How do I know if I can install a pocket door? It's on an inside wall, not a load bearing one, but before I rip out a wall what should I be looking for?
The current doorway is 24" wide and swings into a very small bathroom. Putting in a pocket door will add a tonne of space but how do I know if it's doable?

Thanks

I would check for any electrical, TV or telephone jack that may be currently in the void.

Retro-fitting a pocket door to an existing wall is fairly destructive, to the wall. Before you start do as Stratmando suggests, loook for outlets, light switches, air ducts or any other jacks. You will prettymuch destroy a 24" plus opening on one side or the other, pick the one that is easiest to repair.

I'm okay with some destruction. How do I know if I can do it? There doesn't appear to be any electrical or duct work. Are there structural issues that I need to watch for?

Unless this is a load bearing wall you will find few structural issues. Are you 100% positive this is not a load bearing wall?

93% :) I'm a total novice to home repair stuff. I have a small house: There is one wall runs the length of the house. The other that I want to put the door into runs parallel to that one but for only 1/3 the length. I assume it's not load bearing?

Does not sound load bearing. When you start your tear down first open the header above and around the old door. If it is carrying any load you will see a double 2x10 header supported on double or triple studs.
