Plumbing: Does a drain for a bathroom sink have to approach from the back of the sink?

OR can I re-route the drain to enter from the side?
My bathroom sink is located in a corner with the back to an outside wall. The builders installed the the drain pipe to come up through an interior wall to the right hand side and turn the corner 90 degrees to get into the outside wall so that the drain could approach the sink from the back. This sink clogs constantly due to all the angles - I have to remove the trap and clean the pipe in the wall every four months and the smell from the pipe clog is horrible, like straight sewer gas. I would like to know that if I tear off the drywall and route the drain to come from the interior wall straight to the drain, to remove the 90 degree turn in the outside wall, if it would still meet code?

In the picture the Pink represents the CURRENT drain and the white tape represents what I want to do.
the house was built in 1979 and I don’t know what they were thinking when they did this.

How can I install a new vanity with two sinks into a bathroom that presently has only one sink? ?

Space is not the issue–I just don’t know if I need to have additional plumbing installed or if it is something relatively easy I can do myself. Any one know? Thanks.

I am getting an earthy smell from my main bathroom sink drain. House is 2 years old. How do I get rid of it?

Out of the blue, my main bathroom that guests primarily use starting having an earthy smell coming from the sink drain. It’s on the main floor, and there are no floors above it (in other words, not another sink above it). I examined the plumbing under the sink, and everything seems to be in working order, no leaks, trap is in good shape, etc.

What should I do here?
