Augrented Insights Report

The property at 1521 Hudson Avenue is a two-unit, two-story multi-family residential building built in 1900, currently owned by Kwan Yoke Man. The building has experienced numerous significant issues throughout 2023, most notably related to unauthorized modifications and water damage. In early 2023, violations were filed regarding an unauthorized horizontal addition containing a bathroom and kitchen, along with multiple building and health-code violations including water damage, hazardous mechanical ducting, and problems with smoke and carbon monoxide detectors.

Several of these violations were addressed by April 2023, including the repair of water-damaged kitchen woods and replacement of a kitchen exhaust duct. However, as of May 2023, there was an active permit filed to legalize an increased roof height of 10 feet at the rear of the building and kitchen relocation, demonstrating ongoing construction work. More recently, in October 2024, plumbing work was completed to address drain vent issues in Unit B, suggesting continuing maintenance needs.

The building has a history of various complaints and violations that indicate potential habitability concerns. These include a 2023 complaint about lead hazard warnings, a 2023 violation regarding non-compliant egress windows, and multiple instances of plumbing-related issues including leaks and drainage problems. The property has also faced several 311 calls regarding maintenance and compliance issues, particularly during late 2022 and throughout 2023, including multiple citations for illegal parking near the property and concerns about garbage and debris on the property. While some violations have been resolved, there remain active concerns regarding proper permits for building modifications and compliance with safety requirements.
