109 Seaman Avenue, Manhattan, NY 10034
The 41-unit, 5-story New Law Tenement building at 109 Seaman Avenue in Inwood, built in 1918 and owned by Issac Katz, has experienced recurring heating system challenges over the past five years. Notably, between late 2020 and 2021, there were multiple complaints (at least 10 documented incidents) about heat and hot water issues affecting the entire building, with emergency housing maintenance code violations filed in January and October 2021.
More recently, the building has encountered some administrative compliance issues, including three active violations from 2021-2022 regarding the failure to properly display energy efficiency scores and grades, as well as a benchmarking report requirement. On the pest front, the building has maintained a relatively good record, with no bedbug infestations reported since 2022, and only one documented case in late 2019-2020.
The property has undergone several rodent inspections between 2022 and 2025, showing a mixed but generally improving pattern - with three instances of "Rat Activity" noted in early 2024, though the most recent inspection in June 2025 resulted in a "Passed" status. A known construction/renovation permit was issued in December 2018, related to work in unit 2A, though this led to a subsequent violation in 2021 for electrical work done without proper permits. The building's overall condition presents an ongoing need for attention to heating system reliability and ensuring compliance with energy reporting requirements, while showing improvements in pest control and rodent management in recent inspections.
