Industrial garages and outbuildings can be built using a variety of materials and range from smaller properties, often called "Flex" or "R&D" properties, to larger office service or office warehouse properties to the very large "big box" industrial properties.
An important, defining characteristic of industrial space is Clear Height. Clear height is the actual height, to the bottom of the steel girders in the interior of the building. This might be 14–16 feet for smaller properties, and 40+ feet for larger properties.
We also consider the type and number of docks that the property has. These can be Grade Level, where the parking lot and the warehouse floor are on the same level, to semi-dock height at 24 inches, which is the height of a pickup truck or delivery truck, or a full-dock at 48 inches which is semi-truck height. Some buildings may even have a rail spur for train cars to load and unload.
