Unlock complete reportThe three-unit residential building at 1123 W Patterson Ave in Wrigleyville, owned by Costello Prop An Illin, is a historic structure dating back to 1898. Over the past seven years, the building has recorded a total of three 311 service requests, with all three incidents occurring in May 2025. Notably, two of these requests involved animal-related issues - one for reporting an injured animal and another for requesting the pickup of a deceased animal - while the third was a general inquiry to 311 City Services. The relatively low number of service requests on record, particularly in recent years, suggests limited documented issues or concerns within the building or its immediate vicinity, though this should be considered in the context of potential underreporting of various building conditions or neighborhood incidents.

How 1123 W Patterson 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 404 buildings in this neighborhood, 158 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
