Unlock complete reportThe two-unit building at 1631 N Sawyer Ave in Humboldt Park, owned by Austin S Ng, has a documented history dating back to its 1895 construction. The property currently faces multiple outstanding issues, with three open building code violations resulting from complaint-driven inspections in both 2024 and 2022, which notably includes a recent building violation complaint from May 2026. The building's maintenance and resident experience have been a concern, as evidenced by a total of 19 service requests filed by the owner over the past seven years. While there have been some resolved service requests, including yard waste pick-up and tree-related matters, there is a concerning pattern of rodent-related issues, with two baiting/complaint requests recorded in 2024 and 2025. The property's historical record maintains only one building permit in the past seven years, suggesting limited permitted work has been conducted during this period. While some service requests have been appropriately addressed, the persistence of open violations and the frequency of pest-related complaints warrant attention to the building's current condition and management practices.

Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
