Today we’ll share the market reports for three Silicon Valley Counties. These are from December 2022.
Santa Clara County, San Mateo County, and Santa Cruz County are the areas covered below. Generally, “Silicon Valley” is 95% within Santa Clara and San Mateo Counties, plus a little of Santa Cruz County and a small part of Alameda County. Alameda County uses a different MLS system, and we don’t usually sell there, so we are not covering it in this post.
Each section below includes first the data for single family homes and then condos and townhomes for each region.
If you’re ready to dive a little deeper, we also provide regular monthly market updates on some of the popular communities within Santa Clara County over at my Valley of Heart’s Delight blog. Scroll the most recent ones here.
December 2022: Three Silicon Valley Counties
Santa Clara County Real Estate Market Report for Dec 2022
The first of the three Silicon Valley counties is Santa Clara County – home to San Jose, Cupertino, Sunnyvale, Mountain View, Palo Alto, Los Altos, Santa Clara, Campbell, Los Gatos, Saratoga, Monte Sereno, Milpitas, Morgan Hill, and a number of other cities and towns. This county is the heart of Silicon Valley.

The market is clearly cooling with longer days on market, fewer sales, and a falling median sales price.
The condominium and townhouse report for Santa Clara County
While it had fewer than half the sales of the single family home market, the condo and townhouse market is also experiencing similar trends.

If you’re relocating to the San Jose area, there are a few tools you can use for resources as you evaluate different parts of the region. When I started this website, I had books listed that you could purchase. Today, mostly I have websites that you should bookmark – for free!
Natural & Environmental Hazard Information Tools You Can Use
Natural hazards are found throughout the United States, often the major one people consider is the one hundred year flood plain. Here in the Golden State, we have some additional concerns relating to fire and earthquake risks.
- California MyHazards can display a map anywhere in the state with information relating to liquefaction zones, earthquake faults, 100 year flood plains, and high fire risk areas. (The info for the very high fire hazard severity zone has not been updated, so use the Cal Fire map for that info.)
- Cal Fire map for all of California with the high fire severity zones shown – zoom in to find the areas of concern
- Flooding from Dam Failure (potentially caused by earthquakes as well as other possibilities) is scary. Learn more about those zones at the link I’m providing here. (As of this writing, the Approved Inundation Maps link is not working.)
A Barclay’s Locaide
will outline earthquake faults, flood plains, and other natural hazard zones you might want to know about. This is now out of date, but you may be able to locate a used one online or see if a local real estate association of Realtors bookstore has it available.
Something else to know is that there are state mapped earthquake faults (the more active ones, such as the Hayward or San Andreas Fault) and also the city, town or county mapped fault zones (for example, the Shannon Fault). The latter may have been dormant for 11,000 years or more.
Buying a home? Sellers usually provide a Natural Hazard Report, an Environmental Hazard Report, and a Tax Report from a company such as JCP
. This same company / site has a great amount of information on local conditions on its About the Hazards
page that newcomers would benefit from.
When buying a home in California, consumers are given a link to download brochures, or one combined document, on a variety of hazards. I’m not sure that most of them take the time to read it, but it’s excellent info and I highly encourage anyone living in CA, whether renting or owning, to read it:Homeowner’s Guide to Earthquake Safety & Environmental Hazards
Environmental Hazard Zones: Research Tools You Can Use
- Local concerns also include environmental ones, such as Superfund sites.
- Some sites with spills, leaking underground storage tanks, or other issues can be found at this Cleanups in my community page (nationwide info)
- Mercury, or quicksilver, was mined in Almaden (New Almaden and related mines) and east Los Gatos (Guadalupe Mine area) – it is a naturally occurring element in cinnabar. For that reason, creeks in those areas should not be entered or fished in. It can be found in other creeks and rivers, too, but primarily in Almaden.
- Asbestos is another naturally occurring element here. It was prized for being somewhat fire resistant and was mined under Communications Hill. It’s something to investigate if you want to live in that area.
- Oil, gold silver, and other elements were mined here as well as granite (we still have quarries active in Santa Clara County today, a couple in the Cupertino area and one in the hills by Lexington Reservoir just outside of Los Gatos). Some old mines are not mapped if they are on private land, so one of the disclosures we have relates to unmapped, abandoned mines., which may be found in more rural pockets of the county.
- Flooding from dam failure (dams are human made, hence it’s not a “natural” hazard ) is a risk in a large part of Silicon Valley. Most of the areas at risk from flooding due to dam failure are listed on this site.
- Noise pollution: use either How Loud or Noise-Map. We discussed the pros, cons, and shortcomings of these on our main blog: Measuring Noise Pollution.
Other Priorities for the Tools You Can Use list
In addition to natural and environmental hazards, there are big plusses that will attract new residents.
It is also helpful to have a knowledgeable Realtor as your resource! Please call me if you’d like assistance in your move to SIlicon Valley. I’d be happy to help you.

Today we’ll provide a few quick graphics to give you a Silicon Valley pricing snapshot on the 4 counties where we sell homes. These will be ranked by order of housing cost, from highest to lowest. After that, we’ll provide more resources from our other sites and blogs with a deeper dive on our main Silicon Valley real estate markets. We don’t cover all 9 of the San Francisco Bay Area counties, but here you’ll find 3 of them covered, and it’s a pretty good primer on the Bay Area housing market analysis.
Silicon Valley Pricing Snapshots
San Mateo County
San Mateo County is “The Peninsula”, the county just south of San Francisco and north of Santa Clara County and Santa Cruz County. About a quarter of Silicon Valley is in this area, generally.
For three of these counties, we have a newsletter with info by city.
Santa Clara County
Santa Clara County, our home base, is the second priciest area in this region and is the heart of Silicon Valley:
And the city by city market stats:
We also do monthly market updates on communities within the Santa Clara County and more on our other blogs. Check out some of those market reports through the link.
Santa Clara County is home to a number of Superfund sites. Where are they?
A helpful, free website that anyone can use is EnviroStor. From the home page you can take a tour on how to learn about Superfund and other environmental hazards in California. The image below is showing only the Federal Superfund – please note in the left column that just the first box is checked. If you are particularly interested in school cleanup or school investigation, you’ll want to check those boxes. (The image is linked to the EnviroStore page fyi.)
There are quite a few Superfund sites concentrated in Santa Clara, Sunnyvale, and Mountain View, but they can be found in San Jose, East Palo Alto, Scotts Valley, Cupertino, Palo Alto, and more areas in Silicon Valley.
People coming from out of the area to relocate to Silicon Valley might not know what to expect from the weather in the San Jose, Santa Clara County, or Silicon Valley Area. Does this part of California ever rain? How hot is the summer? What is the climate like?
In a nutshell, this is a “sub-tropical” area, or a place that enjoys a mild “Mediterranean climate” that is most heavily influenced by the close proximity of the shoreline and the Pacific Ocean. Temps are mild, we get little rainfall compared to many parts of the country.
More specifically, we usually get about 10-20 inches of rainfall a year (less on the east and more on the west) and enjoy as many as 300 sunny days a year. Winters seldom see many hard freezes (but they can happen).
A typical summer day has highs in the mid to upper eighties but very low humidity – so it feels much cooler. Heat waves and heat inversions can run the temps up to the low to mid 100s in the hottest parts of the valley. Luckily it doesn’t happen much, or stay for long! Once in awhile, a rare storm in summer will bring high humidity and thundershowers, but for the most part, summers are dry. The hottest month is typically August.
The coldest month, usually, is December. A January day will often have a high in the 60s or 50s, depending. A cold day here is when it does not get into the 50s (not too common). By February, though, the worst is usually over and it’s even possible to have freak warm days that hit 80 degrees!
Our weather varies from year to year. Some years we get drought conditions and may require water rationing . Other years we get lots of wet weather from the Pacific – temps are warmer but there’s much too much rain: those are the El Niño years. Most often, though, winters aren’t that bad – evenings can be nippy as temps drop into the 20s on the worst nights in December or January. It will make the news that people should cover their citrus trees so they aren’t damaged by the freezing temps. (more…)
