Off-Grid Living in Charlevoix County, Michigan

I've been digging into what off-grid living actually looks like in Charlevoix County, Michigan, and the short version is: there's no single "Charlevoix County rule book." Land use here is a patchwork, and you need to know which authority governs which piece of your plan.

Zoning is local, not county-wide. Charlevoix County itself doesn't have a general zoning ordinance. Instead, each township and city (Charlevoix, Boyne City, East Jordan, and the various townships) writes and enforces its own zoning, with its own Zoning Administrator. The one exception is the Village of Boyne Falls, which has no zoning at all. The County Planning Department mostly handles floodplain, wetlands, and coordination with state agencies like EGLE, not parcel-level decisions. So the very first call I'd make is to whichever township or city office covers your specific parcel, because rules on minimum dwelling size, RVs, and setbacks vary a lot from one to the next.

Building permits run through the county. The Charlevoix County Department of Building Safety enforces the state construction code and requires a building permit application that references your other approvals, zoning, driveway, septic, well, soil erosion, and wetlands permits. So building, septic, and well approvals are meant to work together as one package.

Septic and wells go through the Health Department of Northwest Michigan (HDNW), which administers a district sanitary code covering Charlevoix, Antrim, Emmet, and Otsego Counties. You need a permit before installing, repairing, or extending a septic or water supply system, and new wells require bacteriological and chemical testing as part of that permit. I did not find a Charlevoix-specific composting toilet policy, so I'd ask HDNW directly how they treat that.

Greywater and rainwater harvesting are genuinely unclear here. I couldn't find a county or HDNW page that spells out rules for either one specifically. My guess is greywater disposal gets folded into septic permitting review, but that's not confirmed, so ask HDNW before you build a separate system.

Full utility disconnection isn't explicitly banned or blessed. No ordinance I found says you can't live entirely off-grid, but the permitting chain (building permit needs septic and well permits attached) makes an approved water and waste system a practical requirement for a legal occupancy, even in the absence of a formal "you must connect" rule.

Bottom line: this is a county where the state's baseline rules apply unless a township tightens them, and success depends heavily on picking the right parcel and calling the right office before you buy.
