The Legislature finds and declares that increasing numbers of Californians live in manufactured homes and mobilehomes and that most of those living in such manufactured homes and mobilehomes reside in mobilehome parks. Because of the high cost of moving manufactured homes and mobilehomes, most owners of manufactured homes and mobilehomes reside within mobilehome parks for substantial periods of time. Because of the relatively permanent nature of residence in such parks and the substantial investment which a manufactured home or mobilehome represents, residents of mobilehome parks are entitled to live in conditions which assure their health, safety, general welfare, and a decent living environment, and which protect the investment of their manufactured homes and mobilehomes.
