West Allis City Hall is located at 7525 W. Greenfield Ave.
The announcement came by way of a certificate shared in a City of West Allis, WI Government Facebook post, which states that the committee designates West Allis City Hall a Milwaukee County Historic Landmark for its historic significance, presented on the 9th day of November 2026. The certificate bears the signatures of Kathy Nusslock, the Landmarks Committee chairperson, and Benjamin Barbera, the committee's executive director. According to the city's post, the designation recognizes the building's architectural significance and its connection to West Allis history, and officials describe it as an important example of modernist architecture in Milwaukee County.
West Allis City Hall
City Hall's story stretches back nearly six decades. According to the Wisconsin Historical Society, construction broke ground on Oct. 21, 1967, replacing the city's former city hall, which dated to 1921. Main offices were occupied by early 1969, and the council chamber followed a year later, with the building formally dedicated on May 3, 1970.
The building was constructed by the Joseph P. Jansen Company of Milwaukee. OnMilwaukee has reported the completed building at 41,400 square feet.
Joining a Short List of County Landmarks
The designation places West Allis City Hall alongside other sites recognized by Milwaukee County for their historic and cultural value. The Milwaukee County Historical Society's landmarks page, for instance, lists the Mitchell Park Horticultural Conservatory — better known as the Domes — among the county's designated landmarks, giving a sense of the company City Hall now keeps.
Under Wisconsin law, counties hold broad authority tied to such designations. State statute 59.69(4h)(c), published by the Wisconsin Legislature, allows a county, as an exercise of its zoning and police powers for promoting the health, safety and general welfare of the community and the state, to regulate by ordinance.
West Allis City Hall remains in use as the city's seat of local government.
