The Most Expensive U.S. Zip Codes in 2020

We at RealtyHop are constantly looking to uncover interesting trends from our data. While we’ve reported on a wide range of issues, including affordability, migration trends, and market health, we’ve never explored where the country’s most expensive housing markets are located. In this study, we pulled every real estate listing advertised in the United States so far this year, over 3.2 million, and sorted these properties by zip code. We finally ranked each zip code by median price, resulting in a comprehensive picture of the most expensive markets across the nation right now. Here’s what we found.

Key Findings:


  • 94027 in Atherton, California is the most expensive zip code in the country for real estate, with a median price of $8,650,000
  • The 100 most expensive areas are located in just 11 states
  • Los Angeles has 10 of the nation’s 100 most expensive zips, the highest of any city in the country
  • 41 zip codes have a median listing price of $2.5M or more
  • When looking by state, California has 68 of the 100 priciest zip codes, followed by New York with 20 zip codes


The 10 Most Expensive U.S. Zip Codes

Most won’t be surprised at the top ten most expensive zip codes on our ranking, given their prominence as exclusive communities. Atherton’s 94027, the most expensive zip code in the country at a median of $8,650,000, is located in the epicenter of Silicon Valley, and is well known to house the tech industry’s elite. Fisher Island, an exclusive enclave off the coast of Miami with only a few hundred households, has one of the highest per capita incomes in the country, and a median list price of $6,500,000.

And of course, Beverly Hills 90210 in Los Angeles is arguably the most famous zip code in the United States.

11 States Have Zip Codes in Our Ranking, Mostly Centered in California and New York


The nation’s priciest areas are found in only 11 states, with 88% located in California and New York. Outside of those zip codes in those two states, Fisher Island, Miami, was the highest at 2nd place overall, followed by Medina, Washington, a suburb of Seattle, at 12th. Greenwich, Connecticut, a wealthy suburb an hour outside of Manhattan, is the most expensive zip code in New England at 44th place.

Los Angeles is the Most Exclusive City in the Nation

Los Angeles commanded 10 of the top 100 most expensive zip codes in the country, making it the most exclusive city in the United States.

Beverly Hills (90210) was the top zip code, followed by Bel Air (90077), and the Pacific Palisades (90272).


Most Expensive Zip Codes in New York City

New York City also commanded some of the highest prices in the country, with 6 of the top 100 in its city limits. The top three zip codes in NYC were Soho (10013), TriBeCa (10007), and Chelsea (10001).



This report analyzed the most expensive zip codes in the United States using over 3.25 million for-sale listings drawn from the RealtyHop database during the period between January 1, 2020 and October 9, 2020. To produce the ranking, the median price for each zip code was calculated and sorted from most expensive to least.

The following building types were used to calculate median sales price: condo, coop, house, multifamily, residential, townhouse, and triplex. Any listings classified purely as “land” were excluded from the study. Any listings with invalid zipcodes were also excluded.
