Unlock complete reportThe six-unit residential building at 3107 N Harding Ave in Avondale, owned by Jan Rozycki, has a documented history dating back to its construction in 1926. The property is currently showing concerning activity, with four unresolved complaint-driven inspection violations reported on November 20, 2024. Historically, the building has accumulated a total of seven building violations over the past seven years, along with thirteen 311 service requests and two building permits. The most recent service requests indicate some ongoing community and maintenance issues, including two unresponsive sidewalk snow clearance complaints in early 2026, and multiple sanitation code violations in 2025, though these were subsequently closed. There is also an open tree planting request from August 2025 and a closed dead animal pick-up request from October 2025. While the building has experienced various code violations and service requests over the years, particularly regarding sanitation and snow clearance, the most pressing current concern appears to be the recent unresolved inspection violations from November 2024.

How 3107 N Harding Ave's risk score is calculated
