I know this topic is old but I am going thru a home inspection for the sale of my home and this issue has come and I keep hearing several different scenarios so help me out. I bought my house in 97 and when I did my warranty order to the builder I noted that the bathroom fan vents have a open space in the attic before going outside. The builder called the plumber who installed them and he came out and said they were fine and within the limits (I think there was an open section in the pipe going out the attic-maybe 4 or 5 inches) anyways now we are selling our house and the home inspector for the buyer says this is wrong and they need to be totally vented to the outside. My husband does not want to change it-his theory is that the attic is well ventilated and we live in arizona so any moisture that does go to the attic dissipated pretty quickly anyways. Is there a website that I could go to and find out exactly what code is on this so I can deal with this issue with confidence? Thanks to anyone that can help.
