Unlock complete reportThe two-unit residential building at 2311 S Kostner Ave in Chicago's North Lawndale neighborhood is a century-old property, constructed in 1907 and currently owned by Salomon Sanchez. Over the past seven years, the property has generated a total of three 311 service requests, all of which have been successfully resolved.

Prior to these, there was a parking code enforcement review request related to finance matters in November 2024, which also reached a closed status. While the building's service request record is relatively minimal, suggesting limited maintenance issues, it is worth noting that the most recent complaints have been clustered around street lighting concerns in the immediate vicinity of the property.

How 2311 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
