856 Knickerbocker Avenue, Brooklyn, NY 11207
856 Knickerbocker Avenue is a three-story, four-unit New Law Tenement building constructed in 1910 and currently owned by Ramin Khomari. The property has experienced ongoing pest management challenges, with multiple rodent-related incidents documented between 2023 and 2025, including repeated instances of rat activity and the application of bait in 2024, though the most recent inspection in April 2025 showed passed compliance. The building has several open violations of concern, including three Bedbug Report violations from 2021 to 2024 that remain unresolved.
Between 2020 and 2021, there were significant infrastructure issues, including emergency plumbing problems related to water supply and cooking gas, as well as pest control violations specifically citing roach infestation in apartment 3R. The property has undergone various inspections and treatments for rodent activity, with the most recent showing improved conditions. Other notable historical issues include multiple food establishment complaints in 2021 related to hygiene and sanitation, and a 2020 violation for missing carbon monoxide detectors in apartment 3R, along with a cooking gas supply violation issued in June 2021 that has since been closed. The building's maintenance history reveals a pattern of recurring pest control needs, with approximately ten documented instances of rodent activity or bait application between 2023 and 2025.
More recently, the property has shown some improvement in pest management, with the April 2025 inspection passing compliance. However, the persistence of open violations related to bedbug reporting requirements and the building's age suggest ongoing maintenance challenges. The most recent complaint filed in January 2025 regarding work without a permit could indicate potential unauthorized modifications, though the inspector was unable to gain access for verification. The property's documented history features a mix of resolved and ongoing issues, with significant attention required for bedbug reporting compliance, though other major infrastructure issues have been addressed.
