  1. 4

  2. 6

  3. 8

  4. 10

The correct answer is: 6

The correct answer is that footings for masonry chimneys must extend a minimum of 6 inches beyond the face of the foundation or support wall on all sides. This requirement is primarily in place to provide adequate support and stability for the chimney structure. The extended footing helps to distribute the load of the chimney more evenly and reduces the risk of cracking or settling, which can lead to structural issues. Additionally, by extending the footing beyond the foundation wall, it decreases the potential for water infiltration and provides proper drainage, which protects both the chimney and the foundation from damage over time. In terms of building codes, specific dimensions like the 6-inch extension ensure that construction practices meet safety standards while enhancing the overall longevity of the structure.
