Initial analysis

The 3-unit residential building at 4639 S Komensky Ave in Archer Heights, owned by Ernestina Pina, has been standing since 1951. Over the past seven years, there have been five documented service requests through the 311 system, with the most recent occurring in January 2026 regarding snow removal. The requests cover a range of issues, including a rodent baiting complaint in January 2026, tree trimming in January 2025, blue recycling cart services in December 2024, and a dead animal pickup request in October 2024. While all service requests have been closed, the presence of multiple pest-related incidents (the rodent complaint and the dead animal pickup) within this period may be of particular note regarding the building's maintenance conditions. The variety of service requests also suggests the building has experienced typical urban maintenance issues rather than any one specific recurring problem.

Risk rating

How 4639 S Komensky Ave'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
