A five-story cream-brick hospital building that has watched over Milwaukee's East Side for more than a century could soon be filled with tenants instead of patients. Under preliminary plans, the historic former St. Mary's Hospital may be converted into affordable apartments, according to conceptual proposals associated with Ascension Wisconsin.
The early-stage housing concept concerns the former hospital. The Historic Water Tower Neighborhood Association, established in 1973, represents an area containing Wisconsin's largest concentration of historic homes, stretching along Lake Michigan from East Edgewood Avenue to East Lafayette Place, according to the Historic Water Tower Neighborhood group's own account of its boundaries.
A Landmark Building With Deep Roots
The building at the center of the proposal is located at 2320–2388 N. Lake Drive, per records from the Milwaukee Public Library. The hospital's roots stretch back even further: it traces its origin to St. John's Infirmary, founded by the Daughters of Charity on May 15, 1848, the same year Wisconsin achieved statehood, making it the state's first public hospital, according to the Historical Marker Database. That original infirmary operated near Jackson and Wells Streets in downtown Milwaukee before the institution moved east.
The institution's earlier history predates the current Lake Drive site. The building's historic-designation status and any approval requirements for exterior alterations tied to a residential conversion are not established in the available account.
Recent Structural Work Preceded the Housing Pitch
The push toward reuse reflects the possibility of giving the former hospital building a new use outside its earlier role.
Just months before this week's neighborhood presentation, Ascension Columbia St. Mary's sought a Certificate of Appropriateness from the Milwaukee Historic Preservation Commission in December 2025 to remove an elevator shaft at the historic building, according to city meeting records. The filing predates the broader redevelopment conversation now underway.
A Cautionary Precedent Nearby
Milwaukee's East Side has already seen one hospital-to-housing conversion effort stumble. A former Columbia St. Mary's hospital building on the University of Wisconsin-Milwaukee campus near North Maryland Avenue and East Hartford Avenue was slated for demolition beginning in September 2021, not 2020, after student-residence reuse was rejected, as detailed by Urban Milwaukee. Earlier studies of that site found neighborhood opposition or incompatibility, even as they identified student residence use as the most compatible and economical option.
Still, the discussion concerns the former institutional building. Affordable housing is among the potential uses described in the proposal.
The preliminary plan leaves open questions about how Ascension's plan would be financed, how many units it might ultimately yield, and what income thresholds would apply to tenants. The timeline for any formal submission to city zoning boards has also not been announced.
