ing, unit size, and coursing heights affect the exact anchor placement.
If the studs are spaced 24 in. on center, the maximum anchor spacing
would be 24 in. on center horizontally 16 in. on center vertically
(every sixth course of brick or every second course of concrete block).
If the stud spacing is 16 in. on center, the maximum anchor spacing
would be 16 in. on center horizontally 24 in. on center vertically
(every ninth course of brick or every third course of concrete block).
Stone veneer is attached in the same way as brick veneer, but the
anchor spacing must compensate for the irregularities of mortar bed
height and still meet code requirements. An anchor spacing of 16 in. on
center, for example, may not accommodate the coursing height of rough
stone. If vertical spacing must be increased so that anchors align prop-
erly with the bed joints, horizontal spacing may have to be decreased to
stay within the maximum allowable wall area supported by each
anchor.
In Seismic Zones 3 and 4, and in areas subject to wind loads of 30
psf (108 mph) or more, each veneer anchor may support a maximum of
2 sq. ft. of wall area. This requires a stud spacing of 16 in. on center
and an anchor spacing of 16 in. on center horizontally 16 in. on cen-
