Unlock complete reportThe property at 9135 S Western Ave in the Beverly neighborhood is a four-unit residential building constructed in 1960, currently owned by Brian Oneill. The building's documented history over the past seven years shows a relatively low frequency of service requests, with a total of seven 311 reports filed. The most recent two incidents, recorded in April and March 2026, were related to street maintenance issues (potholes), while three abandoned vehicle complaints were logged in August 2025, with one reported to the Alderman's office and two through 311 City Services. Prior to these incidents, there was one request for dead animal removal in September 2024. The nature of these complaints suggests that most issues have been related to external factors rather than building-specific problems, with all reported incidents having been successfully resolved according to their "Closed" status.

How 9135 S Western 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 300 buildings in this neighborhood, 207 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
