401 East 89th Street, Manhattan, NY 10128

401 East 89th Street is an 18-story, 197-unit residential building on the Upper East Side, built in 1963 and currently owned by Michael Troise. The property has experienced ongoing pest control challenges, with 14 rodent-related complaints filed in 2025 alone, most recently in June 2025, showing persistent rat activity and resulting in multiple violations requiring follow-up inspections by the Department of Health and Mental Hygiene.

The building has a notable history of infrastructure and maintenance issues, including a 2024 partial vacate order for the parking garage due to concrete deterioration and water penetration concerns. Recent complaints and violations indicate continuing safety and maintenance concerns, including active Department of Buildings violations for failure to file required inspection reports and safety violations related to scaffold and safety net maintenance.

The property has had several emergency heat and hot water complaints in recent years, with one such incident recorded in late 2023 when inspectors were unable to access the building. Additional maintenance issues have included concerns about ventilation systems, lead dust in common areas, and various code violations that remain unresolved or were only partially addressed, such as missing building signage and inadequate gas leak emergency procedures. While the building has maintained a clean record for bedbugs over the past several years, the frequency and nature of recent rodent control efforts suggest ongoing challenges with building maintenance and resident comfort.
