Great Lakes Tiny Homes Zoning Intelligence-Volume 4: Vergennes Township, Kent County “Accessory Dwelling Unit (ADU)” Zoning Ordinance Provision
Through the recent number of inquires, I have decided to focus my tiny house zoning research on the western area of lower Michigan. Today I discovered some exciting news about a community near Grand Rapids, MI. Vergennes Township is located in Michigan’s western Lower Peninsula in the west side of Kent County.
Although this provision calls for the minimum floor area of the ADU to be 400 sq/ft, this is very promising for the tiny house movement in Michigan! I am confident that with the appropriate advocacy efforts, that ordinances similar to this one could become commonplace throughout the United States. I hope you find this information useful!
The Vergennes Township definition of an accessory dwelling unit (ADU) is listed below:
“Accessory Dwelling: A dwelling unit consisting of either a stick built house, mobile home, converted out-building or other habitable space/structure used in conjunction with the main dwelling for the housing of non-paying visitors, guests or family, separate from the primary dwelling containing separate kitchen, sleeping and bathroom facilities, and not exceed the size of the main floor of the primary dwelling unit.”
Below is a link to the Vergennes Township zoning ordinance. I have also included the excerpt from page 146 where the accessory dwelling unit (ADU) provision is contained.

The property owner is responsible for recording the SEUP.
16. The application for such special exception use permit shall be made in accordance with section 201.502 of this ordinance."
