Unlock complete reportThe three-unit residential building at 4200 N California Ave 1 in Irving Park, owned by Norman W Gin, has been standing since 1956 and has experienced a notable pattern of maintenance events over the past several years. Most significantly, in October 2019, the building was subject to six complaint-driven inspections that resulted in violations, though records indicate that all of these violations have been resolved. Looking at more recent activity, there is currently an open concern regarding sidewalk conditions, with two inspection requests filed in June 2026 that remain unresolved. The property has also faced some infrastructure issues in the surrounding area, with three pothole complaints filed between March and December 2025, and one street light pole damage complaint in April 2026; however, all of these external issues have been appropriately addressed according to system records. The building's violation and service request record spans a total of 13 violations and 14 service requests over the past seven years, with the majority of issues appearing to be resolved through proper channels, though the recent sidewalk concerns suggest ongoing maintenance attention may be warranted.
