309 West 121st Street, Manhattan, NY 10027

309 West 121st Street is a 5-story, 10-unit Old Law Tenement building located in Harlem, built in 1901 and currently owned by Jay Newhouse. The building has experienced ongoing rodent activity, with 11 inspections between 2024 and 2025 showing consistent rat presence, most recently confirmed in June 2025. Multiple rodent complaints were filed in 2025, with the Department of Health and Mental Hygiene noting recurring issues requiring inspections.

The building has also faced significant maintenance challenges in early 2025, including unresolved complaints regarding heat/hot water (January), ceiling paint/plaster issues, door/window problems, and toilet plumbing issues, all of which were marked as open complaints as of January 2025. These issues led to multiple Housing Maintenance Code complaints, some classified as emergency situations. The property has a history of violations related to bedbug reporting, with the most recent inspection in April 2024 showing no infested units, and previous years (2021-2023) also showing zero infestation cases.

Other historical compliance issues, primarily from 2013, included concerns about heating system access, signage requirements, and maintenance of common areas, though these violations were subsequently closed. A complaint regarding illegal hotel rooms was filed in 2018 but was marked as having insufficient information. Recent maintenance reports show some improvements, with heat/hot water issues being resolved in December 2024, though new complaints have subsequently emerged. The building has maintained regular bedbug reporting compliance since 2019, consistently showing no active infestations during reporting periods.
