Most drinking and dining establishments must be licensed by the Multnomah County Health Department. You may call them at (503) 988-3400. Food establishments that make more than half of their sales from the manufacture or sale of food products for off-site consumption will generally require approval from the Oregon Department of Agriculture Food Safety Division.

BDS won't issue a permit for your food establishment until you turn in a copy of the stamped Multnomah County approved plan, or documentation from the Department of Agriculture showing that they have approved the project.
