510 Manhattan Avenue, Manhattan, NY 10027

The five-story, 10-unit tenement building at 510 Manhattan Avenue in Harlem, built in 1901 and currently owned by Jay Newhouse, has experienced recurring maintenance issues over the past two years. Most notably, there have been multiple heat and hot water-related complaints in 2024 and 2025, with the most recent incident occurring in April 2025. The building has also faced issues with unsanitary conditions, including mold and pest infestations, particularly affecting apartment 2B, which experienced documented violations in 2024.

Plumbing issues, including problems with sinks and basins, have been reported and subsequently addressed. Inspections between 2023 and 2025 have consistently indicated the presence of rodent activity, with the most recent June 2025 inspection confirming this issue. While the building has a history of bedbug infestation reports, the most recent filings from 2024 and 2025 show no current infestations. The property has undergone various inspections and violations through the Department of Buildings (DOB), including a construction-related stop work order in 2022 that was eventually rescinded.

An ECB violation related to a window A/C unit's support brackets was issued in September 2023, though no penalties were imposed. Between 2018 and 2020, there were reports of illegal hotel room usage, which could not be substantiated. The building has maintained regular bedbug reporting compliance from 2019 through 2024, typically reporting zero infestations. Recent improvements to the building's maintenance response can be seen in the relatively prompt closure of many complaints, though the recurring nature of heat and rodent issues suggests ongoing challenges with building systems and pest control.
