California Code, Food and Agricultural Code (Formerly Agricultural Code) - FAC § 47020

(2) As part of obtaining or renewing a certified producer's certificate, a producer farming fruit, vegetables, nuts, herbs, and similar crops shall annually submit to the county agricultural commissioner's office in the county in which the producer's land or facility is located information requested by the department about the specific crops that the producer will harvest or intends to harvest for sale directly to the public. The secretary may promulgate regulations specifying the information a producer is required to submit.

(3) A certified producer's certificate issued by a county agricultural commissioner shall be valid for up to 12 months from the date of issue and may be renewed annually thereafter. The county agricultural commissioner in each county shall perform at least one onsite inspection for all new certified producer's certificate applicants, and may perform additional inspections as needed of the property or properties listed on the certified producer's certificate issued in the agricultural commissioner's county as deemed appropriate by the county agricultural commissioner to verify production of the commodities being sold at a certified farmers' market or the existence in storage of the producer's actual harvested production, or both, of any product being sold at a certified farmers' market. Where practical or purposeful, verification inspections shall be made when the actual harvest or sale of the commodity in question is occurring. The county agricultural commissioner shall provide to the producer a schedule of fees that reflects an estimate of expenses for certification or inspection at the time of application or renewal or before any needed additional verification inspection, and may charge a certification and inspection fee equal to the actual expenses incurred.
