Initial analysis

The two-unit residential building at 1820 W 21st Place in Chicago's Lower West Side, owned by Palemon Santana, is a century-old structure dating back to 1902. The property has recorded a total of eight 311 service requests over the past seven years, with the most recent activity occurring in August 2025, consisting of routine waste management services including blue recycling cart and garbage cart maintenance, along with a sewer cleaning inspection request - all of which have been successfully closed. Noteworthy is a July 2024 rodent baiting complaint that was addressed and closed, indicating some concerns about pest control in the vicinity. Looking forward, there is an open request from February 2025 for tree planting, which, while not directly affecting current resident conditions, reflects potential improvements to the property's immediate environment. The building's service request history appears to be relatively routine in nature, primarily focused on waste management and sanitation services, with no recorded incidents suggesting serious maintenance or safety concerns.

Risk rating

How 1820 W 21St Pl 2'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
