Augrented Insights Report for 509 Hinsdale Street

The 21-unit, 4-story New Law Tenement building at 509 Hinsdale Street in East New York, owned by Barry Singer and constructed in 1930, is currently experiencing multiple infrastructure and maintenance challenges. Between May and June 2025, there were numerous complaints requiring HPD inspections, including issues with windows/doors, appliance malfunctions, sanitary conditions (including pest infestations), plumbing concerns (heavy water leak), and a sewage problem.

Of particular concern is the pattern of HPD being unable to complete inspections for several complaints during this period, which may indicate access issues or other complications. The building has also been under scrutiny for safety compliance, with open violations from late 2024 in apartment 4B relating to various maintenance issues including bathroom fixtures and floor conditions, as well as outstanding safety concerns in apartment 4D regarding missing smoke detectors and carbon monoxide detectors. Historically, the building has faced multiple structural and maintenance issues, including three separate inspections for building stability concerns in 2018-2020, plumbing problems documented in 2018, and several Environmental Control Board violations from 2018-2019 regarding improper installation of plumbing systems in the laundromat space.

More recently, there has been consistent rodent activity observed between 2024-2025, with multiple bait applications recorded. While bedbug reports show no infestations in recent years (2021-2024), the building's maintenance record suggests ongoing challenges with basic infrastructure and safety systems that require attention. The property has maintained compliance with bedbug reporting requirements and appears to have resolved some historical violations, though several open violations from late 2024 remain active as of the most recent data.
