Full Breakdown

Nampa adopts the 2017 National Electrical Code, as amended by the Idaho Electrical Board, under City Code § 4-4-1. Section 4-4-2 requires an electrical permit from the building department before any wiring installation, equipment change, or new wiring begins; the permit is what authorizes work to start. Installations must be done by a state-licensed journeyman electrician working for a licensed electrical contractor, per § 4-4-4, though homeowners occupying group R-3 or U-1 dwellings for at least 180 days after completion may do their own wiring, as can immediate family helping a relative unable to do the work themselves.

Violations & Fines

Work without a permit is unauthorized; the building official can direct Idaho Power to disconnect electrical service to non-compliant or dangerous wiring until it passes final inspection.
