Unlock complete reportThe two-unit residential building at 5328 South Blackstone Avenue in Hyde Park, built in 1884 and currently owned by Gerald Grenon, has had limited documented activity over the past several years. The most recent and most frequent issues have been related to tree maintenance, with multiple requests for tree trimming and emergency services between 2025 and 2026, including an ongoing tree debris clean-up request as of June 2026. These tree-related incidents, while requiring municipal attention, do not directly impact the building's habitability. Additionally, in 2025, there was a water lead test kit request, which was properly closed out. Looking further back, the property had an asbestos-related complaint in 2017, though this was investigated and found to be an unfounded allegation. The building's documented service requests over the past seven years total eight, which is relatively low for an older residential structure, and no major structural or safety concerns have been reported during this period based on available data.

How 5328 S Blackstone 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 417 buildings in this neighborhood, 25 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
