Kent County does not zone land. Whether you may build an accessory dwelling unit (ADU) is set by your city, village, or township under the Michigan Zoning Enabling Act. Check your local zoning ordinance and planning department, not the county.

A local unit of government may provide by zoning ordinance for the regulation of land development and the establishment of 1 or more districts within its zoning jurisdiction which regulate the use of land and structures...
Sheds are governed by your city or township zoning ordinance, not Kent County. Rules on size, number, setbacks, and permits vary. For example, Kentwood allows up to two accessory buildings per lot and requires a building permit above 120 square feet.
