  1. Idaho DOPL Electrical Board — Electrical Contractor License

    Electrical contractors in Idaho hold a State Electrical Contractor License from the Electrical Board at the Division of Occupational and Professional Licenses (DOPL). DOPL absorbed the former Division of Building Safety, and the old dbs.idaho.gov address now redirects away. The licence requires a qualifying master or journeyman electrician associated with the business, and the exam-based licence path applies to the individual qualifier. The contractor licence runs one year.

    Official government source

    $140 to start: $15 application fee plus $125 contractor licence fee. Renewal is $100/year; reinstatement is $125. Individual licences are separate — journeyman $55 (3 years), master $65 (3 years).4–8 weeks, longer if the qualifying individual still needs to sit the exam.

  2. No Nampa General Business License

    Nampa does not issue a general business license. The City Clerk licenses only specific regulated categories: alcohol and alcohol catering, amusement operators, animal/dog licences, concessions, massage establishments, motor escort services, pawnbrokers, peddlers and solicitors, private security/private investigators/alarm installers, special events, tree removal and pruning, and used precious-metal and jewelry dealers. Businesses outside those categories — contractors, salons, tutoring, real estate, insurance, notaries, pet services, auto repair, photography, cleaning, and the like — need no city business license. Zoning approval, a Certificate of Occupancy, and an In-Home Business registration for home-based operations may still apply.

    $0 — no general business license exists. Category-specific fees apply only to the licences listed above.N/A for most businesses — nothing to apply for

  3. City of Nampa Electrical Permit (per project)

    An electrical permit must be pulled from the City of Nampa Building Safety & Code Division for each project inside city limits — Canyon County does not permit work in Nampa. Residential permits are priced from a flat 'electrical extras' list; commercial permits use a base fee plus a percentage of the scope-of-work valuation. A final inspection is required, and starting work without a permit doubles the fee.

    Official government source

    $36 base permit fee, plus either residential extras ($55 main/sub-main service, $55 temporary service, $15 per circuit extension, $15 miscellaneous equipment) or, for commercial work, 2.68% of project value up to $20,000 with lower marginal rates above that. Re-inspections after the first are $55.1–5 business days for straightforward permits; longer where plan review is required.
