The most expensive ZIP code in America is a Miami island you can only reach by yacht or ferry

Happiness isn’t for sale. But for the ultrawealthy, a gated community with world-class homes and amenities might be the next best thing.

Realtor.com ranked the 10 most expensive ZIP codes in the US, focusing only on areas with at least 30 active listings. The top 10, concentrated in California, Florida, and New York, carry a median asking price of nearly $6 million — roughly the cost of 209 brand-new 2025 Toyota Camrys.

At the very top is 33109, home to Miami Beach and Fisher Island — a private enclave accessible only by yacht or ferry. The island has its own private school, gourmet market, clinic, golf course, beach club, and numerous tennis courts. Several celebrities, including Mel Brooks, Julia Roberts, and Oprah, have owned homes there. The price of entry is steep: Realtor.com reports the ZIP code’s median listing price is $12 million.

Jill Eber, a Coldwell Banker agent representing the sale and a resident of Fisher Island since 2000, told Business Insider the island’s lifestyle justifies the price tag.

“I think it’s one of the most beautiful places in the world, and its privacy, security, beauty, and amenities are unmatched,” Eber said. “You can’t get on the island unless you live there, or somebody leaves your name. It really feels like you’re on this amazing oasis in the middle of Miami.”
