Unlock complete reportThe two-unit residential building at 8400 S Colfax Ave in South Chicago, constructed in 1918 and currently owned by Tanya J Stewart, has maintained a relatively minimal record of service requests and permits over the past seven years. The building's documented history shows one building permit filed during this period, and a total of seven service requests, with the most recent three occurring in January 2026 related to street lighting issues. While these street light complaints, which were all promptly closed, indicate some concern about exterior lighting in the immediate vicinity, they are primarily related to city infrastructure rather than the building itself. The property has also seen other minor municipal service interactions, including a stray animal complaint in December 2025, a tree trimming request in September 2025 (which was subsequently discontinued), and an abandoned vehicle complaint in July 2025, all of which were resolved. The overall limited number of service requests and permits suggests relatively stable building conditions, though it's worth noting that the majority of recorded incidents relate to street and neighborhood conditions rather than the building itself.

How 8400 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
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 2611 buildings in this neighborhood, 1436 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
