Rate Maximums
  • If you pay for parking during the day and reach your $8 max, there is no additional charge if you park for the rest of the evening.
  • If you begin your parking session before 4:30 p.m. and do not reach your daily maximum, your rate per hour will switch over to the evening rates after 4:30 p.m. You will not pay more than the $8 daily maximum.
  • If you begin parking after 4:30 p.m., you will pay the evening rates and you will not pay more than the $3.75 evening maximum.

  • You must display your permit AND pay via phone, web, or mobile app to park lawfully. You must create an account with ParkMobile to pay for parking.
  • You are responsible for:
    • knowing the lot’s hours and being in paid status during the lot’s hours of control,
    • using the correct location code, and
    • paying for the correct license plate.

You cannot retroactively pay ParkMobile for missed payments.

A Flex permit is valid in your assigned lot only between 7 a.m. and 4:30 p.m. on weekdays. Outside of those hours and all day on weekends, Flex permit holders can use their permits in certain other campus parking lots. A Flex permit may be used in “controlled at all times” lots when they are open to any valid UW permit (4:30 p.m. – 7 a.m.), but the permit must be displayed and the vehicle be in paid status using the zone code from your primary lot. If a lot is open to the public after enforcement hours, payment is not required.


If paying online or in the mobile app, the system will prompt you to choose the number of hours to park OR to select the daily maximum. If you intend to park 8 hours or more (for sessions beginning before 4:30 p.m. on weekdays OR >5 hours after 4:30 p.m. on weekdays/weekends), it is important to select the daily maximum to be shown in paid status beyond 8 hours. If you select a flat 8 hours, you are only in paid status for 8 hours from the time you start the session.

When paying over the phone (not via the app), the system will tell you the max number of hours available to park. Select the maximum if you intend to park beyond the lengths of time described above.

Flex Parking Lots and Payment Codes

You can also find Flex lots and codes on the Flex parking map. Hours of control are on the lot locations and hours page.

The number of permits available in the per parking year is intended to help those applying decide which lots to select and which priority order to apply. The number does vary from year to year based on construction projects, demand, etc. Reminder: Flex is a very popular program, with permit allotment per lot reaching its max early in the parking year. Waitlists can be lengthy!
