123 West 142nd Street, Manhattan, NY 10030
The six-story, 18-unit building at 123 West 142nd Street in Harlem, owned by Janette Mosley and built in 1920 as a New Law Tenement, has experienced persistent heating and maintenance issues in recent months. Between January and February 2025, there were multiple complaints about inadequate heat and hot water affecting the entire building, with violations documented in apartments 10 and 6 related to both heating and hot water problems.
These heating issues sparked emergency complaints and multiple 311 service requests, though access challenges hindered some inspections. The building has also faced concerning safety issues, particularly in apartment 16, where violations were documented in December 2024 for missing smoke and carbon monoxide detectors, inadequate heating, and visible mold in the bathroom.
Additional maintenance challenges have emerged, including rodent activity as recently as July 2025, with multiple inspections in 2024-2025 consistently showing rat activity. The building's heating system has come under scrutiny, with at least two boiler-related complaints filed in January 2025, though inspectors were unable to gain access during initial attempts. While the building appears to have maintained a bedbug-free status since 2019, as per the required reporting periods, the combination of persistent heating problems, recent safety violations, and ongoing pest control challenges suggests significant building maintenance and management issues that have persisted into 2025.
