Unlock complete reportThe two-unit residential building at 5236 W Byron St in Portage Park, owned by Marian Kusiak, has a recorded history primarily within the past two years, with all significant events occurring in 2022. The 108-year-old property experienced multiple complaint-driven inspections on March 23, 2022, resulting in seven building code violations, though it is worth noting that all these violations were resolved and complied with following the inspections. Additionally, the building faced an air pollution-related environmental complaint in August 2022, which was also successfully resolved within two weeks. While the records show one 311 service request related to a Blue Recycling Cart in November 2025, this appears to be a future-dated entry error, and the building has had no other documented service requests, building permits, or violations in the past seven years beyond these documented 2022 incidents.

How 5236 W Byron 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
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 3924 buildings in this neighborhood, 3335 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
