Deck Construction Permits in Milwaukee
Local Rule
City of Milwaukee Department of Neighborhood Services / Building Inspection Division
Wisconsin carries no statewide small-deck exemption, and the city's own document confirms plans must be submitted for any new or replacement deck. Milwaukee runs two permit tiers rather than exempting small decks outright: a simpler Residential Deck Permit applies to a deck under 200 square feet and under 30 inches above grade, while a full Building Permit applies to anything larger or taller, so a permit of one type or the other is effectively always required. The process starts with a zoning permit from the Department of Neighborhood Services, followed by plan review from the Building Inspection Division at 809 N. Broadway; footings must reach 42 inches, the deck must sit at least 3 feet from property lines, and a property in a historic district needs a Certificate of Appropriateness from the Historic Preservation Commission.
