The 3/4/5 rule is a widely used guideline in deck construction for determining the proper spacing of support posts. It states that for a deck ledger attached to a house, the maximum cantilever (the overhang beyond the last support beam) should not exceed 3 feet. The maximum span between support posts is 4 feet for 2x6 joists, 5 feet for 2x8 joists, and so on, depending on lumber size and load requirements. This rule helps ensure structural integrity and prevents sagging. For professional deck projects in San Jose, Santa Clara, or Sunnyvale, local building codes may have specific requirements. Lecut Construction always recommends consulting a structural engineer or your local building department to verify that your deck design meets all safety standards before construction begins.
According to industry safety studies, approximately 90 percent of deck collapses are caused by the failure of the ledger board connection to the house. This critical structural component bears much of the deck's weight, and when it is improperly attached, rotted, or flashed incorrectly, the entire structure can pull away from the home. Other contributing factors include inadequate footings, poor soil conditions, and the use of undersized hardware. Homeowners should schedule regular inspections of the ledger, joists, and fasteners to catch warning signs early.
