Unlock complete reportThe two-unit residential building at 3912 N Harlem Ave in Chicago's Dunning neighborhood, owned by John Pizzoferrato and constructed in 1925, has experienced several notable events over its history, with particular attention needed on recent issues. Most concerning are two unresolved complaint-driven building code violations recorded in June 2024, which remain open as of the latest available data. The building has generated multiple service requests in 2026, with the most recent activities focusing on waste management, including three requests for blue recycling cart services and one for garbage cart maintenance, all of which have been resolved. Of particular note is a cluster of leak-related service requests between February and March 2026, with three such requests requiring attention, including one involving the Department of Water Management, all of which were subsequently closed. The property's historical record also shows two environmental complaints related to toxic hazardous materials, dating back to September 1993 and September 2006, though it's unclear what, if any, resolution was reached regarding these issues. With no recorded violations or service requests between 2019 and 2023, it appears there was a period of relative stability before the recent uptick in service requests and unresolved violations.
