Client previously built an R-3 home in Los Angeles under 2014 LA Building Code (based on the CBC and IBC), with the intention of changing it into an R-2.1 occupancy in the future, if planning code allowed it. The original plans did not call for type X gyp board (but crawling through the attic I can verify that at least the ceiling gyp board has Type X labels). The rest of the membranes are unverifiable without tearing them all off.
Client now has planning approval but has an uphill battle forensically demonstrating the one-hour construction required for a licensed facility.
In 2014, table 601 footnote (d) allowed a full NFPA 13 system to substitute for 1 hour construction at all interior structural bearing walls and the roof. As far as I can tell, that option no longer exists in the 2022 LABC/CBC/IBC.
Question: if you were the building official, would you allow a modification request to utilize the 2014 code provision in 2023, and sprinkler it in lieu of completely re-drywalling the entire structure?
If "no", then a follow-up question: would you allow it if the request was accompanied by a report form a Fire Protection Engineer?
