338 Knickerbocker Avenue, Brooklyn, NY 11237
The property at 338 Knickerbocker Avenue is a 3-story, 4-unit, old law tenement building constructed in 1931 and currently owned by Gina Castro. The building has experienced recurring issues with heating systems, most recently documented in late 2023 when HPD inspectors were unable to gain access to verify complaints about building-wide heat and hot water problems.
There are multiple open violations regarding the failure to file annual bedbug reports from 2021 through 2024, which are classified under the NYC Housing Maintenance Code. The building has also faced significant safety concerns, particularly in 2018 when multiple violations were documented in apartment 3F, including problems with window guards, fire escape access, and self-closing doors. A series of inspections and complaints between 2023 and 2024 revealed various maintenance issues, including electrical problems, plumbing concerns, and unauthorized work.
Most notable is the active Environmental Control Board violation from March 2024 regarding unpermitted electrical work in both the building and the attached restaurant. The property has undergone several rodent inspections between 2022 and 2025, with the most recent results indicating ongoing rat activity as of June 2025. While some permits were issued in 2019 for electrical work, the building has experienced persistent maintenance challenges, particularly regarding compliance with housing regulations and ongoing pest control issues.
