Off-Grid Living in Missaukee County, Michigan

I'll be upfront: Missaukee County, Michigan is one of those places where the answer to "is off-grid living legal here?" is genuinely "it depends which township line you're standing on." There's no single county-wide zoning ordinance that governs everything. Instead, the county's Building Department confirms that of the 14 townships in Missaukee, some have adopted their own zoning ordinances under the state's Michigan Zoning Enabling Act, and where that's happened, the township's rules control, not the county's. Only the City of Lake City and City of McBain have their own municipal zoning regs, and if you're inside those city limits you deal directly with the city zoning administrator. Everywhere else, the county building department itself tells applicants to check for deed restrictions and call the Township Supervisor before assuming anything. So my first, honest piece of advice: don't trust a blanket answer for "Missaukee County" as a whole, call your specific township.

On dwellings, I've seen commercial off-grid sites claim there's a 720-square-foot minimum size ordinance here banning tiny homes. I could not verify that on any official county or city page, so I'm treating it as not confirmed rather than repeating it as fact. What is confirmed: placing a manufactured or modular home requires a county Building Permit package, which includes well/septic approval, and, inside Lake City or McBain, a separate city Land Use Permit.

Building permits themselves are handled countywide by the Missaukee County Building Department, covering building, electrical, mechanical, plumbing, and soil erosion/sedimentation permits. You're allowed to act as your own general contractor on your own home without a residential builder's license, but you're still on the hook for every permit, inspection, and code fix. The county follows the 2015 Michigan Residential Code, including its rule that a permit expires if work hasn't started or has been abandoned for a set period, so don't let a permit sit idle.

Water and waste run through District Health Department #10 (DHD#10), which covers Missaukee and nine neighboring counties. DHD#10 issues well and septic permits, does site evaluation, and inspects final work. Homeowners can install their own septic system themselves; other installers need to be DHD#10-licensed. I found no Missaukee-specific rule on composting toilets as a septic substitute, so treat that as an open question for DHD#10.

Greywater reuse and rainwater harvesting don't appear to have any county-specific rules layered on top of Michigan's state plumbing code, so both default to the state baseline as far as I could confirm.

There's no standalone ordinance banning full grid disconnection that I could find, but going off-grid on water and sewage in practice means going through DHD#10's permit process before a building permit gets issued, so full self-sufficiency without any official sign-off isn't really an option here.
