Michigan's housing stock includes many older homes. These often have basements, garages, or yards that can be converted into ADUs. The harsh winter weather is a major factor. Building during the spring, summer, or fall is generally more efficient. Snow and freezing temperatures can halt construction. Permitting rules for ADUs vary across Michigan. Detroit has specific zoning for these units. We help you navigate these local requirements.
