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.
The primary cause of 90% of deck collapses is the failure of the connection between the deck ledger board and the house structure. This critical joint often pulls away from the home due to improper fastening, corrosion, or wood rot. Many decks fail because builders use inadequate nails or screws that cannot withstand the weight and weather exposure over time. To prevent this, it is essential to use through-bolts or lag screws with proper washers, and to ensure the ledger is flashed correctly to avoid moisture damage. Regular inspections by a professional, such as those offered by Lecut Construction, can identify early signs of weakness before a catastrophic failure occurs.
