The Code regulates all construction, unless it’s non-structural, (i.e.: carpet, paint, etc.) All work (projects) are reviews for 1) building compliance (height, size, guardrails, stairs, etc.), 2) fire code (setbacks, etc.), 3) structural, 4) energy use, if applicable
Under “structural”, Table 2304.9.1 Fasteners applies. As you’ll see in Item #29, you’ll see joists fastened to band joist or rim joists can be by:
3 - 16d common face nailed, or
4 - 10d box face nailed, or
4 - 3” x 0.131” face nailed, or
4 - 3” 14 gage staples with 7/16” crown face nailed
Nowhere do they allow toe-nailing for this type of installation.
