What does current Washoe County Code say about cargo containers?

In current Washoe County Code chapter 100 (Building Code), “Any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building or structure…”  is required to obtain a building permit, unless that structure is less than 200 square feet in size.  While these types of storage structures do not require a permanent foundation, and are considered personal property, they are not “temporary” structures in terms of the Building Code which defines temporary structures as being in place for no more than 180 days.
