Unlock complete reportThe four-unit residential building at 2300 W 21st Place in Chicago's Lower West Side, owned by Tao Duan, has been standing since 1880. The property has experienced several concerning patterns over the past seven years, with particular attention needed to unresolved building code violations. A cluster of six complaint-driven inspection violations was recorded on February 18, 2022, which remains open and unresolved as of the latest data. The building's recent service history shows an ongoing concern with infrastructure maintenance, as evidenced by an open alley sewer inspection request filed in October 2025. The property has generated a notable volume of service requests, with 60 recorded under the owner's name, though many of these (including a snow-cleared sidewalk complaint and an ice removal request) relate to public way maintenance rather than building-specific issues. The only building permit on record in the past seven years was issued for general maintenance work in 2018. While the property has had several resolved issues, including graffiti removal and an abandoned vehicle complaint, the concentration of unresolved violations from 2022 and the recent sewer inspection warrant particular attention to the building's maintenance history and response to infrastructure concerns.

How 2300 W 21St 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 3674 buildings in this neighborhood, 3454 are predicted to be safer.
