This page aims to clarify current state and local requirements for operating a rental property in the city of Detroit. Rental housing registration and certification laws and ordinances exist to help Michigan cities identify and regulate rental units to ensure safer and better quality housing for tenants and the surrounding community. Under the Michigan Housing Law (MCL 125.401, et seq.), cities are authorized to regulate multi-family rental housing, including requiring that a Certificate of Compliance be obtained prior to occupancy of a rental unit. Detroit also adopted a local ordinance to regulate one- and two-family rental properties, which account for a large supply of rental units across the city.
