Michigan Tiny House Zoning Laws Overview
Michigan’s land‑use framework centers on the **Michigan Zoning Enabling Act (PA 110 of 2006)**, which empowers cities, townships, villages, and counties to adopt and enforce zoning ordinances. The **Bureau of Construction Codes (LARA)** administers state building codes and adoptions, while local governments implement those codes through plan review and inspection. There is no statewide ADU mandate; eligibility for small dwellings on permanent foundations depends on local ordinances and district standards. By contrast, tiny houses on wheels (THOWs) are generally treated as trailers under the **Michigan Vehicle Code**, meaning long‑term residential use requires explicit local allowance or siting in a licensed/regulated community. The practical workflow is to determine whether your site is regulated by a municipality or only the county, review the applicable ordinance for ADU or small‑dwelling provisions, and coordinate with Building/Inspections on utilities, access, stormwater, and life‑safety under the current Michigan code cycle.
Michigan has no statewide ADU mandate; THOWs are typically treated as trailers unless a local ordinance allows dwelling use.
