Off-Grid Living in Otsego County, Michigan

I'll be upfront: Otsego County, Michigan is one of the more interesting cases I've researched, because unlike most Michigan counties (where townships hold all the zoning cards), Otsego County itself has adopted a countywide zoning ordinance through its Department of Land Use Services. That's unusual. But it doesn't simplify things for off-gridders, because the City of Gaylord, the City of Otsego, and organized townships like Otsego Township all run their own separate zoning codes inside their borders. So the very first thing I'd tell anyone eyeing land here is: figure out exactly which jurisdiction your parcel sits in before you assume anything about what's allowed.

On zoning and raw land, the county's ordinance covers unincorporated territory with ten zoning districts, but incorporated cities and some townships opt out with their own rules on minimum acreage and permitted uses. For dwellings, tiny homes, and RVs, I could not find a clear countywide rule specifically addressing tiny houses or RV-as-permanent-residence. The county's dwelling definition does seem to assume utility connections are part of the picture, but Michigan hasn't adopted Appendix Q (the tiny-home code addition) statewide, so this is genuinely murky and worth a direct call to the county.

Building permits are firmly required, administered by the Otsego County Building Department, which enforces the state-adopted Michigan Residential Code (2015) plus plumbing, mechanical, and fuel gas codes set by the state. Notably, even a Temporary Certificate of Occupancy requires basics like heat, running water, a bathroom, cooking facilities, and smoke detectors, meaning full off-grid living without those systems in place is not straightforward, even temporarily.

Septic and wells are handled not by the county but by the Health Department of Northwest Michigan (HDNW), which enforces a District Sanitary Code shared across four counties. Both septic systems and water wells require permits under that code, on top of the state's water well construction rules from EGLE. I did not find anything specific on composting toilets as a septic alternative here, so that's a direct question for HDNW.

Greywater reuse and rainwater harvesting don't appear to have county-specific ordinances; both default to the statewide plumbing and residential codes. That generally means they're allowed, but there's no local program or restriction spelled out.

Living fully disconnected from the grid is the fuzziest area. There's no outright ban on solar-only power that I found, but water and sewage still have to go through HDNW's permitted systems, and building occupancy standards lean against total self-sufficiency. My honest read: doable, but you'll be threading a needle between county, health department, and possibly city or township rules.
