Unlock complete reportThe two-unit residential building at 2603 W Walton St in Humboldt Park, owned by Piotr Sokolowski, is a century-old structure dating back to 1912. Over the past seven years, the property has generated numerous service requests, totaling five, with varying concerns. The most recent activity involves an open water lead test kit request from March 2024, which is particularly noteworthy as it relates to potential health and safety concerns about the building's water quality. In late 2024, there was a rodent-related complaint, indicating possible pest control issues at that time. The property owner has submitted three tree-related requests in 2025, including two trim requests in April and one planting request in February, though the tree trim requests are no longer being accepted. During this seven-year period, the building's permit activity has been minimal, with only one permit recorded. While most service requests have been properly closed, the open water quality testing request warrants attention as the only remaining unresolved issue on the current record.

How 2603 W Walton St'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 6211 buildings in this neighborhood, 3168 are predicted to be safer.
