Initial analysis

This two-unit residential building at 3556 S Wolcott Ave in Chicago's McKinley Park neighborhood was constructed in 1913 and is currently owned by J & M Hernandez. The property has experienced several notable events over the past two years, with a total of six 311 service requests filed between 2024 and 2025. The most recent incidents include a building violation investigation in March 2025 and a tree trimming request in March 2025, though the latter is no longer being accepted. Environmental and infrastructure issues have been a recurring theme, with two related complaints in June 2024 regarding water issues and an open fire hydrant condition on the street. Additionally, there was a rodent-related complaint in September 2024 that was subsequently resolved. The property's most recent service request, filed in May 2024, pertains to a tree planting initiative, which remains open and under consideration. While the building's age may contribute to some of these issues, the relatively small number of total service requests over the past seven years (six in total) suggests that while there are some maintenance and environmental concerns, they are not excessively frequent for a structure of this age.

Risk rating

How 3556 S Wolcott 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.
