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

Unincorporated Swisher County does not require a general county building permit¹. Texas law provides a conditional county fire-code permit framework for commercial buildings, public buildings and multifamily buildings with four or more units, but only for a qualifying county that adopts it; we could not confirm a Swisher County adoption⁹. Kress applies a housing code within Kress, and Tulia regulates zoning and development within Tulia^3,10. The state owner-builder provision does not waive a permit or inspection; it is a penalty exception under a separately adopted residential-code framework, which we could not confirm Swisher County has adopted⁹. Separate septic, well and state-highway driveway approvals can still apply^4,7,11.

Swisher County does not have a general county building-permit department for unincorporated homes¹. Start with the Swisher County Judge's office for county-specific questions about floodplain development, inspections, occupancy approval or land division that we could not confirm¹². For septic permits, start with the TCEQ Region 1 office in Amarillo; the regional office covers Swisher County and administers OSSF permits where no approved local program exists^4,5,6. High Plains Underground Water Conservation District handles a well expected to produce at least 17.5 gallons per minute⁷. A state-highway driveway goes through TxDOT rather than the county¹¹. Inside a municipality, contact the city because Kress and Tulia have their own rules^3,10.

Unincorporated Swisher County has no county zoning ordinance¹. County zoning therefore sets no minimum dwelling size, minimum lot size, setback, lot coverage or building-height limit on unincorporated land, and it does not restrict RV living, tiny-home occupancy, manufactured homes, accessory dwellings or temporary camping². Other rules still matter. Texas platting law requires a plat for specified divisions outside a municipality, including divisions laying out lots, a subdivision or areas intended for public use¹³. A qualifying agricultural, farm, ranch, wildlife-management or timber-production division can be exempt, but platting applies if that qualifying use ends¹⁴. Tulia regulates zoning and development inside Tulia, while Kress has housing standards inside Kress^3,10. We could not confirm zoning rules for Happy or any other place in the county, so ask that city before relying on the unincorporated-county answer³.

A permit and approved plan are generally required to construct, install, alter, extend or repair an OSSF in Swisher County⁴. Start with TCEQ Region 1 in Amarillo; the office covers Swisher County and administers OSSF permits where no approved local program exists^4,5,6. The permitting authority must decide on the application and planning materials within 30 days⁴. When TCEQ administers the permit, the fee is $200 for a single-family OSSF or $400 for another OSSF, plus $10⁵. Only 11.1% of county soils lack severe limits for a conventional drain field, so budget for an early site evaluation⁸. The 10-acre single-family exemption requires a licensed site evaluation, at least 100 feet between every system part and the property line, on-tract effluent disposal and every other listed condition⁴. Listed emergency repairs instead require written notice within 72 hours after work begins⁴.

Unincorporated Swisher County has no county zoning rule restricting RV living, tiny-home occupancy, manufactured-home occupancy or temporary camping². County zoning also sets no minimum dwelling size or minimum lot size there². Septic systems and holding tanks generally require an approved OSSF plan and permit, subject to narrow exceptions⁴. A well expected to produce at least 17.5 gallons per minute requires an HPWD permit before drilling and production⁷. The conditional state owner-builder provision does not waive inspections, building standards, septic rules or other permit requirements⁹. Ask the County Judge's office about inspection and occupancy procedures before placing a structure¹². Properties inside Tulia or Kress need city review^3,10.

1. Confirm that the parcel is outside Tulia, Kress and any other municipality before using the unincorporated-county answers^3,10.

1. Ask the County Judge's office about floodplain development, inspections and occupancy approval because those details could not be confirmed¹².

1. Confirm that a divided tract was platted when required or still qualifies for the agricultural-use exception^13,14.

1. Obtain an HPWD permit before drilling a well expected to produce at least 17.5 gallons per minute⁷.

1. Get the septic site evaluation and submit the OSSF application and plans before installation unless every exemption condition applies⁴.

1. If access will connect to a state highway, obtain the executed TxDOT permit before work¹¹. Then proceed without a general Swisher County building permit¹.

Water and septic feasibility deserve early attention. Swisher County averages about 20 inches of precipitation a year, severe drought occurs in 40.5% of years, and only 11.1% of soils lack severe conventional drain-field limits⁸. Ask a well professional about expected yield and whether the 17.5-gallon-per-minute HPWD permit threshold applies⁷. The terrain is broadly gentle, with 99.8% of land at a slope of 15% or less, while forest covers just 0.1% of the county⁸. Verify legal access and whether a state-highway driveway needs TxDOT approval¹¹. If the parcel was split from a larger tract, confirm the plat or a valid, continuing agricultural-use exception^13,14. The effective property-tax rate is about 1.7%, and the median annual property-tax bill is about $1,555⁸.
