Read this before you act on anything below. This is my researched starting point for Antrim 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 rulesAntrim County, MI

Zoning & raw-land occupancy

Varies locallyAntrim County has no county-wide zoning ordinance; zoning authority rests with eight zoned townships and five villages, each with its own administrator, while unzoned townships have no local zoning at all. You must identify your specific township first. source

Dwellings, tiny homes & RVs

Varies locallyRV camping, temporary dwelling, and tiny-home occupancy rules are set township by township; one township draft ordinance limits RV storage and camping duration, but this is not a countywide rule and each township must be checked individually.

Building permits & codes

RestrictedThe Antrim County Construction Code Department requires permits for building, plumbing, electrical, and mechanical work countywide, and enforces the Michigan Residential Code 2015 with local snow load and wind speed criteria; new homes need a blower door test before occupancy. source

Septic & composting toilets

RestrictedSeptic systems are regulated by the Health Department of Northwest Michigan under the 2017 District Sanitary Code covering Antrim, Charlevoix, Emmet, and Otsego counties; a permit is required before construction, repair, alteration, or extension of any system. source

Greywater reuse

Unclear - verifyNo Antrim County or district-specific greywater rule was found; this presumably falls under the state Plumbing/Residential Code baseline, but you should confirm directly with the Construction Code Department.

Rainwater harvesting

Unclear - verifyNo Antrim-specific rainwater harvesting rule was found beyond the presumed state Plumbing Code baseline; not confirmed at county or district level.

Private wells & water rights

RestrictedPrivate wells require a permit through the Health Department of Northwest Michigan under the same 2017 District Sanitary Code that governs septic systems, and some areas may have a 'well first' policy. source

Living disconnected from utilities

Unclear - verifyNo blanket county ban on disconnecting from utilities was found, but some townships (like Milton Township) run point-of-sale septic/well inspections, and the health department's buyer guide expects an approved water/waste system as part of occupancy. source
