509 West 121st Street, Manhattan, NY 10027
The 8-story New Law Tenement at 509 West 121st Street, built in 1911 and currently owned by Thomas Bailey, has experienced several notable incidents in recent years, with the most pressing being a recent heat and hot water complaint in November 2024 that required HPD intervention, though inspectors were unable to gain access to verify the conditions. The building has persistent violations related to its facades, with both active ECB violations as of 2024 indicating failures to correct unsafe conditions and properly file reports, including an outstanding penalty of $1,280.
There is also an active DOB violation from 2021 regarding the non-display of energy efficiency scores and another from 2022 concerning "swamp" conditions that remain pending disposition. The building's maintenance record shows a relatively recent pattern of bedbug management, with one reported incident in the most recent filing period (2023-2024) where one unit was infested and subsequently treated.
However, prior to this, there had been no reported infestations for several consecutive years (2020-2023). On a positive note, the building has consistently passed multiple rodent inspections from 2016 through mid-2025, demonstrating effective pest control measures in place. The property, consisting of 110 units, has experienced these issues while maintaining compliance with regular rodent inspections, suggesting ongoing attention to general maintenance requirements despite some concerning safety and habitability issues that have emerged, particularly regarding heat systems and facade maintenance.
