Augrented Insights Report for 520 Jefferson Avenue

The 4-story, 8-unit tenement building at 520 Jefferson Avenue in Bedford-Stuyvesant, owned by Yvette Adams, has experienced recurring heating issues in recent years, with three heat/hot water complaints logged between 2023 and 2025, including violations issued in November 2024. The building, constructed in 1910, has also faced significant maintenance challenges, particularly evident in a cluster of complaints from May 2023 involving various issues such as plumbing problems in bathtubs, sinks, and multiple instances of paint/plaster concerns on walls and ceilings.

More recent inspections from 2024-2025 have revealed multiple open violations, including issues with electrical wiring, self-closing doors, and water temperature problems specifically affecting apartment 3D. Despite these challenges, the building has maintained a relatively clean record regarding pest control, with recent bedbug reports (2025-2024) showing no instances of infestation, and successful rodent inspection passes in 2022, 2024, and 2025 indicating effective maintenance in this area.

Past violations related to door hardware and water fixtures from 2023 have been addressed, though some older violations from late 2024 remain open. The building's management has demonstrated compliance with annual bedbug reporting requirements, consistently filing reports showing no infestation cases. While the property has experienced recurring heating issues and various maintenance concerns, recent rodent inspections and bedbug reporting suggest improved pest management practices.
