Is an offset toilet flange legal in Virginia?

According to the buyer, the basement is to be finished.

My biggest concern is the lack of gravity being in a basement.

I could accept this more easily if it was on a first or second floor, but being in a basement, I am envisioning frequent clogs.

I still feel that if the floor is open, why not nip it in the bud while you can.

I appreciate the responses!

Thank you all

Tom
