  • R602.10

    Wall Bracing

    Used in checks
    • Houses are braced per R602.10 or the simplified method; any part that doesn't fit is engineered.

    International Residential Code, 2024 · Chapter 6, Wall ConstructionRead the full text (opens UpCodes in a new tab)

  • R602.10.3

    Required Length of Bracing

    • Required bracing length per line comes from the wind table (and the seismic table in SDC D or for SDC C townhouses), times the adjustment factors; only parallel panels count.
    • Wind bracing grows with exposure (C x1.2-1.4, D x1.5-1.7), taller roofs and walls and more wall lines; dropping interior gypsum adds 40%, and skipping horizontal blocking doubles it.
