210 Knickerbocker Avenue, Brooklyn, NY 11237

The 4-unit, 3-story tenement building at 210 Knickerbocker Avenue in Bushwick, built in 1931 and currently owned by Hua Chen, has experienced several significant maintenance issues in recent years. Most notably, between late 2018 and early 2019, there was a pattern of heat and hot water complaints affecting the entire building, with multiple reports filed through HPD during this period - all of which were either closed due to lack of access for inspection or because heat and hot water had been restored, though one complaint from January 2019 did result in verification of corrections. Additionally, the building faced multiple compliance challenges, including a slow water leak, mold/sanitation issues, and concerns about carbon monoxide detectors in late 2018, all of which were investigated by HPD with no violations issued.

More recently, there is an active violation as of June 2023 regarding the failure to file the 2020 external low-pressure inspection report. The building's recent history shows some improvements in specific areas of concern. Between 2021 and 2025, there have been consistent bedbug reports showing zero infested units and successful eradications for multiple reporting periods.

Recent rodent inspections in 2023-2025 show a mix of improved compliance - with several "Passed" results and some bait applications noted. The most recent inspection in June 2025 passed, suggesting improved conditions. In terms of safety and compliance, there were two bedbug reporting violations in 2021 and 2023, and a gas hook-up complaint in 2024 was investigated with no violations found. The building's management appears to have taken steps towards improved maintenance in recent years, with records showing fewer major complaints and violations since 2019, though the active violation regarding external low-pressure inspection filing from mid-2023 remains outstanding.
