Unlock complete reportThe two-unit building at 8641 S Houston Ave in South Chicago, owned by Miguel Contreras, is a century-old structure built in 1910. The property has experienced a notable number of regulatory interactions over the past seven years, with a total of 14 building violations recorded, though all these violations appear to be related to a single series of complaint-driven inspections conducted on January 6, 2023, which have since been resolved. Interestingly, while the building has two recorded 311 service requests, only one of these - a tree emergency - was documented in July 2025 and appears to have been addressed through the Alderman's office. The consistent pattern of complaint-driven inspections in early 2023 suggests there may have been significant tenant concerns at that time, though it's worth noting that all identified issues were successfully resolved. The building's record shows no further documented violations or complaints since these incidents, marking a period of apparent regulatory compliance.

How 8641 S Houston Ave 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

Out of 2611 buildings in this neighborhood, 2376 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
