523 Willoughby Avenue, Brooklyn, NY 11206

523 Willoughby Avenue is a 4-story, 8-unit residential building located in Bedford-Stuyvesant, constructed in 1910 and currently owned by Arje Halberstam. The property has experienced several significant infrastructure issues in recent years, most notably in early 2024 when there were simultaneous reports of a power outage and lack of heat/hot water affecting the entire building, though inspections by the Department of Housing Preservation and Development (HPD) found no violations.

Prior to this, in 2023, there were documented issues with both mold and pest infestations, though again, no violations were found upon HPD inspections. The building has a history of water-related problems, including a notable heavy flow water leak documented between July 2020 and March 2021. The property has undergone regular inspection for rodent activity, with the most recent inspections in 2025 and late 2024 showing compliance passed; however, there were instances of rat activity noted in mid-2023, indicating some continuity of pest management challenges.

The building's maintenance history includes three Department of Buildings permits issued between 2018-2019 for various work, including two for "EW" (presumably elevator work or electrical/water systems). While the building has demonstrated proactive management in addressing infestation issues, as evidenced by multiple pest control inspections, it's noteworthy that during the 2023 inspections, there were reports of rat activity despite passing compliance checks. The bedbug monitoring program shows no reported infestations over the past six years, indicating successful management of this particular pest issue.
