Off-Grid Living in Antrim County, Michigan

Antrim County, Michigan is a genuinely mixed bag for off-grid living, and the biggest thing I want you to understand up front is that the county itself has no county-wide zoning ordinance. Zoning authority sits with the townships and villages. Eight townships and five villages have their own zoning ordinances and administrators; the rest have no zoning at all. That means the very first question, "can I put a tiny house / RV / off-grid cabin on this parcel," has no single Antrim County answer. You have to find out which township your land is in and call that township's zoning administrator, per the county's own planning department page.

Where the county does have uniform authority is building permits. The Antrim County Construction Code Department requires permits for building, plumbing, electrical, and mechanical work on any new construction, addition, alteration, or change of occupancy, and enforces the Michigan Residential Code (a state-level code applied locally) along with locally-specific snow load and wind speed design criteria. New homes also need a blower door test before a certificate of occupancy is issued.

Septic and wells are handled by a district health authority, not the county alone: the Health Department of Northwest Michigan (HDNW) administers a District Sanitary Code covering Antrim, Charlevoix, Emmet, and Otsego counties. You need a permit before installing, altering, or extending a sewage system, and the same permit requirement applies to private wells. HDNW works with property owners on site evaluation before issuing septic permits.

Greywater and rainwater harvesting are honestly a gap in the public record I researched. I could not find an Antrim-specific ordinance on either topic, at county or district level, so I'm treating both as not confirmed, likely falling back to the state Plumbing/Residential Code baseline, but you should ask the Construction Code Department directly before you build a greywater or catchment system.

As for going fully off-grid, disconnected from municipal water and sewer, there's no outright county ban that I found, but there are real practical checkpoints. Some townships, like Milton Township, run point-of-sale or time-of-transfer septic and well inspection ordinances. And HDNW's own home buying/building guide asks explicitly whether a home will need a new well or septic system, which tells me an approved water and waste system is basically baked into the approval process, even if "off-grid" isn't the literal language used.

Bottom line: treat this as a two-layer puzzle. County/district layer (building permits, septic, wells) is strict and uniform. Township layer (zoning, RV/tiny home occupancy, camping duration limits) is a patchwork you must check parcel by parcel.
