1749 2nd Avenue, Manhattan, NY 10128
Knickerbocker Plaza, a 40-story high-rise built in 1975 on the Upper East Side, currently has several pressing issues requiring attention. Most concerning is an open complaint from May 2025 regarding construction lead dust in common areas, and another from March 2025 about allegedly selling banned tobacco flavors. The building has experienced recurring heat and hot water issues, with complaints filed in both December 2023 and February 2025, though inspectors were unable to gain access to verify these problems.
Recent inspections and violations reveal various maintenance concerns, including multiple apartments (5G, 13T, 20S, 24F, 11F, and 10D) exhibiting issues such as mold growth, pest infestations (including roaches), and defective electrical outlets. There is also an active issue regarding the building's parking structure that has resulted in an ECB violation from October 2024, with a penalty of $2,500 for failing to submit required inspection reports. The building has faced multiple pest control challenges over the past few years, with documented bedbug cases in units showing patterns from 2019 through 2024, and recent rodent inspections in 2024 and 2025 indicating rat activity.
Maintenance of safety systems appears to be an ongoing concern, with multiple violations dating back to 2023 regarding the failure to submit high-pressure inspection reports. The property has experienced structural concerns as evidenced by a building vibrating complaint from October 2024. Other notable issues include various sanitary conditions, food-related complaints, and a history of tenant complaints about tobacco-related violations. While many past issues have been resolved, the building continues to experience recurring problems with moisture, pests, and infrastructure maintenance, as evidenced by recent complaints and ongoing violations.
