In 1953, a small group of local businessmen discovered the Co-Op concept as defined by the FHA Regulation 213 under the Cooperative Housing Act. These entrepreneurs dedicated themselves to finding people who were willing to sign up and buy into what became 2101 Cooperative, Inc. By January of 1953 financing was in place, the land lease was executed, the "Articles of Incorporation" were finalized, and shortly after, all the legal documents were signed, sealed, and delivered. Initially there was some resistance, but before long, enough shareholders signed up to make the venture doable. In August 1953, ground was broken and construction began. November 20, 1954 saw the first residents move into the building. Construction and finishing work continued on the higher floors until February 1955, when all fourteen floors were completed and gradually occupied. Commercial space was rented, and eventually the entire structure became a vital, exciting, self-contained community.
