Unlock complete reportThe three-unit residential building at 933 W 31st Street in the Bridgeport neighborhood, owned by Camilo & Lusa Martinez, has been subject to several notable incidents in recent years. The property, constructed in 1898, has recorded two building code violations in 2025 that were resolved through complaint-driven inspections. There appears to be an ongoing concern with water issues, as evidenced by two leak-related service requests in September 2025 and one additional leak check request in November 2025, which remains open. The building has also experienced issues with open fire hydrants in the vicinity, with two complaints recorded in September 2025, though these were successfully resolved. Prior to the current open leak investigation, there was one building violation complaint in March 2025 that was closed. While the building has had some compliance issues, particularly in 2025, it's worth noting that recent violations have been addressed, though the open leak investigation as of November 2025 merits attention.

How 933 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, 2161 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
