Unlock complete reportThe two-unit residential building at 1817 W Patterson Ave in Chicago's North Center neighborhood, owned by Blake Itagaki, has a century of history dating back to its 1908 construction. The property's most recent activity over the past seven years, while relatively minimal, has included some concerning patterns. Most notably, there have been two separate rodent-related incidents in the past three years (June 2026 and July 2024), suggesting a recurring pest control issue that may impact resident comfort. Additionally, the building's surroundings have required attention to basic infrastructure, with documented requests for alley pothole repair in April 2026, and a tree trim request in August 2025, though the latter type of service is no longer being accepted. While there have been no documented health or safety violations in the recent seven-year period, the frequency of pest-related complaints and infrastructure issues in the immediate vicinity warrants attention when considering the property's maintenance history.
