Unlock complete reportThe two-unit building at 1644 N Mozart St in Humboldt Park, owned by Tim Lindsay, has a documented history dating back to its 1888 construction. The property has faced persistent challenges in recent years, with four unresolved building code violations in the past seven years, three of which are related to complaint-driven inspections from September 2022 and March 2025. Moreover, there is one permit-related inspection violation from February 2020 that remains open. The building has generated eleven 311 service requests over the past seven years, with the most recent being a vacant lot complaint in May 2026. Notably, there has been a significant pattern of rodent-related issues, with four rat complaints between June and September 2024 alone, three of which were closed. Prior to the current issues, there was an illegal dumping incident in 2015 that was resolved. The combination of unresolved building violations and multiple rodent infestations suggests ongoing maintenance and environmental challenges at the property, though historical data beyond 2015 shows limited significant issues.
