Parking permits may be canceled at any time during the year. To cancel a permit, the permit hangtag must be removed from the vehicle and returned along with the AVI responder (if issued) to the Transportation and Parking Office, 3401 Walnut Street, Suite 447A. A pro-rata refund will then be processed or payroll deduction canceled, based on the date of receipt of these credentials. Payroll deductions will not be removed until the credentials are returned. Please notify the Parking Office if the credentials cannot be returned immediately.
