Temporary permits are available online -- a credit card is required. The permit is issued as a printable PDF. If the permit shows the license plate of the vehicle you are driving, you may enter and exit the facility by scanning the QR code of the permit on your smartphone. If the permit does not have a license plate number associated with it, you must display the permit on your dashboard.
Temporary permits are available in limited facilities around campus. Check the campus map to ensure the permit you purchase will meet your needs.
