Tips

  • Caldwell uses the 2023 National Electrical Code — ensure all work meets NEC 2023 requirements.
  • EV charger installations (240V) require an electrical permit as a circuit extension ($34 base + $22.25 per circuit).
  • Call inspection line (208) 455-4605 by 7:00 AM for same-day inspection scheduling.
  • Fire and Planning & Zoning inspections must be scheduled through the Citizenserve online portal only.
  • 2026-07-16 re-verification note: the city's own Electrical Permit Application PDF (revised 6/30/2026, v6) currently prints $195.00 for the new one/two-family 2,000+ sq ft dwelling line — that is the pre-FY2026 rate. The correct, currently effective fee is $255.00 per the signed FY2026 Resolution No. 300-25 (effective 10/1/2025; verified against the 2025-current-vs-2026-proposed fee comparison table attached to the resolution, and against the separately published fee-chart PDF, both of which show $255.00). Treat the application form's $195.00 figure as a stale/uncorrected entry, not a new rate.
