Augrented Insights Report for 150 West 21st Street

The 6-story, 61-unit building at 150 West 21st Street in Chelsea, owned by Mark Scharfman, has experienced several significant maintenance and safety issues in recent years. As of April 2025, there are three open complaints with the Department of Housing Preservation and Development (HPD) regarding paint/plaster issues, flooring problems, and an electrical/gas range appliance concern.

Between February and March 2025, multiple heat/hot water complaints occurred, including an entire building issue in February and an apartment-specific problem in March, though some were subsequently reported as resolved. The building has undergone multiple rodent inspections in 2025, with several instances of rat activity reported, prompting regular bait applications. The property has a history of various violations and safety concerns, including multiple Housing Maintenance Code violations in 2019-2021 regarding smoke detectors, carbon monoxide detectors, floor repairs, and more in apartments 2H and 5D.

Recent elevator maintenance issues were reported in late 2024 but were found to have no violations upon inspection. Notably, there is an active Environmental Control Board violation from 2022 regarding the failure to submit a required exterior wall report, with a penalty imposed of $625. While the building has maintained a pest-free record in recent years according to Bedbug Reporting data, the ongoing maintenance issues and rodent activity suggest persistent challenges with building upkeep and resident comfort.
