Unlock complete reportThe three-unit building located at 9924 South Exchange Avenue in South Deering is a 1921 construction currently owned by Sergio Castro. Over the past seven years, the property has generated a total of 10 service requests through the 311 system, with a notable concentration on garbage cart maintenance issues, accounting for seven out of the ten total requests. Most recently, there have been multiple garbage cart maintenance requests in September 2025, along with others in November 2024. Additionally, there were two tree debris clean-up requests in August 2024. The building has experienced one environmental complaint in recent years, filed in April 2026 regarding air pollution, though this issue was promptly resolved on the same day it was reported. While the property's service request history shows recurring waste management concerns, particularly with garbage cart maintenance, it's worth noting that all reported issues have been officially closed, including both clean-up requests and the environmental complaint.

How 9924 S Exchange Ave 1'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 376 buildings in this neighborhood, 53 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
