Buying Land in Gonzales County, Texas
Gonzales County, birthplace of Texas independence and sitting over both the Eagle Ford Shale and the Gulf Coast Aquifer, just replaced its entire subdivision rulebook for the first time in over a decade -- a real, dated, and specific regulatory shift for anyone planning to divide land here.
A brand-new subdivision ordinance, not an incremental update
Gonzales County's Commissioners Court unanimously adopted a completely rewritten, 149-page subdivision ordinance on October 28, 2024 -- the county's first new set of platting and permitting rules in more than 12 years, replacing regulations originally adopted in 2007 and last amended in 2012. This wasn't a minor cleanup: the new ordinance was drafted by an outside land-use attorney and adopted after commissioners-court workshops that reportedly included tense public exchanges over the pace of adoption and its effect on development conditions in the county. The most consequential single change for anyone planning to subdivide land here is a road-frontage minimum that jumped from 50 to 100 feet, a shift local reporting describes as intended to effectively end new flag-lot subdivisions (long, narrow lots that reach a public road through a thin strip rather than full frontage). See the standalone subdividing-land page below for the ordinance's other provisions, including driveway spacing and minimum lot sizes.
Groundwater: a two-county district with recently updated rules
Gonzales County's groundwater is managed by the Gonzales County Underground Water Conservation District (GCUWCD), which jointly covers both Gonzales and Caldwell counties rather than serving Gonzales alone -- a structural detail worth knowing since it means the district's board, notice requirements, and rulemaking process all span two counties at once. A new well permit application (required for a well producing more than 25,000 gallons a day; smaller wells register as exempt) must be publicly noticed in newspapers of largest circulation in both Gonzales and Caldwell counties, with a 30-day public-comment period beginning after the last publication and the district's board meeting on the second Tuesday of each month to act on completed applications. The district's current rules carry a November 11, 2025 date, making this a genuinely recently updated framework -- confirm current requirements directly with GCUWCD (830-672-1047) before drilling a non-exempt well.
Septic permitting: handled directly by the county
Unlike a county that routes OSSF applications through a TCEQ regional office, Gonzales County runs its own septic permitting program, with a posted permit checklist covering the site-evaluation and application process. That means working directly with the county's own environmental health and code enforcement staff rather than a state regional office -- generally a faster, more locally responsive process, though it's still worth confirming current fees and any local supplemental requirements directly with the county rather than assuming the statewide 30 TAC 285 minimums are all that applies.
Who to Call Before Buying Land in Gonzales County
Gonzales County has no zoning department because unincorporated Gonzales County is not zoned. For land inside the City of Gonzales or another incorporated town, contact that city's own planning department instead of the county, since its own zoning and subdivision rules would apply there rather than the county's.
