Built in 1927 and currently owned by Steven Hoffman, this 6-story, 35-unit Chelsea building has experienced several notable incidents in recent years. Most concerning are two animal-related complaints in late 2024 and early 2025 regarding unpermitted animal facilities, including a reported monkey, though health inspectors were unable to access the property for verification. The building has faced recurring safety and maintenance issues, with multiple open violations as of 2023 related to apartment B's lack of smoke and carbon monoxide detectors, and problems with self-closing doors at building entrances.

A significant boiler violation was recorded in January 2021, detailing operational defects and safety concerns that required correction. While there have been several emergency complaints regarding heat/hot water and cooking gas in past years (most recently in 2022), the building has maintained a consistent record of passing rodent inspections, with the most recent one in October 2024 showing compliance. The building has also shown a pattern of addressing pest issues, with zero bedbug infestations reported in the last three consecutive annual filings (2022-2025), though there were four reported cases in 2019.

The property has a mixed record of responding to violations and complaints, with some issues remaining unresolved for extended periods, particularly regarding fire safety systems and entry doors. Historical data shows various maintenance challenges throughout the years, including heating systems, cooking gas, and electrical appliance concerns, though many of these issues were addressed following inspections. The building's 311 and HPD complaint history, combined with environmental and rodent inspection results, provides a comprehensive view of its ongoing maintenance and safety management.
