North Carolina Building Contractor License Practice Exam

How far apart may non-bearing walls be framed?

1. 8 inches on center

2. 12 inches on center

3. 25% to 40% of spacing

4. 20 inches on center

The correct answer is: 25% to 40% of spacing

Non-bearing walls are typically framed with specific spacing that allows for structural integrity while not supporting any loads other than their own weight. The correct choice reflects that the spacing for these walls can be determined based on a percentage of the spacing guidelines for structural members, which provides flexibility depending on the wall's function, materials used, and other design considerations. This percentage approach allows for adaptability in building design, as it takes into account various factors like wall height and the materials used. Non-bearing walls often do not need to conform to the more rigid spacing of load-bearing walls, giving builders some leeway in determining spacing based on the specific requirements of their project. The other options present fixed measurements for framing spacing, which may not take into account the versatility needed for non-bearing structures. Non-bearing walls don’t require standard spacing measurements like those used for structural members, allowing for this percentage-based approach. Thus, understanding this aspect of non-bearing wall construction helps ensure appropriate framing practices that adhere to building codes and standards.
