I just looked at a few buildings here in town. While these were commercial/industrial rentals .... the typical tenant has a two room office in front, with a warehouse / shop / garage taking up the bulk of the space, I really liked the way the service was set up.

(Total building volume was about 22,000 sq ft, with each space maybe 1700 sq ft on average).
There was an electric room, which held a meter and disconnect for each unit.
Within each unit, there was a 480 panel, a transformer, and a 208/120 panel. Everything was surface mounted, so access was easy.
