521 Vanderbilt Avenue, Staten Island, NY 10304

The two-family residential building at 521 Vanderbilt Avenue in the Clifton neighborhood, owned by Xiangxiang Vuong, has experienced several significant events over the past two years, with the most recent being a sewage leak incident in April 2025 that required intervention from the Department of Health and Mental Hygiene, resulting in a violation that remains under monitoring. In 2023, the property was the subject of multiple concerning complaints, including reports of building shaking and structural stability concerns in May, though these were ultimately resolved with the rescission of a vacate order in June 2024.

During this period, a violation was issued requiring the building's structure to be sealed in accordance with Department of Buildings rules, though this violation was dismissed in June 2024 after inspections confirmed that renovations and repairs had been properly completed and a structural report was on file. The two-story, 1915-built building has two residential units and has seen its most serious issues relate to structural concerns and water-related problems.

While the 2023 structural issues were addressed and formally dismissed, the 2025 sewage leak incident represents the property's most recent maintenance challenge. The building's documented history suggests that while significant issues have arisen, they have generally been addressed through proper channels, with official inspections confirming compliance with required repairs and modifications.
