Portable Signs

  • All companies that rent portable signs to customers within the city must be licensed with the city and carry liability insurance in a form and amount specified by the city. Each rental sign shall have the rental company's name and phone number clearly visible on the sign.
  • No-cost registration of portable signs is required along with a monthly update on the location of each sign.
  • A portable sign may be placed at a business up to 240 days per year.
  • Portable signs include parked trailers or vehicles visible from the right-of-way unless used in day-to-day operations.
  • If having a portable sign out for more than 240 days is not enough for a business, the Mandan Architectural Review Commission encourages the business to switch to a permanent sign with changeable copy.
