Unlock complete reportThe four-unit residential building at 1637 W 21st Street in Chicago's Lower West Side, owned by Robert Rasmussen, is a 1877 structure that has experienced routine urban maintenance issues over the past seven years. The property has generated a total of seven 311 service requests, with two additional requests at other locations associated with the same owner. Most recently, in December 2025, there was a reported incident of graffiti that required removal services, followed by two separate recycling-related requests in February 2025 for cart maintenance and a blue recycling cart, suggesting some challenges with waste management infrastructure. Earlier, in July 2024, another graffiti removal request was submitted, indicating this issue has occurred multiple times. While the building's service request history shows regular municipal interaction, it's worth noting that the nature of these requests primarily relates to external maintenance and waste management rather than internal building conditions or safety concerns, and all reported issues have been resolved as evidenced by their "Closed" status.
How 1637 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
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, 2829 are predicted to be safer.
