Unlock complete reportThe two-unit residential building at 4635 S Mozart St in Brighton Park is a 1914 property currently owned by Maria Mejia. The building's documented history shows minimal recent activity over the past seven years, with only three service requests recorded through the city's 311 system. All three of these recent requests, noted in November 2025, pertained to vehicle parking violations, including two city vehicle sticker violations and one parking code enforcement review, all of which have been closed. A more dated incident from 2000 is on record regarding illegal dumping, which resulted in a work order, though this environmental complaint is significantly less relevant given its age and the fact that more than two decades have passed since the occurrence.
How 4635 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, 1701 are predicted to be safer.
