Unlock complete reportThe four-unit building at 2320 W 21st Street in Chicago's Lower West Side, owned by Salvador Lopez, has a documented history dating back to its construction in 1888. The property shows relatively limited recent activity over the past seven years in terms of building permits and violations, with only one building permit and two violations on record. However, there has been a notable pattern of maintenance issues in the past year, particularly regarding pest control and refuse management. Most significantly, there have been three rodent-related complaints (two in September and one in August 2025) and two garbage cart maintenance requests (one in September and one in July 2025), all of which have been marked as closed in the city's 311 system. While these issues have been addressed through the 311 system, the frequency of these complaints within a single year suggests ongoing challenges with building maintenance and sanitation. The property's limited history of building permits and violations might indicate either stable conditions or potential underreporting of maintenance issues, though this cannot be definitively determined from the available data.
How 2320 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, 2278 are predicted to be safer.
