427 Knickerbocker Avenue, Brooklyn, NY 11237

The three-story, six-unit residential building at 427 Knickerbocker Avenue in Bushwick, owned by Sammy Hajibai, has a documented history of construction activity and regulatory compliance issues spanning several years. Built in 1931, this Old Law Tenement has undergone various construction work between 2019 and 2021, during which multiple violations were documented, including construction work not conforming to approved documents, and failure to maintain required site documents.

In late 2020 and 2021, issues with the sidewalk shed/scaffold system were recorded, including a vehicle strike incident in 2020 and a related violation for an expired permit that was subsequently resolved. The building experienced structural concerns in 2020, with a complaint about building shaking/vibrating/structural stability affecting residents, though this violation was ultimately resolved.

More recently, the building has shown improvements in regulatory compliance, with no documented bedbug infestations since 2022 (with annual reports showing zero infested or re-infested units), and all rodent inspections from 2022 through 2025 showing "Passed" results, with only one failed inspection in late 2020 for unspecified reasons. The bedbug reporting requirements appear to be fulfilled for the 2022-2023 and 2023-2024 periods, with no recorded infestations during these reporting periods. The property has shown consistent effort in addressing previous violations and maintaining compliance with housing maintenance codes, particularly in terms of pest control and rodent management, though the building's history does show periods of construction-related regulatory challenges and safety concerns between 2019 and 2021.
