Tips

  • IMPORTANT: Casper issues its own electrical permits and runs its own electrical inspections (Temporary Power, Rough Electrical, Service, Final) — this differs from Wyoming jurisdictions that default to the WY State Fire Marshal's statewide electrical program under W.S. § 35-9-119.
  • Casper's Building Inspection Division staff runs its own electrical inspections (per the City's Inspection Information page), confirming delegated local electrical enforcement authority under W.S. § 35-9-121; the City's Building and Fire Code Resources staff listing (re-checked 2026-07-16) currently names a Chief Building Official, Deputy Building Official, and Building Inspector but no longer names a separate Electrical Inspector by title.
  • Confirm current licensing/registration requirements for electrical contractors with Casper's Contractor Licensing program before applying.
  • There is no separate published electrical-only fee table — electrical work valuation is priced off the same combined Building/Electrical/Plumbing/Mechanical table used for building permits.
