521 3rd Avenue, Manhattan, NY 10016

521 3rd Avenue is a 5-story, 4-unit old law tenement building in Murray Hill, built in 1920 and currently owned by Chris Meskouris. The building has experienced several significant maintenance issues in recent years, including an ongoing food poisoning complaint filed in March 2025 with the Department of Health and Mental Hygiene.

A notable heat/hot water emergency in December 2022 affected the entire building, particularly impacting Apartment 2, and resulted in multiple violations including inadequate heat supply and locked access to the heating system. While the building has maintained compliance with bedbug reporting requirements from 2021 through 2025, with no reported infestations, it did receive a Class A violation in April 2024 for failing to file the annual bedbug report. The building has undergone multiple rodent inspections and remediation efforts between 2018 and 2025, with the most recent inspection in March 2025 resulting in a pass, suggesting improved conditions.

There was also a complaint about work being done without permits in 2024, which was referred to the Department of Consumer Affairs. During 2022, multiple food establishment complaints were filed regarding rodents, insects, and garbage issues, though these were subsequently addressed. The building's maintenance history shows a pattern of heating system-related issues and pest management requirements, though recent inspections indicate improvements in both rodent control and bedbug management compliance.
