California law provides a broad definition of the phrase, “dwelling house.” The final determination of whether a structure is a dwelling depends on whether the facts of a case show that the “home” was being used as a residence. “Used as a residence” means that the inhabitant of the dwelling has to be using it for sleeping and storage of his/her possessions. There is no requirement under the law that a dwelling has to be set on any type of foundation. A structure can amount to a dwelling house even if it is on wheels and not restricted to a specific location.
