Unlock complete reportThe two-unit residential building at 3251 S Green Street in Bridgeport, owned by W Cheung Woon Koo, has been documented through the Chicago Master Building Record as having a consistent history of rodent-related issues over the past seven years. Built in 1893, this property has generated a total of six 311 service requests, with all being properly addressed and marked as closed. Notably, five of these requests between 2024 and 2026 were specifically related to rodent baiting and rat complaints, with the most recent incident occurring in March 2026 involving an animal in a trap. The frequency of these pest-related complaints, particularly concentrated between 2024 and 2026, suggests an ongoing challenge with rodent control in the vicinity of this property. While all reported issues were formally closed, the pattern of complaints over this extended period indicates that pest management has been a recurring concern for this address.

How 3251 S Green St'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
Grade A–B — Low risk
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 3117 buildings in this neighborhood, 2151 are predicted to be safer.
