Where can I build my tiny house in Michigan?

Here is one of the most important questions you’ll need to answer regarding your tiny house: where you will put it. In Michigan, the answer to this question will depend on local laws, which vary by city or county. Municipal and county zoning codes will decide on the locations you are permitted to build a tiny house at. 
You will most likely need a permit to begin building an ADU. Depending on local standards, you may be able to build a tiny house in your backyard (or a friend’s) or join a tiny house community like the one in Traverse City. If you decide on an Economy Efficient Dwelling, you’ll need to follow Briley Township’s guidelines.
