Off-Grid Living in Oscoda County, Michigan

I'll be upfront: Oscoda County, Michigan is one of those places where you can't just look up "the county rule" and be done with it. The layers of government here split responsibilities in a way that trips people up, so let me walk through it carefully.

Zoning is not a county thing here. Oscoda County has no countywide zoning ordinance. Instead, each township decides land use for itself under Michigan's Zoning Enabling Act. I looked at Mentor Township's ordinance as an example, it splits the township into zones like an AuSable River Zone, a Green Belt Zone, residential districts, and a recreational-agriculture zone, each with its own rules. Whatever township your land sits in will have its own version (or, in some unzoned townships, possibly no zoning at all). There's also a mix-up worth flagging: "Oscoda Charter Township" is actually in Iosco County, not Oscoda County, so don't mistake its ordinance for a local one if you're researching parcels here.

Building permits, on the other hand, ARE centralized at the county level. The Oscoda County Building Department issues permits and does inspections for building, electrical, plumbing, mechanical, and soil erosion work, regardless of township. Their permit form asks you to specify your water supply and sewage disposal type, which tells you they expect an approved solution, whether that's municipal, well, or septic, before signing off.

Septic and wells are handled by a health district, not the county itself. District Health Department No. 2 (DHD2) covers Oscoda, Alcona, Iosco, and Ogemaw Counties under state public health law. You need a construction permit before installing or repairing a septic system, which involves a site visit and soil evaluation, and a final inspection before you backfill. Wells go through the same office and same application. I didn't find anything specific about composting toilets, so I'd call DHD2's Environmental Health division directly to ask how they're treated.

Greywater and rainwater harvesting don't have county- or district-specific rules that I could confirm, so I'm treating those as falling back on Michigan's state plumbing code baseline. It's worth double-checking with DHD2 since greywater sometimes gets folded into septic regulation.

Full off-grid disconnection (no septic, no well, nothing) isn't explicitly addressed anywhere I found. Given the building permit's language, it looks like the county's expectation is that you'll have an approved well and septic setup, that's the sanctioned "off-grid" path here, rather than going without any water/sewage system at all.

Bottom line: check your specific township for zoning and dwelling-type questions, call the county for building permits, and call DHD2 for well and septic. Don't assume one office speaks for all three.
