Here too, its legal. However, just because its legal does not mean its wise to do. Exhaust fans pull moisture and hot air out of the bathroom. If you let that circulate around in an attic it could possibly create a condition for mold growth.

In your picture thats the wrong vent anyways ... if its to be vented through the soffit. That's soffit ventilation.
1st choice: out of a vent designed for exhaust ventilation
2nd choice: out of a roof vent (which is how 90% of fans are vented)
3rd choice: out the gable end of a roof

Can't imagine it going out the soffit. That would direct it down putting a turn that would collect moisture. Maybe I misunderstood.

The setup in that picture I posted is the best way to vent. With exception to the run going horizontally. I would go straight up to the roof not horizontally as is pictured. Going out the soffit is allowed in some places, but I do not suggest going that route.

If it were my house I would keep the Exhaust fan ventilation separate from all other vents as ridge vents, drain waste vents, soffit vents, dryer vents, etc. all have a different function and purpose.
