Two quotes from the most recent article:
1) “the young men were struck in the dormitory driveway”
So yes, no sidewalk, but they wer not on the road.
2) “The property was granted a permanent certificate of occupancy as a school and dormitory in February 2016, and all of its inspections are current, Ramapo’s Chief Building Inspector Anthony Mallia said in an email.”
So C of O not relevant by any stretch.
