Tips

  • A new or replacement deck now requires a building permit specifically to confirm Wildfire Resiliency Code compliance for applications on or after July 1, 2026 — factor this into any deck project timed around that date.
  • If your deck design includes a retaining wall over 4 feet, budget for a separate engineering letter and possibly a safety railing requirement.
