Augrented Insights Report for 4123 9th Avenue

The four-story, 38-unit tenement building at 4123 9th Avenue in Borough Park, owned by Yehoshia Sturm, has experienced several maintenance challenges in recent months. Between February and May 2025, there were multiple complaints about unsanitary conditions, including issues with pests and garbage/recycling storage, leading to violations being issued. There was also an incident involving heat and hot water complaints in February 2025, and problems with electric/gas ranges in multiple instances.

The building underwent a significant inspection in November 2024 (A2) which revealed several maintenance issues, including the presence of mold, lead paint hazards, and rodent activity, while also documenting necessary repairs to various surfaces and systems. The property has faced historical compliance challenges, including two active ECB violations from November 2022 related to unauthorized occupancy and construction work in the cellar area, with associated fines of $2,500 each. Previous concerns include a 2022 illegal conversion case that resulted in a partial vacate order.

Building systems appear to have had some issues, as evidenced by a boiler complaint in late 2024 where inspectors were unable to gain access, though there were no violations recorded at the time. Notably, while there have been persistent pest control issues throughout the building's history, including recent rat activity detections in 2024 and 2015, bedbug infestations have been remarkably low, with no reported cases in the past five years. The building has also maintained relatively good compliance with bedbug reporting requirements, consistently showing eradication efforts and zero current infestations.
