Utility areas are areas of the prison that are non-essential but can hold prisoner stashes and ladders to vents. These are accessed with a utility key, tunneling, wall breaking, or/and using vents. The guards will not search this area unless they see you in there. They also will search the area if the notice any contraband lying on the floor or any damage dealt to the prison (e.g. hole in the ground, broken wall or missing vent cover). If they see you in there you will go straight to solitary confinement if there is a chipped wall, tunnel, or missing vent.
