(Gresham, OR) -- In-N-Out Burger is taking a major step toward expanding in the Portland area with the purchase of a 71-thousand-square-foot industrial building in Gresham. The California-based chain bought the property on Northeast Sandy Boulevard as part of a plan to serve the regional market. The space will support distribution and operations as In-N-Out prepares for future restaurant openings across the metro. Since 2019, the chain has opened locations in Keizer and Ridgefield, Washington, and has filed plans for sites in Beaverton, Vancouver, Hillsboro, and near Portland International Airport.
