Off-Grid Living in Worth County, Missouri

I'll be upfront: Worth County, Missouri is one of the harder places for me to research because there's simply no dedicated county government website with published zoning, building, or health ordinances that I could find. It's a tiny, rural county (population under 2,000, county seat Grant City) and small northwest Missouri counties like this frequently haven't adopted the kind of formal land-use codes you'd find in a suburban county. So a lot of what follows is "here's the state baseline, and here's what I couldn't confirm locally."

Zoning. Missouri counties only get zoning authority once they adopt it under state law (Chapter 89), usually through a planning and zoning commission. I found no evidence Worth County has ever created one. That suggests unincorporated land may be unregulated for land-use purposes, but I can't confirm that absence definitively, so treat it as likely rather than certain, and call the County Commission to check.

Dwellings, tiny homes, RVs. No county ordinance on this surfaced in my research. Absent confirmed zoning or a building code, there may be no formal restriction outside Grant City limits, but I wasn't able to pull Grant City's own municipal code, so if you're inside town, don't assume the same freedom applies.

Building permits. Missouri has no statewide building code, adoption is a local, county-by-county or city-by-city choice. I found no evidence of a Worth County building department or permit ordinance.

Septic. This one is state-level for sure. Missouri's Department of Health and Senior Services runs the Onsite Wastewater Treatment (OWTS) program statewide, but the actual permitting authority varies by county, some counties handle it locally, others default straight to DHSS. I couldn't confirm which applies to Worth County, so use DHSS's county lookup tool or call their Onsite Program directly.

Greywater. No state statute or Worth County rule addressing this was found. It's genuinely an open question, ask DHSS.

Rainwater harvesting. Missouri state law protects your right to collect rainwater on your own property, and I found nothing at the county level overriding that.

Wells. Regulated statewide by Missouri DNR under the Water Well Drillers Act and well construction rules, no county-specific wrinkle found for Worth County.

Off-grid utilities. State law protects using a private water system instead of hooking to utilities, subject to DNR's well rules. No Worth County ordinance mandating hookup turned up in my search.

Bottom line: for anything county-specific here, your fastest path is a phone call to the Worth County Commission, since there's no separate planning or building office listed anywhere official that I could find.
