331 Grand Street, Manhattan, NY 10002

331 Grand Street is a 4-story, 3-unit residential building located in Chinatown and owned by Mark Weiss. The property, constructed in 1900, experienced significant maintenance issues in April 2019, with multiple complaints regarding heat and hot water systems, cooking gas supply, and safety equipment including smoke and carbon monoxide detectors. These complaints resulted in various Housing Maintenance Code violations, particularly affecting the third-floor apartment, related to inadequate gas supply for kitchen fixtures, hot water issues, and missing or defective self-closing doors.

While most of these violations were certified as resolved by March 2023, they represented a cluster of urgent maintenance problems during that period. In 2025, the building faced scrutiny regarding potential illegal conversions, with two complaints filed - one in May 2025 resulted in a violation notice, while another filed in April 2025 concluded with no violations found at the time of inspection. A related complaint from July 2024 about an adult establishment was assigned to the Mayor's Office of Special Enforcement.

On a positive note, the building has consistently passed rodent inspections from 2019 through 2025, indicating effective pest management. The Department of Buildings records also show the issuance of several permits in July-August 2019, though the specific nature of these permits is not detailed in the available data. The building's recent history suggests improved maintenance standards, particularly regarding safety equipment and basic services, but with ongoing regulatory attention to potential unlawful modifications.
