Is there Feng Shui for storage units?

There is Feng Shui for homes, offices, even cars so how about storage units?

Still, we don't actually live in storage units, as they are not inhabited structures maybe Feng Shui issues don't exist.

The front door of mine faces an inauspicious direction-do I just rent another storage unit somewhere else or is there a fix for that-say hanging a "Pa Kua" Feng Shui tool on the door?
