The average size of a newly constructed home in the United States has more than tripled over the last 75 years, from 797 square feet in 1945 to 2,491 square feet in 2020.

The glut of large homes in the United States has also created a supply issue in the real estate market, with a surplus of large homes nobody wants to buy.

So before you book your next vacation, it may be worth reviewing the largest home in every U.S. state.
We curated lists of the largest houses in each state by compiling results found in blog articles and online listings such as Family Handyman, HomesOfTheRich, and PriceyPads. We also collated information from local newspaper articles.
We then confirmed that each building cited was indeed currently used as a residence. To fill in any research gaps, we sorted state listings on Zillow (in the “sold” and “for sale” categories) by square footage to find the largest single-family residence in that state. Where conflicting information was found, we chose the most frequently quoted record, the record from the most reliable source, or the most specific record (i.e., 72,215 ft2. rather than 72,000).
We searched each address in Google Maps on satellite view, preserving a screenshot of the home’s footprint. If Google maps could not find the specific address, we searched the road in question until we found a home whose footprint matched the appearance of the real estate listing. If the image available was blurry, we tried to find additional images of the home to share. Other images were pulled from real estate listings, Google Image search, or news sources.
The data was collected in Feb 2022.
