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

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

Out of 3683 buildings in this neighborhood, 3167 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
