Unlock complete reportThe two-unit residential building at 6221 N Claremont Ave in West Ridge, owned by Nicolas Zumba, has experienced significant regulatory activity in recent years. Built in 1924, this property has accumulated a total of 18 building code violations over the past seven years, with the majority of these (seven violations) concentrated in 2025-2026. All of these recent complaints remain unresolved and were categorized as complaint-driven inspections, indicating potential ongoing concerns about the building's condition or compliance with regulations. The property has also generated three 311 service requests in the past seven years, all of which have been properly closed and were unrelated to the building's structural or safety issues—these included complaints about an abandoned vehicle (July 2025), an open fire hydrant (June 2025), and a parking code enforcement review (April 2025). An earlier environmental complaint from January 2002 regarding air pollution is the only historical complaint on record, though this predates the current ownership period by several years. The concentration of recent unresolved violations suggests that the building may be facing continuing compliance challenges that merit attention.
