273 South Avenue, Staten Island, NY 10303

The property at 273 South Avenue in Mariners Harbor is a 2-family house built in 1910 and currently owned by Dong Li. The building has experienced recurring issues with water leakage, most recently documented in April 2025 as a heavy flow water leak that resulted in HPD violations.

This follows a pattern of water-related problems, including a slow leak complaint in 2021, along with multiple unresolved issues from April 2021 inspections that included unsanitary conditions (pests), flooring problems, and wall maintenance needs - though HPD was unable to gain access to inspect these conditions. Significantly, the property had a notable incident in late 2020 involving an illegal apartment conversion. Multiple violations were issued in November 2020 concerning an unauthorized Class A apartment in the rear garage with full kitchen, bathroom, and gas range facilities, which were confirmed through Department of Buildings inspections.

The violations, classified as B-level, required correction of the illegal conversion and related plumbing fixtures, while an illegal occupancy violation and $2,500 penalty were also issued through the Environmental Control Board. Although the property passed a rodent inspection in August 2016, there have been no documented pest control Follow-Up inspections. Other maintenance issues have included electrical lighting problems in December 2019 and a temporary heat/hot water problem in November 2020, though these were resolved without violations.
