Unlock complete reportThe two-unit residential building at 4860 W Cornelia Ave in Portage Park, owned by Ana Maria Bazan, is a 1923 construction that has generated minimal service requests through the city's 311 system over the past seven years. Most notably, there has been an unusual cluster of recent issues in June 2026, with two separate reports for dead animal pick-up requests, both of which remain open as of October 2023, suggesting potential ongoing sanitation concerns in the vicinity. Prior to these recent incidents, the only documented service request was for a tree trimming issue in July 2025, which was properly closed out, though it's worth noting that this type of request is no longer being accepted by the city. While the building's overall service request history appears relatively minimal, the recent pattern of open dead animal pick-up requests may warrant attention to area maintenance conditions.

How 4860 W Cornelia 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
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 3910 buildings in this neighborhood, 352 are predicted to be safer.
