The recommended spacing for weep holes in brick veneer is typically every 32 inches to 36 inches on center, depending on the specific building codes and practices adopted in a region. Choosing a spacing of 36 inches aligns well with best practices in construction, as this distance provides adequate drainage opportunities for moisture that can accumulate behind the veneer.

Weep holes are crucial in brick veneer installations because they allow water that penetrates the outer layer to escape, preventing moisture buildup which can cause deterioration, mold growth, or damage to the structural components of the building. This is particularly important in areas with high rainfall or humidity.

The other options, which suggest larger spacings of 48 inches or 60 inches, may compromise the effectiveness of moisture drainage. Such spacing could lead to areas where water might pool or become trapped behind the brick, increasing the risk of damage over time. Therefore, the choice of 36 inches ensures that moisture is effectively managed, keeping the structure safe and sound.
