The Largest Residential Home in Every U.S. State

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. Cheap building materials, easy credit, and single-use zoning have led to Americans having more floor area per resident of any country and left the U.S. with an abundance of large homes.

To see just how large some Americans live, researchers at Angi found the largest single-family homes in every state. This collection of megamansions highlights a diverse array of architectural styles, historical landmarks, and pockets of extreme wealth across the country.

Key Findings

• ‘Fair Field’ is the largest home in the state of New York— and in the country. At 110,000 square feet it is twice the size of the White House.

• The largest home in the state of Washington is ‘Xanadu 2.0,’ a 66,000-square-foot lakefront lodge built by Bill Gates in 1995.

• Searles Castle is one of the largest castles in the country, and the largest private residence in Massachusetts, offering 54,246 square feet of living space.

• The smallest-largest home resides in South Dakota and could fit inside ‘Fair Field’ nine times. The 11,734 sq. ft mansion boasts four bedrooms, eight bathrooms, and a private exercise room.

The Largest Home in New York, and the Country, Is Twice the Size of the White House

While some of the country’s largest homes are historic homes listed in the National Register of Historic Places, a majority of megamansions were built in the last several decades. The largest home in Virginia, for example, was built in 1776 and has remained relatively unchanged from its original design. Meanwhile, the largest home in Maryland was built as recently as 2017.

The Biggest Home in Each State, Ranked by Size

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. As the baby boom generation ages into retirement and downsizes their living spaces, transitioning from homeownership to retirement rental units, there are not enough potential homebuyers to fill their space.

As a result, many of the largest homes in America have been on the market for years, gradually depreciating in value as their owners slash millions from their asking price. For example, the mammoth Bel Air mansion known as “The One” sold in March 2022 for $141 million, less than half its $295 million asking price. McMurry Mansion in Casper, Wyoming, sold for $5 million in December 2021, far below its $25 million asking price.

So before you book your next vacation, it may be worth reviewing the largest home in every U.S. state.

Methodology

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.
