R403.1.6
Foundation Anchorage
Sill plates and exterior sole plates on slabs are anchored with 1/2 in bolts at 6 ft or less, embedded 7 in, in the middle third of the plate, with a nut and washer.
Each plate piece gets at least two bolts, with one within 12 in of each end but no closer than seven bolt diameters.
Short offset walls between braced panels need one bolt if 24 in or shorter, and none if 12 in or shorter, when tied to the panels at the corners.
Foundation Anchorage in Seismic Design Categories C, D
In SDC D (and townhouses in C), braced wall lines get plate washers, interior braced and bearing plates get bolts at 6 ft and within 12 in of ends, and buildings over two stories space bolts at 4 ft.
