Off-Grid Living in Tuscola County, Michigan

Tuscola County, Michigan is a patchwork when it comes to off-grid living, and I want to be upfront about that before I get into specifics. The county itself has no countywide zoning ordinance. Instead, each of the county's townships (there are thirty-four communities in the county) adopts and enforces its own zoning under the state's Michigan Zoning Enabling Act. That means whether you can put a tiny home, RV, or off-grid cabin on raw land depends entirely on which township that land sits in, not on a single county rule. I've seen this in ordinances from Columbia, Denmark, and Millington Townships, all of which regulate land use independently, each citing the same state enabling act but writing their own local rules.

Where the county does step in with one consistent rule is building permits. Tuscola County contracts with SAFEbuilt to handle building, electrical, mechanical, plumbing, and soil erosion permitting and inspection countywide, with the notable exception of Tuscola Township and Arbela Township, which handle this themselves. So if you're building any structure, expect to go through SAFEbuilt (or your township directly, in those two cases) and to clear your township's zoning administrator first, since zoning approval is generally required before a building permit is issued.

Septic and well matters run through the Tuscola County Health Department's Environmental Health division, which handles sewage disposal permits and well permitting/inspection countywide. Well construction itself follows Michigan's statewide Water Well Construction Code, administered by EGLE, with local health department staff doing the on-the-ground inspection and permitting. I did not find anything in the county's official sources addressing composting toilets specifically, so that's a question mark you'll want to run past the health department directly rather than assume either way.

Greywater and rainwater harvesting rules are not something I could confirm at the county or township level. In the absence of a local ordinance, my read is that Michigan's state plumbing code, administered by LARA, sets the baseline, and I haven't found any Tuscola-specific deviation from that either restricting or expanding on it.

Living fully disconnected from utilities (no grid electric, no municipal water) isn't explicitly addressed anywhere I found, but in practice, the septic/well approvals and building permit sign-off from the health department and building department function as gatekeepers for occupancy, so full off-grid living is workable in principle but subject to those same approval chains.

Bottom line: the county sets the building and health/septic/well framework, but zoning, the piece that determines whether your specific plan is even allowed on your specific parcel, is a township-by-township question you need to answer before doing anything else.
