6 West 123rd Street, Manhattan, NY 10027

6 West 123rd Street is an 8-unit, 3-story residential building in Harlem, constructed in 1882 and currently owned by Us Manhattan Ii Housing Corp. The property has experienced persistent heating and hot water system issues over the past year, with multiple complaints filed between 2023 and 2025, including recent reports in February 2025 and August 2024 where inspectors could not gain access to the building for verification.

The building received several Emergency Housing Maintenance Code Violations in 2024, including an open violation related to a cockroach infestation in Apartment 5, and multiple issues with heating and hot water systems. Notably, there were also safety concerns addressed in 2024, including missing smoke and carbon monoxide detectors in Apartment 5 and a violation regarding access to the heating system in the boiler room. The property has undergone regular rodent inspections, with mixed results; while recent inspections in 2025 passed, there were failures noted in late 2024 and 2021.

The building has maintained a consistent record of bedbug-free status, with no reported infestations in the past eight years (2018-2025). Recent building permits from 2019 indicate some form of work was performed, though specific details on the nature of the work are not provided in the available data. The building's age and history of system-related complaints suggest ongoing maintenance challenges, particularly concerning heating and hot water infrastructure, which have been the primary focus of tenant complaints over the past two years.
