Initial analysis

The six-unit residential building at 4657 N Winthrop Ave in Chicago's Uptown neighborhood, owned by Stefan J Madjar, has a relatively low number of documented service requests over the past seven years, with only three incidents recorded through the 311 system. The property, constructed in 1903, experienced two tree-related service requests in May and July of 2024, though it's worth noting that such requests are no longer being accepted through the 311 system. More recently, in April 2026, there was a documented incident of graffiti requiring removal, which has since been closed. While the overall number of service requests is limited, it's important to consider that the nature of these requests (primarily regarding tree maintenance and exterior graffiti) generally relates to building surroundings rather than internal living conditions, and all recorded issues have been officially closed.

Risk rating

How 4657 N Winthrop 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.
