Initial analysis

The two-unit building at 1819 W 21st Street in Chicago's Lower West Side, owned by Rosario Mena, is a modest two-flat structure built in 1888. The property's service request history over the past seven years shows minimal activity, with only one recorded 311 service request in July 2025, which was related to an open fire hydrant complaint. This particular incident, while requiring attention from city services, appears to have been resolved promptly as the status is marked as closed. The building's documented history shows very few service requests overall, which could indicate either excellent maintenance practices or potentially incomplete records, though this is purely speculative. Given the age of the building, constructed over 135 years ago, it has presumably undergone various modifications and maintenance over its lifetime, though no specific details about such work are available in the current records.

Risk rating

How 1819 W 21St St 1'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.

Neighborhood percentile
77thpercentile
