Read this before you act on anything below. This is my researched starting point for Monroe 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 rulesMonroe County, MO

Zoning & raw-land occupancy

RestrictedMonroe County has adopted countywide zoning, enforced by the Planning and Zoning Commission, County Court, and an Administrative Officer, per the county's zoning regulations. source

Dwellings, tiny homes & RVs

Unclear - verifyNo specific Monroe County provision on tiny homes or RV residency was found; the zoning ordinance sets lot/yard requirements but dwelling-type specifics aren't confirmed. Ask the county Planning & Zoning office directly.

Building permits & codes

Varies locallyBuilding permits are issued locally through the Monroe County Clerk's Office in Paris, but no adoption of a specific statewide model code was found; Missouri has no uniform statewide building code, so this is set locally. source

Septic & composting toilets

RestrictedThe Monroe County Health Department requires a permit before constructing, installing, or modifying any wastewater treatment system, with setback and fencing rules for lagoons, layered on top of Missouri DHSS's statewide minimum standards. source

Greywater reuse

Unclear - verifyNo Monroe County or Missouri DHSS/DNR rule specific to greywater reuse was found; check directly with the Monroe County Health Department.

Rainwater harvesting

Generally allowedNo Monroe County ordinance restricting rainwater collection was found, and Missouri generally does not restrict the practice.

Private wells & water rights

RestrictedWell construction is governed entirely at the state level by Missouri DNR under the Water Well Drillers Act and Well Construction Rules; landowners who drill their own well and install their own pump are exempt from the permit but must follow all other construction rules. source

Living disconnected from utilities

Generally allowedNo Monroe County ordinance was found prohibiting off-grid utility disconnection; septic and well compliance are the real constraints rather than a mandatory hookup rule.
