Unlock complete reportThe 444 E Ontario building in Streeterville, built in 1987 and containing 624 units, has experienced several significant issues in recent years. Most notably, there has been a cluster of building code violations in 2026, with multiple open and unresolved complaints as of April 2026, though some violations from earlier in the year had been resolved. The property has also faced recurring environmental concerns, particularly regarding noise, with multiple complaints documented between 2023 and 2025, including a pair of resolved noise complaints in September 2025 and another alleged violation in November 2023. The building's maintenance record shows a total of 42 building violations and 32 service requests over the past seven years, with recent requests including an open water lead test kit request from May 2026. Additionally, there were several 311 service requests related to building violations and consumer fraud in 2026, though some of these have been resolved. While the property has obtained ten building permits over the past seven years, the persistence of recent violations and complaints suggests ongoing maintenance and regulatory compliance challenges.

How 444 E Ontario 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.
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 26 buildings in this neighborhood, 26 are predicted to be safer.
