Two Story Structure
Two Story Structure
(OP)
By code what is the deciding fact on whether or not a structure is two stories, nacessitating the use of an 8" wide stem wall with a larger footing?
I have a standard house with an 8 foot plate height and a 6:12 roof pitch where the owner wants to make the upstairs liveable. I think this occupancy use issue drives the 8" wall.

The 2012 IRC definition of a story is:
STORY. That portion of a building included between the upper surface of a floor and the upper surface of the floor or roof next above (also see "Basement," "Building height," "Grade plane" and "Mezzanine"). It is measured as the vertical distance from top to top of two successive tiers of beams or finished floor surfaces and, for the topmost story, from the top of the floor finish to the top of the ceiling joists or, where there is not a ceiling, to the top of the roof rafters.
The attic would be considered a story. I'd double check to verify that Washington state's definition is the same.
