Signs and Advertising Michigan 4 Minutes Read ยท published February 07, 2026 Flag of Michigan

In Detroit, Michigan, businesses and property owners who place A-frame or sandwich board signs on sidewalks must follow municipal rules that protect pedestrian safety, ADA access, and the public right-of-way. This guidance explains where signs may be placed, permit and right-of-way considerations, enforcement pathways, and practical steps to reduce risk of fines or removal. Where the city code or department pages do not state a specific figure or deadline, this article indicates that the detail is "not specified on the cited page" and directs you to the enforcing department for up-to-date requirements.

Keep at least the minimum clear path for pedestrians and wheelchair users.

Where A-frame and Sandwich Board Signs Are Allowed

Placement rules generally require that signs not obstruct pedestrian travel, emergency access, or building egress. The City of Detroit municipal code and department guidance address signs and obstructions in the public right-of-way; consult the municipal code for regulatory language[1].

  • Maintain unobstructed pedestrian clearance on sidewalks; the exact minimum clearance is not specified on the cited page[1].
  • Do not place signs that block curb ramps, bus stops, or bike lanes; these restrictions are enforced by city departments overseeing right-of-way use[3].
  • A-frame signs must not create tripping hazards or sight-line obstructions at intersections.

Permits, Approvals, and Right-of-Way Use

Some uses of the public right-of-way require a permit. Sign permits and building/structural approvals are processed through the Building, Safety Engineering and Environmental Department (BSEED) or the department that handles sign permitting[2]. Right-of-way use or obstruction permits may be required from Public Works for any permanent or recurring placement in the public sidewalk area[3].

  • Apply for a sign or right-of-way permit when placement encroaches on the public right-of-way or when the department requires formal approval[2].
  • Fees for permits are handled by the permitting department; specific fees are not specified on the cited department pages[2].
  • Permit processing times and renewal terms are set by the issuing office and are not specified on the cited pages[2].
If in doubt, request written guidance from the permitting office before placing a sign.

Penalties & Enforcement

Enforcement may be carried out by city code enforcement officers, BSEED inspectors, Public Works, or other designated municipal officers. The municipal code contains provisions addressing signs, sidewalk obstructions, and enforcement remedies; fine amounts and escalation details are not specified on the cited municipal code page and should be confirmed with the department[1].

  • Monetary fines: not specified on the cited page; verify amounts with the enforcement office[1].
  • Non-monetary sanctions: orders to remove signs, seizure of obstructing items, and abatement actions are described or implied in enforcement provisions; specifics are not specified on the cited page[1].
  • Escalation and repeat offences: not specified on the cited page; some notices typically include timeframes to cure before further action.
  • Inspection and complaint pathways: report sidewalk obstructions or sign violations to the appropriate department or 311; Public Works and BSEED oversee public right-of-way and building/sign compliance[2][3].
  • Appeals/review: appeal routes and time limits are handled per municipal procedures and are not specified on the cited pages; contact the issuing department for appeal instructions and deadlines.

Applications & Forms

To determine required forms: check the Building, Safety Engineering and Environmental Department permit pages for sign permit applications and the Public Works permit pages for right-of-way use forms. If no form is required or none is officially published, that will be indicated by the department pages[2][3].

Common Violations

  • Blocking required pedestrian clearance or ADA routes.
  • Placing signs in travel lanes, bus stops, or bike lanes.
  • Failing to obtain permits when right-of-way use is regulated.
Unauthorized signs in the public right-of-way may be removed without prior notice.

Action Steps

  • Contact BSEED or the Public Works permit office to confirm whether a permit is required before placing a recurring sign[2][3].
  • If cited, follow removal orders and pursue appeal instructions from the issuing department promptly.
