Building permits, zoning and land rules in Maverick County, Texas

#149 of 254 in Texas

Unincorporated Maverick County, Texas does not require a general building permit for a house, barn or shed. Texas only gives counties narrow, population-gated power over building permits, and Maverick County's population of about 57,762 falls well short of the threshold that would trigger it¹²³. Septic is different: Maverick County itself is the state-authorized agent that permits on-site sewage systems in the unincorporated county, so most septic installs still need a permit unless the tract qualifies for Texas's 10-acre exemption⁴⁵. There is no county zoning ordinance either, so call the Planning Department directly about your parcel⁶⁷.

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

Unincorporated Maverick County does not enforce a general building code, so a typical single-family home, barn or shed does not need a county building permit³. Texas only lets a county require building permits in two narrow situations: a fire code for commercial buildings, public buildings and residential buildings of four or more units, available only to counties over 250,000 people or adjacent to one; and residential construction standards that a county must adopt by its own resolution or order before they take effect². Maverick County's population is about 57,762, well under the fire-code threshold¹. Maverick sits directly on the border with Mexico, which would satisfy the residential-standards distance test, but no resolution or order adopting those standards was found on the county's website, so they do not appear to be in force²³. The county's own site lists a Building Inspector and a Code Enforcement office¹¹¹²; call the Building Inspector's office first if your project is commercial, multifamily, or otherwise unusual, since it is best placed to say whether anything applies to it.

Who is the Maverick County building department, and how do you reach them?

Three Maverick County offices handle construction-related questions, and all three sit at the same downtown Eagle Pass address, 500 Quarry St., Eagle Pass, TX 78852¹¹¹²⁷. The Building Inspector's office is reached at 830-773-4377 or [email protected]¹¹. Code Enforcement, which handles nuisance and code-compliance complaints in the unincorporated county, is reached at 830-773-4669 or [email protected]¹². The Planning Department is reached at 830-773-4377 or [email protected]⁷. Call any of the three during normal weekday business hours before starting a project, since none of them publishes a fee schedule or an online permit application.

Does Maverick County have zoning?

Unincorporated Maverick County has no county zoning ordinance⁶. Texas gives counties zoning power only in a short list of specific places named by statute, such as Padre Island in Cameron or Willacy County, the Amistad Recreation Area in Val Verde County, certain military zones, the El Paso Mission Trail Historical Area, Lake Somerville, and Falcon Lake in Zapata County, and Maverick County is not one of them⁸. That means there is no county-level ordinance setting minimum lot sizes, use districts, or setbacks on unincorporated land here. Maverick County does list a Planning Department⁷, but its role is not published beyond a name and contact point on the county's site; call it directly at 830-773-4377 or [email protected] to ask about any subdivision platting rules before you buy⁷. None of this affects land inside Eagle Pass city limits, which sets its own zoning and permit rules separate from the county.

How do septic permits work in Maverick County?

Maverick County is itself the state-authorized permitting agent for on-site sewage facilities (septic systems) in the unincorporated county, according to TCEQ's own directory of authorized agents⁴. That means most septic installs, alterations, extensions or repairs need a permit from the county's OSSF program rather than from a TCEQ regional office¹³⁵. Reach that office at (830) 776-8027 or [email protected]; TCEQ lists its permit-office location as 500 Quarry St, Eagle Pass, TX 78852¹⁴. Texas law does carve out a narrow 10-acre exemption: if a single-family home sits on 10 or more acres, a licensed site evaluator or engineer signs off, all parts of the system stay at least 100 feet from the property line, effluent stays on the property, and the home is the only dwelling on the tract, no permit is required⁵. Installation is inspected by the county's authorized agent or its designated representative, and any emergency repair must still be reported in writing within 72 hours even though it does not need a permit up front¹⁵⁵.

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

Nothing found on Maverick County's official site or in the state rules on file settles whether you can live in an RV or place a tiny home on unincorporated land long-term⁶. Code Enforcement is the office that would act on any occupancy complaint on unincorporated land, and Planning would know of any subdivision deed restrictions¹²⁷. Call Code Enforcement at 830-773-4669 before you park an RV or place a tiny home long-term, and ask specifically about occupancy limits, utility hookups and any minimum-square-footage rule for a permanent dwelling¹².

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

Confirm your parcel is outside Eagle Pass city limits; the rules described here apply only to unincorporated Maverick County³.
Call the Building Inspector's office at 830-773-4377 to ask whether your specific project needs anything, since the county enforces no general building code but does keep this office¹¹.
Call the Planning Department at 830-773-4377 or [email protected] to ask about platting or subdivision requirements before you buy⁷.
Apply for an OSSF (septic) permit through Maverick County's TCEQ-authorized agent at (830) 776-8027 before installing any septic system, unless your tract qualifies for the state's 10-acre exemption¹⁴⁵.
If your driveway will connect to a state highway, submit TxDOT Form 1058 to the local TxDOT district office and give TxDOT 24-hour notice before construction begins¹⁰.
If your access is instead a county road, contact the Road & Bridge Department at 830-757-1248 or [email protected]¹⁶.
Confirm code-enforcement rules for RVs, tiny homes or temporary occupancy while you build by calling Code Enforcement at 830-773-4669¹².

What to check before you buy land in Maverick County

Maverick County averages about 19.7 inches of precipitation a year, and the county has been in severe drought roughly 32.8% of years on record, so a private well or rainwater plan needs a real drought margin, not just an average¹⁷¹⁸. All of the county's land sits at 15% slope or less¹⁹, and only about 3.6% is wooded²⁰, so most tracts are open, buildable ground rather than cleared-forest lots. No federal land sits inside the county²¹. The nearest city of 100,000 or more people is about 89 miles away in a straight line; Eagle Pass itself is the county's own city and seat²². Typical home insurance in the county runs about $1,449 a year²³, and the effective property tax rate is about 1.4%, with a median annual tax bill around $2,112²⁴²⁵. Farmland has traded at roughly $1,705 an acre and a typical home is valued around $222,798, for scale when comparing raw land to built parcels²⁶²⁷. Confirm flood risk, well-drilling rules and your specific parcel's road access before closing, since none of those are settled by county-wide averages.

Watch-outs

Maverick County's own site does not confirm an owner-builder exemption for unincorporated construction; ask Code Enforcement directly before assuming you can act as your own contractor⁹¹².
TCEQ's directory lists a personal phone number and a personal email address, not a county department line, as the primary contact for Maverick County's septic-permitting authorized agent; confirm that contact is still current before relying on it¹⁴.
