Ann Arbor Zoning Compliance for Sheds, Fences, and Decks Guide

Ann Arbor requires zoning compliance permits for several small residential projects that may not need a building permit, including small fences, detached decks, sheds, garages, carports, gazebos, greenhouses, and pergolas.

Permit takeaway

Ann Arbor lists detached carports, fences seven feet or less, floating or detached decks 200 square feet or less, detached garages 200 square feet or less, gazebos, greenhouses, pergolas, pool houses, and sheds 200 square feet or less as projects that may need zoning compliance permits even when a building permit is not required.

Zoning and placement

Zoning compliance review checks the proposed project against placement, use, and zoning ordinance rules before the work is built.

Building and trade review

A small-project zoning compliance permit is separate from a building permit decision, so a larger or more structural project can still need building review.

Call before applying when

Call before applying if the structure is near 200 square feet, the fence is near seven feet, the project is attached to the house, the property is historic, or the improvement changes use or occupancy.
