Off-Grid Living in Roscommon County, Michigan

I'll be upfront: Roscommon County itself doesn't run zoning or building departments. Like most Michigan counties, that authority sits with individual townships and villages under the Michigan Zoning Enabling Act and the Stille-DeRossett-Hale Single State Construction Code Act. So almost everything I can tell you about land use and building here comes with the caveat "it depends which township your parcel is in."

Zoning varies township by township. Roscommon Township, for example, has its own zoning ordinance covering land use districts, and it requires a Land-Use Permit before you even put up a shed (anything over 200 square feet also needs a building permit). Denton Township and others each have their own rules. There's no county-wide zoning code, so before you buy or build anywhere in Roscommon County, I'd call the specific township office.

Building permits and codes are also handled locally, not by the county. Denton Township joined with Lake, Markey, Backus, and Roscommon Townships to form the Houghton Lake Building Agency, a joint enforcement body that administers the state construction code across those five townships and employs its own inspector. The Village of Roscommon runs a separate permit process. The county's Buildings & Grounds Department will just point you to your township.

Septic and wells are where the county's role actually shows up, through the Central Michigan District Health Department (CMDHD), which covers Roscommon and five other counties. CMDHD requires a septic permit and a well permit before you can get a building permit, and construction ahead of permit issuance is treated as a violation of the sanitary code. Septic systems here must include a reserve drainfield area, no exceptions. I did not find a specific CMDHD policy on composting toilets, so if that's your plan, call CMDHD directly and ask.

Greywater and rainwater harvesting don't have county-specific ordinances that I could find. That leaves you with the statewide Michigan Plumbing/Residential Code baseline administered by LARA, which is generally permissive, but I'd confirm nothing local overrides that.

Full utility disconnection (no well, no septic, no grid) is a genuine gray area. I found no explicit township or county ban on going off-grid for power and heat. But because CMDHD requires an approved well and septic permit before a building permit gets issued, a legal occupancy pathway effectively assumes you have permitted water and sewage systems, even if they're private ones like a well and septic rather than municipal service. Whether a county inspector would sign off on a truly off-grid setup (composting toilet, no well) isn't confirmed in what I found. Ask CMDHD and your township building official directly before you commit to a plan.

Bottom line: this is a county where the real rulebook is written locally. Find out which township your land sits in, then call that office first.
