Unlock complete reportThe 16-unit, 1925 residential building at 4240 W North Chicago in the Humboldt Park neighborhood, currently owned by Constantine Foca, has had a limited number of recorded incidents over the past seven years, with a total of six 311 service requests. The most recent service request occurred in February 2026 for a pet wellness check, while the previous year (2025) saw three separate incidents requiring attention: two graffiti removal requests (one in January and another in February) and a pothole complaint in February. Prior to these, the building experienced a sign repair request in November 2024 and a restaurant complaint in June 2024. It's worth noting that the majority of these service requests relate to exterior maintenance and neighborhood issues rather than direct building safety or maintenance concerns, and all recorded incidents have been marked as closed.

How 4240 W North Chicago'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.
