Electrical Permit in Riverton, Wyoming

Required for electrical wiring installation, alteration, or repair in the City of Riverton. Per the Wyoming Dept. of Fire Prevention & Electrical Safety 'LOCAL AND STATE JURISDICTIONS' chart, Fremont County's ELEC columns are marked S/S (state) at the COUNTY level — but Riverton's own Municipal Code shows the CITY itself independently adopted the National Electrical Code by dynamic reference to 'the latest edition' (RMC § 15.08.110(B)(2); Chapter 15.08 'Electrical Code') — currently the 2026 NEC, effective statewide July 1, 2026 per wsfm.wyo.gov/electrical-safety (the 2023 NEC applied from July 1, 2023 until then) — and operates its own electrical permitting and inspection program under a city Electrical Inspector, distinct from the unincorporated-county default. The State of Wyoming (WSFM) continues to license individual electrical contractors/journeymen statewide, but inside Riverton city limits it is the CITY that issues the wiring permit and performs rough/final inspections.

Tips

  • IMPORTANT determination: the WY State Fire Marshal jurisdictions chart marks Fremont County's electrical columns as state (S/S) at the unincorporated-county level, and the framework's default assumption for Riverton going in was 'state program.' However, Riverton's OWN Municipal Code (Chapter 15.08, 'Electrical Code,' adopted under W.S. § 35-9-121(a)(iv) delegated authority) shows the city runs its own electrical permitting and inspection program inside city limits, with its own Electrical Inspector empowered to permit, inspect, and disconnect service for code violations. This is grounded directly in RMC §§ 15.08.010–15.08.100, cross-checked against the city's own 'Local Design Criteria' page which states 'We have adopted the 2023 National Electrical Code Effective July 1st, 2023' — a page not reworded since (re-verified live 2026-07-17, text unchanged); however the OPERATIVE ordinance text at RMC § 15.08.110(B)(2) requires conformity with 'the latest edition of the National Electrical Code,' a dynamic (ambulatory) reference rather than a fixed 2023 citation — meaning Riverton's applicable edition today is the 2026 NEC, effective statewide July 1, 2026 per wsfm.wyo.gov/electrical-safety, the same as the state default — and the city's own Inspection Procedures list, which includes 'Temporary Electric Service' and 'Rough Electric' as city-performed inspections in the standard permit sequence. Confirm with the Building Department at (307) 856-2999 if your parcel is inside Riverton city limits vs. unincorporated Fremont County — the county (outside city limits) follows the WSFM state program (see the Wyoming State Fire Marshal Wiring Permits page).
  • The State of Wyoming still LICENSES electrical contractors, journeymen, and apprentices (WSFM Dept. of Fire Prevention & Electrical Safety, Chief Electrical Inspector) — this licensing role continues regardless of who inspects the work; Riverton additionally requires contractor registration with the city. Contractor
  • A homeowner may pull their own electrical permit and perform the work with their own hands in their own owner-occupied one-family dwelling (RMC § 15.08.080.A.2) — but the electrical inspector will not issue the permit unless the person performing the work is specifically named on it. Owner-builder
  • There is no separate flat electrical permit fee schedule; electrical work is charged under the general alterations category of Resolution No. 1355 (Electrical Service Upgrade $52 min, Electrical Alteration $26 min) or bundled into the new-construction per-square-foot fee if part of new construction.

The 2026 National Electrical Code (NFPA 70), effective statewide July 1, 2026. Riverton Municipal Code § 15.08.110(B)(2) (Chapter 15.08 'Electrical Code') requires conformity with 'the latest edition of the National Electrical Code' — a dynamic reference that tracks the state's current edition, per wsfm.wyo.gov/electrical-safety. The 2023 NEC was the applicable edition from July 1, 2023 until the 2026 edition took effect. Note: the City's own 'Local Design Criteria' webpage still displays outdated text stating 'We have adopted the 2023 National Electrical Code Effective July 1st, 2023' (re-verified live 2026-07-17) — the ordinance's ambulatory 'latest edition' language controls regardless of that page's wording.

Inside Riverton city limits, the City itself issues electrical wiring permits and performs inspections, under its own Electrical Code (Riverton Municipal Code Chapter 15.08) and its own Electrical Inspector position — this is separate from the Wyoming State Fire Marshal's default statewide program that covers jurisdictions without delegated electrical authority (such as unincorporated Fremont County). The State continues to license individual electrical contractors and journeymen. Confirm with the Community Development Department at (307) 856-2999 if you are unsure whether your project address is inside city limits.

Yes. Riverton Municipal Code § 15.08.080(A)(2) allows a homeowner to obtain an electrical permit to perform work with their own hands in their own owner-occupied one-family dwelling, provided the person performing the work is named on or countersigns the permit.
