420 East 89th Street, Manhattan, NY 10128

420 East 89th Street is a 5-story, 15-unit residential building located in the Upper East Side neighborhood, built in 1910 and currently owned by Athanasios Raftopoulos. The property has experienced several maintenance issues in recent years, with the most concerning being a 2025 rodent infestation that resulted in Department of Health violations and follow-up inspections.

In 2023, there was a water supply-related plumbing emergency that required HPD intervention and resulted in two Class C violations for both the vestibule and front entrance doors, which were found to have non-compliant self-closing mechanisms. The building's maintenance history shows generally good compliance with bedbug reporting requirements, with the most recent filings (2024, 2023, and previous years) indicating zero infested or re-infested units. The building has a mixed record of rodent control, with recent inspections in 2025 showing rat activity, while previous years (2017-2024) generally passed initial inspections.

A significant administrative oversight occurred in 2019 when a violation was issued for failing to file the 2017 boiler inspection report, though this was eventually dismissed with a penalty payment. The property has maintained regular bedbug reporting compliance since 2018, consistently showing no active infestations during the reporting periods. While the building has experienced various maintenance issues, the owners have generally addressed violations when cited, as evidenced by the closure of multiple Housing Maintenance Code Violations and Complaints.
