Augrented Insights Report for 850 50th Street

850 50th Street is a 4-story, 16-unit New Law Tenement building in Borough Park, constructed in 1931 and currently owned by Chen Yuen Cheng. The building has experienced recurring safety issues in 2024, specifically regarding window guards, with two separate complaints in April and May of that year, though no violations were ultimately issued. More concerning are the ongoing construction lead dust complaints in May 2024 and April 2024 that are still marked as in progress.

The building has a documented history of heat and hot water issues, with two separate emergencies reported in 2019 and 2022, though both were resolved relatively quickly. Several recent violations from 2024 require attention, including broken window sashes in public areas on the 1st and 2nd stories, a defective self-closing door at the 4th story bulkhead, and a defective door at the 1st story vestibule. The property has undergone various inspections and received multiple violation notices over the years, with a particular focus on safety and maintenance issues.

In 2020, there was a notable violation regarding an electrical pulley setup on the fire escape that was resolved with a $1,250 penalty. The building's annual bedbug reports from 2020 to 2024 show no infestation cases, with all units reported as free of bedbugs during the inspection periods. The building has also experienced multiple inspection-related access issues, including a 2019 illegal conversion complaint and a 2020 construction enforcement work order, where inspectors were denied access on the second attempt. While most violations and complaints have been addressed and closed, the current lead dust complaints and the pattern of window guard issues suggest ongoing maintenance concerns that merit attention.
