I think it's a great AHJ issue as well as the other comments.
If your saying your going to penetrated a fire wall in the attic I'm sure that the minimum requirement is to maintain that fire rating based on the UL type
materials that have by design and by application achieved the desired fire rating needed.
Theres all type of sleeves both buyable and makeable that can maintain that existing fire rating!
Well, I was kind of wrong on this one. IRC 317.2 states that each Townhouse shall be considered a separate building. That means you cannot pass a feeder through that building without a disconnecting means. The IBC requires all other multifamily dwellings to have sprinklers. There is no such thing as a condominum according to the ICC. So I guess I was right after all.
