Help with fire code in a condo building
Generally fire code will require that any exposed wiring (not run through metal conduit) be behind sheet rock or some other wall board.

I would imagine the same is true for plumbing.  

The logic here is that you can't pull, bump or otherwise disrupt wires and pipes if they are behind a wall.

I don't know the particulars of code in MSP BUT I can't imagine that they allow exposed pipes and wiring.
