When measuring to fs/ns of a elevator shaft or stair shaft do you measure to the side of the shear wall or to the side of the furred out wall on the shear wall?
The standard states:
"Walls that are required by code to enclose a Major Vertical Penetration are included in its area. Additional enclosing walls outside code required enclosing walls, as well as the space between them, are not included in the area of a major vertical penetration, but may be included in the area of adjacent common areas or units."
With that I would say that any furring should be excluded from your measurement of Major Vertical Penetrations.
