Unlock complete reportThe two-unit building at 350 S Kostner Ave in Garfield Park, owned by Sarah Swilley, has been in operation since 1903 and has experienced a notable pattern of issues over recent years. Most concerning are the seven unresolved complaint-driven inspection violations recorded on November 3, 2022, which remain open as of the latest records. These violations, while not specifying their nature in the available data, suggest significant ongoing compliance issues that have not been addressed. The building's 311 service request history shows 15 documented incidents in the past seven years, with the most recent activity in 2026. These requests primarily relate to neighborhood maintenance issues rather than building-specific problems, including multiple reports of fly dumping, an alley pothole, and garbage cart maintenance needs. The only building permit recorded in this period was issued in 2020, suggesting limited recent investment in property improvements. While the 311 service requests indicate ongoing neighborhood maintenance concerns, it's important to note that these are primarily related to external rather than internal building conditions.

How 350 S Kostner 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 3998 buildings in this neighborhood, 3798 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
