Off-Grid Living in Gratiot County, Michigan

I'll be upfront: Gratiot County, Michigan is one of those places where the answer to "can I do this off-grid?" almost always starts with "it depends which township you're in." That's not me dodging the question, it's just how the county is set up.

Zoning is split. Gratiot County directly administers zoning for six townships: Lafayette, Sumner, North Star, Hamilton, Newark, and Elba. Every other township and city in the county runs its own separate zoning ordinance. So the very first thing I'd do before buying land here is call whichever township the parcel sits in and ask who actually holds zoning authority over it, the county or the township itself.

Dwellings, tiny homes, RVs. I only found one township-level example (Arcada Township) that spells out RV/camping rules, and it treats RVs and travel trailers used as temporary dwellings as a time-limited camping use, not a permanent housing solution. I can't confirm that's countywide policy, only that it reflects the general Michigan pattern of RVs being treated as temporary occupancy. For a permanent tiny home, you'd be building to the state's residential code (administered by Michigan's LARA) since I didn't find a Gratiot-specific tiny-home or Appendix Q allowance.

Building permits run through the Gratiot County Department of Community Development for the six county-zoned townships, and that office also issues Certificates of Occupancy, meaning your build isn't legally finished (or occupiable) until they sign off. A township zoning permit or approval letter has to come first, before the county will even issue a building permit.

Septic and wells are both handled by the Mid-Michigan District Health Department (MMDHD), which covers Gratiot, Clinton, and Montcalm counties together. You need an approved septic permit and well permit before a building permit gets issued, no way around that in the standard permitting chain. Existing systems can sometimes be reused, but if a well or septic setup has sat unused for a long stretch, MMDHD wants an evaluation submitted first.

Greywater and rainwater aren't addressed in any Gratiot- or MMDHD-specific rule I could find. That means you're falling back to Michigan's statewide plumbing code (greywater) and the state's rainwater harvesting law, both administered at the state level through LARA.

Full utility disconnection isn't explicitly banned by any Gratiot ordinance I found, but practically, you can't get a Certificate of Occupancy without an approved water and septic/well setup already in place. So living totally off-grid, no permits, no hookups, is really only feasible on land you're not trying to legally "build" on in the county's eyes.

Bottom line: this is a county where the paperwork chain (township zoning permit → county building permit → MMDHD well/septic permit → Certificate of Occupancy) all locks together, and confirming which office has jurisdiction over your specific parcel is step one, not an afterthought.
