In open weep hole systems, what is the maximum spacing?

Explanation:
Open weep hole systems are meant to let water that gets behind the cladding escape and to promote air movement so the wall dries out. The spacing of those openings is chosen so moisture has a clear exit path across the entire wall area without pooling behind the veneer. A 24-inch maximum is a common, practical standard because it provides reliable drainage and drying without adding excessive cost or labor. Spacing smaller than that would still work but costs more with little extra benefit in most cases, while spacing larger than 24 inches risks leaving moisture trapped and can lead to staining, efflorescence, or mold growth.
