Unlock complete reportThe two-unit residential building at 9930 South Avenue J in Chicago's East Side neighborhood, owned by Hector M Gonzalez, has been standing since 1890 and has generated a total of 14 service requests through the 311 system over the past seven years. The most recent service activity includes three requests in 2026: two sidewalk inspection requests from late April and late May (both currently open), and a yard waste pick-up request from June that has since been closed. The property has experienced recurring issues with alley infrastructure, as evidenced by two separate pothole complaints in September 2025, both of which have been resolved. Prior to 2025, there was one informational call to 311 in November 2025 that was closed, though the nature of this call is not specified in the records. The open sidewalk inspection requests from 2026 warrant attention, as they may relate to pedestrian safety and accessibility.

How 9930 S Avenue J 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 953 buildings in this neighborhood, 95 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
