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 another construction project covered by the county's published permit categories13. 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 begins3.
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 construction14. 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 approved1413. The contractor must contact the county inspector before each required inspection, and third-party inspectors cannot participate in the county process2. After the final inspection, the inspector sends the certificate request to the County Clerk, which issues the Certificate of Occupation to the property owner4. For county road right-of-way permits, start with the County Judge's office because Commissioners' Court decides applications and appeals1516.
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 County67. 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 zoning7. Inside the City of Post, it's different: the city divides itself into seven zoning districts, but those apply only within city limits17.
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 county5. 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 minimums8. 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 program185. 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 dwelling8. 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 work19. We could not confirm which Garza County office handles daily OSSF intake; call the County Clerk's office to be routed to the current contact14.
Can you live in an RV or tiny home on your land in Garza County?
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 land7. 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 begins3. Permitted subdivision construction is subject to county inspections, and the inspector requests a Certificate of Occupation for the property owner after the final inspection24.
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 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 construction1413.
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 process52014.
For subdivision construction, follow the county's adopted 2003 building code and contact the county inspector before each required inspection; third-party inspectors cannot participate32.
After final inspection, the inspector requests the Certificate of Occupation from the County Clerk for issuance to the property owner414.
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 fee10. 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 $300161112.
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 construction21.
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 system19. Slope: 89.2% of the county's land sits at 15% slope or less, mostly easy to build on22. Drought: the county spends about 36.2% of years in severe drought, worth weighing against well yield before you count on irrigation or livestock water23. Subdivisions: if the parcel is inside a platted subdivision, expect a county building permit, county inspections, and a Certificate of Occupation after final inspection1324. 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 mile2425. Taxes: the effective property tax rate runs about 1.7%, with a median annual bill near $1,3162627.
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 instead101121.
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 correctly514.
Garza County has not published an owner-builder exemption; ask the County Clerk's office directly if your subdivision project qualifies for one914.

County-wide zoningAbsent
Texas grants comprehensive zoning authority to municipalities (Local Government Code Ch. 211), not to counties, so unincorporated Garza County has no county zoning.
An owner performing electrical, plumbing, or air-conditioning and refrigeration work on the owner's own residence or homestead in Texas.
Electrical work is exempt from state electrician licensing when performed on a dwelling the person owns and resides in.
Plumbing is exempt from state plumbing licensing when performed by the property owner in the property owner's homestead.
Air-conditioning and refrigeration contracting is exempt from the applicable state registration requirements when performed in a building owned solely by the person as the person's home.
These exemptions do not establish a blanket exemption for every construction trade or contractor-regulated activity.
“A person who perform electrical work on a dwelling that they own and reside in is not required by the state to be licensed as electricians.”

A local governmental entity may administer the program only after an order, ordinance, or resolution is approved by TCEQ.
The authorized agent administers the program within its approved area of jurisdiction.
Local programs may adopt requirements more stringent than state minimums.
“The authorized agent is responsible for the proper implementation of Texas Health and Safety Code, Chapter 366, 30 TAC Chapter 285, including reviewing OSSF permit applications, conducting inspections, investigating complaints, and more.”

Mixed — On-site sewage facilities, including septic systems, throughout Texas
“TCEQ is not often the OSSF permitting authority. [...] The TCEQ regional office will be the permitting authority in locations where a local jurisdiction has not been authorized.”
Septic permitLimited
Construction, installation, alteration, extension, repair, or operation of an on-site sewage facility in Garza County, including unincorporated areas.
A permit and approved plan are generally required before constructing, installing, altering, extending, repairing, or operating an OSSF.
Local permitting authorities may impose requirements more stringent than state minimums.
An OSSF may be exempt under the 10-acre rule only if it complies with all other 30 TAC Chapter 285 requirements, receives a site evaluation by a TCEQ-licensed Site Evaluator or Professional Engineer, serves a single-family dwelling on a tract of at least 10 acres, is not required to have a permit from the local permitting authority, is not causing a nuisance or polluting groundwater, all parts are at least 100 feet from the property line, effluent is disposed of on the property, and the single-family dwelling is the only dwelling on the tract.
Grandfathered systems may be exempt if installed before a local program was authorized or before September 1, 1989, whichever is earlier, are not creating a nuisance, are not in need of repair, and have had no significant increase in use or other alteration.
Emergency repairs are exempt from permitting but must be reported in writing to the permitting authority within 72 hours after repairs begin.
Applications and planning materials must be submitted to the applicable permitting authority; where no local jurisdiction is authorized, the TCEQ regional office is the permitting authority.
The permitting authority must approve or deny the planning materials and permit application within 30 days of receipt.
minimum tract size for 10-acre exemption: >= 10 acres (Single-family dwelling and all other listed conditions must be satisfied.) · minimum OSSF setback for 10-acre exemption: >= 100 feet from property line (All parts of the OSSF must satisfy the setback.) · emergency-repair reporting deadline: <= 72 hours (Measured after repairs have begun.) · permit application decision deadline: <= 30 days (Measured from receipt by the permitting authority.)

Chapter 231 does not grant a general statewide county zoning power; authority is provided through geographically or subject-matter limited subchapters.
For Padre Island, the authority applies in Cameron or Willacy County outside a municipality and within two miles of a publicly owned park or recreational development, or within two miles of a beach, wharf, or bathhouse used by at least 500 persons annually.
Other Chapter 231 subchapters address special areas including the Amistad Recreation Area in Val Verde County, military zones, certain lakes, the El Paso Mission Trail Historical Area, Lake Somerville, and Falcon Lake in Zapata County.
The cited statute was enacted effective September 1, 1987; the Falcon Lake subchapter was added effective June 15, 2007, and amended effective September 1, 2009.
Padre Island distance from publicly owned park or recreational development: <= 2 miles (Area must be outside a municipality and in Cameron or Willacy County.) · Padre Island distance from beach, wharf, or bathhouse: <= 2 miles (The beach, wharf, or bathhouse must be used by at least 500 persons annually.)

Limited — County zoning authority over unincorporated land in Texas, where a specific statutory grant applies.
“As you suggest, a county has very limited and specific zoning authority, and none that may be used to regulate construction or operation of the proposed facility.”
county building authorityLimited
Texas counties adopting and enforcing fire-code building permits for specified buildings in unincorporated areas and applying residential building-code standards in certain counties.
Under Section 233.061, the county must have a population over 250,000 or be adjacent to a county with a population over 250,000.
Under Section 233.062, the fire code applies only to commercial establishments, public buildings, and multifamily residential dwellings consisting of four or more units constructed in an unincorporated area.
The fire code does not apply to an industrial facility having a fire brigade that conforms to Occupational Health and Safety Administration requirements.
A covered applicant must submit a plan and a commissioners-court-set application fee; the county must issue or deny the permit within 30 days, and failure to act within 30 days approves the construction for purposes of the subchapter.
The fire code must conform to the International Fire Code or Uniform Fire Code as those codes existed on May 1, 2005, or establish protective measures exceeding those standards; later editions may be adopted.
Residential standards under Section 233.152 apply only if the county adopts a resolution or order and the county is within 50 miles of an international border or has a population over 100.
Those residential standards apply only to new single-family-house or duplex construction beginning after September 1, 2009; manufactured or modular structures governed by Occupations Code Chapters 1201 or 1202 are excluded from the definition of new residential construction.
A municipality's building code controls in its extraterritorial jurisdiction, and Section 233.152 does not authorize county prior approval of new residential construction or county zoning regulations.
Fire-code inspection and permit fees may be charged under a fee schedule based on building type, limited to amounts necessary to administer and enforce the subchapter; inspection fees must be reasonable and reflect approximate inspection costs.
county population threshold for fire-code authority: > 250000 persons (A county adjacent to a county over 250,000 also qualifies.) · multifamily residential dwelling threshold: >= 4 units (The fire code applies only to covered buildings constructed in an unincorporated area.) · residential-code border distance: <= 50 miles (Alternative qualification is county population over 100.) · application decision period: 30 days (If the commissioners court does not issue or deny the permit within 30 days after receiving the application and fee, construction is approved for purposes of the subchapter.) · residential standards effective construction date: > 2009-09-01 (Applies only to new residential construction that begins after September 1, 2009.)
“The commissioners court of a county with a population of over 250,000 or a county adjacent to a county with a population of over 250,000 may adopt a fire code and rules necessary to administer and enforce the fire code. [...] The fire code applies only to the following buildings constructed in an unincorporated area of the county: (1) a commercial establishment; (2) a public building; and (3) a multifamily residential dwelling consisting of four or more units.”
