New Construction

Swing-away mailbox settings are required on the County Highway System for any new home construction that will have mail delivery service. Sherburne County offers for sale (only if located on a County Road / CSAH) approved MnDOT settings for $75 and will install them free of charge.

Mailbox Notes:

  • A right of way work permit is not required for a mailbox.
  • You may construct your own swing away setting; however it cannot weigh more than 4 pounds per foot.
  • Bulkier and heavier settings may compromise public safety and constitute a right of way violation.
