[Limitless Decks]

Looking for a little help.

We designed a deck where the ledger board extends 4' past the corner of the house onto a 6x6 post and footing.

The local building official put a note into our plans that says the following "ledger board has turned into a beam. Beam is required to be supported by wood/metal/concrete. Not lags."

We've built many decks with this same design and have never had another city inspector bring this up.

I've searched the web and can't find any info.

I want to know if my plans are indeed wrong, or if the building inspector is taking this too far.

Thanks

They are correct but for the incorrect reasons. There are no prescriptive designs for decks (unless you count the DCA) where there's a cantilever or projection of the ledger into open space. It needs to be designed by a professional engineer. Did one similar just this year. Not sure if the building official wanted it engineered or the GC was just more aware than most.

Westbury sounds familiar, too.

I agree with lexpatrie - it's not that it can't be done as you've shown, it's that it falls outside of the scope of prescriptive design and requires a registered design professional to provide a sealed design before it goes to plan review.
