643 2nd Avenue, Manhattan, NY 10016
This 6-unit, 4-story Old Law Tenement building located at 643 2nd Avenue in Murray Hill, built in 1920 and currently owned by Joel Radmin, has experienced multiple maintenance issues in recent years, with particular concerns emerging in 2024. Most notably, there are **ongoing heat/hot water issues** as of October 2024, which have been classified as an emergency situation. The building has also experienced recurring **plumbing problems**, particularly affecting sinks and water supply systems, with multiple complaints in 2024 that HPD was unable to fully inspect.
Other maintenance issues include **window frame problems**,** appliances require attention (specifically electric/gas range issues)**, and various other plumbing concerns throughout 2024, with some resulting in violations. The most recent inspection in October 2024 revealed multiple open violations in Apartment 2, including **pest infestation (cockroaches)** and various maintenance issues with windows and floors, while an August 2024 inspection cited inadequate cold water supply in the bathroom basin. The building's history includes several significant events related to safety and compliance.
During 2022, there were concerns about **scaffold safety** and **building facade maintenance**, with violations issued regarding sidewalk sheds and exterior walls. A 2022 compliance inspection noted issues with the exterior building wall and safety net, resulting in fines. The building was previously listed as structurally compromised in 2022, though this violation was ultimately dismissed in April 2025 following the acceptance of the final inspection report. While there have been occasional reports of rat activity throughout the past years (most recently in March and April 2025), the building has maintained a consistent record of having no bedbug infestations reported in the past several years, with the last known occurrence dating back to 2017-2018.
