dnk IMO as far as the NEC is concerned that is a structure. The definition is what it is, no mention of keeping the elements out. [Linked Image]

When the NEC states building I think of something that keeps the weather out.

When the NEC states structure I think of anything except a building.

To the NEC a sign or light post is a structure. If you doubt that take a look at 225.32 Exceptions 3 and 4.

ARTICLE 225

II. More Than One Building or Other Structure

225.31 Disconnecting Means.
Means shall be provided for disconnecting all ungrounded conductors that supply or pass through the building or structure.

225.32 Location.
The disconnecting means shall be installed either inside or outside of the building or structure served or where the conductors pass through the building or structure. The disconnecting means shall be at a readily accessible location nearest the point of entrance of the conductors. For the purposes of this section, the requirements in 230.6 shall be permitted to be utilized.

Exception No. 3: For towers or poles used as lighting standards, the disconnecting means shall be permitted to be located elsewhere on the premises.

Exception No. 4: For poles or similar structures used only for support of signs installed in accordance with Article 600, the disconnecting means shall be permitted to be located elsewhere on the premises.

Poles for signs and lights are structures and without those exceptions would require a readily accessible disconnecting means at the poles themselves.
