Detroit Zoning System
The Detroit zoning system includes 24 total zone classifications: 6 residential zones (R1, R2, R3, R4, R5, and others) and 5 commercial zones (B1, B2, B3, B4, and others), as well as 3 mixed-use zones (SD1, SD2, SD4) and 5 industrial zones (M1, M2, M3). Detroit's zoning is governed by the Detroit City Code, Chapter 61 (Zoning), last comprehensively updated as part of the Detroit Master Plan of Policies. Unlike Sun Belt growth cities, Detroit is the nation's largest shrinking city by population — it lost over one million residents since 1950, leaving approximately 25% of its land area as vacant lots. This vacancy crisis has created a unique urban context where ADUs and infill development take on special significance: the city actively uses its Detroit Land Bank Authority (DLBA) to sell vacant parcels for redevelopment. Residential zones are designated R1 through R6, with R1 being the lowest-density single-family and R6 allowing higher-density multifamily. Detroit's housing stock is dominated by early 20th century working-class homes, and the city has made encouraging infill and ADU construction a part of its housing revitalization strategy. The city maintains an interactive zoning map for property lookup.

Can I build an ADU on a vacant lot I bought from the Detroit Land Bank?
Yes, but it requires careful steps. Detroit Land Bank Authority (DLBA) properties purchased for side lot or development use may be subject to deed restrictions requiring improvement within a set timeline. To build a standalone ADU on an adjacent vacant lot, you would typically first consolidate the lots through the City of Detroit, then apply for a BSEED building permit for the ADU. Contact the Detroit Planning and Development Department to confirm consolidation requirements before purchasing.
What makes Detroit's ADU situation unique compared to growing cities?
Detroit is the nation's largest shrinking city, with roughly 25% of its land area now vacant. This means ADU opportunities in Detroit are different from cities like Austin or Denver. Rather than adding to congested neighborhoods, Detroit ADUs often serve as infill on empty lots, help rehabilitate underused carriage houses and garages, and contribute to the city's comeback strategy. The Detroit Land Bank Authority sells vacant lots at low prices specifically to encourage this kind of development.
Are short-term rentals (Airbnb) allowed in Detroit?
Yes. Detroit allows short-term rentals and requires an STR license ($100/year). Michigan Act 20 of 2023 prevents Detroit from banning STRs outright in residential zones, though Detroit may impose operational requirements. STR operators must have a Certificate of Occupancy and comply with Detroit's rental housing standards. Detroit's urban revival has made Corktown, Midtown, and the Riverfront attractive for Airbnb visitors.
I own a home in the Boston-Edison Historic District. Can I make exterior changes?
Yes, but you need a Certificate of Appropriateness from the Detroit Historic District Commission (HDC) before beginning any exterior alterations, including additions, siding changes, window replacements, or ADU construction visible from the street. The HDC reviews proposals for compatibility with the district's historic character. Applications are reviewed at monthly HDC meetings. Contact the Detroit Planning and Development Department at (313) 224-6380.
What permits does Detroit require for a home addition?
A building permit from the Detroit BSEED is required for all structural additions. You'll need architectural drawings, property ownership verification, and compliance with zoning setbacks. Permit fees are based on construction value. Detroit's permit office is at the Coleman A. Young Municipal Center. Applications can be initiated online through the BSEED portal. Expect 4-8 weeks for plan review.
