Do you need a building permit 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 adoption12. Kress applies a housing code within Kress, and Tulia regulates zoning and development within Tulia1314. 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 adopted15. Separate septic, well and state-highway driveway approvals can still apply51016.
Who handles building and land permits in Swisher County?
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 confirm17. 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 exists678. High Plains Underground Water Conservation District handles a well expected to produce at least 17.5 gallons per minute10. A state-highway driveway goes through TxDOT rather than the county16. Inside a municipality, contact the city because Kress and Tulia have their own rules1314.
Does Swisher County have zoning?
Unincorporated Swisher County has no county zoning ordinance2. 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 camping3. 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 use18. A qualifying agricultural, farm, ranch, wildlife-management or timber-production division can be exempt, but platting applies if that qualifying use ends19. Tulia regulates zoning and development inside Tulia, while Kress has housing standards inside Kress1413. 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 answer4.
How do septic permits work in Swisher County?
A permit and approved plan are generally required to construct, install, alter, extend or repair an OSSF in Swisher County5. Start with TCEQ Region 1 in Amarillo; the office covers Swisher County and administers OSSF permits where no approved local program exists678. The permitting authority must decide on the application and planning materials within 30 days5. When TCEQ administers the permit, the fee is $200 for a single-family OSSF or $400 for another OSSF, plus $109. Only 11.1% of county soils lack severe limits for a conventional drain field, so budget for an early site evaluation11. 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 condition20. Listed emergency repairs instead require written notice within 72 hours after work begins20.
Can you live in an RV or tiny home in Swisher County?
Unincorporated Swisher County has no county zoning rule restricting RV living, tiny-home occupancy, manufactured-home occupancy or temporary camping3. County zoning also sets no minimum dwelling size or minimum lot size there3. Septic systems and holding tanks generally require an approved OSSF plan and permit, subject to narrow exceptions2120. A well expected to produce at least 17.5 gallons per minute requires an HPWD permit before drilling and production10. The conditional state owner-builder provision does not waive inspections, building standards, septic rules or other permit requirements15. Ask the County Judge's office about inspection and occupancy procedures before placing a structure17. Properties inside Tulia or Kress need city review1413.
Building a home in Swisher County: the steps, in order
- Confirm that the parcel is outside Tulia, Kress and any other municipality before using the unincorporated-county answers1413.
- Ask the County Judge's office about floodplain development, inspections and occupancy approval because those details could not be confirmed17.
- Confirm that a divided tract was platted when required or still qualifies for the agricultural-use exception1819.
- Obtain an HPWD permit before drilling a well expected to produce at least 17.5 gallons per minute10.
What should you check before buying land in Swisher County?
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 limits222311. Ask a well professional about expected yield and whether the 17.5-gallon-per-minute HPWD permit threshold applies10. 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 county2425. Verify legal access and whether a state-highway driveway needs TxDOT approval16. If the parcel was split from a larger tract, confirm the plat or a valid, continuing agricultural-use exception1819. The effective property-tax rate is about 1.7%, and the median annual property-tax bill is about $1,5552627.
Watch-outs
- Swisher County-specific building inspections and certificates of occupancy could not be confirmed; the state owner-builder provision is not a general waiver, so ask the County Judge's office before starting work1517.
- Tulia and Kress have municipal rules that do not apply to unincorporated Swisher County, so verify the parcel's jurisdiction first1413.
- A new or modified driveway connecting to a Texas state highway requires an executed TxDOT access permit before construction in the right of way16.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO).
