California Code, Health and Safety Code - HSC § 33751

(a) Facilitate increasing the supply of urban housing and ease the housing shortage that exists in many parts of the state.

(b) Encourage Californians of all social and economic positions to reinhabit urban areas, thereby rendering these areas more socially balanced and economically self-sufficient.

(c) Reduce pressures for suburbanization and thereby mitigate many of the problems caused by urban migration, including inefficient use of scarce energy resources and urban sprawl.

(d) Stimulate urban building and construction activity and thereby increase urban employment and improve the urban tax base.
