Unlock complete reportThe two-unit residential building at 3023 S Union Ave in Chicago's Bridgeport neighborhood is a century-old property constructed in 1900, currently owned by Xiaoning Li. Over the past seven years, there have been seven documented 311 service requests associated with this address. The most recent request, filed in June 2026, pertains to a water lead test kit, which remains open as of the latest data. The building's service history shows relatively minimal municipal interaction, with most issues being routine in nature. Between 2024 and 2025, there were two tree trimming requests (both of which are no longer being accepted), one garbage cart maintenance request, and one pothole complaint in the street near the property. A 311 information-only call was also logged in December 2025. While the property has had occasional maintenance and service requests, there are no recorded incidents of serious safety concerns or resident experience issues, though the open water lead test kit request warrants attention as the most recent service interaction.

How 3023 S Union Ave 1'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 3132 buildings in this neighborhood, 595 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
