Unlock complete reportThe six-unit residential building at 242 N Mason Ave in Chicago's Austin neighborhood, owned by James B Gussman, has experienced several notable incidents over the past seven years. Most concerning are two unresolved building code violations that were recorded on October 2, 2019, following a complaint-driven inspection. While the building's violation and service request history spans seven years, it is worth noting that all total and recent incident counts indicated in the report are for a 2025/2024 timeframe, which appears to be an error as these dates are in the future relative to the current date of October 2023.

How 242 N Mason 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 7223 buildings in this neighborhood, 6717 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
