Unlock complete reportThe two-unit residential building at 8827 S Blackstone Ave in Calumet Heights, owned by Hubert Harris, has been standing since 1947 and has experienced relatively minimal issues over the past seven years. The property has one recorded building code violation from October 2024, which remains unresolved as of the latest available data. There have been three 311 service requests in this period, including a building violation report made in April 2024 (now closed), a tree emergency report from June 2025 (closed), and a general information call to 311 City Services in June 2025 (closed). While the number of violations and service requests is not excessive for a building of this age, the open status of the recent building code violation may warrant attention. The available records show no pattern of recurring problems or safety concerns, though the data only covers certain types of incidents and may not represent the complete conditions of the property.

How 8827 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 496 buildings in this neighborhood, 94 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
