A crawlspace is a type of home foundation quite common in some parts of the US, specially in the South. Houses are usually built with 3 different types of foundation: concrete slabs, basements and crawl spaces. Concrete slabs are usually placed on top of concrete footings, above grade. Basements are foundations built, or poured into dug pits, usually as deep as 8ft below grade level. Crawlspaces could be considered half way between the concrete slab and the basement. They can be build almost completely above grade, raising the house above terrain level, or half way below grade. The clearance between the floor and the ceiling of a crawl space is usually around 4 ft, so that you can only enter the area by crawling in - thus the name crawlspace. Some people also call crawlspace some service areas built between floors of a multi-level building or between the ceiling of a house and the roof known also as an attic, but the name is most often used to describe the foundation.
