This situation is described in publication 463, chapter 4.

It depends on whether your home is your regular place of business, so that you could qualify for the home office deduction. (You don't actually have to claim the home office deduction, but your home must be your regular place of business so that you could qualify.)
If your home is your regular place of business within the meaning of the chapter, then any trips to other work locations are deductible mileage. However, if you work many places and have no regular place of business, then the only mileage that is deductible work mileage is if you work at more than one secondary location in the same day.
