304 East 89th Street, Manhattan, NY 10128

304 East 89th Street is a 5-story, 18-unit Old Law Tenement building located in Manhattan's Upper East Side neighborhood, owned by Patricia Annunziata and constructed in 1910. The building has experienced recurring pest-related issues, with multiple documented pest inspections and violations between 2023 and 2025, including recent inspections in May 2025 showing unsanitary conditions and rat activity.

There have also been significant maintenance concerns, particularly regarding heat and hot water systems. In early 2025, there were two separate complaints about heat and hot water issues affecting different parts of the building, though these were reportedly resolved after inspections confirmed restoration of service. The building's most serious current concerns center around open violations from a July 2024 inspection of Basement Apartment 1D, including issues with smoke detectors, carbon monoxide detectors, an infestation of roaches, and several other maintenance problems.

Historical data shows previous building system concerns, including a defective boiler in 2020 that resulted in Environmental Control Board violations. While there have been no reported bedbug infestations in the past three years (2022-2025), the ongoing rodent control challenges, as evidenced by multiple "Rat Activity" findings during the most recent inspections in 2023 and 2024, suggest persistent maintenance and sanitation challenges. The building has experienced several access issues during inspections and complaints investigations, which have sometimes delayed resolution of identified problems.
