We have a facility that is a detoxification center for youth that has a number of secure rooms for several weeks stay for each patient/detainee. There are controls for the space but each room has very limited control for obvious reasons. 

If this space consists of the 50% of the required occupant space needing control, can this credit in this situation be acceptable? And does the control requirement only apply to Option 2 or is it for the entire credit?

Some guidance would be appreciated.
