452 St Nicholas Avenue, Manhattan, NY 10027
452 St Nicholas Avenue is a 5-story converted New Law tenement building in Harlem, built in 1901 and currently managed by owner Stanley Celius. The property has experienced recurring maintenance issues in recent years, with particular concern around heating and hot water systems. Between June 2024 and May 2025, there were multiple emergency complaints regarding heat and hot water across the entire building and individual apartments, with some violations still pending correction.
Cooking gas supply issues have also been documented, particularly affecting apartments 1A and 2A, with violations issued in December 2024 and November 2024 respectively. The building's infrastructure has shown persistent challenges, including a slow water leak cited in December 2024 that resulted in violations being issued. Recent maintenance records indicate problems with basic safety systems, including two Class B violations in November 2024 for missing carbon monoxide detectors and smoke detectors in apartment 4A, though these were certified as corrected by December 2024.
The building has also faced rodent control challenges, with multiple inspections between 2024 and 2025 recording rat activity, though some inspections also showed compliance with rodent control requirements. While there have been some exterior maintenance issues noted in recent years, including a $5,000 penalty for improper storage on a sidewalk shed in March 2023, and a current violation regarding unfiled low-pressure inspection records from September 2024, the most pressing concerns appear to be centered around building systems and safety equipment. The property has maintained a clean record regarding bedbug infestations, with no reported cases over the past six reporting periods from 2020 to 2025.
