Cal. Lab. Code § 2654
If, on the basis of information in its possession, with or without an investigation, the division shall find that industrial homework cannot be continued within an industry without injuring the health and welfare of the industrial homeworkers within that industry, or without rendering unduly difficult the maintenance of existing labor standards or the enforcement of labor standards established by law or regulation for factory workers in that industry, the division shall by order declare such industrial homework to be unlawful and require all employers in the industry to discontinue manufacture by industrial homework. The order shall set forth the type or types of manufacturing which are prohibited after its effective date, and shall contain such terms and conditions as the division may deem necessary to carry out the purpose and intent of this part.
