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

58Index Score / 100
#99 of 254 in Texas

Unincorporated Uvalde County, Texas does not appear to require a building permit and has no zoning ordinance, so county zoning does not restrict RVs, tiny homes, manufactured homes or setbacks123. Inside the City of Uvalde, the city has adopted the 2021 International Building Code and issues building permits, and it has its own zoning map and code45. Septic permits for every address in the county, city or not, come from the county Sanitation Office6, and water-well authority depends on the aquifer beneath the parcel7.

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

Unincorporated Uvalde County does not appear to require a building permit: the county has no building or inspection department, and its own office list names a Sanitarian but no building official1. Do not apply that answer inside the City of Uvalde: the city adopted the 2021 International Building Code, including specified appendices, and its ordinance provides for permits and fees4. Texas Local Government Code Chapter 233 gives counties only narrow, specific building-permit powers: the optional fire code requires a county population over 250,000 or being adjacent to one, and Uvalde County's population of about 24,960 falls well short of that threshold on its own1011. Even where a county adopts optional residential standards, manufactured and modular structures are excluded from them10. One thing we could not confirm: Texas lets a county opt in to residential inspections under Local Government Code Chapter 233, Subchapter F by resolution or order, and we found no sign that Uvalde County has done so12. Ask the County Clerk whether the Commissioners Court has adopted one13.

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

Uvalde County's own office list includes the County Clerk, County Commissioners, County Judge, Road Department, and Sanitation Office, but no building, planning, or zoning department12. For septic and private-well guidance, contact the Sanitation Office at 66 Military Lane, Box 9, Uvalde, Texas 78801, phone (830) 900-655814. For plat filings, recording, and general county business, the County Clerk's office is at 100 N. Getty St, 1st Floor - Courthouse, Uvalde, TX 78801, phone (830) 278-661413. Uvalde County's own site does not publish a driveway-access permit requirement for county roads, so confirm directly with the Road Department at 2967 US Hwy 83 N, Uvalde, TX 78801, phone (830) 278-9213, before you build a new approach onto one15.

Does Uvalde County have zoning?

Unincorporated Uvalde County has no zoning ordinance, and like nearly all Texas counties, has no general power to adopt one2. Because there is no county zoning ordinance, there is no minimum lot size, setback rule, height limit, or dwelling-size minimum in unincorporated Uvalde County, and RVs, tiny homes, manufactured homes, and accessory dwellings are unrestricted by county zoning3. City limits matter: the City of Uvalde has adopted the 2021 International Building Code and a permit-and-fee system, and it points to its own zoning map and zoning code for allowed uses, so the unincorporated-county answer does not govern construction or land use inside the city45. Septic stays with the county Sanitation Office either way6. Qualifying agricultural or timber land can still get a lower property-tax appraisal, unrelated to zoning, once it has been in agricultural use for at least 5 of the past 7 years16.

How do septic and water well permits work in Uvalde County?

Any onsite sewage facility (OSSF) in Uvalde County needs a permit before you build it, issued by the county's own Sanitation Office, which publishes the OSSF application and a step-by-step permitting-process guide614. Statewide, Texas requires a permit and approved plan to construct, alter, repair, extend, or operate an OSSF, though a 10-acre exemption can apply if a licensed site evaluation is done, the tract holds only a single-family home, every part of the system sits at least 100 feet from the property line, and effluent stays on your own property17. Soils are a real constraint here: only about 5.3% of Uvalde County's land is rated without severe limits for a conventional drain field, so budget for a site evaluation and possibly an engineered system rather than counting on the cheapest option8. Water wells fall under the Uvalde County Underground Water Conservation District, which shares the county's boundaries and has adopted its own permitting rules, except within the Edwards Balcones Fault Zone aquifer area, which the Edwards Aquifer Authority regulates instead7.

Can you live in an RV or tiny home on your land in Uvalde County, Texas?

Unincorporated Uvalde County has no zoning ordinance, so there is no county rule against living in an RV, tiny home, or manufactured home on your own land3. That does not remove the septic requirement: whatever you live in, if it is not on a public sewer you still need a permitted OSSF, or you need to qualify for the state's 10-acre exemption, before you can legally use a toilet there617. Factory-built industrialized housing, as distinct from an ordinary manufactured or mobile home, still has to meet Texas's mandatory building, plumbing, and electrical codes for construction beginning on or after July 1, 2024, regardless of county zoning18.

How do you build a home in Uvalde County, step by step?

  1. Confirm your septic plan with the Sanitation Office (66 Military Lane, Box 9, Uvalde, Texas 78801; (830) 900-6558), or check whether your tract of 10 acres or more qualifies for the state's septic-permit exemption instead1417.
  2. If you don't qualify for the exemption, get a site evaluation from a licensed evaluator; only about 5.3% of Uvalde County's soils are rated free of severe limits for a conventional drain field, so this step matters8.
  3. If you're drilling a well, check with the Uvalde County Underground Water Conservation District about its permitting rules, and confirm whether your property sits inside the separately regulated Edwards Aquifer zone7.
  4. Submit your OSSF application and permitting-process paperwork to the Sanitation Office and wait for approval before you build146.
  5. If you're platting or subdividing your tract, first have the County Judge accept the application, then deliver a copy to the County Clerk so the fee can be calculated; pay the application fee promptly, and pay the plat-record fee after final approval by Commissioners Court1913. Plat fees run $1,000 plus $100 per lot with roads, or $500 plus $50 per lot without roads; the county process does not apply when a city approves a plat wholly within its jurisdiction20.
  6. If your driveway will connect to a state highway, apply for a TxDOT access driveway permit on Form 1058 before you build it; Uvalde County's own site does not publish a separate permit requirement for driveways onto county roads, so ask the Road Department directly2115.
  7. Build: unincorporated Uvalde County has no confirmed building-permit or inspection requirement, so no county sign-off is needed to start construction on an ordinary site-built home1. Inside the City of Uvalde, follow the city's adopted building code and permitting system instead4.

What should you check before buying land in Uvalde County?

Septic: get a site evaluation before you buy, since only about 5.3% of Uvalde County's soils are rated without severe limits for a conventional drain field, and check whether your tract is 10 acres or larger, which could qualify you for the state's septic-permit exemption817. Water: confirm whether your parcel sits inside the Edwards Balcones Fault Zone aquifer area, since well permitting there goes through the Edwards Aquifer Authority instead of the county's own Underground Water Conservation District7. Zoning: there is none in unincorporated Uvalde County, and Texas law gives the county no path to adopt it outside a short list of specific places elsewhere in the state222. Taxes: Uvalde County's effective property tax rate runs about 1.6%, with a median annual property tax bill around $2,260, and qualifying agricultural or timber land can get a lower productivity-value appraisal instead232416. Climate and setting: this is dry country, with about 25.7 inches of rain a year and severe drought in roughly 39.9% of years historically, a population density of about 16.1 people per square mile, and the nearest city of 100,000 or more people about 75 miles away in a straight line25262728.

Watch-outs

  • We could not confirm any driveway-access permit requirement for Uvalde County roads (as opposed to state highways, which need a TxDOT Form 1058 permit); ask the Road Department before you cut a new approach1521.
  • Uvalde County's own site does not state whether an owner-builder exemption applies to septic installation; ask the Sanitation Office directly rather than assume one exists914.
  • We could not confirm whether Uvalde County has adopted any building-inspection, certificate-of-occupancy, or short-term-rental rule; the county's own website does not publish any of these, so ask the County Clerk's office directly113.
