191 Knickerbocker Avenue, Brooklyn, NY 11237

The three-story, four-unit old-law tenement building at 191 Knickerbocker Avenue in Bushwick, owned by Diane Gonzalez, has experienced several significant maintenance and safety issues over recent years. Most notably, from 2020 through 2021, multiple environmental control board (ECB) violations were documented concerning the building's structural integrity, including serious concerns about leaning and separation from adjacent buildings, with penalties totaling over $18,000. These structural issues persisted with active DOB violations recorded in 2023 for failure to complete low pressure inspections between 2018-2022.

The building has also faced repeated heating system problems, with two emergency heat/hot water complaints documented in late 2024 and early 2025. Rodent activity has been a recurring issue, with multiple inspections and baiting efforts recorded throughout 2024, and significant rat activity noted as recently as April 2025. The building's maintenance history shows some positive developments, particularly in bedbug management, with the most recent reports (2024-2025) showing no active infestations.

Previously, four units were treated and eradicated of bedbugs in 2023-2024. The property has experienced some access issues for inspections, both for heat complaints in December 2024 and for pest concerns in 2018, which limited authorities' ability to assess conditions. While some historical structural concerns seem to have been addressed, as evidenced by the resolution of several 2020-2021 ECB violations, the building continues to face challenges with heating systems, pest control, and rodent issues, as demonstrated by the ongoing service requests and inspections through 2025.
