Unlock complete reportThe two-unit residential building at 5439 W Windsor Ave in the Portage Park neighborhood was constructed in 1957 and is currently owned by Nizar T Hasan. The property has generated a total of six documented 311 service requests over the past seven years, with all requests having been resolved. The most recent request, submitted in November 2025, was for a water lead test kit and has been closed. Notably, there was a significant cluster of parking-related issues in May 2024, with three separate vehicle sticker violations and two parking code enforcement reviews occurring within a week of each other, suggesting a temporary but concentrated concern about parking compliance in the vicinity. The only other service request on record was for a vehicle sticker violation in June 2024, which was also resolved. While the building's overall service request record is relatively low for its age and number of units, the concentration of parking-related incidents in mid-2024 stands out as the most significant pattern in the property's recent history.

How 5439 W Windsor 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
