Residential Building Inspector Practice Exam

What is the maximum spacing requirement for anchor bolts in a crawlspace foundation?

1. 4 feet O.C

2. 6 feet O.C and within 12 inches of each end

3. 8 feet O.C

4. 10 feet O.C

The correct answer is: 6 feet O.C and within 12 inches of each end

The requirement for anchor bolts in a crawlspace foundation is that they must be spaced a maximum of 6 feet on center and placed within 12 inches of the ends of the sill plates. This spacing is critical for ensuring proper anchorage and stability of the structure, particularly in resisting lateral forces such as wind and seismic activity. By having this guideline, the building code ensures that the foundation remains securely attached to the superstructure, preventing any potential uplift or displacement that could occur during extreme weather conditions. Adequate spacing and positioning of anchor bolts are essential to maintain the integrity of the entire structure, making this requirement vital for safe construction practices.
