225 West 146th Street, Manhattan, NY 10039
The 43-unit, 6-story New Law Tenement building at 225 West 146th Street in Harlem, built in 1920, has experienced several significant maintenance issues in recent years under the ownership of Louis Koplowitz. Most notably, there have been recurring heating and hot water system problems, with emergency complaints recorded in October 2024 for the entire building and individual apartments.
Additionally, plumbing issues have been documented throughout 2024, including problems with bathtubs, sinks, and toilets, though inspectors were often unable to gain access for verification. The building has also faced challenges with unsanitary conditions, including infestations of pests and reports of mold, particularly affecting the bathroom ceiling in apartment CBA. The property has a history of regulatory non-compliance, with various Housing Maintenance Code violations noted between 2023 and 2024, including issues with window repairs, plaster surface conditions, and maintenance of common areas.
While recent inspections have generally passed rodent control checks in 2023-2025, there were notable rat activity reports in 2020, 2021, and 2022. The building's maintenance history also shows some recurring administrative issues, such as failure to file required boiler inspection reports and energy-related documentation, though many of these violations were ultimately dismissed upon proper filing. Bedbug reports from 2019 through 2024 show zero infestations, suggesting effective pest management in this regard.
