California is home to some of the wealthiest communities in the United States, but one town stands above the rest in 2025: Atherton. Nestled in the heart of Silicon Valley, Atherton has once again secured its reputation as the richest locale in the entire state, outpacing other exclusive enclaves with staggering household incomes and sky-high real estate values.
Atherton: Silicon Valley’s Crown Jewel
Atherton’s allure is rooted in its unique blend of privacy, prestige, and proximity to the world’s tech giants. With a population of just under 7,000, the town is home to executives and entrepreneurs from companies like Facebook, Google, and Apple. The average household income in Atherton now exceeds $619,000, while the median household income is well above $250,000.
What truly sets Atherton apart is its real estate market. Home values have soared to breathtaking heights, with median home prices ranging from $7–8 million and some properties selling for as much as $12 million in early 2025. These estates are typically situated on expansive, one-acre lots, shielded by lush landscaping and strict zoning laws that preserve the town’s exclusive, residential character.
Strict Zoning and Community Character
Atherton is famous for its deliberate lack of commercial zoning. There are no restaurants, shops, or commercial centers within its borders. This policy, along with the minimum lot size requirement known as the “Atherton acre,” ensures a tranquil atmosphere and limits access to only those who can afford its high price tag. Even recent state laws designed to increase housing density have had little effect, as newly created homes still command prices in the $8–9 million range.
Financial Strength and Premium Services
The town’s wealth is not just reflected in its homes but also in its services. Approximately 70% of Atherton’s general fund revenue comes from property taxes, allowing the town to maintain its own police department and immaculate public spaces without relying on commercial tax revenue. This financial independence further cements Atherton’s status as a haven for the ultra-wealthy.
How Atherton Compares to Other Wealthy California Towns
While other affluent communities like Hillsborough, Los Altos Hills, and Ross also boast high incomes and luxury real estate, none match Atherton’s combination of average income and exclusivity. For example, Hillsborough has a median household income above $250,000 and median home prices around $5–6 million, while Los Altos Hills and Ross also feature large estates and strict zoning but do not surpass Atherton’s financial metrics.
