Unlock complete reportThe 5-unit residential building at 1644 W 21st Street in Chicago's Lower West Side, owned by 1644 W 21st Street LLC, is an 1886 structure with a concerning history of unresolved building code violations. Over the past seven years, there have been six complaint-driven inspections that resulted in violations, with four of these inspections occurring in 2019 alone, including three that remain open as of now. The building's records also show six 311 service requests between 2024-2025, primarily related to nuisance animal complaints (three instances) and two tree planting requests in February 2025, which have all been addressed and closed. While the recent tree planting requests indicate some interest in property improvements, the persistence of open building code violations, particularly from 2019, raises questions about the building's current condition and the owner's compliance with building codes.

How 1644 W 21St 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.
Out of 3683 buildings in this neighborhood, 3057 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
