Sign Permit (Special Use Permit for Electronic/Changeable-Message Signs) in Green River, Wyoming

Green River regulates signs under Code of Ordinances Appendix B (Zoning Ordinance), Chapter 10 -- Sign Regulations. Notably, signage does NOT appear on the City's own 'Work Requiring a Building Permit' list (DocumentCenter Doc #4166), meaning standard signage is administered through the Zoning Ordinance's own Chapter 10 process rather than the Building Inspection Division's standard Building Permit workflow used for construction trades. A confirmed real-world example on file: an electronic/changeable-message ('electronic rate') sign requires a Special Use Permit issued by City Council resolution on recommendation of the Planning and Zoning Commission (City Council Proceedings, April 6, 2010, Resolution R10-38).

When you need this permit

  • Sign installation and design are regulated under City of Green River Code of Ordinances, Appendix B (Zoning Ordinance), Chapter 10 -- Sign Regulations
  • Electronic / changeable-message signs require a Special Use Permit issued by City Council resolution following Planning and Zoning Commission review -- confirmed instance: Resolution R10-38 (April 6, 2010) approved an electronic rate sign for the Oak Tree Inn, 1170 W. Flaming Gorge Way, with the condition that it display room rates only
  • Green River's 'Work Requiring a Building Permit' list (DocumentCenter Doc #4166) does not include signage, indicating non-electronic signage is not processed through the standard Building Permit workflow used for construction, plumbing, mechanical, and electrical trades
  • Illuminated signs will separately need a standard City Electrical Permit for the wiring/connection under Sec. 7-76 -- see the electrical-permit entry in this record -- since all electrical work in Green River is regulated regardless of the structure it serves
  • Confirm your specific sign type, size, and zoning-district requirements with Development Services / Planning and Zoning at (307) 872-6140 before installation

    Tips

    • Green River's 'Work Requiring a Building Permit' list (Doc #4166) does not include signage, meaning standard sign installation is governed by the Zoning Ordinance's own Chapter 10 (Sign Regulations) process rather than the standard Building Permit workflow used for construction trades.
    • Illuminated or electronic signs will also need a standard City Electrical Permit for the wiring/connection (see the electrical-permit entry in this record) in addition to any zoning sign approval, since all electrical work in Green River is regulated under Sec. 7-76 regardless of the structure it serves.
    • The only confirmed real-world example on record is a City Council-approved Special Use Permit for an electronic rate sign (Oak Tree Inn, 1170 W. Flaming Gorge Way) restricting its display to room rates only -- Special Use Permits for signs can carry content/use conditions, not just size/placement conditions.

    Frequently asked questions

    Sign installation is regulated under the City's Zoning Ordinance (Appendix B, Chapter 10 -- Sign Regulations). Electronic or changeable-message signs specifically require a Special Use Permit approved by City Council following Planning and Zoning Commission review; standard signage is not listed among the scopes of work on the City's 'Work Requiring a Building Permit' list, so it is administered through the zoning sign-regulation process rather than the standard Building Permit route. Confirm your specific sign type's requirements with Development Services at (307) 872-6140 before installation.
