Vent/Waste Spec on corner sink

I am installing a corner sink in the kitchen. This puts the sink drain further away from the wall. Can someone tell me what the standard requirements are for the vent lines and waste lines?

I am wondering how far from the trap the vent can be? and any other requirements I need to keep in mind.

Also I plan to bring the waste line up through the floor about 5 inches away from the wall. The line will continue up and pick up the waste from the sink with a sanitee connection (seem ok?). From there I need to angle over into the wall. Are there any requirements here.

Specifically is there a minimum requirement of vertical run before putting in the 45 degree section to take the vent line into the wall?

Thanks in advance.

Trap arm for kitchen sink min of 1.5"
Distance for arm to vent 3'6"

Now the waste line has to be 2" but the trap arm and vent only needs to be 1.5"

If you make the trap and trap arm 2" then it can be 5'

You can offset that 45 degree and any point on the line.

Also you need to install a cleanout on that line, I put mine just below the trap or sometimes on the trap arm I will put on a wye with a clean out adaptor and a plug.

These codes are UPC

This may or maynot be what code your state follows, so also check your local codes, for I maybe telling you wrong.
