April 2026 Silicon Valley Housing Market Report: A Tale of Two Markets

April was the month Silicon Valley's housing market stopped easing into spring and started running. Both San Mateo and Santa Clara Counties posted their busiest April of the year so far, with sales volume up sharply and inventory tightening even as new listings continued to hit the market. The headline numbers are clean. The story underneath them is more interesting.

What looked like one market in March split into two distinct ones in April. At the top of the Peninsula, in Atherton, Hillsborough, Los Altos, and Menlo Park, confident buyers competed aggressively, often with multiple offers and frequent overbidding. In the mid-market, from $1.5M to $3M, the texture was more measured. Buyers showed up, but they took their time, asked more questions, and wrote sharper offers. Two real markets, in the same zip codes.

Did Silicon Valley Home Sales Reaccelerate in April 2026?

Yes. April 2026 closed sales were up 33% in San Mateo County and 18% in Santa Clara County compared to March. The Peninsula recorded 1,251 single-family closings across the two counties, with combined sale volume of $3.35 billion in a single month.

Inventory tightened even as sales accelerated. San Mateo County dropped from 2.0 months of supply in March to 1.5 months in April. Santa Clara County held near 1.5 months. Days on market in Santa Clara fell from 19 to 16. Buyers who waited out the late-winter lull are now competing with each other, and well-prepared listings are still going pending in roughly two weeks.

The list-to-sale price ratio tells the same story. Across San Mateo County, the average home sold at 107% of list price. Across Santa Clara County, the average was 105%. Within those averages, several individual cities saw buyers paying double-digit premiums above asking.

How Did San Mateo County Perform in April 2026?

San Mateo County had a strong April. The single-family median sold price was $2,167,500, essentially flat from March's $2,177,500. The average sold price climbed slightly to $2,914,748. Closed sales jumped 33% to 416 transactions, and total sale volume reached $1.21 billion, also up 33% from March.

The county's 1.5 months of inventory means the supply-demand balance tightened despite 470 new listings hitting the market. That is a structurally healthy sign: sellers are listing, but buyers are absorbing inventory faster than it arrives.

City-by-City: Where Buyers Competed Hardest

The county-wide median masks meaningful differences across cities. April's standouts:

• Burlingame: $3.17M median (25 sold), 105% of list, just 9 days on market and 0.8 months of inventory. The fastest-moving city in San Mateo County.
• San Mateo: $2.38M median (52 sold), 113% of list, 0.9 months of inventory. The strongest list-to-sale ratio on the entire Peninsula. Buyers paid 13% above asking on average.
• Menlo Park: $3.79M median (32 sold), 103% of list, 11 days on market. Median up 8% from March, and the city posted its strongest closed-sales count of the year.
• San Carlos: $2.75M median (28 sold), 106% of list, 12 days on market. The median pulled back from March's $3.17M as the mix shifted toward smaller homes, but the pace of sales remained brisk.
• Hillsborough: $8.0M median (15 sold), 97% of list, 16 days on market. Activity rebounded sharply, with closings up 50% from March's 10.
• Atherton: $9.63M median (10 sold), 99% of list, 43 days on market. The median dropped from March's $14.8M because the mix of closings shifted toward newer-construction and smaller-lot homes.
• Foster City: $2.48M median (2 sold), 108% of list, 1.3 months of inventory.
• Redwood City: $2.17M median (63 sold), 108% of list, 13 days on market. The largest volume of single-family sales in the county.
• Belmont: $2.36M median (22 sold), 106% of list, 12 days on market. A textbook fast-moving mid-Peninsula market.

The common thread across San Mateo County in April: every major city had less than two months of inventory, and homes priced with discipline continued to attract multiple offers within the first ten days.

Days on market data show why pricing strategy matters. The county-wide average was 19 days, but that average is pulled up by a small number of estate-quality homes that sit longer. The middle 80% of homes, those between $1.5M and $5M, generally sold inside two weeks.

What Happened in the Santa Clara County Housing Market in April 2026?

Santa Clara County had its strongest April in three years. The single-family median sold price was $2,100,000, up 1.0% from March's $2,080,188. The average sold price climbed 2.3% to $2,555,780. Closed sales jumped 18% to 835 transactions, and total sale volume hit $2.13 billion, up 20% from March.

Days on market improved meaningfully, falling from 19 to 16. The list-to-sale ratio held at 105%, very close to March's 106%. The story here is volume rather than price acceleration. Buyers came back to the market in numbers, and homes priced correctly continued to move.

Single Family Homes: City Breakdown

The single-family market in Santa Clara County recorded 1,206 new listings and 835 closed sales in April. Several cities posted notably strong months:

• Los Altos: $5.02M median (35 sold), 109% of list, 13 days on market. The volume leader at the high end of the county. Closings were up 35% from March.
• Palo Alto: $4.13M median (48 sold), 107% of list, 15 days on market. The largest volume of high-end transactions in the county.
• Sunnyvale: $2.54M median (66 sold), 109% of list, 11 days on market. The largest volume of single-family sales among mid-tier cities.
• Mountain View: $3.27M median (26 sold), 107% of list, 11 days on market. Demand near Google and OpenAI's expanding campuses remained strong.
• Cupertino: $3.24M median (22 sold), 110% of list, 11 days on market. The school district premium continued to drive aggressive bidding.
• Saratoga: $4.25M median (25 sold), 103% of list, 15 days on market.
• Los Altos Hills: $4.92M median (8 sold), 96% of list, 26 days on market. One of the few segments selling below list, reflecting the longer-cycle nature of estate properties.
• Santa Clara: $2.10M median (39 sold), 108% of list, 19 days on market.
• San Jose: $1.70M median (412 sold), 105% of list, 16 days on market. San Jose alone accounted for nearly half of all single-family closings in the county.

The Condo and Townhome Market

The condo and townhome segment in Santa Clara County continued to offer relatively more breathing room for buyers. With 601 new listings and 319 closed sales, the median price was $1,100,000 with a 102% list-to-sale ratio and an average of 32 days on market.

The gap between condo and single-family performance widened slightly from March. Single-family homes are selling at 105% of list in 16 days; condos are selling at 102% in 32 days. For buyers willing to consider attached housing, the math still favors them in ways that the single-family market does not:

• Sunnyvale condos: $1.37M median (37 sold), 104% of list
• Mountain View condos: $1.43M median (27 sold), 104% of list
• Palo Alto condos: $1.18M median (13 sold), 101% of list
• San Jose condos: $898K median (137 sold), 101% of list
• Los Altos condos: $1.89M median (9 sold), 98% of list. One of the rare segments where buyers had genuine negotiating power.

Why Did Atherton's Median Drop While Hillsborough's Rose?

Atherton's median fell from $14.8M in March to $9.63M in April. Hillsborough's median climbed from $7.15M in March to $8.0M in April. Both moves were driven by mix, not by underlying market weakness or strength.

In Atherton, March closings concentrated heavily in the $14M-to-$20M estate band, where homes on larger lots with mature landscaping commanded premium pricing per square foot. April closings included more newer-construction homes on smaller lots, and the median price per square foot was $2,126, lower than March's $2,274. The 43-day average days on market for April reflects the fact that several of the closings were homes that had been listed earlier in the year, not new spring listings selling in days.

In Hillsborough, the opposite dynamic played out. March's mix included a number of homes priced below $7M; April's mix shifted toward larger estate properties, pulling the median up to $8.0M. Closings rose from 10 to 15.

The takeaway for sellers in either city: in markets where 8 to 15 homes close in a month, a single transaction can move the median by hundreds of thousands of dollars. Use the month-over-month numbers as a directional signal, but rely on neighborhood-level comparable sales when pricing your home. The headlines move; the comps tell you what your specific property is worth.

Is Now a Good Time to Buy or Sell on the Peninsula?

For sellers, the answer is yes, especially in San Mateo County. With inventory at 1.5 months and homes selling at 107% of list price on average, sellers who price with discipline and invest in presentation are in an exceptionally strong position. April was the busiest month of the year so far, and well-prepared listings continued to attract multiple offers within the first ten days.

The right time to list is when your property is ready, the comparable sales support your pricing, and you have a clear plan for where you are going next. April's data confirms that the spring window is wide open through Memorial Day at minimum.

For buyers, the picture is more nuanced and depends heavily on price band. At the high end, in Atherton, Hillsborough, Los Altos, and Menlo Park, expect competition. Come prepared with pre-approval, strong contingency strategy, and a clear ceiling. In the $1.5M to $3M mid-market, particularly in cities like San Carlos and parts of Belmont, the texture is slightly less aggressive, and well-positioned offers can win without the maximum overbid.

The condo and townhome segment in Santa Clara County remains the most accessible path for first-time buyers. With 32 days on market and 102% list-to-sale ratios, buyers have meaningful leverage in cities like San Jose, Milpitas, and Los Altos that simply does not exist in the single-family market.

Both counties remain well below the 5-to-6-month inventory threshold that defines a balanced market. Until supply catches up to demand, sellers hold the structural advantage across Silicon Valley. April's data made that clearer than ever.

What to Watch Through Memorial Day

Three dynamics will shape the market through late spring.

Tech earnings and AI investment cycles. Nvidia, Apple, Google, and Meta report through May. Strong AI-related results have a direct, measurable impact on Peninsula luxury demand. Nvidia's recently filed plans for a third 700,000-square-foot headquarters building in Santa Clara, combined with the company's $35M acquisition of the 10-building research park on Walsh Avenue, signal that the AI corridor is expanding, not contracting.

New ADU rules. California's SB 543 and AB 462 took effect this year, dramatically shortening the timeline for ADU permit approvals. Cities now have 15 days to confirm an application is complete and 60 days to make a decision. For Peninsula homeowners weighing whether to add a backyard cottage or convert a garage, the approval clock is faster than it has been in a decade.

Inventory patterns. April's 1,676 combined new listings across both counties suggest that supply is responding to spring demand. If new listings hold pace through May, the supply-demand imbalance will moderate slightly, giving buyers marginally more leverage. If listings slow, expect the overbidding dynamic to intensify into summer.

The Silicon Valley housing market in April 2026 was not one story but two. The luxury end accelerated. The mid-market kept up. Both counties posted their strongest April in years. Both remain among the most competitive real estate markets in the country.

What matters most is how these macro trends translate to your specific street, your specific property, and your specific timeline. The numbers in this report are averages. Your home, your block, and your situation are not average. That is where local expertise makes the difference.
