My former employer (in the midst of a job change) has a parking garage. When I got my Volt, I scoured that garage looking for 110V outlets. Found a bunch along one of the back walls, all lined up nicely with parking spaces (though a little hidden from view behind concrete bollards).
The company is moving soon; had I stayed, I would have started talking with people there about 220V charging stations.
We'll see how things shake out with the new employer, once I'm reasonably settled and have scoped out the landscape (literal and figurative).
