Minneapolis has long been renowned for its handsome, livable neighborhoods. For more than a century, its housing has primarily been low-density—mostly single-family though also many duplexes, which were typically located near streetcar lines. Of course Minneapolis has always had some multi-family housing. This includes workingman's flats built near industrial areas, prewar apartments located around busy centers like Uptown, and a scattering of postwar high-rise housing intended for senior citizens and empty nesters. The housing boom for the better part of the 2000's has created a sharp influx in both new construction Minneapolis condos and lofts as well as conversions from office space, abandoned warehouses and apartment buildings into lofts and condos.
