Double sink drain piping

[John McC]

Hello, I am doing a full remodel of my bathroom (down to the studs) and will be replacing the existing single-sink vanity with a double vanity. I am proposing to pipe the drain as shown in the attached image but I am not sure about how to properly vent it. I've been searching for similar examples online but they all seem to be slightly different so I am not sure how to do it and that's why I'm here.

As shown in the image, can I get away with only one AAV by the sink farthest from the main line or will I need an AAV for each sink? Or is that completely wrong and I should do something different all together? The reason I'm going vertical from the branch is because the new vanity is taller with top-mounted sink bowls so I need to go up a bit.

For additional clarity, I should mention that the Front view shows what would be inside the wall and the Side view shows both in the wall and under the sink. Ignore the 90deg bends because I have the IPC code to know what fittings I'll need for the changes in direction. I was just trying to complete the sketch quickly.

Thanks,
John

Its not code for IPC

Thanks for the response but I'm not sure what you mean. I'm just looking for suggestions on how to properly pipe my new sink drains.

You need a vent after each of the 2 traps before the lines drop vertically, to prevent siphoning.

Here’s one I did but I took this picture before I finish strapping and bracing, you’ll get the idea though.

Those metal studs didn't know what hit them.
