Unlock complete reportThe three-unit residential building at 4907 N Washtenaw Ave in Lincoln Square, owned by Joseph Grubb, is a 1924 structure that has experienced minimal documented activity over the past seven years. The property has generated 15 311 service requests during this period, with the most recent being a graffiti removal request in May 2026. Of particular note, there are currently two open bicycle-related complaints from 2026, suggesting ongoing issues in this area. The building's maintenance record shows three tree trimming requests made in December 2025, though it's important to note that the city no longer accepts such requests through the 311 system. The only building permit filed in the past seven years was issued to address a roof repair project in August 2023, which represents the most significant structural work on record during this period.
How 4907 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, 1436 are predicted to be safer.
