Off-Grid Living in Randolph County, Missouri

I dug into Randolph County, Missouri's official sources to see what off-grid living actually looks like there, and honestly, it's a mixed bag of "not much regulation" and "a couple things you really do need to check."

Zoning: I couldn't find a countywide zoning ordinance on the Randolph County Commission's own ordinance list. That page names a handful of specific ordinances (utility, UTV/golf cart, drone, wastewater/solid waste) but zoning isn't among them. This tracks with Missouri's state law (Chapter 64 RSMo), which requires voter approval before a county like Randolph adopts planning and zoning, and many similarly sized counties never have. That means if you're out in unincorporated Randolph County, zoning as a barrier to off-grid living is likely a non-issue, but towns like Moberly, Huntsville, Cairo, Clark, and Clifton Hill each set their own rules inside city limits, so that distinction matters a lot for where you buy land.

Dwellings and tiny homes: I found nothing at the county level addressing minimum home size, tiny homes, or RV living. Given no county zoning, my read is this is unregulated outside town limits, but Moberly's Planning & Zoning Commission would be the one to ask if you're inside that city.

Building codes: Missouri's own statewide dataset shows Randolph County with no adopted residential or energy code. That's the norm for the state, not the exception.

Septic: This is where the county actually has teeth. The Randolph County Health Department maintains its own on-site wastewater ordinance and application process, so septic systems are locally regulated, layered on top of Missouri DHSS's statewide minimum standards for onsite wastewater treatment systems. Composting toilets aren't addressed anywhere I found, so I'd call the health department directly before assuming you can skip a permitted septic system.

Greywater: No state or county rule specifically on greywater reuse turned up in my research. Ask the Randolph County Health Department whether their wastewater ordinance touches this.

Rainwater: Nothing in county sources restricts collecting rainwater, so this follows Missouri's general allowance for landowners.

Wells: Private wells fall under Missouri's statewide Water Well Drillers Act and Well Construction Rules (10 CSR 23), administered by DNR, not a county-specific ordinance. If you'd rather connect to a public system, Thomas Hill PWSD No. 1 serves part of the county.

Utilities: I found nothing compelling a mandatory hookup to public utilities for people relying on well and septic, though the county's own "Utility Ordinance" is worth confirming with the County Commission for specifics.

Bottom line: county-level rules are light except for septic, where Randolph County Health has real authority, and wells, which are a state matter statewide.
