Unlock complete reportThe three-unit residential building at 8543 W Winnemac Ave in Chicago's O'Hare neighborhood is a single parcel property constructed in 1968, currently owned by Charles N Coon. The building's record over the past seven years shows minimal activity, with only one documented 311 service request and one building permit application on file. The sole service request, filed on March 3, 2026, concerned a missed garbage pick-up, though this issue has since been resolved according to the closed status. The building's permit activity appears to be equally limited with only one permit application recorded, though the specific nature and outcome of this permit is not detailed in the available data. The lack of multiple service requests or permits could indicate either stable building conditions or potential underreporting, but no definitive conclusions can be drawn from the limited available data.

How 8543 W Winnemac 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
Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Higher risk — riskier than most nearby
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 444 buildings in this neighborhood, 373 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
