421 West 43rd Street, Manhattan, NY 10036

The five-story, 17-unit New Law Tenement building at 421 West 43rd Street in Hell's Kitchen, constructed in 1910 and currently owned by Ninth Avenue Realty LLC, has experienced several recurring maintenance issues over the past decade. Most notably, from 2018 to 2019, there were multiple reports of mold-related unsanitary conditions, with at least five separate complaints registered during 2018-2019, though inspections typically found no violations. The building has also faced water-related problems, including a significant water leak reported in January 2019, and heating issues that same month, though inspectors were often unable to gain access to conduct proper evaluations.

Other maintenance concerns included door and window frame issues in August 2018, with violations documented for door repairs. More recent concerns include a 2021 asbestos investigation where inspectors couldn't gain access, and two illegal conversion complaints in 2021 and 2025, both resulting in access issues during inspections. The building has also had three housing maintenance code violations in 2019 related to mold conditions in basement Apartment B2, kitchen cabinets, and a blocked drain.

However, the property has demonstrated recent improvements in terms of pest control, with no bedbug infestations reported in the past four years (2021-2024), and successfully passed rodent inspections in 2024, 2019, and 2018. The building's management has maintained annual bedbug reporting compliance since 2021, showing consistent attention to this particular issue. While the building has experienced persistent maintenance challenges, particularly regarding moisture control and access-related inspection issues, recent records indicate improved management of pest control and a reduction in reported violations.
