Cal. Welfare and Institutions Code § 4317

At each state hospital at which there is established a sheltered workshop, there shall be a sheltered workshop fund administered by the clinical director. The fund shall be used for the purchase of materials, for the purchase or rental of equipment needed in the manufacturing, fabricating, or assembly of products, for the payment of remuneration to patients engaged in work at the workshop, and for the payment of such other costs of the operation of the workshop as may be directed by the medical director. The clinical director may cause the raw materials, goods in process, finished products, and equipment necessary for the production thereof to be insured against any and all risks of loss, subject to the approval of the Department of General Services. The costs of such insurance shall be paid from the sheltered workshop fund. All money received from the manufacture, fabrication, assembly, or distribution of products at any state hospital sheltered workshop shall be deposited and credited to the hospital’s sheltered workshop fund.
