When Railings Are Required
Most residential codes require guardrails on decks more than 30 inches above the ground, typically at least 36 inches tall with balusters spaced so a 4-inch sphere cannot pass through. Check your local code.
Choosing a Style
- Wood: cheapest, matches wood decks
- Aluminum: low maintenance, slim profile
- Cable or glass: keeps the view open
