Signs in the Public Right-of-Way

Holding a Fundraiser?  Planning a Garage, Yard or Estate Sale?   Advertising your Business?

No matter the type of fundraiser, sale or business, remember that State law prohibits the placement of signs in the public right-of-way.   Please keep in mind:

  • Do not attach signs to any traffic control devices such as signal poles, signal boxes, or signposts.
  • Power poles and fences are usually located on or near the right-of-way lines and are a good reference for the width of the highway right-of-way.
  • On improved county roads (those roads with paved shoulders, generally 40 feet or more in width, and where no fences or power poles exist), use 50 feet from the centerline as a guideline for placing signs.
  • On unimproved county roads (those roads approximately 22–30 feet in width), use a distance of at least 33 feet from the centerline for the placement of signs.

For specific right-of-way width determinations, Anoka County has a GIS map available online that shows property lines and plat information, which can help in determining the right-of-way widths. There also is an aerial view to allow you to have some actual reference points on the ground to assist you. This information can be found at

We realize the use of signs is a vital part of your successful fundraiser, garage, yard or estate sale, or your business!  If in doubt of the highway right-of-way boundaries, please contact the Anoka County Highway Department at 763-324-3100.
