Building permits, zoning and land rules in Deaf Smith County, Texas

Deaf Smith County does not publish a county-specific answer on permits for an ordinary home in an unincorporated area, and the reviewed state permit provision applies only to specified buildings where the relevant county fire-code subchapter applies². The county also has not confirmed adoption of the state residential-inspection framework, which applies only after a county adopts it by resolution or order². Before building, ask the County Judge's office to confirm the parcel's jurisdiction and any permit, inspection or floodplain requirement³. Inside Hereford, the Building and Zoning Department reviews plans, issues permits and inspects construction within city limits⁴. Hereford has also adopted the 2018 International Building Code¹³.

Deaf Smith County does not identify a dedicated building or zoning department for unincorporated construction⁷. Hereford's Building and Zoning Department handles building permits and zoning inside the city, while septic permits stay with the county^4,5. For confirmation of a rural building permit, inspection or floodplain requirement, start with the County Judge's office at 235 E 3rd St, Hereford, TX 79045, or call 806-363-7000³. Deaf Smith County is the local OSSF permitting authority, and the County Clerk's Office provides the septic application and fee schedule^5,14. The Clerk's Office is at 235 East 3rd Street, Room 203, Hereford, TX 79045, and its phone number is 806-363-7077¹⁴. Published OSSF fees are $310 residential, $410 commercial, $50 for reinspection and $100 for a complaint or investigation⁸. TxDOT handles access connecting to a state highway¹¹.

Unincorporated Deaf Smith County has no county zoning ordinance^1,7. County zoning therefore sets no minimum dwelling size, minimum lot size, setback, lot-coverage limit or building-height limit there¹. County zoning also does not restrict accessory dwellings, RV occupancy, tiny-home occupancy, manufactured-home occupancy or temporary camping on unincorporated land¹. Septic, well, highway-access and subdivision rules remain separate questions^6,9,10,15. Hereford is different: the city has its own zoning ordinance, and its Building and Zoning Department handles construction within city limits⁴. Ask Hereford to verify jurisdiction for land on or near the city boundary.

Deaf Smith County is the local permitting authority for on-site sewage facilities⁵. A permit and approved plan are generally required before an OSSF is built, altered, repaired, extended or operated⁶. Installation inspections follow the Texas minimum standard, carried out by the local authorized agent, and the county fee schedule lists a reinspection charge¹⁶. Apply through the County Clerk and do not begin construction before receiving authorization^14,17. A residential permit costs $310, a commercial permit $410, reinspection costs $50 and a complaint or investigation costs $100⁸. Only about 29.6% of county soils avoid severe limits for a conventional drain field, so make septic suitability part of due diligence¹². A narrow exemption may apply to a single-family tract of at least 10 acres when every OSSF part is at least 100 feet from the property line and the other state conditions are met⁶.

County zoning does not restrict RV, tiny-home, manufactured-home or temporary-camping occupancy on unincorporated land in Deaf Smith County¹. That answer is limited to zoning: wastewater generally still needs OSSF authorization from Deaf Smith County^5,6. Within the part of Deaf Smith County served by the High Plains Underground Water Conservation District, a well expected to produce 17.5 gallons per minute or more needs a permit before drilling and production, with a $250 fee for an Ogallala or Dockum well permit⁹, while a well producing less than 17.5 gallons per minute is exempt¹⁸; we could not confirm the well rule outside district territory⁹. Inside Hereford, city zoning and building-code enforcement apply within city limits, so the unincorporated answer above does not carry over⁴. For an RV or tiny home near the boundary, ask Hereford to verify city jurisdiction and ask the County Clerk how to permit the proposed wastewater system¹⁴.

1. Confirm whether the parcel is inside Hereford; city zoning applies and the city handles permits and inspections within city limits⁴.
2. For unincorporated land, ask the County Judge's office whether the project triggers any county permit, inspection or floodplain approval because a county-specific ordinary-home rule was not confirmed^2,3.
3. Apply through the County Clerk before installing an OSSF; the residential permit fee is $310^5,6,8,14.
4. Confirm whether the site lies in HPWD territory. There, wells expected to produce at least 17.5 gallons per minute require a permit before drilling⁹.
5. For state-highway access, submit TxDOT Form 1058, obtain the executed permit and give 24 hours' notice before right-of-way work¹¹.
6. If dividing unincorporated land, confirm whether a plat is required; qualifying agricultural, farm, ranch, wildlife-management or timber-production divisions may be exempt while that use continues^15,19.

Confirm water, septic suitability, access, floodplain status and subdivision history before buying. Only about 29.6% of Deaf Smith County soils avoid severe limits for a conventional drain field¹². Within HPWD territory, a well expected to produce at least 17.5 gallons per minute needs a permit before drilling and production; we could not confirm the applicable rule outside HPWD territory⁹. State-highway driveways need TxDOT approval¹⁰. Dividing unincorporated land into two or more parts generally triggers state platting rules, subject to statutory exceptions including a conditional agricultural-use exemption^15,19. Typical annual home insurance is about $2,324, the effective property-tax rate about 1.4%, and the median annual property-tax bill about $1,590¹².
