Unlock complete reportThe two-unit residential property at 6521 W Belmont Ave in the Belmont Cragin neighborhood, built in 1952 and owned by Zdzislaw Sobolewski, has had limited documented issues over the past seven years, with a total of four 311 service requests. All recorded complaints have been resolved. The most recent incident, from May 2026, involved a water-on-street complaint, while December 2025 saw a complaint regarding uncleared snow on the sidewalk, which could impact pedestrian safety during winter months. Two service requests were made simultaneously on September 25, 2025, concerning garbage and blue recycling cart maintenance, suggesting some attention was needed to waste management services. While the frequency of complaints is relatively low for a two-unit building, the past year has shown an unusual cluster of service requests in September 2025, though all issues appear to have been addressed promptly through the appropriate channels.

How 6521 W Belmont 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
Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Higher risk — riskier than most nearby
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 4453 buildings in this neighborhood, 2494 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
