Its main clubhouse and other facilities were added to the National Register of Historic Places as the Southside Sportsmens Club District in 1973, and are today contained within the Connetquot River State Park Preserve.

The first article of the constitution of the association stated, "This club is established for the protection of game birds and fish and for the promotion of social intercourse among its members."

The South Side Sportsmen's Club promoted many of the laws protecting game not only on Long Island but throughout the state.

Members and their guests used the residence when visiting for fishing, sporting clays and other types of outdoor recreation.

Currently the building houses the New York State Regional Environmental Education Office and Interpretive Center, historic exhibits and Outdoor Learning Laboratory of BOCES Scope.
