Unlock complete reportThe three-unit residential building at 6255 W Diversey Avenue in the Belmont Cragin neighborhood was constructed in 1964 and is currently owned by Kazimierz Oleksy & Kry. The property's documented history over the past seven years shows a total of 11 service requests through the 311 system, with the most recent requests occurring in early 2026. A notable pattern emerges from the service requests, particularly during the latter half of 2025, when there were three separate complaints regarding missed garbage pick-ups between August 15 and October 8, 2025. In addition to the waste management issues, there was one complaint about an abandoned vehicle and a tree trim request within the same period. The frequency and clustering of garbage collection complaints over this relatively short timeframe may indicate some challenges with waste management services in the area during that period, though it's worth noting that the more recent tree trim request from February 2026 may have been resolved through proper channels, as this request type is no longer being accepted. While the service request history shows some operational issues, there are no recorded safety incidents or building code violations in the available data, and all documented service requests have been officially closed.

How 6255 W Diversey 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, 3162 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
