Unfinished Basement - Exposed Romex

If installing outlets on block walls of an unfinished basement, is romex permitted or must conduit / MC cable be used?

I think it is local code issue. If you check with your local codes official they should be able to tell you. At the very least you will need running boards mounted to the block walls to staple your romex to.

Are you going to finish the basement or not? A nice secure way to do that is to take some emt and deep handiboxes and a few 4x4"s and get some 3 wire also. Anchor the box well and strap up on the floor plate. Cut the pipes in half. Then its good if you dont finish it and good if you do. That protects the wire well till its up in the joists. A little hammerdrill would be helpful to mount boxes and clamps.

Ordinary Romex is allowed where "fished in air voids in masonry block or tile walls" according the 2002 NEC article 334.10(A). However, you may not install it on the surface of those walls without additional physical protection (e.g., conduit).

There could also be a local code that dictates the height of the boxes from the floor.

Don't forget ground fault protection for receptacles in an unfinished basement.
