Parking on Campus

• The campus has two kinds of visitor parking spots: meters (few in number and really only good for very short stays) and pay station spots. There are two nearby pay station locations, both shown in the map below in color.
• Paint Branch Drive Visitor Lot, labeled 'P' on the map below.
• Regents Drive Garage, near the Fieldhouse Drive entrance.
• Weekdays after 4pm and all day Saturday and Sunday parking is free for everybody at many unrestricted lots. Do NOT park at a parking meter! Double check the sign at the entrance of the parking lot!
• If you are an official department visitor (such as a seminar speaker) and the department has promised to pay for your parking, make sure you get an 8-digit PIN from the department for use at the pay station. This will cover your parking for a full day.
