Detroit Building Permit Exempt Work Guide

Detroit lists several building-permit exemptions, but homeowners still need to check zoning, right-of-way, trade, and special-condition requirements.

Permit takeaway

Detroit says building permits are not required for certain small detached accessory structures, fences not more than seven feet high, low retaining walls, and some sidewalks or driveways.

Zoning and placement

Permit-exempt work can still be affected by zoning, easements, historic districts, right-of-way, and other city requirements.

Building and trade review

Detached accessory structures are exempt only when one story and no more than 120 square feet, while retaining-wall exemptions do not apply when surcharge or certain liquids are involved.

Call before applying when

Call before starting if the shed is near 120 square feet, the fence is near seven feet, the retaining wall supports soil or a driveway, or the work touches the right-of-way.

• Height above grade
• Surcharge, easement, or right-of-way details if relevant
