  1. 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

  2. Nampa Stormwater Discharge Prohibition (Illicit Discharge)

    Pressure washing businesses in Nampa must not let wash water containing detergents, chemicals, or contaminants reach storm drains, gutters, or waterways — this is prohibited under the city's illicit-discharge/MS4 stormwater program run by Public Works Environmental Resources. Capture and contain wash water and dispose of it through an approved sanitary sewer connection. Nampa's stormwater permits cover construction-site erosion control, not service businesses like pressure washing, so there is nothing to apply for; violations are subject to enforcement.
