I’ve analyzed the Zillow Home Value Index data to explore the most expensive residential property markets in California. The findings reveal extraordinary growth patterns across California’s premium real estate markets over the past fifteen years, with some towns experiencing value increases of over 200% since 2010.
What struck me most was the dominance of Silicon Valley and the San Francisco Bay Area in the rankings, with Santa Clara County alone accounting for six of the top 25 towns. The tech industry’s influence on California real estate values cannot be overstated, with towns like Cupertino (home to Apple) showing the highest growth rate at an astonishing 240.8% from 2010 to 2025.
Another fascinating trend is the acceleration of growth in coastal luxury enclaves during the post-pandemic period. Towns like Rancho Santa Fe and Montecito have seen their values surge by over 77% just between 2020 and 2025, significantly outpacing their historical growth patterns. This suggests a profound shift in high-net-worth housing preferences toward exclusive, low-density communities with abundant natural amenities.
