It is always possible to make room for one more student at ND. It is by definition never physically full. It is only logically full -- an artificial number where they decide to not allow others in, but not tied to physical space. They can by definition always make a senior move off campus, so it never is full. But, it virtually never comes to that because there is always attrition during a year, rooms opening up, and my freshman year they used every single study lounge in Grace Hall to hold 6 per floor, 11 floors -- for example.

There's a much higher percentage of students living off campus now than before too -- upwards of 10% now versus 1-3% circa 1989. The point being it is even easier now than before to shift people off campus if needed.
