223 Knickerbocker Avenue, Brooklyn, NY 11237

The 6-unit, 3-story tenement building at 223 Knickerbocker Avenue in Bushwick, owned by Eric Mann, has experienced several significant maintenance issues over the past two years. Most notably, there have been multiple reports of water-related problems between December 2024 and February 2025, including heavy flow leaks and damp spots, as well as unsanitary mold conditions, though HPD inspections found no violations except for one water leak complaint where violations were issued. In early 2025, there was also a heat and hot water complaint that could not be inspected due to lack of access.

The building has been issued multiple active violations for failure to file external low-pressure inspections between 2019-2023, and there remains an open violation from May 2024 regarding missing smoke and carbon monoxide detectors in apartment 3L, as well as other safety-related violations including a defective entrance door and encumbrances in public areas. The property has had its share of electrical issues, including a power outage and lighting problems reported in June 2024, and various maintenance concerns in 2023-2024 such as a defective refrigerator and flooring issues. While the building's recent bedbug reports from 2023-2025 show no current infestations, there was one reported case in 2019.

The building has undergone regular rodent inspections, with the most recent in June 2025 passing without issues, though there were multiple bait applications in mid-2023 indicating previous rodent activity. Past violations include a 2020 finding regarding maintenance failure in apartment 2R related to collapsed ceiling covering and piping. The pattern of complaints and violations suggests ongoing maintenance challenges, particularly regarding building systems and safety features, though many recent complaints have been closed without violations being found during inspections.
