Do you need a building permit in Garza County, Texas?
It depends on where your land sits.
It depends on where your land sits. Garza County requires a building permit only for construction inside a platted subdivision: a habitable structure built new or added onto for living space, a commercial or public-use structure, or another construction project covered by the county's published permit categories1. Outside a platted subdivision, unincorporated Garza County has no general building-permit requirement1. For projects within the subdivision permit program, Garza County operates under its adopted 2003 building code, and the permit must be approved before construction begins1.
Who handles permits and land-use questions in Garza County?
Garza County does not list a separate building department; the County Clerk's office handles the building-permit application, fee, and Certificate of Occupation process for subdivision construction.
Garza County does not list a separate building department; the County Clerk's office handles the building-permit application, fee, and Certificate of Occupation process for subdivision construction8. Obtain the permit packet from the County Clerk's office, submit it there or directly to the county's inspector, and pay the permit fee at the Clerk's office once the application is approved1,8. The contractor must contact the county inspector before each required inspection, and third-party inspectors cannot participate in the county process1. After the final inspection, the inspector sends the certificate request to the County Clerk, which issues the Certificate of Occupation to the property owner1. For county road right-of-way permits, start with the County Judge's office because Commissioners' Court decides applications and appeals7,9.
Does Garza County have zoning?
No. Garza County has adopted no zoning ordinance, and Texas gives counties zoning power only through narrow, geographically specific statutes that don't reach Garza County.
No. Garza County has adopted no zoning ordinance, and Texas gives counties zoning power only through narrow, geographically specific statutes that don't reach Garza County3,4. Because there's no zoning, county rules don't set a minimum home size, minimum lot size, building-height limit, or setback for your own unincorporated land, and accessory dwellings, RVs, tiny homes, manufactured homes, and temporary camping aren't restricted by county zoning4. Inside the City of Post, it's different: the city divides itself into seven zoning districts, but those apply only within city limits10.
How do septic permits work in Garza County?
Garza County is the TCEQ-authorized agent for on-site sewage facility (OSSF/septic) permits throughout the county.
Garza County is the TCEQ-authorized agent for on-site sewage facility (OSSF/septic) permits throughout the county2. A permit and approved plan are generally required to construct, install, alter, extend, or repair an OSSF, and Garza County's local program may be stricter than the state minimums5. TCEQ's regional office is the permitting authority only where no local jurisdiction has been authorized, so that state-default route does not replace Garza County's countywide program2,5. A single-family home on at least 10 acres may qualify for an exemption only after a licensed site evaluation and only if every part of the system is at least 100 feet from the property line, the system creates no nuisance or groundwater pollution, effluent stays on the property, and the home is the tract's only dwelling5. About 31% of Garza County's soils are rated free of severe limits for a conventional septic drain field, so evaluate the site before assuming a standard system will work11. We could not confirm which Garza County office handles daily OSSF intake; call the County Clerk's office to be routed to the current contact8.
Can you live in an RV or tiny home on your land in Garza County?
Yes, as a county-zoning matter.
Yes, as a county-zoning matter. Garza County does not restrict RV, tiny-home, manufactured-home, or temporary-camping occupancy through county zoning on unincorporated land4. The building-permit rule is separate: a tiny home or other habitable structure built or added onto for living space inside a platted subdivision must go through the county permit process before construction begins1. Permitted subdivision construction is subject to county inspections, and the inspector requests a Certificate of Occupation for the property owner after the final inspection1.
Building a home in Garza County: the steps, in order
Find out whether your tract sits inside a platted subdivision; that's what decides whether Garza County requires a building permit at all.
- Find out whether your tract sits inside a platted subdivision; that's what decides whether Garza County requires a building permit at all1.
- If you're in a subdivision, get the permit application packet from the County Clerk's office, submit it there or to the county's inspector, and pay the fee once it's approved, before you start construction1,8.
- Outside a subdivision, no county building permit is required to start construction1.
- Line up your septic (OSSF) permit through Garza County, which is its own TCEQ-authorized agent countywide, unless your site qualifies for the state's 10-acre exemption; the County Clerk's office is the best starting point to find the current intake process2,5,8.
- For subdivision construction, follow the county's adopted 2003 building code and contact the county inspector before each required inspection; third-party inspectors cannot participate1.
- After final inspection, the inspector requests the Certificate of Occupation from the County Clerk for issuance to the property owner1,8.
- A driveway or access road to a private ranch, farm or residence off a Garza County road does not need a county right-of-way permit or fee7. Other work in the county road right-of-way needs the county application, required plans, supporting information and fee: a commercial driveway costs $50, an underground utility crossing without a pavement cut costs $150, and an open road-cut utility crossing costs $3007.
- If your driveway connects to a state highway instead, file TxDOT Form 1058 with the local TxDOT district office and wait for a fully executed permit before construction12.

Watch-outs
- Garza County's building-permit rule applies only inside platted subdivisions; don't assume it reaches a typical unincorporated tract outside one, and don't assume the reverse either if you're buying subdivided land1.
- Garza County does not require a county permit or fee for a driveway or access road to a private ranch, farm or residence, but a commercial driveway needs a county permit; a state-highway entrance needs TxDOT approval instead7,12.
- Garza County is the TCEQ-authorized OSSF agent countywide, but we could not confirm which specific county office handles septic permits day to day; call the County Clerk's office first to be routed correctly2,8.
- Garza County has not published an owner-builder exemption; ask the County Clerk's office directly if your subdivision project qualifies for one6,8.
