Unlock complete reportThe property at 946 W 31st Place in Chicago's Bridgeport neighborhood is a two-unit building constructed in 1883, currently owned by Hongjian Zhang and comprising three parcels of land. The building's recent service record shows several concerning patterns, particularly in 2026, with multiple water-related issues including four water-on-street complaints (three of which have been resolved, while one remains open). Early 2026 also saw a rodent-related complaint that has since been closed. The building's history includes at least two other notable incidents in late 2025: a response to a vacant/abandoned building complaint and a building violation, both of which were resolved. The property's total service request count over the past seven years stands at 28 across three parcels, though only seven requests are specifically attributed to the two-unit building.

How 946 W 31St Pl'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
Grade A–B — Low risk
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 3117 buildings in this neighborhood, 1465 are predicted to be safer.
