Unlock complete reportThe three-unit residential building at 4729 N Washtenaw Ave, located in the Lincoln Square neighborhood, is a 1919 structure currently owned by Frank Karabetsos. The building's recent history, particularly over the past year, has been marked by several water-related issues, with three separate incidents of basement water problems reported between July and November 2025. These concerning events appear to have been addressed, as they are marked as closed in the 311 service request system. More recently, there have been multiple active maintenance requests in 2026, including three open requests for sewer cleaning inspections within a two-month period (the most recent being in May) and two water-related inquiries - a lead test kit request and another sewer cleaning inspection request, both still open as of early May 2026. The building's overall service request volume remains relatively low for a three-unit property, with only 10 total 311 service requests recorded in the past seven years, though it's worth noting that the owner has only obtained one building permit in this same timeframe. The relatively high concentration of water-related issues in recent months, including both basement water problems and sewer inspection requests, suggests ongoing concerns with the building's water infrastructure that merit attention.
How 4729 N Washtenaw Ave 1'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, 1897 are predicted to be safer.
