Thank you for the responses I received. Based on this information I have asked the Architect to review once more his review. BTW the 2020 NYSBC codes are the documents being used.

But a solid concrete slab makes that a fairly easy exercise and the only upgrades would be the ratings of fire stops because shafts for utilities and stairs will be what they will be based on the construction type and FR rating.

Building codes are typically very clear on what characterizes a building to be separate and distinct. Either build a building by itself, build multiple buildings and separate by fire separation distance is specified by the code, build two buildings right smack up against each other and separate by an approved or listed firewall assembly, or use the special provision in the IBC that applies typically to what we call podium-style buildings. Section 510.2 of the 2018 IBC requires a horizontal assembly having a fire resistance rating of not less than three hours for a single building to be considered as separate and distinct buildings. A 2-hour fire separation assembly effectively serves to separate fire areas, but, in my opinion, it would not qualify a single structure to be considered as separate and distinct buildings recognized by the building code. Rather, it would be categorized as a mixed occupancy, requiring NFPA 13 sprinkler protection throughout. Am I missing something?
