Welfare and Institutions Code section 19631

The department shall not cause or permit the establishment or placement of any blind vendor in a vending facility unless the director, in consultation with the committee of licensed blind vendors, first determines that the facility produces, or is likely to produce within a reasonable time, an adequate net income for a blind vendor.

Nothing in this article prohibits the entity or person controlling property on which a vending facility is located from making, to the blind vendor operating it, payments in supplementation of proceeds realized from sales.
