Detroit Zoning & Land Use Guide
Key Zoning Facts
Detroit Zoning Overview
Detroit's zoning ordinance is one of the most extensively revised in the Midwest, reflecting the city's ongoing transformation from a manufacturing powerhouse to a diversified economy focused on technology, healthcare, and urban revitalization. The Planning and Development Department administers the zoning code, which organizes the city into residential, business, industrial, and special-purpose districts across its 139 square miles.
The city has adopted significant zoning reforms in recent years, including updates to support mixed-use development, streamline the permitting process, and address the city's vast inventory of vacant land. Detroit's Strategic Neighborhood Fund and neighborhood planning initiatives have produced area-specific zoning recommendations that guide development in targeted neighborhoods.
Detroit's unique challenges, including large amounts of vacant land and a legacy of industrial contamination, have led to innovative zoning approaches such as urban agriculture districts and special development zones that allow flexible uses on formerly industrial sites.
Key Zoning Districts
Detroit uses a numbered system with R1 through R6 residential districts (increasing density), B1 through B6 business districts (local to intensive commercial), and M1 through M5 industrial districts. Special-purpose zones include SD (Special Development), PD (Planned Development), and PC (Public Center).
ADU Regulations
Detroit allows accessory dwelling units in residential districts under its local zoning ordinance, as Michigan has no statewide ADU law. ADUs are limited to 800 square feet and 18 feet in height, with one parking space required. Owner-occupancy of either the primary or accessory unit is required. The Buildings, Safety Engineering, and Environmental Department processes ADU permits.
Development Process
Development in Detroit starts with a zoning review through the Planning and Development Department. Conforming projects proceed to the Buildings, Safety Engineering, and Environmental Department for permits. Projects requiring relief apply to the Board of Zoning Appeals. Large projects may require Planning Commission site plan review.
