Unlock complete reportThe three-story multi-family building at 1900 S Throop in Chicago's Lower West Side has a documented history spanning over two decades, with the property dating back to 1870 and currently containing 12 units. The building's ownership is held by N Bonnin & M Giesso, who have maintained a single parcel ownership structure. The most pressing current concerns are four unresolved periodic routine inspection violations recorded in September 2025, which represent a potential pattern of compliance issues. In 2026, there have been several municipal service requests affecting the property and its surroundings, including an ongoing street light outage and a pothole complaint, though some issues have been resolved such as a tree emergency and fly dumping complaint. The building has a relatively clean record with only four building violations documented in the past seven years and no major structural or safety incidents reported. Historical complaints from the late 1990s included concerns about noise and air pollution, though these appear to be isolated incidents from over two decades ago with no recent patterns in similar complaints.
