Off-Grid Living in Kenedy County, Texas

Kenedy County is about as remote and sparsely populated as Texas gets, and that shows up in the paper trail. When I went looking for a zoning ordinance, a building code, or a septic (OSSF) office specific to Kenedy County, I came up nearly empty. The county's own website doesn't publish planning, zoning, or environmental-health pages that I could find, and there's no Municode or eCode360 host for Kenedy County itself (don't confuse it with the separate City of Kenedy, which sits in Karnes/Wilson/DeWitt Counties, a totally different place). So a lot of this guide is "here's the Texas state default, because I can't confirm the county has layered anything on top of it."

Zoning and dwellings: Texas counties generally don't have the broad zoning power that cities do, and I found nothing suggesting Kenedy County has adopted its own land-use or zoning ordinance. Same story for minimum dwelling size, tiny homes, or RV living rules, nothing county-specific turned up. Texas did give counties limited authority (since 2009) to set some residential construction standards, but I have no evidence Kenedy County has used it.

Building permits: No building-permit office or adopted code was findable on the county's site. Texas has no statewide mandatory building code for unincorporated counties, so unless Kenedy County has quietly adopted an order I couldn't locate, there may be no general building permit requirement here, but that's my inference, not a confirmed fact. Call the county to be sure.

Septic: This one has a real state framework behind it even if the local piece is fuzzy. The Texas Commission on Environmental Quality (TCEQ) oversees on-site sewage facilities (OSSF) statewide. Normally a county health department or environmental office acts as TCEQ's "authorized agent" locally; if a county has no authorized agent, TCEQ's regional office permits directly. I couldn't confirm which applies in Kenedy County. Also worth knowing: state rules carve out a "10-acre rule" exemption from OSSF permitting for a single-family home on 10+ acres meeting certain setback and no-nuisance conditions, per TCEQ.

Greywater and rainwater: No standalone Kenedy County rule on either. Greywater in Texas is generally handled inside the OSSF/septic rules rather than as its own permit. Rainwater harvesting is broadly encouraged under Texas policy and I found nothing restricting it locally.

Wells: No Groundwater Conservation District for the county was confirmed in my research, so Texas's default "rule of capture" for groundwater would likely apply, but I couldn't verify this against an official county or district source.

Utilities: No ordinance requiring grid utility hookups was found, and given the apparent lack of zoning or a building code, disconnected off-grid living looks plausible, just not affirmatively confirmed anywhere official.

Bottom line: this is a place where the paper trail runs out fast, and a phone call to the county and to TCEQ will tell you more than any website search will.
