Milwaukee, WI zoning map & districts

Milwaukee's zoning code is administered by the Department of City Development (DCD) and organized around a residential-family framework: Single-Family (RS), Two-Family (RT), and Multi-Family (RM) districts, each numbered by increasing density and decreasing lot size. Commercial land uses step up from Local Business (LB) districts serving neighborhood corridors to Regional Business (RB) districts along major arterials, while Light Industrial (IL1/IL2) and Heavy Industrial (IH) districts cover the city's manufacturing base, including the historic Menomonee Valley and Harbor District corridors.

A published summary is never the authority. The adopted ordinance and the city's official zoning map govern, and both change — verify the district and every standard on your parcel before you rely on it.

How zoning works in Milwaukee

A large share of active redevelopment — particularly along the Milwaukee and Menomonee Rivers and other former industrial riverfront parcels — proceeds through Planned Development (PD) approval, which lets DCD and the Common Council negotiate site-specific use, density, and design standards outside the numbered district's standard limits. Any project seeking a rezoning, PD, or variance goes through DCD's plan review and the City Plan Commission before reaching the Common Council for final approval.
