Augrented Insights Report for 464 West 23rd Street

464 West 23rd Street is a 4-story, 10-unit residential building in Chelsea, constructed in 1857 and currently owned by Peter Tran. The property has experienced recurring water-related issues, with the most recent complaint filed in May 2025 remains open regarding heavy water flow, following multiple reports of mold and water leaks between September and October 2023.

The building has faced several infrastructure challenges, including heat and hot water problems reported in November 2020, and a door/window issue in February 2019. A significant matter currently under investigation involves potential illegal occupancy, with active violations from October 2023 regarding an unauthorized duplex conversion of unit 1F between the basement and cellar, including concerns about a spiral staircase installation and occupancy contrary to the Certificate of Occupancy.

Recent violations identified during an October 2023 inspection included several concerning building safety and maintenance issues, though most have been resolved through subsequent certifications, such as fire safety concerns involving ceiling materials and sprinkler system requirements. The building's maintenance history shows no reported bedbug infestations since at least 2019, and it has consistently passed rodent inspections from 2010 through the most recent inspection in October 2024. While the building has had multiple 311 complaints and Housing Maintenance Code violations in recent years, most have been addressed and closed, with the exception of the current water leak issue and the illegal occupancy situation.
