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

Zoning & raw-land occupancy

RestrictedGreene County has countywide zoning under Missouri Revised Statutes 64.211-64.295, adopted via a 1986 Zoning Ordinance covering all unincorporated land; the Planning and Zoning office maintains the map and permits. This does not apply inside any city limits, where municipal code governs instead. source

Dwellings, tiny homes & RVs

RestrictedThe county ordinance regulates travel-trailer parks and gives the County Commission authority over their design and operation, suggesting RV living outside a permitted park is controlled; a specific tiny-home rule was not confirmed in county materials. source

Building permits & codes

RestrictedGreene County has adopted the 2012 International Codes and 2011 National Electric Code with local amendments, and Building Regulations issues permits for all phases of construction in unincorporated areas. source

Septic & composting toilets

RestrictedA permit from Building Regulations is required for new septic installation or for repair/replacement of an existing system, built to the county's own on-site wastewater design standards. Composting toilets are not separately addressed, so that piece is not confirmed. source

Greywater reuse

Unclear - verifyNo Greene County or Missouri state page specifically addressing greywater reuse was found; ask the county's Environmental Division directly before installing a system.

Rainwater harvesting

Generally allowedNo Greene County ordinance restricting rainwater collection was found, so the general state allowance applies.

Private wells & water rights

RestrictedWell construction standards are set at the state level by Missouri DNR, while the Springfield-Greene County Health Department offers testing for nitrates and bacteria, and the county's Environmental Division weighs in on well/septic need during construction review. source

Living disconnected from utilities

Generally allowedNo county ordinance bans disconnecting from utilities, but any structure still needs the same building, septic, and well permits described above, and some projects require plans sealed by a state-licensed design professional. source
