Unlock complete reportThe three-unit residential building at 1115 W 31st Street in Chicago's Bridgeport neighborhood is a 138-year-old property currently owned by Lou Hong. The building's official records over the past seven years reveal two unresolved building violations stemming from periodic routine inspections conducted in November 2019, representing the only documented code compliance issues on record during this period. In terms of maintenance and neighborhood concerns, the property has generated eight 311 service requests between 2025 and 2026, with the most recent being a public vehicle/valet complaint in May 2026. The majority of these requests (five in total) were related to graffiti removal, occurring between April 2025 and May 2026, while one request from March 2025 addressed a rodent issue. It's worth noting that all service requests have been closed, though this does not necessarily confirm their issues have been fully resolved. The building's documented violations and service requests suggest a property that, while generally compliant with building codes, has experienced recurring issues with graffiti and occasional pest problems, typical of an aging urban structure in a dense neighborhood.

How 1115 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
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, 2961 are predicted to be safer.
