Unlock complete reportThe two-unit residential building at 4843 N Kostner Ave in Chicago's Albany Park neighborhood, constructed in 1923 and currently owned by A & N Laboy & S Ogrady, has had a limited but notable service request history over the past seven years. The property has generated a total of ten 311 service requests, with the most recent incident being a stray animal complaint filed in May 2026. While the building's overall service request volume is relatively low for its age, some concerning patterns have emerged in recent years. Of particular note is an open water lead test kit request from September 2025, which warrants attention given its potential implications for resident health and safety. The property has experienced several maintenance-related issues, including rodent problems (August 2025), garbage collection discrepancies (missed pick-up in December 2024), and waste management concerns (garbage cart maintenance in August 2025). Additionally, a tree trim request was submitted in October 2024, though it's worth noting that this particular type of request is no longer being accepted by the city.
