Zoning Overlays & Bonuses in Dearborn, MI: What Residents Actually Need to Know

If you live in Dearborn or are thinking about moving there, zoning overlays & bonuses are one of those things you probably won't think about until they affect you directly. Dearborn has 2 specific rules on the books covering different aspects of zoning overlays & bonuses, and some of them might surprise you.

Density Bonus Law

In the mapped 'Bonus Height Area' of Dearborn's West Downtown District, Zoning Ordinance § 27.03(A)(4) lets developers earn extra stories above the district maximum by providing transit amenities, historic rehab, public art, or LEED-certified sustainable design.

Key details: Applies to: West Downtown 'Bonus Height Area' only. Story math: 2 points = 1 story. Top incentive: LEED Platinum earns 4 points. Cap: Capped at Ultimate Building Height. Decided by: City Planner or designee.

Claiming bonus height without meeting the City Planner's point determination gets the extra stories stripped from the site plan; a project reverts to the district's base maximum height until it re-qualifies.

If you are coming from a city with tighter rules, you will find Dearborn gives residents more flexibility on density bonus law.

Downtown Design Guide

Dearborn's West Downtown District follows Article 27.00, a form-based zoning code that sets build-to lines, height, architectural standards, and a 40-foot residential buffer, with Site Plan Review required for new construction and major expansions.

Key details: Governs: West Downtown District only. Residential-adjacent setback: 40 feet, no structures. Major projects: Full Planning Commission site-plan review. Minor changes: City Planner concept-plan review. Adopted: Ord. No. 19-1634 (2019).

Noncompliant plans are denied Site Plan Review approval by the City Planner, Planning Commission, or City Council; only the Zoning Board of Appeals can grant a variance from these build-to, height, and setback standards.

The Bottom Line

Dearborn's zoning overlays & bonuses rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Dearborn is broadly strict or permissive.
