Off-Grid Living in Montmorency County, Michigan

Montmorency County, Michigan, sits in the northeast Lower Peninsula, and it's a place I get asked about a lot because it looks wide-open on a map. The honest answer is that it's off-grid-friendly in some ways and a patchwork in others, and you have to know which level of government you're dealing with for each question.

Zoning is not a county thing here. Montmorency County itself has no countywide zoning ordinance. That authority sits with each individual township under Michigan's Zoning Enabling Act. Montmorency Township has its own zoning ordinance and a Zoning Administrator; Avery Township has a separate one; other townships (Briley, Vienna, etc.) have their own too. So whether you can live on raw land, park an RV long-term, or put up a tiny home depends entirely on which township your parcel is in. I can't give you one countywide answer, and neither can the county, because they'd tell you to call the township hall.

Building permits, on the other hand, ARE handled at the county level. The Montmorency County Building Department, based in the courthouse in Atlanta, issues permits and enforces the Michigan Residential Code for essentially all construction, alteration, or occupancy changes. You need a certificate of occupancy before a structure can legally be used. There's also a Soil Erosion Permit requirement, issued by the county's Soil Erosion Officer, if you're disturbing earth near water or over a certain acreage, and that has to be in hand before the county will issue your building permit.

Septic is regional, not county-run. District Health Department No. 4 (DHD4) covers Montmorency, Alpena, Cheboygan, and Presque Isle counties and administers the Sanitary Code for on-site sewage systems. You need a permit to install a system, and while DHD4's code doesn't stop you from installing a standard system yourself, it does require registration, and alternative treatment systems have tighter rules. Townships can also layer on stricter local rules if they choose.

Greywater, rainwater, and wells don't have a Montmorency- or DHD4-specific ordinance that I could confirm. These appear to default to Michigan's state plumbing and residential codes and the state Water Well Construction Code, locally enforced. If you're planning a greywater system or a rain catchment setup, I'd still call DHD4's environmental health division to confirm there isn't a local wrinkle I'm missing.

Going fully off the utility grid isn't explicitly banned anywhere I found, but practically speaking, the county's certificate-of-occupancy requirement and DHD4's sewage registration mean you'll need a code-compliant water source and sewage system before a dwelling can be legally occupied, even if you never touch a power line.

Bottom line: check your township for land-use and dwelling rules, check the county Building Department for construction permits, and check DHD4 for septic and probably wells.
