The building has experienced recurring issues with heating, hot water, and electrical systems over the past few years, with multiple complaints between 2020-2024 regarding power outages, no lighting, and heating system failures affecting the entire building. Most recently, in May 2024, there was a power outage that was investigated by HPD but resulted in no violations.

The building has maintained a consistent record of bedbug reporting with zero infested units reported in the last several years, dating back to at least 2019.
