Initial analysis

The two-unit residential building at 3307 S Wallace St in Chicago's Bridgeport neighborhood, owned by Qian Dong and Ru Hua Liu, has a notable history since its construction in 1891. There have been eight building code violations recorded in the past seven years, with the most recent being an unresolved complaint-driven inspection from April 2026, which raises particular concern given its current open status. A significant cluster of violations occurred in July 2024, though these were all resolved. The property has generated two 311 service requests related to building violations in recent years; one from June 2024 and another from October 2025, both of which were closed. Additionally, there has been one building permit issued in this seven-year period. While some historical issues have been addressed, the combination of recent violations and the current open violation from 2026 suggests ongoing regulatory challenges for this property.

Risk rating

How 3307 S Wallace 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.
