Where Silicon Valley’s $5 Million Houses Sell, Neighborhood by Neighborhood (2026)

Where do Silicon Valley’s $5 million houses sell? In the two years to October 27, 2026, 20,134 single-family houses sold in the 27 cities and towns of Santa Clara and San Mateo counties where we have neighborhood guides and a full city data series. 4,663 of them (23%) sold for $3M or more, 1,036 (5%) for $5M or more and 75 for $10M or more. Here is where, city by city and in the neighborhood guides with the most, and how the count of $5M+ sales has grown since 2012.

The short answer

• Not counted in these rankings: Atherton, Woodside, Portola Valley and Hillsborough, where much of the region’s top end sells. By their own posts’ count, in the same two years they had 378 more house sales at $5M or more (including Hillsborough 169 and Atherton 111) and 118 at $10M or more, more than the 75 in all 27 cities and towns here. They have neighborhood guides but no full city data series; their own posts (Atherton, Woodside and Portola Valley; Hillsborough) count $5M+ and $10M+ sales over five years.
• Of the 27 cities and towns here, the most $5M+ house sales were in Los Altos & Los Altos Hills (381, 53% of its house sales), Palo Alto (208, 28% of its house sales) and Menlo Park (123, 23% of its house sales).
• Neighborhoods with the most: North Los Altos (82), Central Menlo Park (59) and Central Los Altos (58).
• Highest share (guides with at least 10 house sales): Arastradero Road & Manuella in Los Altos Hills (12 of 13), Page Mill Road & Palo Alto Hills in Los Altos Hills (17 of 20) and Shadow Oaks in Saratoga (11 of 13).
• $10M and up: 75 sales; 28 guides had at least one, and Old Palo Alto (17) had the most.
• Growth: 24 houses sold for $5M or more in 2012 and 482 in 2025, and 429 in the first nine months of 2026 alone (prices aren’t adjusted for inflation).

City by city

Single-family houses sold in the two years to Oct. 27, 2026, most $5M+ sales first. Each city opens its own luxury post, which uses price levels set for that city. No house sold for $5M or more in Daly City, East Palo Alto, Foster City, Gilroy, Millbrae, San Bruno, Santa Clara and South San Francisco, though Santa Clara (36), Millbrae (18), Foster City (11) and Gilroy (10) had sales at $3M or more.

The 26 neighborhoods with the most $5M+ sales

Guides ranked by the number of house sales at $5M or more in the two years to Oct. 27, 2026 (ties alphabetical). Each name opens its neighborhood guide.

$10 million and up

Every guide with a house sale at $10M or more in the two years: Old Palo Alto (17), Arastradero Road & Manuella in Los Altos Hills (6), Central Menlo Park (6), Crescent Park in Palo Alto (5), Town Hall & Fremont Road in Los Altos Hills (5), Sharon Heights in Menlo Park (4), Altamont, Taaffe & Moody Roads in Los Altos Hills (3), Barron Park in Palo Alto (2), Burke Road & Sunset Drive in Los Altos Hills (2), El Monte Road & Foothill College in Los Altos Hills (2), Mora Drive & Olive Tree in Los Altos Hills (2), Saratoga Foothills (2), Shannon & Kennedy Road hills in Los Gatos (2), Allied Arts / Stanford Park in Menlo Park (1), Burlingame Park (1), Central Los Altos (1), Community Center in Palo Alto (1), Costello Acres in Los Altos (1), El Sereno Hillside in Monte Sereno (1), Esther Clark Park in Palo Alto (1), Montalvo & Horseshoe in Saratoga (1), Monte Sereno (1), Montebello Acres in Los Altos (1), Parker Ranch in Saratoga (1), San Mateo Park (1), Santa Rita in Los Altos (1), Sobey & Marshall Lane in Saratoga (1) and University South in Palo Alto (1). Some of the 75 sold outside every guide, and a sale inside two overlapping guides counts in both.

$5M+ house sales by year

House sales at $5M or more across the same 27 cities and towns each year since 2012 (MLS records we can read; through 2018 our records hold essentially one MLS’s sales, so those years’ counts, especially of all house sales, may be a little low).

San Francisco, for comparison: 261 of its 4,562 house sales in the same two years were $5M or more and 40 were $10M or more; San Francisco by guide.

Reading it right

• Size drives much of the top end, so compare price per square foot as well as price.
• These are sale prices, not list prices, and they aren’t adjusted for inflation.
• Houses only. Condos and townhomes have their own posts in each city series.
• Small samples swing. Every row shows its sale count.
• Some guides overlap, and a sale inside two outlines counts in both, as in the city posts.
• Past sales aren’t a forecast or the value of any one home.

How we counted

Closed sales of single-family houses in the two years to October 27, 2026, reported to the MLS and read through the IDX feeds that power our home search, with repeat records removed and only sales with a recorded living area and a map position, placed inside each neighborhood guide’s outline. These are the same sales, and the same rules, as each city’s own budget and luxury posts; where a city post uses one of the price levels here, its neighborhood counts are identical.

Go deeper

The Luxury Market Report tracks $3M+ sales and listings city by city, and the Price Ladder shows entry, median and top-end prices. Across every city we cover, neighborhood by neighborhood: price per square foot, sale vs. asking, ten years of price change, where houses still sell under $2M and condo and townhome prices. Every city’s data posts are on one page.
