I am installing new flooring in a condo.
The condo association removed the old floor heating in favor of vent heating.
However, the copper what I assume to be gas lines (or water lines are sticking out of the old floor slightly and I want to cut them flush and install the flooring right over them.
Is there any code I am violating by doing this?
A few things to check;
Did you place the expansion tank on the cold water side?
Did you pressurize the expansion tank to the same pressure that the water line is at after the regulator?
Is the expansion tank size rated for the size of your hot water heater?
As Keshlam commented (hence this answer is community wiki), An oscillating multitool is a good choice. You can probably rent one if you don't want to buy one. I would practice on some scrap wood.

That pipe is already left open and surely not active or charged. Cutting it again will not be a problem, since it is no more than cutting it again slightly lower than what it is already.
If you want to go the safest route, since the floor is being redone anyway, remove enough of the existing floor to cut it below the existing floor to place a self sealing cap over it like Sharkbite (r) or similar brands. Please note, to do this the cut needs to be cleanly done, in order for the seal to be effective.
