Montague County, TX Building Permits, Zoning & Septic Rules

Unincorporated Montague County, Texas has no general building-permit program and no zoning ordinance, because Texas gives counties zoning power only over a handful of named areas that don't include Montague County¹²³. Septic is different: Montague County itself, not the state, permits on-site sewage facilities (OSSFs) through its own Sewage Inspector⁴⁵. Any development in a mapped floodplain still needs a county Floodplain Development Permit, and land divided into new lots falls under subdivision regulations the county adopted in 2024⁶⁷.

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

No. Unincorporated Montague County has no general residential building-permit program, and Texas counties are not given broad authority to require one¹. State law grants that power only in narrow situations, such as fire-code permits for counties over 250,000 people or adjacent to one, covering commercial buildings and multifamily dwellings of four or more units, or residential standards a county formally adopts by resolution near an international border¹³. Montague County, with about 21,598 residents, doesn't meet the population trigger, and no adoption of the border-area residential standards was found for the county¹³¹⁴. So an ordinary single-family home, cabin, barn or shop built in unincorporated Montague County doesn't go through a county building-permit review, though the county does regulate the septic system serving it¹⁵.

Who handles permits in Montague County, and how do you reach them?

There's no county building or zoning office to call for an ordinary home, because Montague County doesn't run a general building-permit program¹. Septic (OSSF) permits are different: they go through the county's own Sewage Inspector, who acts as TCEQ's authorized agent for Montague County⁵¹⁵. For floodplain development, subdivision questions, county-road access and anything else the county does regulate, the Montague County Judge's office at the courthouse in Montague is the general contact; no separate floodplain-administrator or planning office is listed on the county's own site¹⁶. If your driveway will connect to a state highway rather than a county road, that permit goes through TxDOT instead, using Form 1058¹⁷.

Does Montague County have zoning?

No. Montague County has no zoning ordinance, and Texas law gives counties zoning authority only for a handful of specific areas, such as Padre Island beaches in Cameron or Willacy County and a few named lakes and military zones, none of which include Montague County²³. That means the county itself sets no minimum home size, no setbacks, no building-height limit and no zoning districts¹⁰. It also means RVs, tiny homes, manufactured homes and temporary camping on your own unincorporated lot are unrestricted under county rules¹⁰. The one zoning that does exist nearby is inside the City of Bowie and its extraterritorial jurisdiction, where the Planning and Zoning Commission reviews rezoning, platting and subdivision requests; that zoning reaches only Bowie and its ETJ, not the rest of unincorporated Montague County¹².

How do septic permits work in Montague County?

Montague County itself, not the state, permits on-site sewage facilities (OSSFs): the county's Sewage Inspector reviews applications against county standards as TCEQ's authorized local agent¹⁵⁵. No OSSF construction may start without the proper paperwork, and no physical parts of a system may be installed until the county confirms approval⁸. The county sets a minimum lot size for a system serving a single-family residence: 1 acre with public water, or 2 acres with a private well⁹. A conventional system permit costs $410, and an aerobic system permit costs $510; aerobic systems also need a signed maintenance-provider service contract and a notarized affidavit filed with the County Clerk⁸. After installation, the system must be inspected before coverup, and any change to the structure, system components or ownership may require a new permit¹⁸. Only 14.7% of Montague County's soils are rated free of severe limits for a conventional drain field, so budget for a site and soil evaluation early¹⁹.

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

Yes, as far as county rules go. Unincorporated Montague County has no zoning ordinance restricting how you occupy your own land, so there's no county rule limiting RV, tiny-home or temporary-camping use, and no minimum home size to meet¹⁰. A separate county rule only reaches Manufactured Home Rental Communities: land split into two or more spaces rented or leased for under 60 months without a purchase option for manufactured homes, which requires minimum infrastructure under a county order, but that rule doesn't apply to a single manufactured home on your own lot¹¹. Whatever you live in, remember it still needs a compliant OSSF permit if it has plumbing, with the same 1-or-2-acre minimum lot size that applies to any single-family residence⁸⁹.

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

First, confirm your lot meets the county's OSSF minimum: 1 acre with public water or 2 acres with a private well per single-family residence⁹. Second, order a site and soil evaluation for your septic system early, since only 14.7% of the county's soils are free of severe limitations for a conventional drain field¹⁹. Third, apply for your OSSF permit through the Montague County Sewage Inspector before any construction, and do not install any physical system parts until the county confirms approval⁵⁸. Fourth, if your property is in a mapped Special Flood Hazard Area, get a Floodplain Development Permit before you start work, which may require an Elevation Certificate⁶. Fifth, if you're creating a new lot rather than buying an existing one, check the county's subdivision regulations, adopted May 28, 2024, for survey, road-access and utility requirements⁷. Sixth, if your driveway will connect to a state highway, submit TxDOT Form 1058 and give 24-hour notice before construction begins¹⁷. Finally, build: there is no countywide building-permit review for an ordinary single-family home outside a floodplain¹.

What to check before you buy land in Montague County

Septic soils deserve early attention: only 14.7% of Montague County's land is free of severe limitations for a conventional drain field, and the county's own 1-or-2-acre minimum lot size for an OSSF can rule out very small parcels¹⁹⁹. Water matters too: annual precipitation runs about 35.7 inches a year, with severe drought in 23.8% of years²⁰²¹. Land here is flat and open for building, with 99.7% of the county at 15% slope or less and only 28.9% forested²²²³. Check FEMA flood maps before you buy: any development in a mapped Special Flood Hazard Area needs a county Floodplain Development Permit⁶. If the tract was recently split off a larger parcel, confirm it complied with the county's subdivision regulations, adopted May 28, 2024⁷. If you want to be inside a town, remember Bowie and its ETJ have their own zoning that this guide's county-level rules don't cover¹². Property tax runs about 1.0% effectively, with a median bill near $1,802 a year, against a typical home value around $256,517²⁴²⁵²⁶.

Watch-outs

Montague County has no general building-permit program, but it does run its own septic (OSSF) permitting through the Sewage Inspector, unlike counties where the state (TCEQ) permits septic directly; don't assume 'no building permit' means 'no septic permit'⁵¹⁵.
Any development in a mapped floodplain needs a county Floodplain Development Permit even though the county has no general zoning or building code; check FEMA maps before you build⁶.
Bowie and its extraterritorial jurisdiction have their own zoning; the 'no zoning' rules in this guide apply only to unincorporated land outside Bowie's ETJ¹².
