This is the former Brandreth Pill Factory in Ossining, NY. According to Wikipedia:

The former Brandreth Pill Factory is a historic industrial complex located on Water Street in Ossining, New York, United States. It consists of several brick buildings from the 19th century, in a variety of contemporary architectural styles. In 1980 it was listed on the National Register of Historic Places.

Most of the original buildings succumbed to fire in the 1870s, but the oldest, a Greek Revival building possibly designed by Calvin Pollard in the 1830s, remains. Nearby is a corrugated iron structure that may be the earliest use of that material in Westchester County.The main building itself was one of the first to have Otis elevators installed.

Benjamin Brandreth made his family’s popular medicine, said to treat blood impurities, at the factory, starting in the 1830s. The factory’s construction was the beginning of the industrial development of the Ossining waterfront. It continued to be used for manufacturing until the 1940s. Some of the smaller buildings remain in use today, although the former main building is vacant. The village is considering a proposal to convert it to green housing.

An article by former Ossining Mayor Miguel Hernandez paints a bleak picture. In it he says:

One of the major concerns of the neighbors is that it appears that Plateau Associates has engaged in the practice of “Demolition By Neglect” by failing over the years to protect the building from unchecked ruin. Apparently, they made no efforts to fix the leaking roof, the broken windows and other apertures that let damaging weather elements, animals and unauthorized persons into the structure. In this way, they could later make a claim that it is not economically feasible to adaptively reuse the historic factory for housing, as they originally stated several years ago. Demolition by neglect occurs when an owner, with malicious intent, lets a building deteriorate until it becomes a structural hazard and then turns around and asserts the building’s advanced state of deterioration as a reason to justify its demolition.
