| Attribution | |
| Application | Application 1: Location of flashing beneath weep holes in masonry
veneer over wood-frame walls sheathed with a sheathing membrane, a non-wood-based
rigid exterior insulating sheathing or a semi-rigid insulating sheathing with
an integral sheathing membrane, in buildings to
which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application
of Part 9]:
Exceptions:
except as stated in Sentence 9.20.1.1.(2), which applies to buildings other than described above, or where the masonry

limit states.

| Intent | Intent 1: To limit the probability of water running down the face
of the sheathing membrane or insulating sheathing, which could lead to water
entering the backing assembly. Where masonry veneer is
installed to provide the required noncombustible cladding, this is to limit
the probability of deterioration, which could lead to compromised fire resistance
of the assembly, which could lead to harm to persons.
