520 Amsterdam Avenue, Manhattan, NY 10024

520 Amsterdam Avenue is a 17-story New Law tenement building located in Manhattan's Upper West Side neighborhood, constructed in 1929 and containing 76 residential units. The property is currently owned by Lauri Weinstein and has experienced significant ongoing heat and hot water issues in early 2025, with multiple complaints filed between February and April 2025 about building-wide temperature problems, though inspectors from the Department of Housing Preservation and Development (HPD) were often unable to access units for verification. The building has also accumulated several open violations since late 2023, including those involving water leaks and defective plaster surfaces in apartments 6A, 7B, and 16D, as well as reports of waterbug infestation in apartment 6A.

Additionally, there are active DOB violations from 2019 regarding building facade maintenance requirements and a failure to comply with a Commissioner's Order. The building's maintenance history shows some concerning patterns, particularly regarding heating systems and water-related issues. Between 2019 and 2024, there were occasional problems with rodent activity, though recent inspections in 2023 and 2024 have shown "Passed" results in rodent inspections.

The building's management has complied with bedbug reporting requirements, showing no infestations reported in the past five years. Several environmental and building safety inspections from 2020-2023 suggest generally prompt attention to compliance issues, though there were some instances of non-compliance with reporting requirements that were later resolved. Notably, the building has maintained a consistent record of zero bedbug infestations since mandatory reporting was introduced, and recent rodent inspections have shown passing results, indicating some improvements in pest management. The property's location and age as a historic New Law tenement suggest typical New York City building characteristics, though the recent heat and water issues are a significant concern for residents' comfort and quality of life.
