💡 Pro Tips from Contractors
- Open footing holes for inspection BEFORE pouring concrete — this is the single most common deck inspection failure
- Submit complete plans upfront — missing ledger board details or footing depth is the #1 reason for permit delays
- In coastal or wet climates, use stainless steel hardware (hot-dipped galvanized minimum) — inspectors check this
