Electrical Permit
VerifiedRequired for electrical wiring, installations, and alterations in Green River. Governed by the National Electrical Code (NEC), latest edition as adopted by the Wyoming State Fire Marshal's Office (the 2026 NEC took effect statewide July 1, 2026 per wsfm.wyo.gov/electrical-safety; the 2023 NEC was in effect before that date), adopted locally by Code of Ordinances Sec. 7-76. IMPORTANT: unlike the WSFM 'LOCAL AND STATE JURISDICTIONS' chart's general S/S (state-enforced) classification for Green River, the city's OWN ordinance and forms show Green River enforces its electrical code locally under Home Rule — see localAmendments for the full discrepancy note.
Verified 2026-07-01 · Source

Solar PV Permit
VerifiedRooftop or ground-mounted solar photovoltaic installations in Green River require a building permit (structural) and an electrical permit, since solar PV falls under both the adopted 2024 IRC/IBC (structural/racking) and the locally-enforced NEC (electrical interconnection, Article 690).
Verified 2026-07-01 · Source
Requirements
- Solar PV installation is not called out as a distinct permit type on the city's Work Requiring a Building Permit list or Building Permit Application form; it is processed as an Alteration/Addition building permit plus an Electrical Permit, per the general Sec. 105.1 requirement that any work regulated by the adopted codes (including electrical) requires a permit
- Structural plans showing roof-mount racking attachment and load path required for the building permit component
- Electrical single-line diagram, load calculations, and disconnect location required for the electrical permit component, per Sec. 7-76 (NEC adoption) and the Wyoming-licensed electrical contractor requirement
- Confirm with Development Services (307) 872-6140 whether your project needs the State Fire Marshal's office review in addition to City review

| Solar PV — Electrical Permit component | Charged under the same general valuation-based fee table (no distinct flat electrical line item published) | Consistent with how Green River charges all electrical work — see the electrical-permit entry. |
EV Charger / Electric Vehicle Charging Station Permit
VerifiedInstalling an EV charger circuit in Green River is electrical work regulated by the locally-enforced National Electrical Code (2026 NEC effective statewide July 1, 2026, per the Wyoming State Fire Marshal's Office; 2023 NEC applied previously). Green River has no distinct EV-charger permit type, application, or flat fee -- an EV charger circuit requires a standard City Electrical Permit, charged under the same general valuation-based Development Services fee schedule used for all electrical work (residential at 50% of the table, commercial/multi-family at 100%), the identical mechanism already documented in this corpus's electrical-permit and solar-pv-permit entries for Green River.
Verified 2026-07-20 · Source
Requirements
- Electrical Permit Application (checkbox on the City's Building Permit Application, DocumentCenter Doc #5572) required for a new dedicated EV charger circuit, per Sec. 7-76 (NEC adoption) and the Wyoming-licensed electrical contractor requirement
- Work must be performed by a Wyoming-licensed electrical contractor (or under a homeowner exemption where applicable), per City of Green River electrical permitting requirements
- No distinct EV-charger checklist or valuation-based line item is published; the general valuation-based Development Services Fees schedule (effective July 1, 2018) applies
- If the installation requires a new/upgraded electrical service to support the charger load, that scope is included in the same electrical permit valuation, not billed separately
- Confirm with Development Services (307) 872-6140 whether the specific installation needs additional review

Accessory Dwelling Unit (ADU) Permit
VerifiedGreen River's zoning ordinance (Code of Ordinances Appendix B, Chapter 9 — Use Regulations) has NO dedicated Accessory Dwelling Unit (ADU) permit type or zoning category. The zoning code's own definition of 'Accessory Buildings, Structures and Uses' (Section 9.6) explicitly excludes residential occupancy: an accessory use 'Does not include residential occupancy.' A second dwelling unit on a lot must instead be built as a recognized 'Multi-Unit Dwelling' use (permitted only in specific multi-family zoning districts, e.g. R-3/R-4), not as an accessory structure to a single-family home.
Verified 2026-07-01 · Source
Requirements
- No ADU-specific permit or zoning pathway exists in Green River; do not apply expecting an 'ADU' permit type
- An accessory structure (garage, shed, workshop) may NOT include residential occupancy per Zoning Code Section 9.6.A ('Accessory Buildings, Structures and Uses') and the Shed & Accessory Structure Brochure
- A genuine second dwelling unit on a property requires the lot to be zoned for Multi-Unit Dwelling use (the zoning Table of Uses permits 'Multi-Unit Dwelling' only in specific districts, e.g. R-3/R-4, not R-1/R-2 single-family districts) — this is processed as a standard residential building permit for a duplex/multi-family structure, not an ADU permit
- Confirm zoning district and permitted use eligibility with Development Services/Planning before attempting any second-unit project

Commercial Tenant Improvement Permit
VerifiedRequired for interior remodels, additions, and tenant improvements to commercial and industrial buildings in Green River. Governed by the 2024 International Building Code (IBC) as adopted by Sec. 7-16, charged at 100% (not the 50% residential rate) of the general valuation fee table.

Sign Permit (Special Use Permit for Electronic/Changeable-Message Signs)
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).
Reviewed 2026-07-22 · Source
Requirements
- 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 file -- 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

Fire Sprinkler & Fire Alarm System Permit (Wyoming State Fire Marshal's Office)
Installation, addition, or alteration of fire protection systems (fire sprinkler, fire alarm, and fire suppression systems) affecting Green River is regulated statewide by the Wyoming State Fire Marshal's Office (WSFM), Department of Fire Prevention and Electrical Safety, under Wyoming Statute Sec. 35-9-108 -- plan review and permitting is required 'regardless of size or valuation.' No evidence was found that the City of Green River or the Green River Fire Department separately issues its own local fire-sprinkler or fire-alarm permit: the City's own Building Permit Application (DocumentCenter Doc #5572) covers only Building/Electrical/Plumbing/Mechanical/Gas trades, this file's codesAdopted list of Chapter 7 building-code adoptions includes no locally-adopted Fire Code chapter, and the Green River Fire Department's own Fire Prevention page makes no mention of plan review, permitting, or fee authority. This differs from Green River's Home Rule electrical-permit arrangement (see electrical-permit entry) -- for fire protection systems specifically, WSFM plan review/permitting is the operative route found by this research.
Reviewed 2026-07-22 · Source
Requirements
- Plans and specifications for any new, added, or altered fire sprinkler, fire alarm, or fire suppression system must be submitted to the Wyoming Department of Fire Prevention and Electrical Safety (WSFM) for review and approval before work commences, per Wyoming Statute Sec. 35-9-108 -- required regardless of project size or valuation
- Submittals must include the appropriate WSFM Fire Sprinkler Plan Checklist or Fire Alarm Plan Checklist as applicable
- Plans are accepted or rejected for review within 5 business days of receipt; complete submittals receive full review within 21 business days of acceptance (extended by 10 business days, or to the original 21-day window if longer, when additional information is requested)
- Plan review fee must be paid before the Permit to Construct is issued
- Submitted and tracked through the Wyoming State Fire Marshal's Office eLicensing/ePermit/ePayment portal

Change of Use / Change of Occupancy Permit
VerifiedGreen River does not publish a standalone 'Certificate of Occupancy' application separate from its general Building Permit process. A change in the use or occupancy of an existing building or structure is expressly regulated as permit-triggering work under Section 105.1 of the adopted International Building Code (2024 IBC, per Sec. 7-16): any owner or authorized agent who intends to '...change the occupancy of a building or structure...' must first apply to the Building Official and obtain the required permit. The City's own Building Permit FAQ separately confirms that those intending to '...change the occupancy of a building' must call Development Services to schedule required inspections, and the Business Services page notes the Building Department may contact a business owner if a new business represents 'a change in occupancy use of the structure.' The Zoning Permit process (Development Services FAQ) also lists 'change in use [of] a property' among the actions requiring Zoning Permit approval, meaning a genuine change of use in Green River is a joint Zoning + Building Permit event rather than a single dedicated 'CO' product.
Verified 2026-07-22 · Source
Requirements
- Change of occupancy is processed as a Building Permit application under Section 105.1 of the adopted IBC (Sec. 7-16) -- not as a separate 'Certificate of Occupancy' product
- A change in use of a property separately triggers Zoning Permit (Approval) requirements per Development Services' published FAQ list
- For a new business occupying an existing structure, the Business License application is routed to Planning & Zoning staff to confirm proper zoning, and to the Building Department, which may contact the owner if the new use represents a change in occupancy classification requiring inspection/permit
- Required inspections must be scheduled with Development Services a minimum of 24 hours in advance, (307) 872-6140
- Confirm with Development Services whether your specific change of use also requires Wyoming State Fire Marshal's Office review (see fire-sprinkler-alarm-permit entry and this file's localAmendments notes on commercial WSFM review) and/or a Commercial Tenant Improvement Permit if the space is being physically altered for the new use
