Unlock complete reportThe two-unit residential building at 4140 South Campbell Avenue in Brighton Park, owned by Yun Chou Ni, has experienced a concerning pattern of issues in recent months. Most notably, on October 30, 2023, the property received multiple unresolved complaint-driven inspection violations, with six separate citations issued on the same date, all of which remain open as of the latest available data. This cluster of recent violations suggests ongoing maintenance or compliance challenges that could affect resident safety and comfort. The building's recent history also shows four 311 service requests between 2024 and 2025, all of which have been resolved, including matters related to tree emergencies, parking code enforcement, and garbage cart maintenance. While these previous issues were addressed, it's important to note that they represent the only recorded service requests for the past seven years, indicating either limited reporting or possibly underreported maintenance concerns. The property's documented history spans over 115 years since its construction in 1908, with no additional historical context provided in the current records.

How 4140 S Campbell Ave's risk score is calculated
We trained a model on 7 years of Chicago code enforcement data — building violations, 311 complaint history, environmental enforcement, and owner track records. It estimates the probability that the City of Chicago will find a code violation at this address in the next 12 months. Lower % = safer.
What the score means for you
Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Higher risk — riskier than most nearby
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 3962 buildings in this neighborhood, 3883 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
