Unlock complete reportThe two-unit residential building at 6017 W Byron Street in the Dunning neighborhood, owned by Mary Eustace Zwolinski, has been standing since 1920 and has generated a total of 14 service requests over the past seven years. The most significant cluster of recent issues involves rodent problems, with two rat complaints filed in May 2026, showing a concerning pattern of pest control issues. Earlier in 2026, there was a service request regarding garbage cart maintenance, and in late 2025, there were two separate requests related to blue recycling cart maintenance, indicating ongoing waste management concerns. These service requests suggest challenges with building maintenance and sanitation practices, particularly in waste disposal systems, though the building has had only one building permit filed in the past seven years, which is worth noting for a structure of its age. The total number of 311 service requests and their variety, primarily focused on waste management, paint a picture of a building facing some routine maintenance challenges, particularly in terms of sanitation and pest control.

How 6017 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

Out of 1070 buildings in this neighborhood, 685 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
