Im trying to find a code reference for this. The builder of my house nailed

It leaks and I want to get them to fix it. If I had the code reference Id
be going in there with something to argue. Since Im the second owner of
this six year old house Im not sure if they will fix it or not.

That's definitely hosed up. The siding should end about 3/4" to an inch above the roof plane and the flashing should extend up a couple inches behind the siding. No caulk. You could take some pictures, take it to the building department and ask their opinion.
