California Residential Inspector Practice Exam

Under-floor access openings provided to under-floor spaces shall be a minimum size of what dimensions?

1. 12 inches by 18 inches

2. 16 inches by 24 inches

3. 24 inches by 32 inches

4. 30 inches by 36 inches

The correct answer is: 16 inches by 24 inches

The minimum size for under-floor access openings is crucial for ensuring safe and effective access for inspections and repairs in residential properties. The correct choice specifies dimensions of 16 inches by 24 inches, which aligns with standard building codes and practices that aim to facilitate accessibility while also considering structural integrity. This size is adequate for a person to enter the crawl space comfortably while maintaining structural support around the opening. Additionally, it allows for the movement of tools and equipment necessary for inspections or maintenance work. Choosing a size that is too small could hinder access and make inspections more difficult, potentially affecting the safety and efficiency of the work being performed. When evaluating the other options, while larger openings certainly provide even easier access, the specified dimensions of 16 inches by 24 inches meets the requirement set by building codes, ensuring compliance while also being practical for typical maintenance needs.
