After garnering a No.1 ranking last year, Miami Beach’s Fisher Island was knocked down to third place in PropertyShark’s annual ranking of the 100 most expensive ZIP codes in the United States.
The new champ is 94027 in Atherton, California, also known as the “billionaire capital of Silicon Valley,” according to real estate research company PropertyShark. Home to former Google CEO Eric Schmidt, former Meta COO Sheryl Sandberg and Netscape cofounder and venture capitalist Marc Andreessen, the ZIP code set a new record by breaking the eight-digit barrier with a median sales price of almost $11 million.
PropertyShark ranked U.S. ZIP codes based on registered residential transactions closed between Jan. 1 and Sept. 30. States with non-disclosure rules including Montana, Texas, Utah and Wyoming were excluded due to lack of data.
Sagaponack’s 11962 ZIP code in the Hamptons on New York’s Long Island ranked No. 2 with a median sales price of $7.35 million.
Generally, coastal ZIP codes performed well, and Fisher Island was no exception.
“Following last year’s unexpected turn at the very top, Fisher Island’s 33109 returned to a more typical position following a 24% Y-o-Y price cut,” said PropertyShark senior writer Eliza Theiss. “Still, its $7.22 million median sale price was its second-highest yet and marked its ninth appearance among the country’s 10 leading ZIP codes since 2016, where it typically ranks third or fourth.”
The only other Florida ZIP code to make the list was Boca Grande’s 33921 on Gasparilla Island, which made its third appearance in the top 100 at No. 36 with a median price of $3.3 million.
“As always, the country’s leading zip codes were characterized by coastal proximity,” Theiss wrote. “Of the 122 zips making up the top 100 (the result of multiple price ties), 72 are located within five miles of the coast and 39% are less than one mile away. In fact, only five locations are more than 25 miles from the ocean.”
