I do prescriptive structural design for stuff like this, and I would have to know the plan of the platform before giving any code advice on a small aspect like this.

You have an odd story for a GC.

Why? The way i read it, he is talking with the customer about additional, new work, and he saw this existing framing. He is concerned about the previous work and doesn’t want to get his name attached to something that doesn’t meet code or is unsafe. Sounds like good due diligence to me.

Maybe it's just me.
Doesn't sound like an experienced contractor's approach to the situation.

It's not the way I, or other Experienced GCs I know, would handle the problem.

Let's not overthink this here. Couple cases of beer and some fat chicks to give'er a test run.

Performed a walkthrough with a potential client and came across this framing of floor joists/wall connection. Previous contractor says it’s to code, however, I believe it violates R502.6 Bearing as there are no brackets to connect to the rim joist to transfer load to wall and the horizontal 2x4 is not a proper load transfer point as the joist is not nailed to the vertical 2x4 stud(possible attempt to perform a ribbon strip?). Looking to assist with further explanation on the violation.

Are there any other violations that can be elaborated on? Thank you for your help!


R502.6 Bearing
The ends of each joist, beam or girder shall have not less than 1½ inches (38 mm) of bearing on wood or metal, have not less than 3 inches of bearing (76 mm) on masonry or concrete or be supported by approved joist hangers. Alternatively, the ends of joists shall be supported on a 1-inch by 4-inch (25 mm by 102 mm) ribbon strip and shall be nailed to the adjacent stud. The bearing on masonry or concrete shall be direct, or a sill plate of 2-inch minimum (51 mm) nominal thickness shall be provided under the joist, beam or girder.

Ouch!
That was my first expression seen this picture!
The floor joists (2x10 ?) need to sit at least on half of the width of the top plate 2x4s!
in this picture the load is primarily transferred and held by the screws or nails!
My golden construction rule philosophy is in general is "a proper framing can stand/hold any load on its own" and the fasteners ( nails, screws) are merely the "placeholders" so nothing can move away and stays where it's supposed to be. No load should ever go over a fastener unless otherwise specifically designed i.e. joist hangers.
In other words, any load and stressors must flow through the lumber and not rely on just a few nails at the edge of the wood to be transferred onto another lumber! split-y-split... collapse...
the floor joists stress/load flow in the picture rely mostly on the tacked on 2 x 4!
Imagine this: increase the load on the floor in theory and imaginative with a hydraulic press. or any weight. Imagine increasing the pressure to half a ton, to a ton, to 2 tons and so on and so forth.
What's gonna start moving?
the floor joist nailed into the header joist will pressure the 2x4 its sitting on and gradually bending pulling out the nails subsequently all nails from the header joist as well!

Do an image search for "floor framing" and you will see the correct way and what I mean!

I have been under the belief you needed 2" of bearing ,not 1 1/2" .

The OP quotes the code paragraph. I wonder why masonry and concrete require double.

 

[Leo G]

Looks like someone missed their length measurement by 1.5" and thought that putting a 2x4 there held up by only nails would be adequate to hold that load.

 

[Calidecks]

Add another 2x4 wall next to the other one. Done.

One time I saw that "ledger" board stacked with 4-5 two by eights. So the joists attached to the stack instead of sitting on the foundation.

I don't know why it was like that. But quite crazy. The house has many issues. And once upon a time was renovated by a prominent area EC and Is GC brother. The EC was the owner with big dreams...

That is not platform framing. It’s called bad framing.

Always perform a walkthrough before attempting to perform a ribbon strip.

Were you able to elaborate on other violations?
