9.23.17.1.(1)

Intent 1:

To limit the probability of inadequate support or fastening for exterior cladding, which could lead to an inability to resist expected lateral loads, which could lead to the deformation or detachment of cladding.

This is to limit the probability of precipitation ingress, which could lead to deterioration, which could lead to compromised structural integrity of the wall, which could lead to:

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