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

Zoning & raw-land occupancy

Unclear - verifyNo official Douglas County zoning ordinance or map was found. Missouri law (Chapter 64 RSMo, state statute) requires voter approval before a county like this can adopt zoning, and many rural Ozark counties never have, so there's likely no countywide zoning, but this isn't confirmed by a county document. Ava, the only incorporated city, may have separate municipal zoning. source

Dwellings, tiny homes & RVs

Unclear - verifyNo Douglas County ordinance on tiny homes, minimum dwelling size, or RV living was found. This likely defaults to the state baseline (no restriction) if there's no local zoning or building code, but that is not confirmed.

Building permits & codes

Unclear - verifyMissouri has no statewide building code; adoption is a local, county-by-county choice. No evidence of a Douglas County building department or adopted code was found, suggesting permits may not be required in unincorporated areas, but this is not verified. source

Septic & composting toilets

RestrictedNo standalone Douglas County health department for septic permitting was confirmed, so the Missouri Department of Health and Senior Services (DHSS) Onsite Wastewater Treatment Program is the fallback state authority for individual septic systems here. source

Greywater reuse

Unclear - verifyNo Missouri state statute or Douglas County ordinance specifically addressing greywater reuse was found. Ask DHSS or the local septic permitting authority before planning a greywater system.

Rainwater harvesting

Generally allowedRainwater harvesting is protected under Missouri's statewide baseline rules, and no Douglas County ordinance modifying that was found.

Private wells & water rights

RestrictedPrivate well construction statewide, including in Douglas County, is governed by the Missouri Department of Natural Resources (DNR) Water Well Drillers Act and Well Construction Rules. No county-specific well ordinance was found.

Living disconnected from utilities

Generally allowedMissouri's state baseline generally allows reliance on a private well instead of utility hookup, subject to DNR well rules, and no Douglas County ordinance requiring utility connection was found.
