Augrented Insights Report for 4102 5th Avenue

4102 5th Avenue is a 4-story, 5-unit residential building located in Sunset Park, constructed in 1931 and currently owned by Lilan Wu. The building has experienced recurring heat and hot water issues, with significant incidents in 2024 (entire building) and 2019-2020 (apartment only), both designated as emergency complaints.

Multiple concerns about garbage and recycling storage have been reported, with violations issued by HPD in 2023. The building is currently facing several open Housing Maintenance Code violations from a June 2023 inspection, including concerns about fire escape access, missing notices for carbon monoxide detector requirements, smoke detector requirements, and gas leak procedures, as well as issues with household items blocking egress from fire escapes on multiple floors.

The property has a documented history of rodent-related problems, with multiple inspections showing rat activity between 2010 and 2020, though recent bedbug reports for the past five years (2020-2024) indicate no infestations. Food safety concerns have been reported in 2024-2025, with multiple complaints to DOHMH regarding pests, though these appear to be related to mobile food vendor activity outside the building rather than internal conditions. The building's records show a mix of resolved and ongoing issues, with management responsibilities for many of the open violations requiring attention to building safety systems and documentation requirements.
