Unlock complete reportThe two-unit residential building at 4627 S Mozart St in Brighton Park, owned by Aun Kok Chen, was constructed in 1925 and has had relatively few service requests in recent years. Over the past seven years, there have been five recorded 311 service requests associated with the property. The most recent request, submitted in May 2026, is currently open and pertains to tree removal inspection. Prior to this, the property experienced two parking-related incidents in late 2025, including a Finance Parking Code Enforcement Review in December and another similar review in June of the same year, both of which were resolved. Additional service requests include a snow removal-related complaint in December 2025, which has since been closed, and a general information call to 311 in October 2024, which also resulted in no follow-up action. The building's service request history shows no pattern of recurrent issues, though the open tree removal inspection request represents the most significant ongoing matter at this time.
How 4627 S Mozart 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 3956 buildings in this neighborhood, 1108 are predicted to be safer.
