90's below the rim of the sink doesn't meet IPC code. I know much of California is under a different code.

Hmm... So, out the wall and attached to a sanitary tee then... Do they make a sanitary tee that goes from 1-1/2" from the side and going up but 2" going down?
Yes, a 2" x 1 1/2" x 1 1/2" sanitary tee. The first number notes the outlet, the second number the run inlet, and the third the branch inlet.
Thanks, phishfood! I'll take a note to look for those dimensions next time I hit the hardware store. Then comes the fun of figuring out how to get the outside one at the proper angle so it goes next to the window without the 90 underneath.
