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

Zoning & raw-land occupancy

Generally allowedThe Macon County Commission confirms the county has no planning or zoning department, so unincorporated land has no county-level use restrictions. The City of Macon has its own separate zoning code enforced by its Code Enforcement Official. source

Dwellings, tiny homes & RVs

Varies locallyNo county building or zoning code restricts dwelling type or RV residency in unincorporated Macon County, but inside the City of Macon the city's own building/zoning code applies. source

Building permits & codes

Varies locallyMissouri's statewide dataset shows Macon County has adopted no residential or energy building code countywide. The City of Macon runs its own Code Enforcement office requiring permits and inspections within city limits. source

Septic & composting toilets

RestrictedMissouri's state '701 law' (RSMo 701.025-701.059) requires permitting for most onsite wastewater systems, administered by DHSS with local complaint handling by the Macon County Health Department. Composting toilets aren't addressed in available sources, so ask the health department. source

Greywater reuse

Unclear - verifyNo Macon County or Missouri state rule specifically on residential greywater reuse was found; not confirmed either way. Check with the Macon County Health Department directly.

Rainwater harvesting

Generally allowedNo Macon County ordinance restricting rainwater collection was found, so this appears to follow the general Missouri baseline allowing it.

Private wells & water rights

RestrictedWells are governed entirely by Missouri DNR under the Water Well Drillers Act and Well Construction Rules (10 CSR 23), with no county permitting layer. Landowners can self-install a well without a permit but must meet state construction standards. source

Living disconnected from utilities

Generally allowedWith no countywide zoning or building code requiring utility hookups, off-grid living without electric or water utility connections is not prohibited in unincorporated Macon County; only state septic/well rules or a city's own code (if inside town limits) would apply.
