I don't know where venting a bathroom fan out the soffit is a code
violation? Here in NJ most homes are done that way and we are about
as regulated as it gets. I don't see anything wrong with doing a
soffit vent.

What happens is that warm moist air is drawn into the next soffit vent
into the attic space where it can cause damage. Remember that soffit vents
are normally air inlets.
