Framing a Deck? Is this ok, if not how can I make it right

I recently saw a deck that I believe is not framed correctly. I enclosed an attachment including two options. I believe option B is the typical way to frame a deck, but this deck was framed like option A. I don’t believe this is correct, and it didn’t have a beam, etc, just footers in the same locations as option B.
I’m concerned that the framing is parallel to the house. I don’t believe this is acceptable, please advise.

Deck Framing
You are correct, option B would be the standard way of building the deck. To make option A work you would need to make the rim joists and the center joist into beams and add joist hanger to the other joists. As well the beams would then need to have hangers tied into the ledger against the house.
Agree
I would agree with your assement. That outside cantilever would be a weak point without the three perpendicular joist becoming beams. If the outside band joist however, sits on top of the footing piers it would be ok.

What was the size of the framing and are the joists and band all single members? Any joist hangers used?
What do you find wrong with framing direction paralell to the house?
2x10 construction, with hangers used between the parallel joists and single band joists. Everything is single banded.
After reading what I posted, I think I misrepresented my question/concern. I wasn't concerned with the framing parallel to the house, it was that all of the members were single banded, and I didn't believe the each of the two Options (as drawn) allowed for single banded members.
With proper connections either is fine.
Structurally, with properly sized members, and the right connections, either orientation is fine.
How you orientate things is just a matter of how you want the sight lines to run.
Either one should work with proper framing. Just depends on how you want the deck boards to run. (Parallel to the house or perpendicular)
It can be framed either way if done correctly. Neither of the options you showed are correct, though.
care to elaborate any further on your correct comment.
Would like to hear your opinion.
In both options you posted, the perimeter joists should be doubled. In option A, the center member should be a carrying timber/beam. It may just need doubling up or it may need to be larger, depending on size and weight of the deck. Neither shows specifically where, how posts from the sona tubes/footings connects to the deck. In both cases, a dropped carrying beam could be used underneath the deck joists, and/or under the center carrying beam in option A. This would make up for difficulty in keeping posts and footings aligned precisely with your chosen attachment points. I can't see your original post while writing this response but I don't remember seeing any details of how either option would be connected to the footings, what the footings are, how large or deep. This can change the necessary framing and supports. Carrying beams would need to be sized for the spans between footings. There wasn't any info of what was being used for framing lumber, I guessed typical 2x material. My response could be different if large framing members are being used.
