9.24.3.3.(1)

Intent 1:

To limit the probability of inadequate strength or stiffness, or an insufficient surface for the attachment of cladding, sheathing or interior finish materials, which could lead to an inability to resist expected lateral and gravity loads.

This is to limit the probability of the excessive movement or deformation of walls, which could lead to:

• the structural failure of walls, or
• for exterior walls, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration.

This is to limit the probability of:

• the space being unsuitable for its intended use,
• compromised operation of windows and doors, or
• damage to the building.
