Augrented Insights Report for 317 Knickerbocker Avenue

317 Knickerbocker Avenue is a 4-story, 6-unit residential building in Bushwick, constructed in 1931 and currently owned by Tom Rosenberg. The building has experienced several recurring maintenance issues over recent years, with the most significant being water-related problems, including a heavy flow water leak reported in May 2024 and multiple water leak incidents between 2020 and 2024. There have been two substantial building-wide emergencies regarding heat and hot water - one in December 2023 and another in 2021.

Additional concerns include pest issues, with a violation noted in January 2021 for roach infestation in apartment 3F and common areas, though subsequent bedbug filings between 2021 and 2024 reported zero infested units. The building has undergone several inspections and repairs, including work on the 4th story public hall where violations were issued for various issues including fire-retardant material, door closures, and roof leaks, though most were certified as corrected by 2023. Of particular note are the gas-related safety concerns from 2019, when multiple violations were issued regarding improperly installed gas piping and appliances, leading to Oath violations being served.

This was followed by a 2025 complaint regarding work without a permit. The building's recent maintenance record shows ongoing rodent activity, with inspections in 2024 documenting rat activity in December 2023 and multiple bait applications throughout 2024. The property has maintained compliance with bedbug reporting requirements, showing zero infestation cases in the most recent filings from 2022-2024. While the building has experienced various maintenance challenges, records indicate that most violations have been addressed, though some open violations remain from 2021 regarding elevator door systems and 2021 for public hall cleanliness, and there are ongoing concerns about water infrastructure and plumbing systems.
