123 West 77th Street, Manhattan, NY 10024

123 West 77th Street is a 4-story, 12-unit residential building located in Manhattan's Upper West Side, constructed in 1891 and currently owned by Edmond Cohan. The building has experienced recurring maintenance issues in recent years, particularly in 2023-2024, with multiple reports of water leaks, mold problems, and ventilation system deficiencies. Most notably, Apartment 4A has multiple open violations as of March 2024 related to water leaks, plaster damage, and ventilation system problems in both the bathroom and ceiling areas.

The building has also had longstanding issues with air quality and ventilation, with complaints documented in 2021 and multiple interventions required. The property has a history of water-related issues, with emergency complaints in 2024 regarding heavy flow water leaks and persistent ventilation system problems. While there have been several HPD inspections throughout this period, most notably in early 2024, no violations were issued for some complaints, indicating that not all reported problems were deemed serious enough to warrant formal citation at the time of inspection.

The building has passed multiple rodent inspections from 2015 through 2024, though there was one instance of rat activity noted in September 2018. On a positive note, the building has maintained a clean record regarding bedbug infestations, with no reports of infested units between 2019 and 2025. Recent permit activity (2021-2024) shows regular maintenance work being authorized, including plumbing and electrical permits, suggesting ongoing efforts to address building systems and infrastructure.
