Detroit Residential Deck Permit Guide

Detroit residential deck permits require plot plans, foundation depth, framing details, guardrail and stair information, and zoning setback checks.

Permit takeaway

Detroit's residential deck requirements call for a building permit application for additions, alterations, or repairs.

Zoning and placement

Detroit deck placement must respect rear-yard, front-yard, side-yard, easement, and corner-lot setback limits.

Building and trade review

Detroit deck plans should show 42-inch minimum foundation depth, joist spacing, beam spans, column sizes, deck height, guardrails, balusters, stairs, and subdivision approval when relevant.

Call before applying if the deck projects into a setback, is on a corner lot, crosses an easement, is more than 30 inches above grade, or needs subdivision approval.
