Unlock complete reportThe six-unit residential building at 3902 W Byron St in Chicago's Irving Park neighborhood, owned by Manfred & Waltraut Kru, is a 1916 structure with limited recent activity on its record. Over the past seven years, there have been a total of 26 service requests made through the 311 system, with the majority of these complaints occurring in early 2026. Notable recent concerns include three pothole complaints in the street within just a few weeks (two of which remain open as of May 2026), a sewer cave-in inspection request that has been closed, and an abandoned vehicle complaint that was resolved in March 2026. Additionally, there was a closed vicious animal complaint from December 2025. Meanwhile, the building's permit activity shows only one building permit request in the past seven years, though the record does not specify its nature or outcome. The concentration of service requests in early 2026, particularly related to street maintenance issues, may indicate broader infrastructure concerns in the immediate area, though these are external to the building itself.

How 3902 W Byron 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 3714 buildings in this neighborhood, 2637 are predicted to be safer.
