Unlock complete reportThe two-unit residential building at 3924 W Byron Street in Irving Park, owned by ICG INC, has a century-old history dating back to 1910. Over the past seven years, the property has experienced multiple maintenance and sanitation issues, with the most recent incidents occurring in 2026 including a fly dumping complaint and a water-in-basement issue. Notably, between February and September 2025, there were recurring pest control challenges, with two documented rodent-related complaints within a short span of time, along with a garbage cart maintenance issue. The building's service request history shows a pattern of sanitation concerns, particularly in 2025, which appears to be the most problematic year in recent records. Despite these service requests, the property has only required two building permits in the past seven years, suggesting limited structural modifications or major improvements during this period. The ownership structure is somewhat complex, with ICG INC holding four total parcels in this vicinity, though this arrangement does not necessarily correlate with the building's unit count.
