Unlock complete reportThe two-unit residential building at 624 W 31st Street in Bridgeport, owned by MBZ PROP LLC, is a historic structure dating back to 1891. The property has experienced several notable incidents over the past seven years, with the most significant cluster of issues occurring in late 2022 when six complaint-driven violations were documented on November 9th, though it is worth noting that all these violations have since been resolved. While the building has maintained a relatively low number of permits - with only one recorded in the past seven years - it has generated consistent service requests, totaling 18 complaints. These requests primarily relate to street lighting issues, with two recent complaints about non-functional street lights on May 27 and 28, 2026, as well as other municipal service needs including graffiti removal (both in December 2025 and April 2026), tree trimming (March 2026), and an injured animal report (May 2026).

How 624 W 31St St'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 3132 buildings in this neighborhood, 3132 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
