The armory was decommissioned in 1994 and purchased by the Diana family from the State of New York in 1995. In 2005 the Phemister family purchased the building, and continued the extensive renovation, utilizing green building techniques in addition to creating a new residence wing, a billiard room and three new bathrooms. The property is currently in use as a private residence, bed and breakfast and distribution facility. Of the 100 armories built in New York at the turn of the century, only several dozen are still in use as active armories, and Amsterdam Castle is the only armory converted into a private residence.
