cantilevered ledger board


I am adding a new deck that has only 50" of wall ledger and two posts at the other end. This will be nestled in a 50" nook at the corner of the house. I would like to extend the deck 2' out, and was wondering if I could do this with the ledger board. I will then have 50" + 24" of deck, using only 2 posts and 50" wall ledger space. Do I need to sink a third post?

Kind of following you but not quite. Hopefully I'm following and this helps.

If your ledger board is extending past the house (becoming a cantilever), you will likely need a post in that corner to support the additional weight because it wouldn't be supported by the house.

Example: If deck weighs X lbs and that is distributed over a 50" ledger at one end of the deck (and distributed over a beam and 2 posts at the far outer end of the deck), if you extend the deck ledger past the house, you now have the original deck weight of x + additional 24" of weight distributed over the same 50" ledger.

If the deck is small and the ledger is larger than minimum code for your area, it may be alright (hence oversized to carry the load). Personally, I'd draw out what you want to do and stop by your building permit office. They will be able to tell you if this passes or not.

Good luck.

Just had the same situation. Yes, another post supporting the cantilever is required.

So does this mean the ledger board can extend past the house with the third post to meet it?

What did the building inspector say about it when you asked him?

I'll try to be more clear...its my experience that a third post will be required to support the cantilevered end of the ledger board.
