Unlock complete reportThe six-unit residential building at 5859 W Byron St in Chicago's Portage Park neighborhood, owned by Bronislaw Drag, is a 1917 construction that has experienced a notable cluster of sanitation-related issues in recent years. Between August 2024 and June 2026, there have been six documented sanitation code violations or garbage cart maintenance requests, suggesting ongoing challenges with waste management systems. The most recent sanitation code violation occurred in June 2026, and prior to that, there were four consecutive garbage cart maintenance requests between August and November 2025. An abandoned vehicle complaint was also filed and resolved in August 2025. Looking further back, the building had an asbestos work order complaint in September 2009, which is significant given the health risks associated with asbestos exposure, though no subsequent environmental issues appear on record. The building's overall service request history shows relatively low activity, with only eight total service requests (including two not directly related to sanitation issues) over a seven-year period from the owner's perspective.

How 5859 W Byron St's risk score is calculated

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.
