Detroit Zoning & Permits

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). STR operators must have a Certificate of Occupancy and comply with Detroit's rental housing standards. Note: No enacted Michigan state law preempting local STR bans has been identified — Michigan PA 20 of 2023 is a sales-tax act unrelated to STR regulation. Detroit may impose STR regulations including operational requirements.

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 for more information.

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.
