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.
The chief culprit of most missing basements in the South is damp soil. Even in drier climates, the clay composition in the soil can make basements impractical or even dangerous. While this kind of soil doesn’t have enough water in it to cause flooding, mold, or rot, it can play havoc with the basement walls.
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.
There are several reasons why brick isn’t predominant: The climate: California’s weather is pretty temperate-we don’t get subzero temperatures like back East or in the Midwest, so we don’t need the extra insulation. On top of that, in parts of California , it can get very hot, and brick holds heat in.
Florida has a large aquifer system that spans around 100,000 square miles and provides water for many large cities. The groundwater’s very close to the surface in most parts of Florida and Southern Georgia. Because of the high water table and proximity to the ocean, it is impossible to dig out for a basement .
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.
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.
The Western part of the country (including the Midwest) is the area where basements are most popular. One region in particular – the West North Central States – is the heartland of basements . This region consists of the states west of the Mississippi and east of the Rockies.
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 ?

The cost of a basement is between 10 and 35 dollars per square feet. Let’s say an average basement is 1,000 square feet of finished space. So the cost of a basement is between $10,000 and $35,000. 10k if you’re doing most of the work yourself and up to $35,000 if you’re hiring a contractor to finish your basement.
In the United States, on average, finishing a basement will give you a return of 70 to 75% of your investment. For example, if you spent $1,000 on improvements, it would increase the value of the property by about $700. If you spent $10,000 on improvements, it would increase the value of the property by about $7,000.
The cost to dig a basement for new construction is $12,000 to $36,000 . Basement excavation costs $10 to $20 per square foot and takes 2 to 4 weeks to dig-out and build. Digging a basement under an existing house averages $47 per square foot because the house must be raised first.
