Hi all, long time lurker first time poster here. Thanks for all the advice so far!

Is the proposed (drawn) layout combined with the venting specs (2nd diagram) okay for a new bathroom in California? The only wall I have to work with (for venting) is the one behind the fixtures because the one across from them is positioned exactly over a large beam in the crawlspace. The new ~30' run of 3" that ties into the existing drain line is pretty well fixed horizontally by piers and other obstructions in the crawlspace.

1. I know this could probably be more efficient with wet venting and less turns, but is the proposed layout of concern?
2. Are the amount of horizontal turns of concern?

Note: Not drawn, but there would also be a CO to serve the new pickup line perpendicular to where the shower enters

Hey, wait a minute.

This is awkward, but...
