Haha for residential
The box has DC Supercharger written on it in black.
I can see why you think it is a poor location choice for them, but as far as I know there are many superchargers in SF that are in urban area where locals charge everyday and create a lineup to a point where they need a valet service. Plus, Montreal had a supercharger location with only 2 chargers until recently. Link is here..

I also believe Tesla considers those 'apartment dwellers' without proper charge plug. I dont really drive around much during the week, and someone else may correct me if they have seen a location where they saw the chargers being installed (that may not even happen yet since the chargers only need to be installed in 2016 not necessarily in May) but I cant see why they would store boxes there when they are not going to install them there.
I dont mind being proved wrong but this location seems to be it... for now at least. I assume at least a couple thousands of ppl from Lower Mainland reserved Model S, so they may move the chargers or install additional ones at another location in the future.
