Unlock complete reportThe property at 9150 S Colfax Ave in Chicago's Calumet Heights neighborhood is a 1952 building currently owned by Artemio Patino, with a total of two parcels under ownership. The building's maintenance and safety record over the past seven years shows concerning patterns, particularly in the most recent year. As of September 2025, the building has five open and unresolved complaint-driven inspection violations, which is particularly significant given the total of nine building violations recorded in the past seven years. The most recent verified building issues appear to be related to plumbing, with two closed service requests in September 2025 specifically citing plumbing violations. Prior to these recent incidents, there was also a service request in September 2024 for a dead animal pick-up, which was subsequently closed. The building's violation and complaint history suggests ongoing maintenance challenges, warranting attention to the current open violations as the property continues to accumulate recent building code infractions.

How 9150 S Colfax 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

Out of 496 buildings in this neighborhood, 417 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
