Unlock complete reportThe two-unit residential building at 6628 N Washtenaw Ave in Chicago's West Ridge neighborhood is a 1921 construction currently owned by Keesoon Kim. The property has generated a total of nine service requests through the 311 system over the past seven years, with the most recent incidents occurring in June 2026 involving tree-related emergencies and debris. Notably, there was a significant infrastructure concern in April 2026 with a water in basement complaint, which has since been closed. The building's maintenance record shows multiple tree-related requests in late 2025, including two tree trim requests in November, while earlier service requests included an abandoned vehicle complaint in August 2025. The service request pattern suggests ongoing maintenance attention is required for both tree and water-related issues near the property, though most previous complaints have been successfully closed.
How 6628 N Washtenaw 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.
Out of 3105 buildings in this neighborhood, 2018 are predicted to be safer.
