Nationally, Florida’s Fisher Island (ZIP 33109) dethroned Atherton, CA, as the most expensive ZIP code in the U.S. with a median sale price of $9.5 million, up 65% year-over-year; this is the first time Florida has secured the #1 spot. California remains dominant overall, with eight of the top ten ZIP codes and 61% of the overall top 100 ZIP codes.

Newport Beach was noted as the most expensive city, having all six of its ZIP codes in the top 100. The Bay Area still has the most luxury ZIP codes overall but continued to see a contraction in its luxury market.

About the ranking

The PropertyShark ranking is in its 10th year and focuses on closed-sale data for a more accurate view of luxury real estate in the U.S. The 2025 edition emphasizes shifting dynamics in regional luxury housing markets, particularly in New England, where island and suburban markets can diverge sharply from urban trends.

What this means for readers

Buyers, sellers and market watchers should note that the ranking reflects completed transactions rather than listing intentions, and that high median sale prices in a ZIP code can be driven by a relatively small number of high-value sales. The Massachusetts presence in the top 100 underscores continued demand for a mix of coastal, urban, and suburban luxury properties even as some markets adjust from pandemic-era peaks.
