Signs and Advertising Michigan 3 Minutes Read ยท published March 01, 2026 Flag of Michigan

In Dearborn, Michigan, digital signs and electronic billboards are regulated through the city zoning and permitting system to balance commercial messaging with public safety and neighborhood character. This guide summarizes where brightness and rotation rules are found, who enforces them, typical permit steps, and how to report a suspected violation.

Scope and key definitions

Digital signs include LED, LCD, and other electronic display technologies that can change brightness, color, or image. Rotation/animation covers periodic changes in displayed content, including slide transitions and moving graphics. Local rules distinguish on-premises signs from off-premises billboards; check permit conditions for allowed hours, brightness controls, and required dimming or automatic ambient sensors.

Where the rules are published

The city code contains sign standards and any municipal sign permit requirements; the Building and Planning divisions administer permits and inspections for digital signs. For the controlling text, consult the City of Dearborn municipal code and the Building/Sign permit pages for official application instructions and contacts: Dearborn Code of Ordinances - municipal code[1] and City of Dearborn Sign Permit information[2].

Penalties & Enforcement

Enforcement is typically carried out by the Building Division, Planning/Zoning staff, or Code Enforcement under the City code; complaints are accepted via the city contact pages linked in Resources. Specific monetary fines for digital sign brightness or rotation violations are not specified on the cited municipal code page and are listed as "not specified on the cited page" below where applicable.[1]

  • Enforcer: Building Division and Planning/Zoning; complaints/inspections initiated via the city's permit or code enforcement portals.
  • Fine amounts: not specified on the cited page.[1]
  • Escalation: the code does not specify a uniform first/repeat/continuing fine schedule for digital sign violations on the cited page; see the enforcement contact for case-specific penalties.
  • Non-monetary sanctions: orders to remove or disable noncompliant displays, stop-work or permit revocation, potential court action; the municipal code provides enforcement remedies but specifics for digital displays are not detailed on the cited page.
  • Appeals and review: appeals are usually through the city's administrative appeals or Zoning Board of Appeals process; exact time limits for filing appeals are not specified on the cited page and should be confirmed with Planning/Zoning.[2]
If a sign is creating an immediate safety hazard, contact the city's building or code enforcement office immediately.

Applications & Forms

Sign permits and required application materials are managed by the Building Division. The official sign permit form, submittal checklist, fees, and required drawings are provided on the city's permitting page; if a specific digital-sign application number appears in the code, it is not specified on the cited municipal code page and applicants should use the online sign-permit packet from the Building Division.[2]

  • Permit name: Sign Permit (use the Building Division's sign permit packet and checklist).
  • Fees: fee schedule published on the Building Division permit page; specific digital-sign fee amounts are listed on the city's permit page rather than in the municipal sign chapter.
  • Submission: electronic or in-person per Building Division instructions; see the city's sign permit link for current submission methods and acceptance hours.[2]

Compliance best practices

  • Install automatic dimming or ambient light sensors to reduce brightness at night.
  • Limit rotation/animation speed and transitions to avoid rapid flashing that can distract drivers.
  • Keep documentation of permitted brightness settings and manufacturer specifications to show inspectors.
Maintain documentation of approved permit conditions on site for inspections.
