Unlock complete reportThe two-unit residential building at 4209 N Whipple St in Chicago's Irving Park neighborhood, owned by Thomas Nawrocki, is a 1913 structure that has had minimal documented activity over the past seven years. The building's official records show only one building permit filed during this period, which is notably low for a property of its age and size. There have been nine 311 service requests logged in the same timeframe, with all of these requests occurring between July and November of 2025. The majority of these recent requests (five out of nine) were related to blue recycling cart services, while two were for yard waste pick-up, and one was concerning a tree removal inspection. All these service requests have been marked as closed, indicating they were addressed by city services. While the frequency of service requests in 2025 is somewhat notable for a two-unit building, it appears to be primarily related to standard city services rather than pressing maintenance or safety concerns.
How 4209 N Whipple St'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 3714 buildings in this neighborhood, 111 are predicted to be safer.
