A regular storage unit is an enclosed, climate-controlled box—typically 10x10 to 10x30 feet—designed for household goods or small business items. A contractor storage yard is a much larger open-air space (1,000 to 7,500 sq ft at Lynx) designed for oversized equipment, commercial vehicles, trailers, and building materials that simply can't fit inside a traditional unit. Contractor yards also offer drive-in access, making it easy to load and unload heavy equipment at any hour.
