Off-Grid Living in Saginaw County, Michigan

I've been digging into what it actually takes to live off-grid in Saginaw County, Michigan, and the first thing I want you to understand is a structural quirk: Michigan counties don't do countywide zoning. Saginaw County itself has no planning/zoning department with land-use authority. That job belongs to the 27 individual townships and cities inside the county, places like Saginaw Charter Township or the City of Saginaw, each running its own zoning ordinance under the state Zoning Enabling Act. So the honest first answer to "can I put a cabin or tiny home on this land" is: it depends entirely which township or city the parcel sits in. Call that local office before you buy anything.

Where the county does step in directly is environmental health, meaning septic and well permitting, run by the Saginaw County Health Department under its Environmental Health Code. If your property isn't hooked to public water and sewer, you'll need a wastewater disposal permit and a well permit from that office, and their process includes a site evaluation for septic suitability, buildable soil conditions, and a permit that's valid for a set period once issued. Wells have to be installed by a state-licensed driller under Michigan's Water Quality Law, and if you're replacing an old well, plan on properly abandoning it. Composting toilets aren't mentioned anywhere in what I found for the county, so I'd call the Health Department directly and ask how they'd treat one instead of assuming it sidesteps the septic permit.

Building permits and codes are also handled locally, not by the county, using state-adopted codes (Michigan Building Code, Residential Code, Plumbing, Mechanical, and the National Electrical Code, all with state amendments). The City of Saginaw layers in FEMA flood-zone requirements on top of that for some parcels, so flood mapping matters if you're near water.

Greywater reuse and rainwater harvesting don't show up in any Saginaw County-specific ordinance I could find, so both appear to just follow the state plumbing code baseline, rainwater harvesting looking fine, greywater less clearly spelled out. I'd confirm directly with the Health Department if you're planning a real greywater system rather than just watering the garden.

On full utility disconnection, I couldn't find anything in county or township sources that directly addresses cutting the electrical grid connection. What is clear is that going without public water and sewer is legal only through the county's well and septic permitting, not through simply skipping infrastructure altogether. So "off-grid" here means permitted, self-contained water and waste systems, not a regulatory blank slate.

Bottom line: treat this as two separate governments to satisfy, your township or city for zoning and building, and Saginaw County Health Department for well and septic. Confirm everything locally before committing to land.
