Unincorporated Goliad County, Texas does not require a building permit for a home, garage, or barn, because Texas law gives counties no general permitting power and Goliad County publishes no residential building-permit program1. The county also has no zoning ordinance, so it sets no minimum home size, no setbacks, and no use restrictions on unincorporated land2. A septic permit is still required through Goliad County Environmental Services for any on-site sewage system3, and most of the county's soils carry severe limits for a conventional drain field, so plan on a site evaluation before you count on a standard system4.

Do you need a building permit in Goliad County, Texas?
Unincorporated Goliad County, Texas does not require a building permit for a house, garage, barn, or other structure1. Texas Local Government Code Chapter 233 lets counties require building permits only in narrow situations: a fire code covering commercial buildings, public buildings, and multifamily buildings of four or more units applies only to a county over 250,000 people or adjacent to one, and Goliad County's population of 7,144 people falls far short of that threshold1112. A separate state provision lets a county apply residential building-code standards to new single-family and duplex construction, but only if the commissioners court adopts a resolution doing so, and no official Goliad County page confirms that it has11. Goliad County's own website lists septic, floodplain, and subdivision rules but no residential building-permit program1.
Who is the Goliad County building department, and how do you reach them?
Goliad County has no building department because unincorporated land needs no county building permit1. Septic applications, inspections, and Authorizations to Construct go through the Goliad County Environmental Services Department, reached at (361) 645-3337 at the courthouse, 127 N. Courthouse Square, Goliad, Texas13. Applications are filed in person at the office of the Goliad County Judge, which also sits at the courthouse and prepares subdivision plats for Commissioners Court1415. Water well drilling and operating permits go through the Goliad County Groundwater Conservation District, a separate district reached at (361) 645-171616.
Does Goliad County have zoning?
Goliad County has no general zoning ordinance over unincorporated land2. Texas law grants county zoning power only for a short list of named places, such as Padre Island in Cameron or Willacy County and the Amistad Recreation Area in Val Verde County, and Goliad County is not among them, so the county cannot adopt zoning districts even if it wanted to17. Because the county has no zoning authority, it sets no minimum dwelling size, no setbacks, no lot-coverage limit, and no building-height limit anywhere in unincorporated Goliad County6. That same lack of zoning authority means Goliad County does not restrict living in an RV, a tiny home, or a manufactured home, or temporary camping, on unincorporated land6. Inside a platted subdivision, the county's own subdivision rules still apply: a lot with an individual well and septic system must be at least two acres with 150 feet of paved street frontage, and a lot on a central water system must be at least one acre with the same frontage78.
How do septic permits work in Goliad County?
Every on-site sewage facility (OSSF) in Goliad County needs a county permit before construction begins3. The Goliad County Environmental Services Officer reviews the site evaluation, application, and technical materials, and issues an Authorization to Construct once approved; the authorization is valid for one year from issuance185. The fee is $175 for a single-family residential site and $250 for a commercial site, payable only by personal check, cashier's check, or money order513. Before the installation is covered, the owner must call Environmental Services at least three business days ahead to schedule an inspection, and a Notice of Approval typically follows in about five business days; a failed inspection adds a $65 residential or $125 commercial re-inspection fee19. Only 22% of Goliad County's soil is rated free of severe limitations for a conventional septic drain field, so most building sites should plan for a site evaluation that may call for an alternative or engineered system rather than a standard trench field4. Texas also exempts some large tracts from OSSF permitting: a single-family home on 10 acres or more can skip the state permit if a licensed site evaluator confirms no nuisance or groundwater risk, every part of the system sits at least 100 feet from the property line, effluent stays on the property, and the house is the only dwelling on the tract, though Goliad County has not confirmed on its own site whether it applies this exemption locally20.
Can you live in an RV or tiny home on your land in Goliad County?
Yes: unincorporated Goliad County places no zoning restriction on living in an RV, tiny home, or manufactured home on your own land, because the county has no zoning ordinance to set that rule62. Goliad County still requires a septic permit for any wastewater system serving that RV or tiny home, filed with Goliad County Environmental Services the same way as for a house513. A domestic well serving the RV or tiny home is exempt from a Groundwater Conservation District permit as long as it produces no more than 25,000 gallons a day or uses a pump of 17 gallons per minute or less; a larger, non-exempt well needs a drilling permit followed by an operating permit9. If the land sits inside a platted subdivision rather than open acreage, the subdivision's own minimum lot size and utility rules still apply and are worth checking before adding a second living unit on the lot721.
Building a home in Goliad County: the steps, in order
- Confirm you don't need a county building permit: unincorporated Goliad County has none, so no plan review or inspection applies to the house itself1.
- If the lot is inside a recorded subdivision, check its minimum lot size, frontage, and utility rules before you buy or design721.
- Get a site and soil evaluation from a licensed site evaluator; only 22% of the county's soil carries no severe limitation for a conventional drain field, so plan the septic budget around that evaluation4.
- Apply for an OSSF permit with Goliad County Environmental Services, submitting the application, technical sheet, four copies, and the $175 residential fee135.
- Call Environmental Services at least three business days before covering the installed system so it can be inspected1913.
- If the well will use a pump larger than 1 HP and produce more than 18 gallons per minute, get a drilling permit and then an operating permit from the Goliad County Groundwater Conservation District before drilling916.
- If the driveway will connect to a U.S. or state highway, apply to the local TxDOT district office using Form 1058 before building the approach22.
- Check whether the parcel sits in a mapped floodplain: Goliad County's subdivision rules bar all development in the floodway and require structures within the floodplain to sit above the base flood elevation23.
What to check before you buy land in Goliad County
Water: subdivisions inside the Goliad County Water Supply Corporation's service territory must use that corporation for water or sewer, since the county itself is not obligated to provide either21. A domestic well is the common alternative, and it needs no district permit if it produces 25,000 gallons a day or less, while a larger-pumped well needs a drilling and operating permit from the Groundwater Conservation District916. Soils: with only 22% of the county's soil rated free of severe limitations for a conventional septic drain field, budget time and money for a site evaluation and possibly an alternative or engineered system4. Flood: Goliad County bars all development in mapped floodways and requires structures within the floodplain to sit above the base flood elevation, though the county's site does not name a floodplain administrator to confirm a parcel's status23. Access: a driveway onto a U.S. or state highway needs a TxDOT permit built to state standards, including a minimum 15-foot radius and a maximum 24-foot width for a private residential drive24. Taxes: Goliad County's effective property tax rate runs about 1%, with a median annual property tax bill of about $1,8922526. Climate and setting: the county averages 34.2 inches of rain a year with severe drought in roughly 21.5% of years, sits about 64 miles from the nearest metro area at a population density of 8.4 people per square mile, and is projected to see about 38 days a year at or above 100°F by mid-century2728293031.
Watch-outs
- Goliad County's official site does not name a floodplain administrator, so confirm any parcel's flood-zone status and permit needs directly with the County Judge's office before you build1423.
- No official Goliad County source states an owner-builder exemption from septic licensing rules, so ask Goliad County Environmental Services directly whether a landowner can self-install rather than hire a licensed installer1013.
- The two-acre and one-acre minimum lot sizes apply only to lots inside a platted Goliad County subdivision, not to raw acreage bought outside a subdivision7.
