Of course, "largest house" is a somewhat nebulous term so, to clarify: this list only takes from single-family,actualized—though do keep an eye out for NYC's 62,000-square-foot The Residence at River House, TBD—listings in the United States found on Zillow. Now what counts as a "single-family?" Also nebulous. Let's put it this way: a huge manor with a couple of guest houses on the property? Sure, the total compound's interior square-footage is counted here. A property that's got a house plus four guest villas, three stocked lakes, two guest houses, and a 70,000-square-foot equestrian center? Yeah, that's not a house, that's a summer camp.Nice try, bub.
