801 St Nicholas Avenue, Manhattan, NY 10031
The 42-unit, 6-story apartment building at 801 St Nicholas Avenue, owned by Cloth 150th Street Lp and located in Hamilton Heights, has experienced several maintenance challenges in recent years, particularly in 2025. The most pressing current issues involve repeated complaints about building-wide heat and hot water problems in May 2025, with similar concerns documented as far back as August 2019. The building has also faced multiple plumbing-related issues, including toilet and bathtub problems in 2025, and has a documented history of ventilation system and window frame concerns.
A significant environmental concern was addressed in February 2025, with a reported issue of mold that was inspected by HPD, though no violations were found. The building's maintenance history reveals recurring boiler-related complaints, particularly between 2019 and 2021, with multiple inspection attempts noting no violations, though an active ECB violation from December 2019 regarding boiler defects and exposed wires was recorded with a penalty. Other notable issues include several unit-specific violations in 2024-2025, such as repairs needed in apartments 2G, 3G, and 5A.
The building's management has generally responded to violations, as evidenced by numerous certified correction notices, though some inspections in 2025-2024 encountered access issues. A rodent inspection in 2025 resulted in a "Passed" outcome, following multiple bait applications and activity reports in 2023. The building has maintained a relatively pest-free record in recent years, with no reported bedbug cases since 2019, and historical records show mostly "0" infested unit counts in annual reports.
