Building permits, zoning and septic rules in Martin County, Texas
36Index Score / 100 #242 of 254 in Texas
Unincorporated Martin County, Texas appears not to require a general county building permit and has adopted no county zoning ordinance for rural land12; the City of Stanton zones inside its limits3. Inside Stanton, construction must meet the city's adopted 2006 International Building Code, and a certificate of occupancy is required before moving in45. Septic permits for the whole county come from Martin County OSSF, not the city, and county-road driveway permits still apply67.

Do you need a building permit in Martin County, Texas?
Unincorporated Martin County appears not to require a general residential building permit; the available county information describes no county building-permit program1. Inside Stanton, all construction must meet the city's adopted 2006 International Building Code, and a certificate of occupancy is required before moving in45. Those city rules are not evidence of a county rule for unincorporated land4. Before relying on the rural answer for a particular tract, give the Martin County Judge's office the parcel location and ask whether any county approval applies8. Texas separately regulates covered industrialized housing and modules, but that program is not a general county inspection of every site-built rural home14.
Who issues building permits and septic permits in Martin County?
Martin County does not list a dedicated building or zoning department, so the County Judge's office is the practical first call for parcel-specific questions on unincorporated land8. Inside Stanton, the city sets building-code, occupancy and zoning rules, while septic permits stay with Martin County OSSF45. Septic applications go to Martin County OSSF15. County-road access applications go to Commissioners' Court or the County Judge, while Martin County Road & Bridge handles county-road and right-of-way questions7816. The access permit has no fee, though the permit holder remains responsible for costs required under the policy11.
Does Martin County have zoning?
Martin County has adopted no county zoning ordinance for unincorporated land29. The City of Stanton is different: its code divides the city into seven zoning districts, and changes go through the city's Planning and Zoning Commission317. For unincorporated land, Martin County therefore sets no zoning-based minimum dwelling size, minimum lot size, setback, building-height limit, or lot-coverage rule; county zoning also does not restrict accessory dwellings, RV occupancy, tiny-home occupancy, manufactured-home occupancy, or temporary camping9. That answer is limited to county zoning: deed restrictions, city jurisdiction, wastewater rules, road access, and floodplain requirements are separate. Agricultural or open-space appraisal is not a blanket exemption from every county rule; the relevant statutory protection concerns a narrow county-power provision with conditions that do not describe a general Martin County permit exemption18.
How do septic and well permits work in Martin County?
Martin County is the permitting authority for on-site sewage facilities, including new and modified residential, commercial, mobile-home, multifamily, and RV-park systems1920. Submit the application, technical sheet, site evaluation, installer drawing, planning materials, directions, and fee; proprietary and non-standard systems require professional design6. A new residential permit costs $200, fees are non-refundable, and each re-inspection costs half the permit amount10. Wait for the Authorization to Construct before starting; it remains valid for one year21. Martin County requires an installation inspection before the system is covered; contact the office at least 24 hours ahead, and expect a Notice of Approval after a successful inspection22. A qualifying single-family tract of at least 10 acres may use the state permit exemption only when all stated siting and use conditions are met23. Private wells inside the Permian Basin Underground Water Conservation District need a registration for an exempt well rather than a drilling permit, at $200 per application under the District's 2025 rules; confirm whether your tract lies in the District13. About 75.1% of county soils lack severe conventional drain-field limitations, but each site still needs evaluation2421.
Can you live in an RV or tiny home on your land in Martin County?
Martin County zoning does not restrict RV, tiny-home, manufactured-home, or temporary-camping occupancy on your own unincorporated land9. That is not permission to dispose of wastewater without approval. An off-grid OSSF still requires a county permit and Authorization to Construct, site evaluation and planning materials, disclosure of wells and required separation distances, and inspection before the system is covered25. The county material does not confirm that every alternative sanitation method is allowed, so ask Martin County OSSF about any composting toilet, holding tank, graywater plan, or other setup that is not the permitted OSSF described in its application2515.
How do you build a home in Martin County, step by step?
Establish whether the tract is inside Stanton; city construction must meet the 2006 International Building Code and receive a certificate of occupancy before move-in45.
For unincorporated land, ask the County Judge's office whether any parcel-specific county approval applies18.
Plan wastewater with Martin County OSSF; submit the required application materials and site evaluation, and budget $200 for a new residential permit15610.
Wait for the Authorization to Construct before septic work begins21.
Arrange the septic inspection at least 24 hours in advance and leave the system uncovered until it passes22.
For a county-road driveway, obtain the no-fee access permit through Commissioners' Court or the County Judge, then give 48 hours' notice before work7118.
For state-highway access, file TxDOT Form 1058 and wait for the executed permit before construction12.
What should you check before buying land in Martin County?
Soils: about 75.1% of Martin County soils lack severe limitations for a conventional septic drain field, but the county still requires a site evaluation2421. Terrain: 100% of county land is at a slope of 15% or less26. Water: severe drought occurs in about 36.7% of years, so verify well yield and water availability rather than assuming a rural tract can support irrigation or livestock27. Access: a county-road driveway needs a no-fee county permit, while state-highway access uses TxDOT Form 105871112. Location: the nearest city of 100,000 or more is about 22 miles from the county center, and county density is about 5.7 people per square mile2829. Taxes: the effective rate is about 0.9%, with a median annual bill near $1,4343031.
Watch-outs
We could not confirm a Martin County owner-builder exemption; ask the County Judge's office whether any parcel-specific approval changes that answer328.
The Martin County OSSF program shares its mailing address with the County Judge's office, so if you can't reach septic staff directly, the County Judge's office can point you the right way8.
Off-grid living does not waive wastewater review, and the county material does not establish that every alternative sanitation method is allowed25.

Industrialized housing or buildings installed in Texas, including purchasers or lessees acquiring a unit for their own or their company’s use.
A person purchasing or leasing an industrialized house or building for their own use or their company’s use may file for an installation permit instead of registering as an industrialized builder.
A person responsible for assembly, connection, and on-site construction for persons other than themselves must be registered as an industrialized builder.
Municipalities may require applicable local permits and licenses before construction begins when the municipality regulates the installation.
“A person who is a retailer of industrialized housing or buildings, or who is responsible for the assembly, connection, and on-site construction and erection of an industrialized house or building for persons other than themselves, must be registered as an industrialized builder. Subcontractors do not require the registration unless required by other applicable state laws. For example, electricians, HVAC contractors, and plumbers must be licensed in accordance with the applicable state law. If you are purchasing or leasing an industrialized house or building for your own use, or your company's use, you may file for an installation permit in lieu of registering as an industrialized builder.”
Owner-builder exemptionConditional
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.

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.

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.”

Living off-grid in Martin County, Texas
Is Martin County a good place to live off-grid or homestead?
Martin County scores 36/100 on the Bolthole Index, a marginal county profile. Its strengths: low administrative friction for a quiet rural property and manageable long-term carry cost. Watch-outs: thin water margin (15.8″/yr rainfall) and elevated mid-century heat, water, rain, or wildfire exposure.
Do you need a building permit in Martin County, Texas?
Martin County does not require a county building permit for a home in unincorporated areas, and it has no county-wide zoning. Onsite septic is permitted by Martin County OSSF Program (TCEQ authorized agent, Designated Representative). Owner-builders may act as their own contractor to build their home. These answers are quoted from official sources and independently re-checked. Rules change and cities within the county differ — always confirm with the county before you buy or build.
Can you live in an RV or tiny home on your land in Martin County?
Living in an RV on your own land in Martin County is allowed: Unincorporated Martin County: no county rule sets this, because Martin County has adopted no county zoning ordinance (Texas law lets some counties zone, but this one has not). The county legal census found no county zoning ordinance, citing guides.sll.texas.gov. Septic, floodplain, subdivision and health rules still apply; cities and towns set their own rules inside their limits. Chapter 231 does not grant a general statewide county zoning power; authority is provided through geographically or subject-matter limited subchapters. A tiny home is allowed.
