What the longest you've ever been delaying dealing with permits 🤔?!
What happens here
After the main beams are in place, the deck joists are installed. These typically run perpendicular to the ledger board and rest on or are attached to the main support beams. Joist hangers are used to secure them to the ledger board, while they might be toe-nailed or attached with hurricane ties to the beams. It's crucial to frequently check the entire frame for squareness and level using a speed square and a long level to ensure a stable and even deck surface.
Goal: Install deck joists and ensure the frame is square and level.
