Basements aren’t illegal in California . They’re just not as necessary where the weather is warmer and there’s not a lot of rain, ice or snow. Builders found it was cheaper to build a house on a foundation. Most California houses have no attics either.
Under current L.A. zoning, a basement’s area is completely excluded from a property’s maximum square footage restrictions. A basement can be a reasonable way of adding square feet if conditions are right. You can build a basement under an existing house, or–counterintuitively– completely outside of it.
States that have a lot of swamp land or wetland territory, as well as those with significant amounts of coastline, simply have too much water in the ground to make most basements feasible. In cooler climates, the frost line is several feet below the surface, which is why many Northern homes have basements .
But it’s true that basements are rare in California . We have a basement in our California home built in 2007. It is under about one half of the home, and provides major storage space, a mechanical room as well as an additional finished room. But it’s true that basements are rare in California .
Phil Crone, executive director for the Dallas Builders Association, said basements are also not as common in Texas because the frost line — the depth below the ground where the soil does not freeze in the winter — is much shallower in Texas than up north.
Such amenities can drive up the cost, from $200 to $300 per square foot to $1,000 and up. While the cost of building a basement depends entirely on the particular conditions of a site, it typically adds at least $150,000 to the price of new construction.
Given that your home will probably still be standing (though it certainly may be damaged) after the quake , the basement shouldn’t be any more dangerous than any other part of the house. Just duck under a table or desk like you would on the main floor.
Technically, there isn’t any major obstacle to extending the underground space from a basement under the yard , depending on local geological conditions. A “cut and cover” project would be relatively straightforward to build .
An above-ground storm shelter costs $3,000 to $15,000, compared to $4,000 to $30,000 for an underground unit. An above-ground unit or safe room typically goes in a garage or basement. You can also install it on a concrete foundation that is separate from the home.
According to the United States ‘ Census Bureau’s Survey of Construction, basements are on a downward trend. In 2000, 40% of homes were built with basements . The seven states of this region are: Iowa. Kansas. Minnesota. Missouri. Nebraska. North Dakota. South Dakota.
A monolithic concrete slab will typically cost $4,500 to $12,000, which is cheaper than either a crawl space or a basement . Slab foundations on average are about $10,000 cheaper than most crawl spaces. How much would it cost to build a 1000 square foot house ?

Because the basement acts as a foundation. They also act as protection against certain weather, from freezing temps to tornadoes. There are plenty of places that don’t have them though, especially in warmer climates.
It’s actually MUCH more expensive to build up that to build down. Much of the work of constructing a basement is going to get done with a new house, whether you dig a basement or settle for a crawl space. (These days, it can often be used to build the mound type of leach bed many localities require.)
If you’re building a home, a concrete slab makes sense because of its low cost . It’s the cheapest option available, and, comparatively speaking, it’s the quickest solution. The right crew can lay a concrete slab foundation in a short period of time, and the drying process doesn’t take much longer.
