I keep seeing this in my area (mountains of Colorado), even on new construction and my instinct is that it is not best practice for ledger board connection. From my training, I’ve always seen staggered bolting to distribute the load and minimize chance of splitting.
I’m referring to the three vertical stacked lags in the attached photos. This is just one example but I keep seeing it.
Am I right about this and would you consider this a safety concern/defect or simply not best practice construction?
