How far from the septic field for an outbuilding?

I do not believe there is any. It just needs to be far enough away so that you do not hit it when excavating for the foundation which has to be 4' down so it is below the freeze line. If it were me the first thing I would do is go and talk to the building inspector as he is the one with the last word plus you have to be so many feet from all property lines.
