Do you need a building permit in Andrews County, Texas?
Unincorporated Andrews County does not require a general building permit for an ordinary home, and no county building-permit or inspection department was identified.
Unincorporated Andrews County does not require a general building permit for an ordinary home, and no county building-permit or inspection department was identified1. This answer does not establish the building-permit requirements inside the City of Andrews; confirm those with the city before building there1. We could not confirm an Andrews County building code, building inspection, or certificate-of-occupancy rule1. State code editions apply to industrialized housing, buildings, modules, and modular components rather than every conventional building statewide8. A Texas owner-builder provision is narrower still: if the relevant county residential-code subchapter applies, a person building or acting as contractor for a planned primary residence may avoid only a specified inspection-notice penalty6. No Andrews County adoption of that subchapter or broader owner-builder exemption was confirmed6.
Who issues building permits in Andrews County?
Andrews County has no listed general building-permit department for unincorporated home construction.
Andrews County has no listed general building-permit department for unincorporated home construction1. The building-permit requirement inside the City of Andrews was not confirmed, so contact the city for a parcel within city limits1. Zoning is separate: the City of Andrews applies zoning within its incorporated limits2,3. Septic authority does not move to the city; the Andrews County Health Department administers on-site sewage facility permits and inspections countywide4. Its OSSF office is at 208 NW 2nd Street, Andrews, TX 79714, and its phone number is 432-524-14349. A separate county process applies when land is divided: preliminary plats, final plats, and amended plats or replats are submitted with the applicable fees for county review7.
Does Andrews County have zoning?
We could not confirm whether Andrews County has adopted zoning for unincorporated land; the available county finding says no, but no official Andrews County statement or ordinance verified that conclusion.
We could not confirm whether Andrews County has adopted zoning for unincorporated land; the available county finding says no, but no official Andrews County statement or ordinance verified that conclusion10. The incorporated City of Andrews does have a zoning ordinance, and city materials also show zoning action tied to annexed land2,3. For land inside Andrews, ask the city about the zoning district, setbacks, minimum dwelling or lot size, RV use, tiny homes, manufactured homes, and accessory dwellings before purchase2. For unincorporated land, ask the county to confirm any parcel-specific land-use limits rather than assuming the land is unrestricted10. City zoning does not replace Andrews County subdivision review or the countywide septic-permit process4,7.
How do septic permits work in Andrews County?
The Andrews County Health Department and its OSSF officer administer septic plan review, permitting, and installation inspections.
The Andrews County Health Department and its OSSF officer administer septic plan review, permitting, and installation inspections4. Start with a 911 addressing receipt, a completed application, a licensed site evaluation, and the permit fee; installation cannot begin until Health Department approval arrives4. The OSSF fee schedule lists $250 for a residential permit, $500 for a commercial permit, $150 for reinspection, and $25 for research and copies; fees are paid at the Health Department, not to the inspector in the field4. A commercial installation requires professional design and a licensed professional installer4. Leave the completed system uncovered and give the inspector at least 24 hours' notice4. A permit application remains valid for 12 months, after which an unfinished system requires a new fee4. Texas has a narrow exemption for a single home on at least 10 acres only when every condition is met, including a licensed site evaluation, all system parts at least 100 feet from property lines, and disposal remaining on the tract5.
Can you live in an RV or tiny home in Andrews County?
We could not confirm county rules for RV living, tiny-home occupancy, manufactured homes, accessory dwellings, or temporary camping in unincorporated Andrews County.
We could not confirm county rules for RV living, tiny-home occupancy, manufactured homes, accessory dwellings, or temporary camping in unincorporated Andrews County10. Inside the incorporated City of Andrews, city zoning applies, so ask the city whether the parcel's zoning district allows the proposed dwelling or occupancy2,3. Septic remains a countywide matter: constructing, installing, altering, extending, or repairing an on-site sewage facility requires approval unless every condition of a Texas exemption is satisfied4,5. Andrews County's septic application includes a single RV among the listed property uses, but the form establishes the septic process rather than permission to live in an RV4. Utility connections, off-grid sanitation alternatives, and occupancy approval also remain unconfirmed, so take the proposed dwelling and wastewater plan to the Health Department before committing to the setup1,4.
How do you build a home in Andrews County, step by step?
Confirm whether the parcel is inside the City of Andrews; city zoning applies inside its limits, while the county building-permit finding applies to unincorporated land.
- Confirm whether the parcel is inside the City of Andrews; city zoning applies inside its limits, while the county building-permit finding applies to unincorporated land1,2.
- Determine whether a subdivision plat or replat is involved; Andrews County reviews preliminary, final, and amended plats or replats7.
- Secure the 911 address receipt and hire a licensed site evaluator for the septic site evaluation4.
- Submit the OSSF application and fee to the Andrews County Health Department, then wait for authorization before septic installation begins4.
- Leave the installed septic system uncovered, post the 911 address signage, and arrange the county inspection with at least 24 hours' notice4.
What should you check before buying land in Andrews County?
Check wastewater feasibility first: 88.9% of Andrews County soils are rated without severe limitations for a conventional drain field, but the county still requires a licensed site evaluation and approval for a permitted system.
Check wastewater feasibility first: 88.9% of Andrews County soils are rated without severe limitations for a conventional drain field, but the county still requires a licensed site evaluation and approval for a permitted system4,12. Verify water carefully because annual precipitation averages 14.3 inches and severe drought occurs in 34.4% of years12. Confirm legal access and identify whether the road is a state highway, because a new or modified state-highway driveway requires TxDOT approval13. If the tract will be divided, budget for county plat review; a final plat has a $500 base fee plus $10 per lot, while a preliminary plat in a floodplain has a $1,000 base fee plus $10 per lot7. For subdivision plats touching a floodplain, the checklist can require mapped flood information, elevations, and an engineering study under the stated conditions14. We could not confirm a general floodplain construction permit outside subdivision review, so ask the County Judge's Office before building in a mapped hazard area7.
Watch-outs
- Andrews County has not confirmed a general certificate-of-occupancy or building-inspection process, so ask the County Judge's Office about any project-specific sign-off before construction1.
- A subdivision plat involving a floodplain can require flood-zone information, minimum floor elevations, and engineering analysis, but the reviewed material does not establish a general non-subdivision floodplain permit14.
- An OSSF installation must remain uncovered for inspection, and the owner or installer must give at least 24 hours' notice4.
