Railing Code Requirements in Georgia

Georgia building codes have specific requirements for deck railings that apply regardless of material choice:

  • Height: Minimum 36 inches for residential (42 inches for commercial)
  • Baluster Spacing: Maximum 4 inches between balusters (so a 4-inch sphere cannot pass through)
  • Graspability: Top rail must be graspable if deck is more than 30 inches above grade
  • Load Requirements: Must withstand 200 lbs of force at any point
  • Required When: Deck surface is 30+ inches above grade

Always check with your local building department as some jurisdictions have stricter requirements.
