173 West 133rd Street, Manhattan, NY 10030

173 West 133rd Street is a 5-story, 8-unit old law tenement building located in Harlem and owned by Jay Newhouse. The property has experienced recurring maintenance issues over the past few years, with the most recent concerns centered around door/window problems (open since January 2025) and heating systems (both apartment-specific and building-wide heat/hot water issues reported in late 2024 and early 2025). The building has a documented history of unsanitary conditions, including multiple complaints about mold and pest problems in late 2024, though some inspections found the conditions did not violate housing laws.

Several violations were issued in July 2024 related to defective ceiling paint/plaster, and in November 2024 regarding general building maintenance concerns including poor intercom system functionality. The property has experienced consistent rat activity as shown by multiple inspections between 2022 and 2025, though some inspections in 2022-2023 passed. There were significant boiler and gas-related violations in 2019-2020, including unpermitted gas installations and improper ventilation systems, with associated penalties totaling $62,500.

These violations were ultimately dismissed in 2020. The building has maintained a generally low bedbug infestation rate according to reports from 2019 through 2024, with only two incidents (in 2019 and 2022) requiring eradication. Recent service requests also indicate ongoing issues with building systems, including problems with door hardware, intercom systems, and heating infrastructure. Please note that while this summary highlights significant maintenance issues, violations, and service requests, it cannot provide a comprehensive assessment of all aspects of the building's condition or management.
