364 West 121st Street, Manhattan, NY 10027

364 West 121st Street is a 5-story, 15-unit old-law tenement building in Harlem, constructed in 1909 and currently owned by 364 West 121 Street HDFC. The building has experienced recurring issues with heat and hot water, with the most recent complaint filed in October 2023 concerning the entire building, though inspectors were unable to gain access to verify the problem.

A series of maintenance issues were documented throughout 2022, including work orders and violations related to unsanitary conditions (pests and mold), plumbing problems (radiators and bathtub/shower), paint and plaster issues, and window frame concerns. Notably, there was one self-closing door issue identified in Apartment 1A in October 2023 that required repairs. The building had multiple emergency classified complaints in 2022, though most have been resolved without violations being issued upon inspection.

The property has maintained a strong rodent control record, passing all inspections from 2017 through 2025, and has shown good compliance with bedbug reporting requirements, with no reported infestations in the last three years of filings (2022-2025). There was a period of concerning maintenance issues in 2022, with multiple violations related to heat, water, and general upkeep, including an outstanding violation from April 2023 regarding an external low-pressure inspection that remains active as of the latest available data. While the building has resolved many of its previous complaints and violations, the recurring nature of heat and hot water issues, particularly in the most recent year, remains a significant concern for resident comfort.
