511 West 159th Street, Manhattan, NY 10032
The 5-story, 18-unit tenement building at 511 West 159th Street in Washington Heights, constructed in 1910 and currently owned by 18 Holdings Group LLC, has experienced several maintenance issues in recent years, particularly during 2025. Most notably, there were heat and hot water problems reported in March 2025 affecting the entire building, though inspectors were unable to gain access for verification. Multiple complaints were filed in March 2025 regarding various maintenance issues, including plumbing, appliance problems (still open as of March 2025), wall conditions, and floor issues.
The building underwent inspections in August 2024 that revealed multiple violations requiring attention to safety systems and infrastructure, including missing smoke detectors and carbon monoxide detectors in apartment 10, roof leaks affecting the 5th floor bulkhead, and various fire safety concerns in public areas. The property has maintained a consistent record of passing rodent inspections from 2016 through 2024, though there was at least one failed inspection in 2016. Bedbug reports for the building between 2019 and 2024 show no infestation cases.
Recent complaints filed in June 2025 indicate ongoing issues, specifically related to the mailbox system and pest control. Between 2020 and 2024, the building underwent various compliance matters, including two illegal conversion investigations (2021 and 2025), though hearings and inspections resulted in varying outcomes, including Oath Violation Service in 2025. The Department of Buildings has issued several permits for work on the property, with the most recent permits issued in March 2019 for electrical and plumbing work.
