The Legislature finds and declares that manufactured housing, by virtue of its production costs and sales prices can provide a source of decent, safe, and affordable shelter for persons and families of low and moderate income. The Legislature finds and declares that the availability of manufactured housing has been limited by inadequate sites for such manufactured housing and by the costs of financing the purchase of such housing. The Legislature finds and declares that, if California is to effectively meet the housing needs of persons and families of low and moderate income, it must encourage increased manufactured housing production, new manufactured housing developments, and the purchase of new manufactured housing by persons and families of low and moderate income. Therefore, it is the intent of the Legislature that the Department of Housing and Community Development and the California Housing Finance Agency, in implementing the programs established by this division, as amended by the Manufactured Housing Assistance Act of 1980, shall encourage increased availability and affordability of manufactured housing for persons and families of low and moderate income.
