International House
Why it's listed
International House is a ten-story residence hall and program center at 500 Riverside Drive in Manhattan's Morningside Heights, looking onto Sakura Park. Opened on September 15, 1924, it was designed by Louis Jallade in the Renaissance Revival style, with limestone and gray brick walls, a rusticated base, classical cornices and a monumental round-arched entrance. Its origins lie in Harry Edmonds' work with foreign students, which grew into a plan for men and women of all nationalities to live together. John D. Rockefeller, Jr. financed construction, and Abby Aldrich Rockefeller took a close interest in the design of its public rooms. The building became the model for International Houses in Berkeley, Chicago, Paris and elsewhere. It is recognized for its role in international education, its Rockefeller connections, and its intact institutional architecture. It continues to house graduate students from around the world, and its main lounge and reception rooms keep their classical detailing.
Significance in brief: The nomination argues it was the prototype for later International Houses in the United States and abroad, advancing international education and cultural understanding. It is tied to John D. Rockefeller, Jr. and Abby Aldrich Rockefeller, who financed and closely guided its creation. It is also a largely intact example of early-twentieth-century institutional architecture in the Renaissance Revival style.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
