We do it every day in IBC buildings.
Ok, i'll keep playing...You are allowed to use the IBC for a SFD.....Which will still have the manufacturers installation instructions requirement...
[A] 107.2.4 Exterior wall envelope. Construction documents
for all buildings shall describe the exterior wall
envelope in sufficient detail to determine compliance with
this code. The construction documents shall provide
details of the exterior wall envelope as required, including
flashing, intersections with dissimilar materials, corners,
end details, control joints, intersections at roof, eaves or
parapets, means of drainage, water-resistive membrane
and details around openings.
The construction documents shall include manufacturer’s
installation instructions that provide supporting
documentation that the proposed penetration and opening
details described in the construction documents maintain
the weather resistance of the exterior wall envelope. The
supporting documentation shall fully describe the exterior
wall system that was tested, where applicable, as well as
the test procedure used.
And then you would have to meet Ex #2 to use a flush caulked
assembly that does not drain to the exterior...
1403.2 Weather protection. Exterior walls shall provide the
building with a weather-resistant exterior wall envelope. The
exterior wall envelope shall include flashing, as described in
Section 1405.4. The exterior wall envelope shall be designed
and constructed in such a manner as to prevent the accumulation
of water within the wall assembly by providing a water resistive
barrier behind the exterior veneer, as described in
Section 1404.2,
and a means for draining water that enters the
assembly to the exterior. Protection against condensation in
the exterior wall assembly shall be provided in accordance
with Section 1405.3.
Exceptions:
1. A weather-resistant exterior wall envelope shall not
be required over concrete or masonry walls designed
in accordance with Chapters 19 and 21, respectively.
2. Compliance with the requirements for a means of
drainage, and the requirements of Sections 1404.2
and 1405.4,
shall not be required for an exterior wall
envelope that has been demonstrated through testing
to resist wind-driven rain, including joints, penetrations
and intersections with dissimilar materials, in
accordance with ASTM E331 under the following
conditions:
And I am liable if I accept an engineers mistake that I know about.
It's called malfeasance........Not only that, but it puts my municipality
on the hook in theory forever where your liability ends with you...
