Since 1969, California has required that all cities and counties plan to meet the housing needs of everyone in the community. California’s local governments meet this requirement by adopting housing elements as part of their “general plan” (also required by the State). General plans serve as the local government’s "blueprint" for how the city and/or county will grow and develop and include eight required elements: land use, transportation, conservation, noise, open space, safety, environmental justice, and housing (a ninth element, air quality, is required for cities and counties in the San Joaquin Valley). The law mandating that housing be included as an element of each jurisdiction’s general plan is known as “housing element law.”
California’s housing element law acknowledges that, for the private market to adequately address the housing needs and demand of Californians, local governments must adopt plans and regulatory systems that provide opportunities for (and do not unduly constrain) housing development. As a result, housing policy in California rests largely upon the effective implementation of local general plans and, in particular, local housing elements.
