The amount of space required is minimal. For a 20′ storage container, you will need approximately 65 feet of straight clearance. For a 40′ storage container, you will need approximately 120 feet of straight clearance. The width requirement is approximately 10 feet, plus enough room for the truck to swing back into place. These aren't hard and fast rules though. Sometimes the driver can make the delivery with less space if there is room to the side. Be sure to speak to your sales representative about your space.
