I have a deck off the back of my house that is 10x12 (10’ depth, by 12’ width). I would like to extend the deck’s width by 7’. To accomplish this, I was thinking of pouring new footers, offset by a few inches with the other footers, and sistering the new beams to the original beams. I figured the footers would have to be offset a bit, as the beams would be off by an inch or so. I would then install the additional 7’ ledger, use new joists for the new portion, etc… Is this a kosher way of doing an extension? Or am I better off installing the new footers inline with the old, taking down the complete deck, and install everything from scratch? I am not sure if tying the two decks together is kosher.

Thanks,

I would isolate the two decks, but build them in proximity to one another.
I'd move the footings away from the original footing by at least 2 feet.

re: extending deck

To be more descriptive, I am extending it in a trapezoidal way... 7.5 feet at the base, then 5 feet out from the house, then connecting to to a point at the top. So it turns out to be a small triangle extension... so I am not sure how extend it. I think I need to post a picture of what I plan for it to make sense.

You would attach a ledger to the house and support posts where you need them. Still no need to physically connect it if you don't want to.
It depends on how the current deck's structure is set up.

I think you should also consider this options to fulfill your requirement.
