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

No. Unincorporated Brewster County does not require a county building permit to build a home¹. Texas fire-code permit authority is limited to qualifying counties and applies to commercial buildings, public buildings, and multifamily dwellings with at least four units, not an ordinary single-family home⁸. A county fire marshal may still inspect for fire or life-safety hazards and must inspect a structure when called on to do so; without a county fire code, the marshal may use a nationally recognized code or standard adopted by Texas⁹. State licensing exemptions let an owner perform electrical work on a dwelling the owner occupies, plumbing on the owner's homestead, and air-conditioning or refrigeration work in a solely owned home, but those exemptions do not cover every trade¹⁰. Brewster County's general building-inspection and certificate-of-occupancy procedures could not be confirmed; ask the Brewster County Courthouse before construction¹. The unincorporated-area answer does not cover land inside Alpine, where city zoning applies². Brewster County's designated representative still handles septic permits and inspections countywide¹.

A home on unincorporated Brewster County land does not require a county building permit¹. For septic permits, including inside Alpine, the Brewster County OSSF County Designated Representative handles septic permitting, inspections, and questions countywide at 432-294-3021¹. For well registration and any required drilling or production permits, contact the Brewster County Groundwater Conservation District at 432-244-6030¹. The Brewster County Courthouse is at 201 West Avenue E, Alpine, TX 79830, and its main number is (432) 837-6200¹. A utility crossing under a county road requires a $50 Road & Bridge Crossing Permit; paved roads must be bored, while trenching an unpaved road can bring added repair costs¹¹.

Brewster County has no county zoning ordinance for unincorporated land¹. Texas gives counties only narrow, place-specific zoning powers rather than general statewide zoning authority⁶. Unincorporated Brewster County has no county zoning rule for minimum dwelling size, minimum lot size, setbacks, lot coverage, building height, accessory dwellings, RV occupancy, tiny-home occupancy, manufactured-home occupancy, or temporary camping⁶. Separate septic and well requirements still apply^3,4.

Inside Alpine, use and development follow the applicable city zoning district; Alpine's ordinance regulates uses, building height and bulk, yards, and density^2,12. Septic permits and inspections remain with Brewster County's designated representative¹. Alpine's Planning and Zoning Commission advises the City Council on planning and zoning¹³. For a parcel near the city boundary, consult Alpine's official records: zoning and annexation boundaries are established by ordinance¹⁴.

Brewster County's OSSF County Designated Representative handles septic permitting, inspections, and questions throughout the county, including addresses inside cities¹. Texas requires a septic permit to construct, install, alter, extend, or repair an OSSF, subject to narrow exemptions and any stricter local requirements⁴. Before starting a permitted system, submit the application, site evaluation, required planning materials, and fee and receive an Authorization to Construct⁴. The county application lists a $240 single-family fee, subject to current confirmation⁵. The OSSF drawing must show setbacks from wells, water lines, ponds, streams, improvements, and the 100-year floodplain, along with a site-evaluation test hole and legal description¹⁵. The installer must give at least five working days' notice before inspection, and a permitted system receives authority to operate only after it passes⁵. The narrow exemption requires every listed condition, including one single-family dwelling on at least 10 acres and every system component at least 100 feet from the property line⁴. Only about 17% of Brewster County soils are rated “not limited” for a conventional drain field, so plan for a site-specific evaluation¹⁶.

The absence of county zoning on unincorporated Brewster County land does not waive wastewater requirements: an OSSF needs a septic permit unless an exemption applies, and boreholes, cesspools, and seepage pits are prohibited^4,5. A private well must be registered, and a non-exempt well needs drilling and production permits before drilling and operation³. Inside Alpine, check the proposed RV or tiny-home use against the applicable city zoning district². Brewster County's designated representative continues to handle septic permits and inspections countywide¹.

1. Confirm the parcel jurisdiction: unincorporated Brewster County has no county zoning, while Alpine sets city zoning^1,2.
2. For unincorporated land, no county building permit is required for a home¹.
3. Ask the Brewster County Courthouse whether general building inspection or occupancy paperwork applies to the project; we could not confirm those procedures¹.
4. Register every proposed well with the groundwater district and secure drilling and production permits when the well is not exempt³.
5. Submit the septic-permit application, site evaluation, planning materials, and fee to the County Designated Representative; show the required floodplain and site-feature setbacks, then wait for authorization before construction^4,15.
6. Arrange the OSSF inspection at least five working days ahead; a permitted system must pass before it can operate⁵.
7. For a new or modified driveway onto a state highway, contact the local TxDOT district office and submit Form 1058; wait for the fully executed driveway permit and give TxDOT 24-hour notice before right-of-way work^7,17.
8. If utilities must cross a county road, apply for the $50 crossing permit and budget for possible repair charges when trenching an unpaved road¹¹.

Start with water and wastewater. Brewster County averages about 13 inches of precipitation a year, experiences severe drought in roughly 25% of years, and has only about 17% of soils rated “not limited” for a conventional septic drain field¹⁶. Confirm well feasibility with the groundwater district and septic-system feasibility with the County Designated Representative¹. Check the parcel survey and flood information early because an OSSF plan must show the 100-year floodplain and setbacks from water features, utilities, wells, and improvements¹⁵. About 20% of county land is federally owned, while population density is about 2 people per square mile, so verify legal access and service distances for the parcel¹⁶. For state-highway access, obtain the TxDOT driveway permit before right-of-way work; TxDOT must approve drainage impacts before local approval and find the completed driveway satisfactory⁷. Qualifying agricultural land may receive special appraisal, but changing its use can trigger rollback tax for the previous three years¹⁸.
