Garza County, Texas requires a building permit only for construction inside a platted subdivision; land outside a subdivision in unincorporated Garza County needs no county building permit at all1. The county has no zoning ordinance either way, so RVs, tiny homes, and manufactured homes on your own land aren't restricted by county zoning23. Garza County handles septic permitting countywide, and a permit and approved plan are generally required for septic work45.

Do you need a building permit in Garza County, Texas?

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 any other construction project not covered by the International Residential Code or Commercial Construction Provision, including work within a county road right-of-way9. Outside a platted subdivision, unincorporated Garza County has no general building-permit requirement at all1. Garza County operates under the 2003 building code, as approved by Commissioners' Court on May 8, 20069.

Who handles permits and land-use questions in Garza County?

There's no separate building department: the County Clerk's office handles the building-permit application, fee, and certificate-of-occupancy process for subdivision construction10. You 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 it's approved109. For anything needing Commissioners' Court action, including a county road right-of-way permit, start with the County Judge's office11.

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 County23. 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 zoning3. Inside the City of Post, it's different: the city divides itself into seven zoning districts, but those apply only within city limits12.

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 county4. 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 program134. 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 work14. We could not confirm which Garza County office handles daily OSSF intake; call the County Clerk's office to be routed to the current contact10.

Can you live in an RV or tiny home on your land in Garza County?

Yes. Garza County has no zoning ordinance, so RVs, tiny homes, and manufactured homes on your own unincorporated land aren't restricted by county zoning3. That's separate from the building-permit rule: if your RV, tiny home, or manufactured home sits inside a platted subdivision and counts as a habitable structure used for living space, it still needs a subdivision building permit and, eventually, a certificate of occupancy96.

Building a home in Garza County: the steps, in order

  1. Find out whether your tract sits inside a platted subdivision; that's what decides whether Garza County requires a building permit at all1.
  2. 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 construction109.
  3. Outside a subdivision, no county building permit is required to start construction1.
  4. 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 process41510.
  5. If you're building in a subdivision, contact the county's inspector before each inspection; third-party inspectors aren't allowed to take part in Garza County's process16.
  6. After final inspection, the inspector requests your certificate of occupation from the County Clerk610.
  7. If any of your work touches a Garza County road right-of-way, get a county permit first: it covers construction plans, erosion- and fire-protection methods, and a barricade and lighting plan, and Commissioners' Court can reject unsafe or inaccurate applications8.
  8. 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 construction17.

What to check before you buy land in Garza County

Soils: about 31% of Garza County's soils are rated free of severe limits for a conventional septic drain field, on the lower side, so budget for a site evaluation and possibly an engineered system14. Slope: 89.2% of the county's land sits at 15% slope or less, mostly easy to build on18. Drought: the county spends about 36.2% of years in severe drought, worth weighing against well yield before you count on irrigation or livestock water19. Subdivisions: if the parcel you're considering is inside a platted subdivision, expect a Garza County building-permit and certificate-of-occupancy process that a similar unincorporated tract outside one wouldn't need9. Location: the nearest city of 100,000 or more is about 43 miles from Garza County's center, and the county has about 5.1 people per square mile2021. Taxes: the effective property tax rate runs about 1.7%, with a median annual bill near $1,3162223.

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 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 correctly410.
  • Garza County has not published an owner-builder exemption; ask the County Clerk's office directly if your subdivision project qualifies for one710.
