According to Code, foundation plates or sills shall be anchored to the foundation with bolts spaced not more than _____ inches apart?

• A. 32 inches
• B. 96 inches
• C. 48 inches
• D. 72 inches

Answer: (D)

Foundation members must be firmly tied to the concrete or masonry below to resist forces that try to lift or slide the building. Anchoring the foundation plates or sills with bolts transfers load from the wood framing into the foundation, so the connection stays intact during wind, seismic, or seasonal movement. The rule sets a maximum spacing: bolts should not be spaced more than six feet apart (72 inches). This limit ensures there’s no long unanchored run along the sill, which would be vulnerable to uplift or movement. Using a smaller spacing, like 32 or 48 inches, would still meet the requirement, but the question is asking for the maximum allowed distance, which is 72 inches. A spacing of 96 inches would exceed the limit and isn’t permitted.
