Several questions about Section 302.1 of the International Existing Building Code (IEBC) regarding additions are raised and answered:

Q: Would an alteration of an attic into living space be considered an addition under Section 302.1, therefore having to comply with the International Building Code (IBC) in total for the new space?

Q: A basement is being converted from a storage area into a finished recreational room in an office building. Would this be considered an addition of floor area and need to comply with the IBC for height and area as well as the IECC for new construction?

Q: If the prescriptive compliance method for an addition is applied, would the addition of a non-occupiable appendage such as an elevator or exit stair shaft be considered additional area of the building to be included in the overall area calculation in accordance with Chapter 5 of the IBC?
