Wall sheathing overlapping sill plate??

[codehelpneeded]

I cannot find a code in the IRC that requires sheathing to overlap the sill plate. I know it is good practice, but is there a code? The anchor bolts hold the sill to the foundation, and overlapped sheathing holds the wall to the sill. I've also looked through the AWC NDS as well.

It will be in 602 if you're doing a prescriptive design. Most likely 602.10, or 602.12 if you're in SDC A or B (and sometimes C).

R602.10 Wall bracing. Buildings shall be braced in accordance
with this section or, when applicable, Section R602.12.
Where a building, or portion thereof, does not comply with
one or more of the bracing requirements in this section, those
portions shall be designed and constructed in accordance with
Section R301.1.
R602.10.2 Braced wall panels. Braced wall panels shall
be full-height sections of wall that shall not have vertical
or horizontal offsets. Braced wall panels shall be
constructed and placed along a braced wall line in accordance
with this section and the bracing methods specified
in Section R602.10.4.

Not required....You do need an uplift load path, it is just not specific....

R602.3.5​

Braced wall panels located at exterior walls that support roof rafters or trusses (including stories below top story) shall have the framing members connected in accordance with one of the following:

1. 1.Fastening in accordance with Table R602.3(1) where:
   
   1. 1.1.The ultimate design wind speed does not exceed 115 mph (51 m/s), the wind exposure category is B, the roof pitch is 5:12 or greater, and the roof span is 32 feet (9754 mm) or less.
   2. 1.2.The net uplift value at the top of a wall does not exceed 100 plf (146 N/mm). The net uplift value shall be determined in accordance with Section R802.11 and shall be permitted to be reduced by 60 plf (86 N/mm) for each full wall above.
2. 2.Where the net uplift value at the top of a wall exceeds 100 plf (146 N/mm), installing approved uplift framing connectors to provide a continuous load path from the top of the wall to the foundation or to a point where the uplift force is 100 plf (146 N/mm) or less. The net uplift value shall be as determined in Item 1.2.
3. 3.Wall sheathing and fasteners designed to resist combined uplift and shear forces in accordance with accepted engineering practice.
