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

Zoning & raw-land occupancy

Varies locallyArenac County has no countywide zoning ordinance; each township (Turner, Whitney, Deep River, Clayton, etc.) sets its own rules under the state Zoning Enabling Act, so you must check with the specific township. source

Dwellings, tiny homes & RVs

RestrictedTownships like Whitney explicitly exclude motor homes, trailers, and portable buildings from counting as a legal dwelling, and Deep River Township sets minimum floor area, foundation, and anchoring standards for manufactured homes. source

Building permits & codes

RestrictedThe Arenac County Building Department issues construction permits under the state's Single State Construction Code Act, but also requires a separate township zoning permit and proof of septic/well approval before issuing. source

Septic & composting toilets

RestrictedSeptic systems require a permit from the Central Michigan District Health Department, with site evaluation and a reserve drainfield area required; composting toilets as an alternative are not confirmed, and Deep River Township bans outhouses outright. source

Greywater reuse

Unclear - verifyNo Arenac County or CMDHD page specifically addresses greywater reuse; this likely falls back to the state plumbing code baseline, so confirm directly with the county building department.

Rainwater harvesting

Unclear - verifyNo county-specific rule on rainwater harvesting was found; it presumably follows the state plumbing code baseline set by Michigan LARA, but this is not confirmed locally.

Private wells & water rights

RestrictedWells require a permit from the Central Michigan District Health Department under the state Water Well Construction Code, and high-capacity wells (75 gpm or more) must also be registered through EGLE.

Living disconnected from utilities

Unclear - verifyNo explicit county ban on full utility disconnection was found, but township rules requiring approved water/sewer service plus building permit requirements for approved septic and well make off-grid living without those systems impractical in practice. source
