Augrented Insights Report for 850 Amsterdam Avenue

850 Amsterdam Avenue is a 20-story, 119-unit Class A residential building constructed in 1931, currently owned by Bldg Amsterdam LLC. The building has experienced recurring heating and hot water issues over the past two years, with multiple complaints filed throughout 2024 and 2025, including recent heat-related problems as of April 2025. The building has also faced various maintenance challenges, including plumbing issues (bathtub/shower problems in November 2024), and paint/plaster concerns in October 2024 affecting both walls and ceilings.

More recently, in April 2025, there is an open complaint regarding unsanitary conditions related to pests. The building's maintenance history shows a mix of resolved and ongoing issues. Notably, there was a significant pest infestation in apartment 6C documented in March 2023, along with multiple violations regarding various maintenance problems in that same unit, including plumbing, refrigerator, and infestation issues.

The property has undergone rodent inspections showing consistent passing results except for one instance of rat activity in September 2023. In terms of infrastructure, there are recent concerns regarding electrical systems, with an active ECB violation from June 2024 regarding unauthorized electrical work in apartment 13E, and previous complaints about wall conditions. The building has a documented history of periodic bedbug infestations, though recent filings (2022-2024) show no active cases. While some maintenance issues have been addressed promptly, the recurring nature of heating and pest-related complaints suggests ongoing challenges with building systems and maintenance response.
