Brick Veneer Anchor Spacing and Count (TMS 402 / IBC 1405)
Anchor count = ceil(area / area-per-anchor) with the 32 in horizontal / 24 in vertical spacing caps, per TMS 402 / IBC 1405. A 200 ft^2 veneer at 2.67 ft^2/anchor -> 75 ties; a high-wind 2.0 ft^2 limit -> 100. TMS 402 / IBC and the engineer of record govern.
Formula and source
anchors = ceil(area / area_per_anchor); area_per = 2.67 ft^2 typical (2.0 high-demand); max 32 in horizontal, 24 in vertical spacing.
TMS 402 (Building Code Requirements for Masonry Structures) and IBC 1405 veneer-anchor provisions, by name.
