[QUOTE]Originally posted by codenut:
[b]Well, interesting question. I have posed this to the chief here and our official stance which the builders seem to be ok with is: 2" sheetrock shaft wall attached to the framed walls on either side, extending the entire length of the common wall, from slab to underside of roof deck, with all gaps and openings sealed. Underside of roof deck either covered with sheetrock for a distance off 4 feet from the shaft wall with NO penetrations what-so-ever. OR fire rated plywood installed for a minimum distance of 4 feet again witout penetrations.
Does this answer your Q ?[/b][/QUOTE]

What are you basing the "no penetrations" what-so-ever in the four foot area of the FTR or sheetrock roof deck. This is not a rated assembly. Nothing in the code that I can see that would prohibit a vent or even a skylight.

Yes. One roof is ok if it is designed and installed to be structurally independent unit to unit i.e. if one unit collapses the roof over the adjacent unit does not. Two one hour walls would be permitted if they meet the criteria set forth in R302.1. Continuity of these walls should comply with R317.2.1.
