Unincorporated Nolan County has no county zoning ordinance1. Nolan County therefore sets no county-zoning minimum dwelling size, minimum lot size, setback, lot-coverage or building-height rule, and no county-zoning restriction on RV, tiny-home, manufactured-home or accessory-dwelling occupancy on unincorporated land11. Inside Sweetwater, Planning and Development Services reviews zoning and subdivision requests and issues certificates of zoning compliance2. Sweetwater rezoning requires a staff meeting before submittal, a written city application and a non-refundable $300 fee, followed by Planning and Zoning Commission and City Council public hearings12. City zoning does not replace the separate TCEQ or authorized-agent septic process or Wes-Tex well requirements3,4.
How do septic permits work in Nolan County?
A septic permit and approved plan are generally required before constructing, altering, repairing, extending or operating an onsite sewage facility in Nolan County.
A septic permit and approved plan are generally required before constructing, altering, repairing, extending or operating an onsite sewage facility in Nolan County3. Submit the application and planning materials to the applicable OSSF authority; TCEQ serves where no local program is authorized, but we could not confirm Nolan County’s agent3. For a permitted system, the installer must give at least 5 working days’ notice before the construction inspection; a failed system cannot be used until it passes5. The 10-acre exception requires the only dwelling on the tract to be a single-family home, a licensed site evaluation, all system parts at least 100 feet from property lines, onsite effluent disposal, no nuisance or groundwater pollution, and compliance with state planning and installation standards3. About 11.3% of Nolan County soils have no severe limits for conventional drain fields, making site evaluation an early homesite decision6.
