186 Jefferson Street, Brooklyn, NY 11206

186 Jefferson Street, a 3-story, 6-unit Old Law Tenement building constructed in 1931 in Bushwick and owned by Chaim Halberstam, has experienced several significant maintenance and safety issues over the past few years. Most notably, between 2023 and 2024, the building has undergone multiple rodent inspections showing consistent rat activity, with the most recent April 2025 inspection passing. The building has maintained a clean record regarding bedbug infestations, with all five consecutive annual reports from 2019 to 2024 showing zero infested units.

The property has faced various regulatory violations and service requests, particularly in 2020-2021. A heat and hot water emergency complaint was filed and investigated in May 2020, resulting in violations. In October 2020, multiple violations were recorded regarding door security and closure issues at the building's front entrance.

The building's safety compliance was further addressed in June 2020, with violations documented for failing to post various required safety notices, including those related to smoke detectors, carbon monoxide detectors, and gas leak procedures. Most of these violations have since been closed, with some certified as resolved in 2023. Recent building management appears to have made efforts to address various maintenance and safety requirements, as evidenced by the filing of annual bedbug reports showing no infestations. However, the persistent rodent activity noted in inspections throughout 2024 and 2025 suggests ongoing challenges with vermin management in the building.
