Read this before you act on anything below. This is my researched starting point for Otsego County, MI, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesOtsego County, MI

Zoning & raw-land occupancy

Varies locallyOtsego County has its own countywide zoning ordinance covering unincorporated areas with ten zoning districts, but the City of Gaylord, City of Otsego, and organized townships like Otsego Township run their own separate zoning codes. Which rules apply to a raw parcel depends entirely on which jurisdiction it sits in, so I'd start with the county's Planning & Zoning office to confirm. source

Dwellings, tiny homes & RVs

Unclear - verifyThe county's zoning ordinance defines dwellings in a way that assumes utility connections, but I couldn't find a specific countywide rule on tiny homes or living in an RV full-time. Michigan follows the 2015 Residential Code statewide and hasn't adopted the tiny-home Appendix Q, so I'd confirm specifics with the county Building Department or Planning & Zoning.

Building permits & codes

RestrictedThe Otsego County Building Department enforces the 2015 Michigan Residential Code (plus 2015 mechanical/plumbing and 2017 fuel gas codes), and most new construction, additions, or use changes need a permit. Even a Temporary Certificate of Occupancy requires basics like heat, running water, a working bathroom, and smoke detectors, so building fully off-grid and unpermitted isn't a realistic path here. source

Septic & composting toilets

RestrictedSeptic systems in Otsego County are permitted and inspected by the Health Department of Northwest Michigan under the four-county District Sanitary Code, not by the county building department directly. Composting toilets as a septic substitute aren't addressed in anything I found, so that would need a direct call to HDNW. source

Greywater reuse

Generally allowedI didn't find any Otsego County or Health Department of Northwest Michigan rule specifically addressing greywater reuse, so this appears to fall back to the state plumbing code baseline administered by LARA. Worth confirming with the county Building Department if you're planning a specific greywater system. source

Rainwater harvesting

Generally allowedNo Otsego County ordinance specifically restricting or regulating rainwater harvesting turned up in my research, so it appears to be governed by the same statewide residential and plumbing codes the county has adopted. I'd still confirm with the Building Department before setting up anything tied into household plumbing. source

Private wells & water rights

RestrictedPrivate wells are permitted and inspected by the Health Department of Northwest Michigan under the District Sanitary Code, on top of the state's Water Well Construction and Pump Installation Code from EGLE. You'd apply for a well permit through HDNW, not the county building office.

Living disconnected from utilities

Unclear - verifyThere's no outright countywide ban on going off-grid for electricity that I found, but in practice the Building Department's occupancy standards (heat, running water, a working bathroom) and the requirement for a permitted well/septic system make full disconnection from water and sewage services hard to pull off legally. I'd call the Building Department directly to talk through a specific off-grid plan. source
