57 Cooper Street, Manhattan, NY 10034
The four-story, six-unit residential building at 57 Cooper Street in Inwood, owned by Diana Blaser and constructed in 1989, has experienced numerous maintenance and safety issues over recent years. Most concerning are the 311 service complaints in 2025 regarding heat/hot water issues that HPD was unable to inspect, and ongoing problems documented through multiple Housing Maintenance Code complaints in 2025 for unsanitary conditions including mold, multiple water leaks, flooring issues, and plumbing concerns.
The building has faced recurring issues with its ventilation systems, plumbing, and heating infrastructure, including a defective boiler complaint in February 2025, though inspectors were unable to gain access during their inspection. Significant violations and complaints from 2024 reveal persistent maintenance challenges, particularly in apartment 2B, where multiple open violations were recorded for issues including defective ventilation, flooring, and cabinet problems. The building has also faced electrical, fire escape, and general safety complaints that, while inspected, did not result in violations being issued.
Recent reports in 2025 indicate rat activity, though prior inspections from 2021 to 2024 generally passed rodent inspections. The property has maintained an active bedbug reporting history showing zero infestation counts in recent years, and while several Housing Maintenance Code violations were closed between 2023-2024, including issues with light fixtures in common areas, there are still ongoing concerns regarding building maintenance compliance. An active ECB violation from February 2024 pertains to improper drainage from a downspout at the rear of the property affecting apartment 2B's terrace.
