Unlock complete reportThe two-unit residential building at 11930 S Union Ave in West Pullman, owned by Pettis Porter, has a documented history dating back to its construction in 1908. The property has experienced significant unresolved building code violations, with six open violations resulting from a February 26, 2020 complaint-driven inspection that have remained outstanding for several years. While the building has maintained a relatively low number of service requests to the city's 311 system over the past seven years, there have been two recorded incidents: a closed fly dumping complaint in September 2025, and a July 2024 information-only call. The persistent nature of the building code violations is particularly notable, as they represent a cluster of unresolved issues that have been outstanding for approximately 3.5 years since their initial documentation.

How 11930 S Union 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 1015 buildings in this neighborhood, 782 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
