Which Code? Where is the Project? Oman? Oxford? Oregon?
International Building Code?

In accordance with Section 3.4.4.1 it depends on the fire-resistance of the construction for the Group classification and Division (Ref. 1.1.2.2).

thanks, The only information I have is that the building is part 9 and that means three or fewer storey in building height, not more than 600 sqm, major occupancies could be(C,D,E,F2,3 )

See the table for occupancy types for FR required.
