Virginia Building Code Requirements
- Railing required: On any deck surface 30 inches or more above grade
- Minimum height: 36 inches (some Fairfax County areas require 42 inches for decks over 30" above grade)

- Graspable handrail: Required on all stairs — 1.25" to 2" diameter, continuous
- Cable rail: Maximum 3" spacing between cables, must pass 200-lb load test
HOA note: Many Northern Virginia HOAs have additional restrictions beyond building code — specific railing profiles, colors, or style requirements. We check your HOA guidelines before recommending a railing system. Read our HOA guide.
Choosing the Right Railing for Your Deck
For a view deck (elevated, scenic lot)
Cable rail or glass panels. Both maximize the view and create a modern, open feeling. Cable is more affordable; glass blocks wind.
For a traditional home
Composite or aluminum railings in white, bronze, or black. Match the home's trim color. Trex Signature in Charcoal Black is our most-specified option for colonial and transitional homes.
For a pool surround
Glass panels (meet most pool barrier codes) or aluminum with self-closing gates. Check your county's pool fence requirements — they're separate from deck railing codes.
For budget-conscious builds
Aluminum railings offer the best value for a modern, maintenance-free look. $35–$60/linear ft is significantly less than cable or glass, with zero upkeep.
