Unlock complete reportThe three-unit, 1920 residential building at 4857 N Washtenaw Ave in Lincoln Square, currently owned by Lori Kawamoto, has experienced several noteworthy service issues in recent years. The most recent documented incident was a rodent baiting complaint in May 2026, following earlier concerns about a potential leak in May 2026 and an improper tree maintenance request in March 2026. The property has also faced basic infrastructure challenges, including a missed garbage pickup in June 2025, an alley pothole complaint in April 2025, and street light pole damage in April 2025, all of which were subsequently resolved. Notably, the building's permit activity has been minimal during this period, with only one building permit recorded in the past seven years, which might suggest limited structural modifications or improvements to the property. The frequency of 311 service requests, totaling 16 over the past seven years, while not uncommon for an older building, indicates some ongoing maintenance issues that have required municipal intervention.
How 4857 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 2564 buildings in this neighborhood, 1820 are predicted to be safer.
