Read this before you act on anything below. This is my researched starting point for Charlevoix County, MI, 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 rulesCharlevoix County, MI

Zoning & raw-land occupancy

Varies locallyCharlevoix County has no general zoning; each city/township (except Boyne Falls, which has none) sets its own zoning ordinance and administrator. Check with the specific township or city for your parcel. source

Dwellings, tiny homes & RVs

Unclear - verifyNo county-specific tiny home or RV occupancy ordinance was found; the state construction code baseline applies and township rules (like the City of Charlevoix's) may add requirements. Confirm with your local zoning administrator. source

Building permits & codes

RestrictedThe Charlevoix County Department of Building Safety enforces the state construction code and requires a building permit application tied to zoning, septic, well, and other approvals. source

Septic & composting toilets

RestrictedSeptic systems require a permit from the Health Department of Northwest Michigan under the district sanitary code covering Charlevoix, Antrim, Emmet, and Otsego Counties; composting toilets are not explicitly addressed, so ask HDNW. source

Greywater reuse

Unclear - verifyNo Charlevoix County or HDNW page specifically addresses greywater reuse; it may be folded into septic permitting, but this is not confirmed. Ask HDNW directly.

Rainwater harvesting

Unclear - verifyNo county-specific rainwater harvesting rule was found; the state plumbing code baseline appears to apply without noted local modification.

Private wells & water rights

RestrictedWells require a permit from HDNW under the same district sanitary code as septic, and new wells require bacteriological and chemical testing as part of that permit. source

Living disconnected from utilities

Unclear - verifyNo ordinance explicitly bans disconnecting from utilities, but building permits require attached septic and well permits, making approved water/waste systems a practical prerequisite for legal occupancy. source
