Upton County, TX Building Permits, Zoning & Septic

Unincorporated Upton County, Texas has no general building-permit requirement for single-family homes and no county zoning ordinance, because Texas law limits county building authority to commercial and multifamily structures in large counties and gives most counties no zoning power at all.¹² Septic (OSSF) systems still need a permit, and Upton County is itself the TCEQ-authorized agent for on-site sewage permitting in the unincorporated county.³ A statewide $75 owner-installation permit is available if you buy industrialized or manufactured housing and install it yourself.⁴⁵

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

Unincorporated Upton County has no general building-permit requirement for single-family homes: Texas Local Government Code Chapter 233 limits county building-permit authority in unincorporated areas to commercial, public and multifamily structures, not ordinary single-family construction.¹ Only a county over 250,000 people (or adjacent to one) may adopt a fire-code permit at all, and Upton County, with about 3,109 residents, falls well short of that threshold.⁶⁹ One exception matters if you're installing prefabricated housing: a person who buys industrialized housing or a building for their own use and takes responsibility for the installation can file a $75 state installation permit instead of registering as a builder.⁴⁵

Who handles septic and county permits in Upton County, and how do you reach them?

The Upton County Judge and Commissioners Court, based at the county courthouse, are the general contact for county government functions, including questions about where to take a septic or other county-level application.¹⁰ Reach the office at 432-693-2321, or at 205 E. 10th Street, Rankin, TX 79778.¹⁰ TCEQ's own authorized-agent lookup lists Upton County as the OSSF authorized agent for the unincorporated county, but the county's website does not publish a separate sanitation or environmental-health department page, so call the County Judge's office to confirm exactly who processes septic applications today.³¹⁰

Does Upton County have zoning?

Unincorporated Upton County has no county zoning ordinance: Texas law gives counties zoning power only in a handful of specific situations, such as parts of Padre Island and a few named lakes and military zones, and Upton County is not one of them.⁷ Because the county has no zoning authority over unincorporated land, it sets no minimum lot size, no setbacks, no lot-coverage limit, no building-height limit and no zoning districts, and RVs, tiny homes and manufactured homes are unrestricted by county zoning.² That is a real answer, not a research gap: it follows directly from Texas law giving a county like Upton no general zoning power.²

How do septic (OSSF) permits work in Upton County?

Every on-site sewage facility in Texas needs a permit and an approved plan before construction, alteration, repair or extension, with one narrow exception.¹¹ The exception is a "10-acre rule": a single-family home on at least 10 acres, evaluated by a licensed site evaluator or professional engineer, with every part of the OSSF at least 100 feet from the property line, no other dwelling on the tract, and no nuisance or groundwater pollution.¹¹ Unlike some of its rural Texas neighbors, Upton County itself is TCEQ's designated authorized agent for OSSF permits in the unincorporated county, rather than defaulting to a TCEQ regional office.³ The permitting authority must approve or deny a complete application within 30 days, and the installer must give at least five working days' notice before the required construction inspection.¹²¹³ A few sanitation methods are off-limits statewide: boreholes, cesspools and seepage pits are prohibited, and any system treating more than 5,000 gallons a day needs a different permit entirely.¹⁴ With 46.1% of Upton County's soils free of severe limits for a conventional septic drain field, a standard system is workable on much of the land here.¹⁵

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

Yes, with conditions: unincorporated Upton County has no zoning ordinance, so it sets no rule restricting RV, tiny-home or manufactured-home occupancy on private land, a direct result of Texas law giving the county no general zoning power.² The same lack of zoning means there is no minimum dwelling size and no accessory-dwelling rule in unincorporated Upton County.² Any wastewater system connected to the RV, tiny home or manufactured home still needs an OSSF permit through Upton County's own TCEQ-authorized program.³¹¹ If you're installing a manufactured or industrialized structure and doing the installation work yourself, the state's $75 owner-installation permit may apply instead of registering as a builder.⁵

Building on land in Upton County: the steps, in order

Confirm whether the parcel is inside an incorporated city such as Rankin or McCamey; this guide covers unincorporated Upton County, where the county itself has no zoning.⁷
Call the County Judge's office at 432-693-2321 to confirm who currently processes septic applications, since the county has no separate sanitation department listed online.¹⁰³
Get your OSSF plan approved and permit issued before construction; expect a decision within 30 days of a complete application.¹²
Give the permitting authority at least five working days' notice before the required installation inspection.¹³
If you're installing industrialized or manufactured housing yourself, file the state's $75 owner-installation permit instead of registering as a builder.⁵
No county building permit or inspection has been confirmed as required for ordinary single-family construction in unincorporated Upton County, consistent with Texas's limits on county building authority.¹⁶
If your driveway will connect to a state highway, file TxDOT Form 1058 and give 24 hours' notice to TxDOT before construction.¹⁶

What to check before you buy land in Upton County, Texas

Soils give you decent odds: 46.1% of Upton County has soils without severe limits for a conventional septic drain field.¹⁵ The county is flat and dry -- 97.3% of land sits at 15% slope or less, almost no tree cover at 0.2% wooded, and severe drought in about 22.3% of years.¹⁷¹⁸¹⁹ Upton County is rural and sparsely populated, with 3,109 residents at about 2.5 people per square mile, roughly 40 miles from the nearest metro area.⁹²⁰²¹ Texas has no statewide permit requirement to drill a private water well, though local groundwater-conservation-district rules can still apply, so ask before you drill.⁸ Property taxes run an effective 1.1% rate, with a median annual bill of $1,197.²²²³

Watch-outs

Upton County's website has no dedicated sanitation or environmental-health department page even though TCEQ lists the county as its own OSSF authorized agent; call the County Judge's office to find out who currently handles applications.³¹⁰
Texas's 10-acre OSSF exemption is easy to misread: every condition (site evaluation, single-family use, 100-foot setback, no other dwelling) must be met, not just the acreage.¹¹
No official record confirms floodplain-development, county driveway-access, or short-term-rental rules for unincorporated Upton County; treat those as unconfirmed and ask the County Judge's office directly.¹⁰

- Partial — State-mandated building energy-code minimums applicable statewide, including single-family homes and other residential, commercial, and industrial buildings in Upton County.
  “The minimum state-mandated code for single-family homes is Chapter 11 of the 2015 International Residential Code. The applicable code for other residences and commercial and industrial buildings is the 2015 International Energy Conservation Code. These energy codes are effective statewide. Texas is a "home rule" state, however, allowing local jurisdictions to adopt amendments to the codes. To amend the state code in non-attainment and affected counties, Energy Systems Laboratory at Texas A&M University at the request of a municipality or county must first determine whether the amended code is as stringent as existing state codes. Code changes that are determined to be as stringent or more stringent than state code may be adopted as a local rule. Local jurisdictions are responsible for building energy code implementation and enforcement.”
