The home of some of the country\u2019s most prominent tech companies is also home to the most expensive residential real estate in the nation.<\/em><\/p>\n

Silicon Valley continues to see increased demand for high-end single-family homes, with zip code 94027 in Atherton, CA standing out as the area\u2019s most expensive place to buy. In fact, according to San Francisco Curbed<\/a>, 7 out of the 71 billionaires who reside in the Bay Area have a primary residence in Atherton.<\/p>\n

To see which Silicon Valley zip codes attract the most affluent buyers, we went through the 2014 sales data and we\u2019re ready to reveal the area\u2019s 20 most expensive zip codes<\/strong>.<\/p>\n

\"The<\/p>\n

The 20 most expensive zip codes in Silicon Valley were either in Santa Clara<\/strong><\/a> or San Mateo<\/a><\/strong>\u00a0counties: 12 were in San Mateo, while 8 were in Santa Clara. The area’s real estate is on fire thanks to top sales<\/a> in towns like Palo Alto, Woodside, Los Altos and Atherton.<\/p>\n

Zip code 94027 in Atherton clinched the top spot with a median sale price of $3,900,000.<\/strong>\u00a0The swanky town in the heart of Silicon Valley is a unique community \u2013 a perfect blend of thoughtfully designed neighborhoods, beautiful mansions, gorgeous natural settings, top-rated schools, and first-class amenities.<\/p>\n

The location is one of the big draws of Atherton. Just a stone\u2019s throw away from Menlo Park and Palo Alto, which many tech giants call home, including Facebook, Google, Oracle, and Apple, Atherton offers residents\u00a0a convenient commute. Another advantage it has over other prestigious locations is its relatively relaxed building regulations, according to Forbes<\/a>, which ranked Atherton’s 94027\u00a0 zip code as the most expensive not only in California but in the entire country. The exclusive residential enclave is home to several of the tech industry\u2019s top executives<\/a>, including Microsoft co-founder Paul Allen, Google chairman Eric Schmidt, and HP CEO Meg Whitman.<\/p>\n

Two\u00a0zip codes in Los Altos Hills \u2013 94022 and 94024 \u2013 took second and third positions respectively<\/strong>. A beautiful mix of rolling hills and picturesque valleys, Los Altos Hills holds some of the most attractive and best-valued properties<\/a> in The Peninsula. Homes in both zip codes increased 17% from 2013: 94022 had a median sale price of $2,450,000 while 94024 saw the median sale price hit $2,200,000 in 2014.<\/p>\n

Zip code 94024 was closely followed by 94301 in Palo Alto<\/strong> which registered the same\u00a0median sale price – $2,200,000. However, the median sale price of the latter grew by an astounding 50% year-over-year, up from $1,470,000 in 2013.<\/p>\n

In fact, the city known as the “Birthplace of the Silicon Valley\u201d saw some of last year\u2019s biggest residential transactions<\/a>, including the sale of a superb estate at 215 Lowell Avenue in Palo Alto<\/a> which changed hands for $19,880,000.<\/p>\n

Median sale prices in the the top 20 zip codes went up, except for\u00a094025 in\u00a0Menlo Park<\/strong> where the median sale price remained flat year-over-year \u00a0($1,350,000 in 2014, unchanged from 2013) and\u00a094028 in Portola Valley<\/strong> which saw a 4% drop in median sale prices.<\/p>\n

Here is the complete list of Silicon Valley\u2019s top 20 priciest zip codes:<\/p>\n
