ADU rules in Warren, MI — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Warren does not have a general ADU ordinance. Accessory dwelling units are not permitted by right in Warren. The city's zoning documents address only small accessory structures (sheds, garages) with no reference to secondary dwelling units.
Michigan does not have a statewide ADU mandate. ADU permissibility depends entirely on Warren zoning code. Some Michigan cities (Ann Arbor, Grand Rapids, Detroit) have adopted ADU-friendly zoning allowing accessory dwelling units on residential lots. Others prohibit additional dwelling units in single-family zones. Where allowed, ADUs typically must meet size limits (600 to 800 sq ft), setback requirements, and may have owner-occupancy rules. A building permit is required. Parking requirements may apply.
Unpermitted ADU: standard building code enforcement. Zoning violation: cease-and-desist + fines. Must bring to code or remove.
