Off-Grid Living in Alpena County, Michigan

Alpena County is one of those places where the county name on the map doesn't actually tell you much about your rules. Here's the thing I found digging into this: Alpena County has no countywide zoning ordinance. Zoning power sits entirely with the individual townships and with the City of Alpena, each operating under Michigan's Zoning Enabling Act (PA 110 of 2006). So whether you can live off-grid on raw land, park an RV long-term, or build a tiny house depends heavily on which specific township your parcel is in, not on any county rule. Alpena Charter Township has its own zoning ordinance; other townships (Wilson, Long Rapids, Green, Ossineke, etc.) have their own too, and I wasn't able to research each one individually, so check with the specific township clerk or zoning office where your land sits.

Building codes follow the same pattern: no county building department exists. Inside city limits, the City of Alpena's Building Department enforces the state-adopted Michigan Building, Residential, and Rehab Codes. Outside the city, Alpena Charter Township runs its own building department and permitting. Michigan hasn't statewide-adopted the IRC's tiny-house Appendix Q, so any small dwelling still has to meet standard Residential Code minimums as interpreted locally.

Where the county picture gets more consistent is septic and wells, because that's handled by District Health Department No. 4 (DHD4), which covers Alpena, Cheboygan, Montmorency, and Presque Isle Counties together. DHD4 administers a sanitary code requiring a construction permit before you install or repair an onsite sewage system, and its code doesn't stop you from installing your own septic system yourself, provided you get a permit first (alternative treatment systems are treated differently). DHD4 also handles well permitting and site evaluations. I could not confirm whether composting toilets are separately addressed in the DHD4 sanitary code, so ask DHD4 directly before assuming one meets your sewage obligation.

Greywater and rainwater harvesting rules aren't addressed in any Alpena County or DHD4 materials I found, so treat those as governed by Michigan's statewide plumbing code baseline until told otherwise locally.

One more piece worth flagging: Alpena County does administer its own Soil Erosion and Sedimentation Control Ordinance, tied to the state's Part 91 program, and a permit is generally needed for earth-disturbing work over an acre or near lakes and streams, which covers a lot of typical off-grid site prep like driveways, wells, and septic installation.

Bottom line: there is no single "Alpena County rule" for off-grid living outside of septic/well (DHD4) and soil erosion. Zoning and building enforcement is local to your township or the city, so your first call should be to that specific office before you buy land or start building.
