You must pay or contest your parking ticket within 20 days of the date the ticket was issued. If payment is not received within this time, the ticket will be considered delinquent and late fees will be added. If your citations remain outstanding, you may be referred to a collection agency, which will impact your credit rating.
If there are more than 3 or other outstanding citations, a seizure warning notice will be issued, and a boot may be placed on your car, and won't be removed until all outstanding fines are paid. If a vehicle is booted for 72 hours (excluding weekends and holidays) without payment, it will be considered abandoned and towed to impound.
