Off-Grid Living in Texas County, Missouri

I'll be upfront: Texas County, Missouri is one of those places where the honest answer to a lot of off-grid questions is "nobody's written that rule down officially." I dug through what I could find at the county and state level, and here's where things stand.

Zoning. I could not find any official Texas County planning or zoning department, ordinance, or zoning map. Missouri's Chapter 64 RSMo requires voters to approve county planning and zoning before it exists, and based on the absence of any county page on this, it looks like Texas County hasn't gone that route. That means, as far as I can confirm, unincorporated land in the county isn't zoned. That's good news for off-gridders in general, but I'd still call the County Clerk or Commission to double-check nothing's changed recently, since I couldn't find an official page to verify against.

Dwellings, tiny homes, RVs, building permits. Same story: no county building department, no adopted building code (Missouri doesn't require one statewide, and adoption is a local option), no minimum square footage rule that I could locate. Practically, that suggests unincorporated Texas County is pretty permissive on structures, but "I couldn't find a rule" isn't the same as "there is no rule." Confirm with the County Commission before you build.

Septic. This is where real regulation kicks in, run by the Texas County Health Department under Missouri's statewide onsite wastewater program. Since 1996, Missouri has required a permit to construct for any on-site sewage system except a single-family home on 3+ acres. Since 2004, installation must be done by a state-registered installer. You'll need a soils morphology report before a system gets designed, and if conventional systems don't work, an engineer has to design an alternative, sometimes a lagoon if setbacks allow. If a system gets a violation notice, a permit is required to fix it regardless of acreage. Composting toilets aren't addressed on the county's page, so ask directly.

Greywater. Not addressed anywhere I found, county or state. Call the Health Department for their read on it.

Rainwater harvesting. No restriction found at the county or state level, so this appears freely permitted.

Wells. Regulated statewide by Missouri DNR's Well Construction Rules; you need a permitted driller, and the county Health Department offers well water testing as one of its services, recommended annually for bacteria and every few years for heavy metals.

Utility disconnection. No ordinance requiring hookup to public water, sewer, or electric was found, so living off-grid utility-wise appears permitted, subject to the septic/well rules above.

Bottom line: Texas County looks light on land-use regulation but serious about wastewater and well construction through its Health Department. When in doubt, call before you build or drill.
