Per Montgomery County: The Montgomery County Department of Permitting Services (DPS) has removed permitting barriers to allow produce growers to build high tunnel-type greenhouses on urban and suburban properties, a benefit previously reserved for land designated as agricultural. High tunnels can be a key piece of farm infrastructure for vegetable growers to increase food production. Similar to a greenhouse, a high tunnel is a less permanent structure, built with a metal frame and plastic cover instead of glass and metal. High tunnels extend the growing season by trapping heat and protect crops from diseases and pests.
Urban agriculture is fundamental to achieving food systems resiliency in the County, increasing urban access to nutritious food and empowering urban residents. Previously, a building permit from the County was required for high tunnels on properties not agriculturally assessed for tax purposes. It is often difficult for properties with fewer than three acres to obtain the necessary agricultural assessment. This requirement had presented a barrier to new farmers and those with fewer means on urban and suburban properties.
