Read this before you act on anything below. This is my researched starting point for Reynolds County, MO, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesReynolds County, MO

Zoning & raw-land occupancy

Unclear - verifyNo official Reynolds County planning or zoning ordinance was found, and Missouri law requires voter approval for county zoning, which I found no evidence of here. Treat unincorporated land as likely unzoned but unconfirmed.

Dwellings, tiny homes & RVs

Varies locallyNo county rule on dwelling size, tiny homes, or RVs was found, so unincorporated areas appear unregulated. Incorporated towns like Bunker, Ellington, and Centerville set their own separate rules through city hall.

Building permits & codes

Generally allowedMissouri's state dataset confirms Reynolds County has adopted no IECC or IRC building code countywide. Towns within the county, such as Bunker, run their own independent permitting. source

Septic & composting toilets

RestrictedMissouri DHSS sets statewide OWTS standards, and the Reynolds County Health Center administers septic permitting, site evaluations, and complaints locally. source

Greywater reuse

Unclear - verifyNo Missouri state statute or Reynolds County rule specific to greywater reuse was found. Confirm directly with the Health Center before building a system.

Rainwater harvesting

Generally allowedNo Reynolds County ordinance restricts rainwater collection, so the county follows Missouri's general permissive statewide baseline.

Private wells & water rights

RestrictedWells are governed by Missouri DNR's statewide Well Construction Rules, not a county ordinance. The Reynolds County Health Center separately offers private well water bacterial testing. source

Living disconnected from utilities

Generally allowedNo Reynolds County ordinance requires connection to public power or water, so living off-grid for utilities appears permitted at the county level.
