Signs and Advertising Michigan 4 Minutes Read · published March 01, 2026 Flag of Michigan

Ann Arbor, Michigan regulates commercial and temporary advertising as well as historic signage through local code and historic‑preservation review. This guide summarizes how the city treats prohibited ads, when the Historic District Commission or planning staff may require removal or modifications, and what property owners and advertisers should do to comply, report violations, or appeal orders. It highlights enforcement pathways, typical violations, and practical steps to get permits, request a review, or report an unlawful sign to city staff.

Scope & When Rules Apply

Local sign rules apply to signs on private property, public right-of-way obstructions, and signs in historic districts. Historic-designation review can apply to signs on properties in local historic districts or on landmarked buildings; those signs may need approval before alteration or removal. For the controlling municipal code and zoning provisions, consult the city code and zoning sign chapters for details [1].

Historic signs on landmarked properties often require review before any permanent change.

Common Prohibited Ads

  • Signs placed in the public right-of-way without permit, including stakes and banners that block sidewalks or sight lines.
  • Off-premises commercial advertising where off-site signs are restricted by zoning.
  • Signs that damage or alter historic fabric without approval from the Historic District Commission or planning staff [2].

Penalties & Enforcement

Enforcement is handled by the City of Ann Arbor departments responsible for code compliance, planning, and historic preservation. Where a specific code section sets a penalty, the citation appears in the municipal code or related enforcement page; if fine amounts or escalation rules are not shown on the cited page, this guide states that they are "not specified on the cited page" and points to the official source [1].

  • Fine amounts: not specified on the cited page; see the municipal code link for any enumerated fines or civil penalties [1].
  • Escalation: first, repeat, and continuing-offence procedures and incremental fines are not specified on the cited page when not listed in the code text; check the ordinance section for details [1].
  • Non-monetary sanctions: removal orders, stop-work or removal notices, seizure of signs blocking rights-of-way, and injunctive or court actions are available remedies under city enforcement.
  • Enforcer and inspection: City of Ann Arbor Code Compliance/Planning staff and Historic Preservation staff enforce sign regulations; complaints may be submitted online or to the relevant office [3].
  • Appeals and review: appeal routes typically go to the City’s administrative hearings or the Historic District Commission depending on the order; specific appeal time limits are not specified on the cited page and should be confirmed with the enforcing office [1].
  • Defences and discretion: permits, variances, or documented special approvals (for example, a certificate of appropriateness in a historic district) can provide lawful defenses; emergency removals for safety may be authorized by staff.
If you receive a removal order, act quickly to preserve appeal rights and meet any deadlines.

Applications & Forms

  • Sign permit or zoning compliance application: check City of Ann Arbor Planning & Development for the current sign permit form and submission instructions; if no form is published online, contact planning staff [1].
  • Historic district certificate of appropriateness: application materials and fees are managed by the Historic Preservation/Planning office; consult the historic resources page for forms and schedules [2].

Action Steps: Remove or Report an Illegal or Unsafe Sign

  • Document: photograph the sign, note location, measurements, and any damage to property or obstruction of public way.
  • Report: file a complaint with City of Ann Arbor code compliance or use the city report-a-problem portal to request inspection [3].
  • Apply: if the sign may be made lawful by permit, submit the sign permit or historic approval application to Planning & Development or Historic Preservation staff.
  • Pay or appeal: if fined or ordered removed, follow the notice for payment and appeal deadlines; seek clarifying documentation from the enforcing office.
