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

Unincorporated Goliad County, Texas does not require prior county approval before qualifying new residential construction begins¹. That rule does not remove septic, subdivision, floodplain, or municipal requirements¹. Texas law can require privately arranged code inspections when a qualifying county adopts the residential-construction framework, but we could not confirm that Goliad County has adopted it; ask the County Judge's office before construction^2,10. Inside the City of Goliad, contractors are expected to follow the city's adopted International Building Codes⁵.

Goliad County does not require prior county approval before qualifying unincorporated residential construction begins¹. Ask the County Judge's office whether the state residential-inspection framework applies to the project, because the available rule requires inspections only after county adoption and we could not confirm adoption^2,10. Septic applications, inspections, and Authorizations to Construct go through the Goliad County Environmental Services Department at the courthouse¹¹. Water-well drilling and operating permits for non-exempt wells go through the Goliad County Groundwater Conservation District⁹.

Unincorporated Goliad County has no county zoning districts, minimum dwelling size, zoning setbacks, lot-coverage limit, or building-height limit⁶. Inside the City of Goliad, the municipal zoning ordinance divides land into districts shown on the official zoning map, so city rules must be checked separately⁴. County subdivision rules still govern qualifying plats outside municipal jurisdiction, and city approval comes before county approval for a plat in a city's extraterritorial jurisdiction⁴. In an unincorporated subdivision, a lot with an individual well and septic system must be at least two acres with 150 feet of paved street frontage, while a lot on central water must be at least one acre with the same frontage⁸.

Goliad County is the state-authorized agent for on-site sewage facilities and administers septic permits and inspections countywide³. Apply in the property owner's name with the technical sheet, planning materials, site and soil evaluation, directions, fee, and required copies; proprietary and non-standard systems need a professional design¹¹. The Environmental Services Officer issues an Authorization to Construct after approval, and the authorization remains valid for one year¹¹. The installation must be inspected before covering, with Environmental Services contacted at least three business days in advance^11,12. County materials conflict on current septic and reinspection fees, so confirm the amount with Environmental Services before submitting payment^11,12. Only 22% of Goliad County soil is rated free of severe limits for a conventional drain field, so arrange the site evaluation before assuming a standard system will work¹³.

Unincorporated Goliad County does not use county zoning to restrict RV, tiny-home, manufactured-home, or temporary-camping occupancy⁶. That answer changes inside the City of Goliad, where municipal zoning districts include specific provisions for manufactured homes, recreational-vehicle parks, and tiny homes⁴. Goliad County still requires a septic permit for an on-site sewage system serving an RV or tiny home^7,11. A domestic well can be exempt if it meets the district's use, pump, production, and siting conditions; a non-exempt well needs drilling and operating permits⁹. Subdivision rules and private restrictions can add separate limits, so check the recorded plat and deed before relying on the county zoning answer⁸.

1. Identify the jurisdiction: City of Goliad zoning and building codes apply inside the city, while unincorporated residential construction does not need prior county approval^1,4,5.
2. Ask the County Judge's office whether the state residential-inspection framework applies before scheduling construction^2,10.
3. Check subdivision lot size, frontage, utility, and driveway rules before design^8,14.
4. Obtain the septic site and soil evaluation, then submit the OSSF application package to Goliad County Environmental Services¹¹.
5. Contact Environmental Services at least three business days before the septic installation is covered^11,12.
6. Confirm well exemption status with the Groundwater Conservation District; non-exempt wells need drilling and operating permits⁹.
7. Obtain highway authorization where a subdivision lot fronts a U.S. or state highway¹⁴.
8. For a subdivision plat, document floodplain compliance; floodplain or drainage-easement development is case-specific and floodway development is barred¹⁴.

Water: subdivisions in the Goliad County Water Supply Corporation's service territory must use that corporation for water or sewer¹⁴. A well may be exempt only when it meets the Groundwater Conservation District's use, capacity, and siting conditions; non-exempt wells require drilling and operating permits⁹. Soils: only 22% of county soil is rated free of severe limitations for a conventional drain field, so budget for a site evaluation and possibly a different system design¹³. Flood: subdivision development in a floodplain or drainage easement is reviewed case by case, and no development is permitted in the floodway¹⁴. Access: subdivision lots fronting a U.S. or state highway need authorization from the appropriate highway official¹⁴. Jurisdiction: confirm whether the parcel is inside the City of Goliad, where municipal zoning and building codes apply^4,5.
