Farmers Market

If you would like to have a booth at any certified Farmers' Markets you should first contact the market manager to check space availability and any additional requirements. Second, you need to obtain a Certified Producer Certificate (CPC) from any of our offices. It must include a map of the growing grounds, a notarized lease (if applicable), and a list of the commodities grown including variety/type, amount, harvest season and estimated production. The cost of this certificate is $63.00. 

You may submit your application online, using the a link below.  Once our office approves it, we will contact you for a signature and payment.
