How is Silicon Valley Different?Every so often I am asked how the San Jose – Silicon Valley area is different from other parts of the US for home buyers. What did they need to be concerned about here versus in the midwest or east coast? They knew about earthquakes, and having to strap water heaters for earthquake safety, but what about earthquake insurance? Are termites a problem here? What things should home buyers worry about here that perhaps are not issues elsewhere?

Silicon Valley Differences

This is a great question, and the answer to it could fill a book! But here are some of the major differences that most relocating buyers, especially those from out-of-state, should be aware of.

Natural Differences

    1. Earthquakes (of course) and everything related: selling requirements, insurance questions, related natural hazard zones (liquifaction zones, landslide areas, etc.), where fault lines are located, etc. People moving to California generally know that they need to be concerned about seismic occurrences, but perhaps not all the related areas.
    2. Expansive clay soils: when you read your history, you may have heard that in early California, homes were made of adobe bricks. What may not have been clear is how strong that soil is. I have a couple of blog posts on my Valley of Hearts Delight blog on this topic:

    3. Termites: in general, there are 2 types of these pests active on the valley floor: drywood termites and subterranean termites. (In the Los Gatos Mountains and closer to the Pacific Ocean you may also encounter dampwood termites.) It may be possible to try to prevent subterranean termites with bait stakes placed underground, but there is no way to prevent drywood termites. You can fumigate your home and within a few days they could be back (but won’t be visible for a year or two at the earliest in most cases). Termites do better here than in many places of the country simply because it’s warmer here.  They may swarm twice a year rather than once. Please also read this post for more info:

    4. Fire / Water: more destructive fire seasons have brought about new, stronger safety regulations including mapped fire zones, higher insurance premiums, and construction limitations. On the other end of the spectrum, the Bay Area has tsunami hazard zones (you can spot the evacuation signs around the bayfront) in addition to the usual flood and dam inundation hazard zones. And expect drought to impact water prices plus restrictions on water useage.

Structural Differences (Houses)

    1. No basements – there are very few homes with basements here (the very old ones and those which are newer and extremely expensive).  A very common question is “where do people store all their stuff if they don’t have a basement?”  For most households, the storage center tends to be the garage. Built in cabinets and storage shelves are highly appreciated. When people purchase homes with 3 car garages, often that 3rd space is not for a car, but for “stuff” – luggage, holiday decor, momentos, old files, etc.
    2. Foundations – older homes are usually built on a “raised” foundation or perimeter foundation with support beams under the center part of the home. Some types of homes, such as Eichler designed houses (mid-century modern ranch style) were built with slab foundations and actually have radiant heating (heating coils built into the slab). Newer homes now tend to be built on slab also (10-15 years of age or less). Most of our valley has 40-60 year old ranch style homes, though, and these are mostly “raised” foundations with a crawl space.
    3. Houses are built to move in case of an earthquake – most of our homes are built with wood and are intended to move in the case of an earthquake.  It is very rare to find a house made out of brick here because they don’t do well in case of severe shaking.
    4. Suburban sprawl – Silicon Valley was built for cars. While BART and VTA are expanding access to some public transit routes, it’s still a very car-dependant area. The median lot size for homes sold in San Jose over the last 2 weeks (as of this writing) was 6,310 SqFt, and the median home size was 1,568 SqFt. Depending on where in the world you are coming from that can sound quite small, but it’s a relatively typical suburban home in this area.

These are perhaps the most salient differences home buyers relocating to Silicon Valley might want to be aware of. Each of these topics could be a blog post of its own, and I have written about all of them! Our blogs offer information on the local market and home buyer, owner, and seller concerns, and we also provide insight into some of the resources and Tools You Can Use When Relocating to the San Jose Area, but an experienced professional Realtor will be your most useful resource for navigating real estate in Silicon Valley.
