In California seismic zones, what is the required nail spacing for structural sheathing at panel edges when using 15/32-inch OSB sheathing on exterior walls?
Correct Answer
C) 6 inches on center at edges, 12 inches on center in the field
CRC Table R602.3(1) and California seismic provisions require 6-inch spacing at panel edges and 12-inch spacing in the field for 15/32-inch structural sheathing. This spacing provides adequate shear resistance for California's seismic requirements while being practical for construction.
