406 Storage Warehouse

These buildings are designed for storage and include an amount of office space commensurate with the quality of the building (typically 3 to 12 percent).

Typically, they have plaster or drywall interior partitions and may have some finished ceilings. The better qualities have small office fronts with ornamental materials at the front elevation, while lower cost structures are plain with very little if any ornamentation. Heating and ventilating facilities are sufficient to protect goods from freezing and other spoilage.

The following are not included in the costs: Special climate control equipment and dock levelers and material handling equipment.
