In Southern California, many homes are built with a slab-on-grade foundation. But some homes have a crawl space. Why would a home have a crawl space? What is the purpose of a crawl space?<\/p>\n\n\n\n

\"What<\/figure><\/div>\n\n\n\n

There are a couple of reasons a builder might choose to add a crawl space to a home. <\/p>\n\n\n\n

  2. Leveling the ground prior to building: When building a slab-on-grade foundation the ground has to be level. We have a lot of sloping properties in SoCal and it can get very expensive to level the ground enough to pour a foundation. In many cases, a crawl space is more cost-effective in this scenario.<\/li>
  3. A slab may not be possible: Some properties just don’t work on a slab. Waterfront or sloping properties might not allow for a slab and a crawl space is the only way to go. <\/li><\/ol>\n\n\n\n

    There are some downsides to crawl spaces, however. <\/p>\n\n\n\n

    Because crawl spaces vent to the outside, moisture and humidity can be a huge problem in a crawl space. This can lead to the following problems that you really don’t want to have:<\/p>\n\n\n\n
