Cal. Food & Agric. Code § 47021

(a) Every operator of a certified farmers’ market shall remit to the department, within 30 days after the end of each quarter, a fee equal to the number of vendors participating and selling goods under the authority and management of the certified farmers’ market operator participating on each market day for the entire previous quarter. The fee shall be two dollars ($2) for each vendor whose products were presented for sale on each market day. A certified farmers’ market operator may directly recover all or part of the fee from the participating vendors. An operator of a certified farmers’ market located in a county with a population of less than 400,000 that allows only vendors of agricultural products produced by producers on land located in the same county as the certified farmers’ market may petition the secretary for a vendor fee of one dollar ($1). The petition shall include a statement of verification of the information upon which the petition is based by the county agricultural commissioner in the county where the certified farmers’ market is located.
(b) An operator of a certified farmers’ market who fails to pay the required fee within 30 days after the end of the quarter in which it is due shall pay to the department a monthly interest charge on the unpaid balance and a late penalty charge, to be determined by the department and not to exceed the maximum amount permitted by law.
