Direct answer
Exit access doorway is a defined term in the International Building Code (IBC) 2009, in Means of Egress. The code's own words are: “A door or access point along the path of egress travel from an occupied room, area or space where the path of egress enters an intervening room, corridor, unenclosed exit access stair or unenclosed exit access ramp.” The IFC 2009 carries the same definition word for word, so the term means the same thing in each. The term is used in 8 chapters of this corpus, most often in Means of Egress (IBC 2009), Means of Egress (IFC 2009), Special Detailed Requirements Based on Use and Occupancy (IBC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.
