The EOS lab is open 24 hours a day, but parking on campus is not allowed between 3:00 am and 7:00 am. A parking policy has been implmented to overcome this discrepency. There are two situations: You live off campus: You MUST have a student parking permit You MUST get an overnight parking pass (valid only for that night) from Public Safety. If you do not have a student permit, you are allowed 20 visitor permits per academic year. The overnight passes will count against these days. You can then park ONLY in lot C for the night. You live on campus: You must park in resident parking (Lots D & B are the lots closest to MAK). You CANNOT get an overnight pass for Lot C.
