I'm having issues with my object with the subdivision surface modifier. I can't seem to find what I'm doing wrong. It creates overlapping faces that I can't edit.

    $\begingroup$ You probably have ngons around the "hole". You need to isolate it with proper quad mesh part. $\endgroup$ – lemon Mar 21 '18 at 15:24

You are probably in this situation:

The problem is due to the ngons surrounding the hole: they are not easily processed by the subsurface modifier, so you need to change them into quads.

enter image description here

  • Enter edit mode
  • Set mesh select mode to "face" CtrlTab
  • Select the ngons
  • Triangulate CtrlT
  • Make quads AltJ (reselect and redo it as needed)
  • There is some glitches at the corner
  • So surround the hole CtrlR
  • And adjust the position of the surrounding section
