Augrented Insights Report for 850 40th Street

The 36-unit, 4-story New Law Tenement building at 850 40th Street in Borough Park, owned by Gary Brown, has experienced recurring maintenance issues over recent years, with particular concerns regarding heating systems and water-related problems. Most notably, the building has faced multiple heat and hot water outages, with three separate emergency complaints in early 2024 alone, including one that affected the entire building.

Water-related issues have also been frequent, with heavy flow leaks reported in 2023 and most recently in April 2025, resulting in violations that require correction by the property owner. The building has undergone several inspections and received multiple violations during 2024-2025, including issues with self-closing doors at fire exits, lighting problems, and various maintenance needs in Apartment C5 such as flooring, cabinetry, and plaster repairs.

While the building has faced administrative violations regarding energy efficiency score displays between 2021 and 2024, these were ultimately dismissed. There is a documented history of bedbug infestations in 2020-2021, though no reported cases in recent filing periods (2021-2025). The property has a pattern of emergency complaints requiring HPD intervention, suggesting ongoing challenges with building maintenance and prompt resolution of tenant-reported issues.
