Unlock complete reportThe two-unit residential building at 1710 W 21st Street in Chicago's Lower West Side neighborhood is an 1883 structure currently owned by Rosa Yanez. Over the past seven years, there have been seven documented 311 service requests associated with the property. Most recently, in May 2026, there was an abandoned vehicle complaint, and in November 2025, a graffiti removal request. Of particular note is an open sidewalk inspection request from June 2025, which suggests a potential ongoing concern regarding pedestrian safety or accessibility. Earlier in 2025, there were two complaints filed regarding uncleared sidewalks following snow events in February, indicating weather-related maintenance challenges, though these were subsequently closed. Additionally, there was a tree planting request in February 2025 that appears to have been addressed. The building's service request history shows a relatively low volume of complaints for a two-unit building over this timeframe, with most issues being resolved through appropriate channels.
How 1710 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, 625 are predicted to be safer.
