The 3/4/5 rule in deck building is a fundamental guideline for ensuring structural integrity, particularly for ledger board attachment. It refers to the spacing of bolts or lag screws used to secure the deck ledger to the house. Specifically, for a standard ledger board, you should place fasteners in a pattern that follows a 3-inch, 4-inch, and 5-inch vertical spacing from the top of the ledger. This staggered pattern helps distribute load evenly and prevents wood splitting. For professional compliance, always verify local codes in San Jose, Santa Clara, or Sunnyvale, CA. At Lecut Construction, we emphasize that this rule is a starting point; actual fastener spacing must be adjusted based on joist span and ledger thickness to meet safety standards.
