Fee schedule

Electrical Permit (residential)Chapter 4 Section 1.8.E 'All Other Permits: No fees.' — Campbell County charges no fee for residential electrical permits, unlike the WSFM's statewide $50 electrical permit fee that applies where the state program has jurisdiction. This fee-free treatment applies because Campbell County has delegated BOTH building and electrical authority and elected not to charge for residential trade permits.

Tips

  • Unlike most Wyoming jurisdictions where electrical defaults to the state's Chief Electrical Inspector program (WSFM, $50 base fee), Campbell County runs its OWN electrical inspection program at no charge to the applicant — confirm this distinction before quoting the state's $50/tiered fee schedule for any Campbell County unincorporated project.
  • Electrical permits are required even for structures that are exempt from a Building Permit (rural dwellings outside platted subdivisions, exempt accessory structures, farm/ranch buildings, HUD manufactured homes).
  • Campbell County adopted the 2026 Edition of NFPA 70 (NEC) via its own Chapter 4 Section 10 (Amended June 2026) — independent of, and enacted before, the Wyoming State Fire Marshal's own statewide default program moving to the 2026 NEC effective 2026-07-01; Campbell County's local adoption governs here regardless of the state's default edition because electrical is enforced locally (WSFM chart: ELEC INSP/PR = L/L).
  • 2026-07-17 re-verification: live primary-source PDF (campbellcountywy.gov/DocumentCenter/View/211, header "Amended June 2026") Section 10.A still reads "The National Electrical Code, NFPA 70, 2026 Edition, including Informative Annex H... is adopted by reference" — confirming the 2026 Edition citation in this file is accurate and current.
