The upper floor of a Milwaukee historic Downer Avenue Commercial District building to be converted into 13 housing units

Thirteen multifamily units are planned for the second floor of the middle portion of the building at 2551-2597 N. Downer Ave., according to a building permit application filed with the city Department of Neighborhood Services.

The housing units — the permit application doesn't specify if they are apartments or condos — would total around 9,500 square feet.
