621 Flatbush Avenue, Brooklyn, NY 11225

Located at 621 Flatbush Avenue in Prospect-Lefferts Gardens, this four-story, nine-unit New Law Tenement building was constructed in 1909 and is currently owned by Abe Betesh. The property has experienced persistent maintenance issues over the past few years, with the most recent cluster of complaints in May 2025 involving plumbing problems (sinks and bathtubs), a water leak, flooring issues, and window frame concerns, all resulting in HPD violations. The building has a documented history of plumbing problems, water leaks, and pest issues, particularly focused in apartment 2B, where multiple violations remain open as of September 2024 regarding water leaks, mold, plumbing fixtures, and pest infestation.

Building systems violations are also a concern, with multiple active violations related to the failure to file high-pressure inspection reports for 2020-2023. The property has had several safety and maintenance incidents requiring attention, including emergency complaints in 2025 regarding smoke and carbon monoxide detectors. There were also three significant complaints in 2024, including building shaking/vibration, which resulted in an Oath violation.

While the building has maintained a clean record regarding bedbug infestations since 2021, there have been ongoing rodent control efforts documented through multiple bait applications throughout 2023-2024, with periods of rat activity noted in August 2023, October 2023, and May 2024. The building has experienced multiple water-related issues, with slow leaks reported in 2024 and 2025, as well as various window and door maintenance requirements. The property's maintenance history suggests ongoing challenges with basic building systems and infrastructure, requiring regular intervention from housing authorities.
