Unlock complete reportThe four-unit residential building at 3603 S Winchester Ave in McKinley Park, owned by SZHANG, has a relatively sparse service record since its construction in 1894. The property has had only three documented 311 service requests over the past seven years, all of which were tree trim requests submitted on April 21, 2025. These requests, while closed, were for a service type that is no longer being accepted through the 311 system. The limited number of service requests on record, particularly for a structure of its age and size, may suggest either proactive maintenance by the current ownership or underreporting of issues, though no definitive conclusions can be drawn from the available data alone.

How 3603 S Winchester 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.
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 1407 buildings in this neighborhood, 971 are predicted to be safer.
