Unlock complete reportThe two-unit residential building at 8312 S Colfax Ave in the South Chicago neighborhood, owned by Marvell Valentine, is a century-old property constructed in 1910. The building's recent history (2017-2023) shows relatively few issues overall, with only one building code violation recorded in September 2019, which has since been resolved. The property has generated a total of seven 311 service requests over the past seven years, with the most recent three occurring in 2025, all related to street infrastructure and maintenance issues including street light outages (September 2025), tree debris (August 2025), and a traffic signal outage (May 2025). Prior service requests from 2024 comprised two tree debris clean-up requests (November 2024) and a weed removal request (June 2024), along with another street light outage complaint (April 2024). While the volume of service requests indicates some ongoing maintenance needs in the immediate vicinity, these issues have primarily related to street infrastructure and public spaces rather than the building itself. The only historical environmental complaint on record dates back to 1994 and concerned air pollution, though no subsequent issues of this nature have been reported in recent years.

How 8312 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
