Agriculture/Weights & Measures

The Agricultural Commissioner enforces the laws and regulations of the California Food and Agriculture Code and the California Code of Regulations while serving at the discretion of the County Board of Supervisors and CDFA Secretary of Agriculture. Sonoma County Agricultural Commissioner’s office employs a staff of twenty-three and has its main office in Santa Rosa with satellite offices in Sonoma and Petaluma.

 The Agricultural Divison acts under the jurisdiction and direction of the California Department of Food and Agriculture (CDFA), and the California Department of Pesticide Regulation (DPR), and works in cooperation with various federal, state, regional and local agencies.

Weights and Measures is mandated by state law to protect the interests of the buyer and seller to ensure honesty and integrity of everyday business transactions. This protection is accomplished through our continuous and systematic inspection of all equipment that weighs or measures a commodity that is sold. Every transaction involving the exchange of goods, property, and service is affected in a very vital way by some form of weights and measures.
