I know 13R states they arent required, but what if the bottom floor
where access is provided to the elevator is installed as per 13 and the
rest of the building is installed as per 13R?

I understand all of that, however the fact is that ASME A17.1 requires
"non-combustible" shaft and passenger car, unless I am mistaken. So if the
shaft and car are IAW ASME then it should be considered non-combustible,
correct?
Thanks,

Just because there is sheetrock on the wood framing doesn't mean the shaft is
considered non-combustible and automatically meets the required resistance
rating as required by the code.

"or limited combustible" was added to NFPA 13 in the 2010 edition so
that paper covered gypsum would be allowed in elevator shafts and
still omit the sprinkler. NFPA 13R is a little different in that
gypsum could be attached to wood studs, making it a combustible
shaft. However

Sorry if this gets posted twice. I sent the first one 1/2
st of the building (type 5b) that it is considered a combustible
shaft. The shaft is also 2-hour rated. The shaft and car are manufactured and
installed IAW ASME A17.1. When 13R (2010 ed) references combustible elevator
shafts, aren't they referring to the exposed surfaces? As well,
