#121 of 254 in Texas

Unincorporated Starr County, Texas does not require a building permit for a home, and the county has no zoning ordinance, so there's no minimum home size, setback rule, or restriction on RVs, tiny homes, or manufactured homes123. A septic system generally needs an approved plan and permit, but the permitting authority must be confirmed for the property because Texas uses both local authorized agents and TCEQ regional offices45. A tract of 10 acres or more may qualify for an exemption if every condition is met5.

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

No: unincorporated Starr County does not require a building permit for a home, barn, shed, or workshop1. Texas counties generally have no authority to require residential building permits in unincorporated areas, and the narrow county fire-code and residential-code powers Texas law does allow only apply to counties over 250,000 people (or adjacent to one) for the fire code, or counties that have separately adopted a residential-code resolution17. Starr County's population of roughly 66,000 does not clear the 250,000 fire-code threshold, and no official Starr County resolution adopting the residential-code option was found78.

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

Starr County has no building or zoning department, and its own navigation menu names only the county judge, commissioners court by precinct, county attorney, county clerk, county treasurer, tax assessor-collector, constables, sheriff, justice of the peace, county auditor, and several administrative offices9. For septic, start with the listed Starr County OSSF contact, but confirm that it is the applicable permitting authority for the property before filing because Texas uses local authorized agents where TCEQ has approved a local program and a TCEQ regional office elsewhere104. For anything else county government handles, including roads, the county judge's office at the courthouse, 401 N. Britton Ave, Rio Grande City, TX 78582, phone (956) 716-4800, is the place to start9.

Does Starr County have zoning?

Starr County has no zoning ordinance and, as a Texas county without special legislative authorization, cannot adopt one for unincorporated land2. Texas gives counties zoning power only for a short list of specific places named in state law, like parts of Padre Island, the Amistad Recreation Area, and a few named lakes, and Starr County is not one of them11. Because there is no county zoning ordinance, there is no minimum lot size, setback rule, height limit, or dwelling-size minimum, and RVs, tiny homes, manufactured homes, and accessory dwellings are unrestricted by county zoning3.

How do septic permits work in Starr County?

A permit and approved plan are generally required before constructing, altering, repairing, extending, or operating an on-site sewage facility in Starr County5. Confirm the permitting authority for the property before filing: TCEQ oversees the statewide program, approved local governments may administer it, and the TCEQ regional office handles locations without an authorized local jurisdiction4. The authorized agent or its designated representative reviews plans, issues permits, and inspects system installation; later maintenance-provider inspections apply only where the system and rules require them, and local requirements may be stricter12. A single-family home on at least 10 acres may qualify for an exemption only if every condition is met, including a licensed site evaluation, no nuisance or groundwater pollution, at least 100 feet between every system part and the property line, on-property effluent disposal, and no other dwelling on the tract5. About 49% of Starr County's soils are rated without severe limits for a conventional drain field, so evaluate the site before choosing a system6.

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

Unincorporated Starr 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 isn't on a public sewer you still need a permitted OSSF, or you need to qualify for the 10-acre exemption, before you can legally use a toilet there5. A factory-built structure sold as "industrialized housing" (as opposed to an ordinary manufactured/mobile home) has to meet Texas's mandatory 2021-edition building codes regardless of county zoning13.

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

  1. Confirm whether the parcel is inside a municipality or in unincorporated Starr County because the responsible offices can differ4.
  2. Contact the listed Starr County OSSF office and ask it to confirm the permitting authority for the parcel before submitting plans104.
  3. Determine whether a single-family tract of at least 10 acres meets every condition for the septic-permit exemption; otherwise arrange the required site evaluation and planning5.
  4. Submit the OSSF plan and permit application to the confirmed authority, then arrange the installation inspection required through the authorized agent or its designated representative512.
  5. If the driveway will connect to a state highway, apply for a TxDOT access driveway permit on Form 1058 before building it14.
  6. Build: unincorporated Starr County does not require a county building permit for an ordinary site-built home1.
  7. Ask the county judge's office about county matters not covered by a named office9.

What to check before you buy land in Starr County

Septic: get a site evaluation before you buy, since only about 49% of the county's soils are rated without severe limits for a conventional drain field, and find out whether your tract is large enough (10 acres or more) to qualify for the state's septic-permit exemption65. Access: a driveway onto a state highway needs a TxDOT permit on Form 1058, built to TxDOT's standards, with a typical farm or ranch driveway needing a 25-foot return radius and 20-foot throat width14. Zoning: there is none in unincorporated Starr County, and none is coming, since the county has no legal authority to adopt it211. Climate: expect hot summers, with severe drought in roughly a quarter of years and dozens of 100-degree days projected annually by mid-century1516. Taxes: Starr County's effective property tax rate runs about 1.1%, with a median annual property tax bill around $1,0471718. This is a more populated county than most on this list, at about 54 people per square mile, with the nearest metro area roughly 40 miles away1920.

Watch-outs

  • Starr County's former Groundwater Conservation District, which required permits for nonexempt wells, was dissolved and replaced by the Starr County Drainage and Groundwater Conservation District; we could not confirm the new district's current well-permit rules, so ask the county judge's office before drilling a well9.
  • Factory-built "industrialized housing," as distinct from an ordinary manufactured or mobile home, must meet Texas's mandatory building, energy, and electrical codes (2021-edition IBC/IRC with amendments) for construction starting on or after July 1, 2024, even though Starr County itself has no building-permit requirement13.
  • We could not confirm building-inspection requirements, certificate-of-occupancy rules, floodplain-development rules, or a short-term-rental ordinance for Starr County; the county's own website does not publish any of these, so ask the county judge's office directly rather than assume none exist1.
