Thank you!

Ok so I see he post is old but hope to get a response. So I have the same stuff on the side of my house. My house was just built in September and the North side has 3 "runs" down the side that look just like it (thanks for the pics). I am not sure what building code is (have to look) but it appears the bathroom exhaust fan isn't piped outside just into the attic so I agree it is some sort of condesation going to the outside. My question now is what is the proper fix?
