Unlock complete reportThe two-unit residential building at 8231 S Colfax Ave in South Chicago, owned by Theresa Brown and constructed in 1907, has generated five documented 311 service requests over the past seven years. The most recent activity, as of December 2025, involved a yard waste pick-up request, while earlier in March 2025, there was a fly dumping complaint. In October 2024, the building made two separate service requests: one for garbage cart maintenance and another for a water lead test kit, which is particularly notable given the ongoing concerns about lead contamination in older Chicago buildings. Additionally, there was a tree debris clean-up request in June 2024. The relatively low number of service requests over this extended period, combined with the nature of most requests being related to routine maintenance and city services rather than building-specific issues, suggests a generally stable property condition, though the water lead test kit request indicates some attention to water quality concerns.

How 8231 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, 836 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
