility lines in county rights-of-way, on-site sewage (septic) systems, manufactured-home rental communities and new subdivisions3. Septic permits are issued locally, by the county's own Health Inspector as a TCEQ-authorized agent, not by a state regional office4.

Do you need a building permit in Reeves County, Texas?
No general one. Texas counties can't require a residential building permit or adopt a general building code outside a short list of statutory exceptions, and Reeves County doesn't meet them1. One of those exceptions lets a county adopt its own fire code, but only if it has more than 250,000 residents or is adjacent to one that does, and even then only for commercial buildings, public buildings and multifamily dwellings of four or more units - Reeves County, with roughly 11,770 residents, is nowhere close1011. That said, Reeves County isn't a hands-off county: its Road & Bridge Department runs its own permit program covering driveways and culverts, utility lines placed in county rights-of-way, on-site sewage (septic) systems, manufactured-home rental communities and new subdivisions312. If your project touches any of those, you still need a county permit even though there's no permit for the house itself.
Who is the Reeves County Road & Bridge Department, and how do you reach them?
Reeves County's permits, regulations and policies are handled out of the Road & Bridge Department, reachable at 432-448-0724, with an online portal for applications12. As of January 1, 2026, all original permit applications must be mailed to the county's Treasurer's Office at 1714 Schmidt Drive, Pecos, TX 79772, rather than dropped off in person, so plan for mailing time12. Septic (OSSF) applications go through the same department's Health Inspector, at 432-448-119313. Call before you buy materials or start work: a driveway, culvert, utility line or septic system installed without the matching county permit is exactly the kind of thing this office is set up to catch.
Does Reeves County have zoning?
No. Reeves County has no published zoning ordinance in unincorporated areas, and Texas's county zoning statute grants that power only to a short, specific list of counties tied to particular geographic features - Reeves County isn't one of them12. Because the county has no zoning districts, it sets no minimum dwelling size, no minimum lot size, no setbacks, no lot-coverage limit and no building-height limit, and doesn't restrict RVs, tiny homes, manufactured homes or accessory dwellings as a land use through zoning5. That's a separate question from the county's driveway, utility, septic and subdivision permits above, which apply regardless of zoning12.
How do septic permits work in Reeves County?
Septic systems in Reeves County are permitted locally: the county's own Health Inspector, working out of the Road & Bridge Department, is the TCEQ-authorized agent for on-site sewage facilities (OSSFs) here, rather than a TCEQ regional office413. Statewide, a permit and approved plan are required to construct, alter, extend or repair an OSSF, though a single-family home on at least 10 acres can qualify for an exemption if a licensed site evaluator confirms no nuisance or groundwater risk, every part of the system sits at least 100 feet from the property line, and the home is the only dwelling on the tract14. Soils are the thing to plan around here: only about 22% of Reeves County's land has no severe limits for a conventional drain field, so get a site evaluation early and budget for an alternative system if yours comes back limited7. Installation is inspected either directly or through a maintenance provider's reporting, which can drop to every six months if the system uses qualifying electronic monitoring15.
Can you live in an RV or tiny home on your land in Reeves County?
Reeves County's lack of zoning districts means county zoning doesn't restrict occupying an RV, tiny home or manufactured home on your own unincorporated land5. Don't confuse that with the county's manufactured-home rental community regulations, which is a distinct permit process aimed at anyone operating a community of manufactured homes for rent, not at a single owner living on their own tract12. Whatever you place still needs to handle sewage through a permitted septic system or a connection to service, since that permit runs through the state regardless of zoning414. If you're unsure which category your plans fall into, call the Road & Bridge Department before you move anything onto the land12.
Building on land in Reeves County: the steps, in order
- Confirm your parcel is unincorporated Reeves County, not inside Pecos, Balmorhea or another town, since town rules differ from the county's1.
- Call the Road & Bridge Department at 432-448-0724 to find out which of its permits (driveway/culvert, utility, subdivision) your project needs12.
- If you're adding or changing a driveway or culvert, get that county permit before construction, separate from anything the state requires12.
- Apply for an OSSF (septic) permit through the county Health Inspector, and ask up front whether your tract qualifies for the state's 10-acre exemption1314.
- Mail your original application materials to the county Treasurer's Office at 1714 Schmidt Drive, Pecos, TX 79772, under the rule effective January 1, 202612.
- If your access is instead from a state highway, apply separately to the local TxDOT district office using Form 1058 before building the driveway16.
