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

Zoning & raw-land occupancy
RestrictedLafayette County is unusual for rural Missouri in that voters adopted countywide zoning, so the Planning & Economic Development office oversees land use in unincorporated areas. If your land is inside a city's limits, you'd deal with that city hall instead. source
Dwellings, tiny homes & RVs
Unclear - verifyThe county's 2016 Land Development Code and Comprehensive Plan govern dwelling standards in unincorporated areas, but I couldn't confirm specifics on tiny homes, minimum square footage, or living in an RV from an official Missouri source. Call the county Planning office directly for the current code text. source
Building permits & codes
Unclear - verifyThe Planning & Economic Development office handles building permits in unincorporated parts of the county, including things like sheds, but I could not confirm which specific building code edition (IRC, IBC, etc.) is currently adopted. Ask the office directly before you plan a build. source
Septic & composting toilets
RestrictedLafayette County has its own onsite wastewater ordinance that goes beyond Missouri DHSS's baseline state minimum standards, according to DHSS's own county lookup tool. Composting toilets aren't separately addressed, so treat any alternative system as subject to local health department review. source
Greywater reuse
Unclear - verifyI found no Lafayette County or Missouri state page specifically addressing greywater reuse, so this is genuinely unsettled. Ask the Lafayette County Health Department directly before setting up a greywater system.
Rainwater harvesting
Generally allowedNo Lafayette County ordinance restricting rainwater collection turned up in my research, so the general state-friendly baseline appears to apply. Still, it's worth confirming with County Planning that no local rule adds conditions.
Private wells & water rights
RestrictedPrivate wells across Missouri fall under DNR's statewide Well Construction Rules, and the Lafayette County Health Department fields questions and complaints about private wells and cisterns locally. Check with both DNR and the county health department before drilling. source
Living disconnected from utilities
Generally allowedI found no Lafayette County ordinance requiring hookup to public utilities or banning off-grid living outright. That said, any structure you build still has to satisfy the county's zoning, building, well, and septic rules covered above.
