Cal. Civ. Code § 1954.25
The Legislature finds that the price charged for commercial real property is a matter of statewide concern. Price controls on commercial rents discourage expansion of commercial development and entrepreneurial enterprise. These controls also discourage competition in the open market by giving artificial price benefits to one enterprise to the disadvantage of another. Because the impact of these controls goes beyond the local boundaries within which the controls are imposed, the adverse economic consquences become statewide.
In order to prevent this statewide economic drain from occurring, the Legislature hereby enacts a uniform system with respect to commercial rents, which shall apply to every local jurisdiction in the state. This legislative action is needed to prevent the imposition of artificial barriers on commercial rents, as well as to define those areas not included within the definition of commercial real property.
In making these findings and in enacting this chapter, the Legislature expressly declares its intent that this chapter shall not apply or be interpreted to apply to local rental controls on residential real property.
