How close must a foundation vent be to each corner of the building?

A foundation vent must be placed no more than 3 feet from each corner of the building to ensure adequate ventilation in enclosed crawl spaces or foundations. This rule is essential for promoting airflow and preventing moisture buildup, which can lead to mold growth and deterioration of building materials. By installing vents near the corners, it allows for better cross-ventilation throughout the crawl space or foundation, ultimately enhancing the longevity of the structure. Adhering to this requirement helps maintain a healthy environment beneath the building and reduces risks associated with excess moisture.
