News told by money
Seven of the 10 most expensive zip codes in the United States are in California, which probably comes as no surprise to many Californians.
But the most expensive zip code in the country, 33109, is located on Fisher Island, just a stone’s throw from Miami Beach.
A new ranking of the top 100 ZIP codes, measured by home sales price, reaffirms the pedigree of Silicon Valley, Newport Beach and the Hamptons. But most of all, it shows that waterfront addresses are here to stay.
Fisher Island, an ultra-luxury enclave that cannot be reached by car, had a median home sale price of $9.5 million in the first nine months of 2025, according to PropertyShark rankings.
The second highest zip code, 94027, is located in Atherton, California, a Silicon Valley community home to tech giants. Just a year ago, it was the most expensive ZIP in the nation.
America’s most expensive zip codes: Is it all about water?
Rounding out the top 10: zip codes in the Hamptons and California’s Newport Beach, Santa Barbara, Los Altos, and Marin counties. All addresses are on or near the coast.
“The list isn’t just about water, but many of the most expensive ZIP codes are in coastal and island locations,” said Doug Ressler, manager of business intelligence at Yardi Matrix, a sister company of real estate data website PropertyShark.
Newport Beach in Orange County, California ranks as the most expensive city in this ranking, with all residential zip codes in the top 100.
Only 15 states had at least one zip code in their rankings. As the report notes, the most expensive housing markets are “overwhelmingly coastal.”
Real estate values continue to rise on parts of the coasts of California, New York, and Florida, even though sea levels are also rising.
Ressler said climate risks are “becoming increasingly recognized” but “are not yet fully reflected in real estate prices.”
