186 Knickerbocker Avenue is a 3-story, 4-unit Old Law Tenement building located in Bushwick, built in 1931 and currently owned by Fang Ying Gao. The building has experienced several significant maintenance issues over the past few years, with the most pressing concerns centering around sanitation and safety. As of September 2023, there are open violations related to garbage accumulation in the compactor closet and front areas, a broken entrance door lock, and multiple issues in apartment 3L including pest infestations (both roaches and mice), a missing smoke detector, and a defective kitchen window sash. The building has also had recurring electrical issues, with a recent power outage in August 2023 and a history of electrical complaints dating back to 2021.
Notable safety and sanitary concerns have persisted throughout 2023, including violations related to smoke detectors, carbon monoxide detectors, mold, and various plumbing and flooring issues. Despite these challenges, recent rodent inspections in 2025 have shown compliance with passing results, suggesting some improvement in pest management. The building has demonstrated regular responses to pest control needs, with multiple bait applications recorded in early 2023. Of particular note is the building's bedbug reporting history, with filings in 2021 and 2024 showing no infested units or eradication efforts required during those periods. While many complaints have been inspected and closed by the Department of Housing Preservation and Development (HPD) throughout 2023, the presence of multiple open violations as of September 2023 suggests ongoing maintenance challenges.
