California Residential Inspector Practice Exam

What is the permissible percentage of shear wall length that can be accounted as openings?

1. 10 percent

2. 15 percent

3. 20 percent

4. 25 percent

The correct answer is: 20 percent

The permissible percentage of shear wall length that can be accounted as openings is 20 percent. This figure is significant in the context of building design and structural integrity as shear walls play a critical role in providing lateral support to structures, especially in areas prone to seismic activity like California. When designing shear walls, it is essential to limit the size of openings such as windows and doors to maintain the wall's structural integrity. Allowing up to 20 percent of the wall length to be openings recognizes the need for functionality and aesthetics in residential design while also ensuring that the shear wall can effectively resist lateral forces. This balance between structural requirements and design flexibility is crucial in ensuring the safety and performance of residential buildings, particularly during seismic events. While other percentages, such as 10, 15, or 25 percent, could theoretically be considered in different contexts or jurisdictions, the recognized standard for allowance in shear walls is set at 20 percent in California building codes. This standard reflects an understanding of how openings can be integrated into building designs without compromising the overall performance of shear walls.
