We a currently using the 2009 edition of NFPA 101 and 1 so my questions pertain to those editions of the codes. Fore an existing three-story 3 unit apartment building using option 1 (no protection or Fire alarm systems) what is the fire door requirement for the exit stairway in the building. I see the required resistance rating of fire doors in table but I cannot find a code path from chapter 31 that section of chapter 8. Is a 1 hour fire door required in a existing 3 story 3 unit apartment building?
