20 Warren Street, Manhattan, NY 10007

20 Warren Street in Tribeca is a 5-story, 4-unit commercial altered Class A building constructed in 1915, currently owned by Jack Ancona. The property has experienced multiple significant issues in recent years, most notably concerning building safety and maintenance. As of 2024-2025, there are active violations related to the failure to file required external low-pressure inspections from 2018-2023, and a 2021 violation remains active regarding the fire escape system.

The building has a documented history of building code compliance issues, particularly concerning an illegal conversion of transient use on the 3rd floor, which led to multiple enforcement actions between 2019-2021. Additional concerns include recurring problems with heat and hot water in March 2023, a period of plumbing complaints, and multiple food establishment violations between 2022-2025 involving rodent/insect issues and health department interventions. The building has shown some improvement in recent inspections, with passed rodent inspections in 2022-2025, and recent bedbug reports (2023-2025) showing no infestations.

However, there were multiple housing maintenance code violations in 2021 regarding various apartment conditions in Unit 2, including issues with flooring, tiles, and water leaks, all of which were subsequently addressed. The property has experienced several health department investigations, including multiple food poisoning complaints in 2022-2025, though most were determined to be isolated incidents. There were also administrative violations related to the fire escape system that required correction, and concerning the building's annual bedbug reporting compliance. While some past violations have been resolved, including certain housing maintenance issues from 2021, the building continues to face challenges maintaining compliance with various safety and maintenance requirements, particularly regarding its fire safety systems and required inspections.
