Overview of Billboard Regulation

Billboards in Dearborn are regulated through the city zoning and sign permit process. Billboard locations, permitted zones, dimensional limits, and illumination controls are addressed in the city sign rules and permit requirements; detailed technical standards and variances are administered by the Planning Division and Building Inspection.

For official ordinance text and the consolidated municipal code, see the City of Dearborn code of ordinances. Official code[2]

Typical Setbacks and Location Controls

Dearborn applies zoning-based controls to where billboards may be placed. Key items to confirm with the Planning Division include:

  • Whether billboards are allowed in the specific zoning district and any overlay districts.
  • Setbacks from property lines, public rights-of-way, and intersections.
  • Separation distance from residential zones, schools, parks, or historic sites.
  • Height limits and structural clearance requirements.

Exact numeric setback distances and separation rules are specified in the city sign/zoning rules and any applicable permit conditions; see the municipal code and consult Planning for site-specific determinations. Code and sign rules[2]

Illumination Limits and Light Controls

Illuminated billboards are typically subject to photometric, glare, and hours-of-operation limits. Controls can include maximum brightness (nits or equivalent), shielding requirements, and restrictions on animation or flashing illumination.

  • Limits on brightness and required shielding to avoid glare to drivers and neighboring properties.
  • Prohibited flashing, intermittent, or animated illumination unless expressly permitted.
  • Possible restricted hours for illumination in sensitive areas.

The municipal code or technical sign standards list the definitive illumination criteria; if numeric brightness levels or exact hour restrictions are needed, contact the Planning Division or Building Inspection for the controlling standard or permit condition. Official code[2]
