1505 St Nicholas Avenue, Manhattan, NY 10033
The 5-story, 23-unit tenement building at 1505 St Nicholas Avenue in Washington Heights, owned by Karen Sinai and constructed in 1940, has experienced recurring maintenance issues in recent years. Most notably, as of June 2025, there are currently unresolved food contamination concerns under investigation by the Department of Health, and multiple plumbing-related problems have been documented, including bathtub/shower issues (April 2025) and historical water leak and mold problems (2025). The building has also faced various sanitation challenges, with reports of pests and mold in early 2025, though some inspections were unable to be completed due to access issues.
Structural and maintenance concerns have been documented through multiple 311 complaints, including problems with ceilings, doors, and garbage storage. The property has a documented history of façade work and scaffolding issues, particularly regarding a 2019 incident involving improper scaffold use and multiple violations related to construction safety compliance, resulting in various penalties. Notable violations were recorded in 2021-2023, including a broken cornice at the roof front (September 2023) and various repair needs in unit 1C related to plumbing, plaster, paint, and mold.
The building has consistently passed rodent inspections since 2016, and recent bedbug reports (2022-2024) show no infestations. While there have been multiple housing maintenance code violations and complaints, many have been resolved through inspections, though some remain open as of the latest records, particularly those relating to moisture and mold issues in unit 1C from 2021. The most recent violation activity includes a plumbing violation from April 2025 and various inspection attempts in early 2025 for unsanitary conditions, though some were incomplete due to access issues.
