TL;DR
A shear wall is a wall engineered to resist lateral forces from wind or earthquakes, transferring them through structural sheathing, closely spaced nailing, and hold-down anchors into the foundation. In wood-frame homes it is typically plywood or OSB panels with a specified nail size and spacing, details that look identical to ordinary walls once covered.
What it means
A shear wall is a wall engineered to resist lateral forces from wind or earthquakes, transferring them through structural sheathing, closely spaced nailing, and hold-down anchors into the foundation. In wood-frame homes it is typically plywood or OSB panels with a specified nail size and spacing, details that look identical to ordinary walls once covered. Cutting an opening into one during a remodel requires an engineer's fix, which is why permit reviewers ask for the original structural plans.
