11 Chatham Square, Manhattan, NY 10038

11 Chatham Square is a 5-story, 20-unit residential building located in Chinatown, owned by Henry Cheung and constructed in 1915. The building has experienced several significant maintenance and safety issues in recent years, most notably in 2024, when multiple emergency complaints were filed regarding mold, smoke detector, and carbon monoxide detector problems, all of which were subsequently closed within ten days.

The building has also faced infrastructure challenges, including a December 2024 heat and hot water complaint that was resolved through HPD intervention. A fire incident was recorded in April 2024 affecting apartment 2B, along with various Housing Maintenance Code violations including issues with door self-closing mechanisms, fire egress obstructions, and apartment-specific maintenance needs.

Recent inspections have identified several open violations from late 2024 related to building safety and habitability, including defective doors at the rooftop bulkhead, a kitchen gas supply issue in apartment 2B, and various problems in apartment 3B where violations were issued for broken plaster surfaces, illegal locking devices, and missing safety equipment. The building's mechanical systems have also been under scrutiny, with Department of Buildings violations regarding unauthorized rooftop AC units and problematic boiler equipment. However, it's worth noting that the building has consistently passed rodent inspections over multiple years (2020-2025) and has maintained a clean record for bedbug infestations since 2019, with no reported incidents in the past six years.
