820 St Nicholas Avenue, Manhattan, NY 10031

820 St Nicholas Avenue is a 35-unit, 6-story New Law Tenement building located in Harlem and constructed in 1907, currently owned by Guadalupe Rivera. The building has experienced recurring issues with heat and hot water across all units, particularly evident in 2024-2025 with multiple emergency complaints filed through HPD and Housing Maintenance Code complaints. From December 2024 to May 2025 alone, there were at least nine reported incidents requiring HPD intervention, though inspections were frequently unable to gain access to verify the conditions.

The building has also faced rodent infestation challenges, with multiple inspections between October 2023 and March 2025 documenting rat activity, though the most recent inspection in March 2025 showed bait application. In terms of building maintenance and safety, several violations were noted in 2024, particularly concerning Apartment 26, which had issues with broken plaster surfaces, defective door hardware, and required repairs to its exit door. Apartment 45 was cited for multiple issues including inoperable smoke detectors and carbon monoxide detection devices, as well as water leak problems, though some of these violations were subsequently certified as corrected.

The building's elevator service has been a concern, with complaints about single device operation and lack of alternate service recorded in 2020 and 2024, though inspections found no violations. A notable environmental compliance violation from 2020 regarding failure to file required documentation resulted in a $1,250 penalty, now resolved. While the building has maintained a bedbug-free status since 2019 according to records, the persistent heat and rodent issues suggest ongoing maintenance and infrastructure challenges.
