The 25% Rule for Florida Window Replacement Explained

How The 25% Rule Works In Practice

Why Florida Uses This Threshold

The rule exists because Florida does not treat windows as decorative items. They are part of the structure's weather defense, and once enough of them are replaced, the code expects the new openings to perform to current standards.
