Dearborn's Building Setbacks & Zoning: The Rules That Matter

Every city handles building setbacks & zoning a little differently. In Dearborn, Michigan, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Lot Coverage Limits

Dearborn caps a one-family home's footprint at 25% of lot area with a detached garage, or 30% with an attached garage, under the Zoning Ordinance's Section 29.02 Schedule of Regulations, regardless of lot size.

Key details: Max coverage, detached garage: 25% of lot area. Max coverage, attached garage: 30% of lot area. Governing provision: Zoning Ordinance § 29.02, footnote c. Permeable paver cap: 5% of landscaping area.

Exceeding the coverage cap or building without a permit is enforced as a Code of Ordinances § 1-9 general penalty violation: a fine up to $500 and up to 93 days, with each day counted as a separate offense.

Structure Height Limits

Dearborn ties a one-family home's height to its lot width: lots under 46 feet cap out at a 20-foot second-story eave, a 24-foot roof midpoint, and 2 stories, while lots over 180 feet reach 2.5 stories and a 31-foot roof midpoint.

Key details: Lot under 46' height cap: 2 stories, 24' midpoint. Lot over 180' height cap: 2.5 stories, 31' midpoint. Eave height range: 20 to 25 feet. Governing provision: Zoning Ordinance § 29.02, footnote a.

Exceeding the height table without a Zoning Board of Appeals variance blocks issuance of a building permit and is enforced as a Code of Ordinances § 1-9 general penalty violation, fined up to $500 with each day a separate offense.

Setback Rules

Dearborn's one-family districts require a flat 25-foot front yard, plus side and rear setbacks that slide with lot width: a 3-foot single side yard on a lot under 46 feet, growing to 18 feet on lots over 180 feet wide.

Key details: Front yard, all one-family lots: 25 feet. Side yard, lot under 46': 3 feet minimum. Side yard, lot over 180': 18 feet minimum. Rear yard range: 20 to 30 feet.

Building inside the required yard without a variance is enforced as a Code of Ordinances § 1-9 general penalty violation, a fine up to $500 and up to 93 days, and the Building Department will not issue a permit for a plan that violates the setback table.

The Bottom Line

Dearborn's building setbacks & zoning 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.
