Applications & Forms

Sign permit applications, specifications for electronic message centers (EMCs), and submission instructions are available from the City of Duluth permit or planning pages; check the official sign permit page for current forms, fees, and submittal methods. [2]

  • Permit name: Sign Permit / Electronic Message Board application (official form; fee and submittal details on the permit page).
  • Fees: fee amounts are published with the permit form or fee schedule; if not listed, the fee is not specified on the cited page.
  • Deadlines: typical permitting timelines and review periods are on the permit page; specific deadlines may vary by application.
  • Submission: most sign permits require drawings, brightness specifications, and electronic content details; submit per instructions on the official application page.
Always include brightness specs and control settings with your application to speed the review.

How the Rules Typically Work

Municipal sign rules commonly set a maximum luminance for digital displays (measured in nits or foot-candles), require automatic dimming at night, and limit content transition speeds (for example, minimum seconds between full-message changes). Where Duluth specifies particular luminance values or rotation timing, those figures appear in the sign standard or permit conditions; if a numeric standard is not present on the cited page, it is noted as not specified. [1]

  • Brightness controls: automatic dimming or maximum nit levels may be required by permit conditions.
  • Content rotation: minimum dwell time and transition rules limit rapid animation and flashing.
  • Visibility and safety: restrictions often exist to avoid driver distraction, including prohibitions on full-motion video in some zones.
