Unlock complete reportLocated in Bridgeport, 3211 S Union Ave is a 4-unit residential building constructed in 1888 and currently owned by Ann M Jarosz. The property's recent record (2016-2023) shows some concerning patterns, particularly in early 2026, when there were multiple service requests including two no water complaints, a missed garbage pick-up, and two abandoned vehicle complaints, all of which were closed. The building's environmental enforcement history from 2020 reveals two notable violations related to construction site cleanliness, with one resulting in a $500 fine regarding chain link fence issues, while the second violation concerning fabric mesh was dismissed with no fine imposed. There's a single building code violation on record from December 2021 related to permit inspections, though this was resolved. While the total counts of violations and service requests over the past seven years are relatively low (1 building violation, 12 service requests, and 2 environmental enforcement cases), the concentration of issues in early 2026 and the recent water-related complaints may be of particular note for potential residents.

How 3211 S Union 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.

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

Out of 3132 buildings in this neighborhood, 2286 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
