10 most expensive ZIP codes in the U.S. in 2022

For the third consecutive year, Atherton, California, is the most expensive ZIP code in the U.S. to own a home.

Homes in the exclusive Bay Area town sold at a median cost of $9 million in 2022, expanding 0.56% from 2021, as per an analysis by online realtor RealtyHop. The first-place ranking returns three years to when the annual rankings were first followed.

Close to Stanford University, and home to tech executives and venture capitalists, Atherton has opposed the improvement of multifamily properties, which has kept homes large and exclusive.

In second place is Sagaponack, New York, a territory of a few hundred residents in the Hamptons, followed by the posh Bel Air neighborhood in Los Angeles. Third place is maybe the most famous ZIP code in the U.S.: 90210 — the namesake of the ’90s teen melodrama “Beverly Hills, 90210.”

The median home cost for the 100 most expensive ZIP codes was $2,749,500 in 2022, an increment of 11.03% from last year, the study says.

To accumulate the rankings, RealtyHop took a gander at costs for all types of homes in all ZIP codes in the country, between Jan. 1, 2022, and Oct. 19, 2022. Listings with invalid ZIP codes, including single-building ZIP codes, were prohibited.
