🚫 Common Deck Permit Mistakes in Green Bay

• Not opening footing holes for inspection before pouring concrete — major fail
• Ledger board attachment not properly flashed — #1 deck failure point
• Using non-approved hardware (galvanized vs stainless in coastal areas)
• Guardrail balusters too wide — 4-inch sphere rule strictly enforced

💡 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
• Check setback requirements from property lines before designing — some cities require 5-10 feet from property line
