Unincorporated Collingsworth County, Texas does not require a building permit for a home and has no county zoning ordinance1. Cities may set their own building-permit and zoning rules, while septic permits remain with the applicable OSSF authority and county-administered floodplain development requires a permit2,3.
Do you need a building permit in Collingsworth County, Texas?
No. Unincorporated Collingsworth County does not require a building permit to build a home.
No. Unincorporated Collingsworth County does not require a building permit to build a home1. A missing county building permit does not erase Texas energy standards: the statewide minimum for a single-family home is Chapter 11 of the 2015 International Residential Code, while the 2015 International Energy Conservation Code applies to other residences and commercial or industrial buildings10. Texas's county residential inspection framework applies only if a qualifying county adopts it by resolution or order, and we could not confirm a Collingsworth County adoption11. The framework does not require prior county approval before construction11. A septic permit generally remains necessary, and development in a county-administered mapped floodplain requires a floodplain development permit2,3. Incorporated municipalities may set their own building-permit rules; ask the city about building permits and zoning, and ask the applicable OSSF authority about septic permits.
Who issues building permits in Collingsworth County, and how do you reach them?
Unincorporated Collingsworth County has no county building permit to issue.
Unincorporated Collingsworth County has no county building permit to issue1. For parcel-specific county questions, contact the County Judge / Commissioners Court at 800 W. Avenue # 13, Wellington, TX 79095, phone 806-447-54085. We could not confirm a separate county building or zoning office. Inside an incorporated city, ask the city about its building permits and zoning approval; septic permits do not shift automatically to the city, so identify the applicable OSSF authority separately. TCEQ's OSSF Program can be reached at 512-239-3799 or ossf@tceq.texas.gov, and its contact page directs local permitting questions to the applicable authority12. County-administered mapped floodplain development also requires a floodplain development permit; ask the County Judge's office who handles that review3,5.
Does Collingsworth County have zoning?
No. Collingsworth County has no countywide zoning ordinance for unincorporated land.
No. Collingsworth County has no countywide zoning ordinance for unincorporated land1. Unincorporated Collingsworth County therefore has no county-set minimum dwelling size, minimum lot size, setback, lot coverage, building height, or zoning restriction on RVs, tiny homes, manufactured homes, accessory dwellings, or temporary camping on your own land6. No zoning does not mean no land-division rules: a rural owner dividing a tract into two or more parts for lots, a subdivision, or specified public uses generally must prepare a plat, subject to statutory exceptions7. A conditional exception covers qualifying divisions used primarily for agriculture, farming, ranching, wildlife management, or timber production, but platting requirements return if that qualifying primary use ends8. Ask the County Judge's office about any local subdivision order before splitting land5.
How do septic (OSSF) permits work in Collingsworth County?
Almost all septic systems need an OSSF permit before construction, installation, repair, extension, or alteration.
Almost all septic systems need an OSSF permit before construction, installation, repair, extension, or alteration2. Paid OSSF work must be done by a state-licensed person; a homeowner may work directly on the homeowner's own single-family residence2. A narrow exemption can apply to the only single-family dwelling on at least 10 acres after a licensed site evaluation, provided every system part is at least 100 feet from the property line, effluent stays on the property, and the system causes no nuisance or groundwater pollution13. For a permitted installation, the installer gives at least five working days' notice before the system is ready, and the permitting authority conducts the construction inspection4. The authorized agent sets OSSF permit and inspection fees, with an additional $10 commission fee per OSSF permit4. We could not confirm the current Collingsworth County OSSF authority; ask the County Judge's office or TCEQ before hiring an installer5,12.
Can you live in an RV or tiny home on your land in Collingsworth County?
Yes, as far as county zoning is concerned: Collingsworth County has no county zoning restriction on RV, tiny-home, or manufactured-home occupancy on unincorporated land.
Yes, as far as county zoning is concerned: Collingsworth County has no county zoning restriction on RV, tiny-home, or manufactured-home occupancy on unincorporated land6. That answer does not waive sanitation rules; constructing, installing, repairing, extending, or altering an off-grid septic system or holding tank almost always requires an OSSF permit2,13. Development in a county-administered mapped floodplain also requires a floodplain development permit3. We could not confirm a separate county rule for long-term RV utility connections or tiny-home construction, so ask the County Judge's office about the parcel and ask the identified OSSF authority about wastewater before moving onto the land5,12.

Collingsworth County gets about 24 inches of rain a year and experiences severe drought roughly 37% of years, so price a dependable water source before closing14. Only about 25% of county soils avoid severe limitations for a conventional septic drain field, making a site evaluation important even on acreage14. Check the flood map and budget for the county floodplain development permit if the site lies in a county-administered mapped floodplain3. For frontage on a state highway, a new or modified driveway needs an executed TxDOT driveway permit and advance notice before right-of-way construction; the rule does not cover every driveway on a county or local road9. The typical effective property-tax rate is about 1.3%, with a median annual bill of $1,37814. We could not confirm the private-well permit rule or current OSSF authority, so ask the County Judge's office before closing5.
Watch-outs
- Collingsworth County has no zoning ordinance, so there's no county-set minimum lot size, setback, or dwelling-size rule -- but that also means there's no county protection against what a neighbor builds next to you6.
- Confirm who issues the septic permit and what the OSSF permit and inspection fees will be before designing the system; the current Collingsworth County authority remains unconfirmed4,12.
- Development in a county-administered mapped floodplain needs a floodplain development permit even though unincorporated Collingsworth County does not require a general building permit1,3.
- The Texas owner-builder provision is only a conditional exception from a notice-related penalty for someone building or contracting their own primary residence; it is not a blanket waiver of inspections, septic, fire, or other rules11.
- Dividing unincorporated land can trigger platting even without zoning, and the agricultural-use exception is conditional on the tract's use and layout7,8.
