Business licenses and permits in Nampa, Idaho

The City of Nampa's FAQ pages state that 'the City of Nampa does not have a city-wide business license' and that 'The City of Nampa does not issue general business licenses. Licenses are only required for specific types of businesses'; the City Clerk's Licenses page lists Alcohol Catering, Amusement, Animal/Dog, Beer/Wine/Liquor, Concessions, Massage Establishment, Motor Escort, Pawnbroker, Peddler/Solicitor, Private Security/PI/Alarm, Special Event, Tree Removal/Pruner and Used Precious Metal/Jewelry/Gem Dealer licenses and permits. Food trucks route through the generic Peddler/Solicitor License ($25/3mo, $50/6mo, $100/yr, plus a $42 background fee every other year) and a Planning & Zoning Temporary Use Permit ($50/1mo, $75/6mo) rather than a dedicated mobile-vendor license. Southwest District Health, which serves Canyon County and five neighbouring counties, is the food-permitting authority, with its own published fees of $200-$250 for a permanent establishment and $80-$100 for a mobile unit. Fire service is provided by the independent Nampa Fire Protection District, not a City department; its published fee schedule prices a $45 Mobile Food Truck Permit, a $175-per-unit Cooking Hood Extinguishing System Permit, sprinkler/alarm permits, a $120/$85 Places of Assembly fee, a $25 Day Care Inspection and a $200 Residential Access & Water Supply Permit for in-home daycare, and that schedule shows no repair-garage or motor-fuel-dispensing permit line. Building permits use a valuation-based Exhibit A table with 65% commercial plan review; the Building Safety Department's Commercial FAQ states that fees are based on the value of the work, and no standalone flat Certificate-of-Occupancy fee is published. Sign permits are processed under that same table. A Conditional Use Permit is $350; Home Occupation and Home Occupation-Daycare accessory permits are each $100; no fee is published for a standalone Zoning Verification Letter. The City licenses massage establishments ($100 + $42 background), which covers massage services specifically rather than salons generally. The City's 2026 non-residential impact fee schedule maps Restaurants/Coffee Shops/Retail Stores/Barber & Beauty Shops to 'Retail,' Child Daycare and Animal Hospitals/Kennels to 'Institutional,' and Professional Services to 'Office,' and that table names no auto repair category. The City Clerk's Licenses page names no veterinary or contractor license; Idaho's state contractor registration number is required on certain City permit applications.

Non-Residential Development Impact Fees (Parks, Police, Fire, Streets)City of Nampa, Building Safety DepartmentEffective for building permits submitted on or after January 1, 2026 ('with no exceptions,' per the City's own bulletin), priced per 1,000 square feet of new non-residential floor area, with no Parks impact fee on non-residential construction. The City's own Impact Fee Category by Occupancy table places 'Restaurants/Fast Food Restaurants/Deli's/Coffee Shops,' 'Retail Stores,' and 'Barber and Beauty Shops' under 'Retail' (Police $1,758 + Fire $2,311 + Streets $9,922 = $13,991 total per 1,000 sq ft). It places 'Child Daycare Facilities' and 'Animal Hospitals, Kennels, Shelters/Pounds' under 'Institutional' (Police $674 + Fire $885 + Streets $3,804 = $5,363 total). It places 'Professional Services (Architects, Attorneys, Accountants, Insurance, Locksmith, etc.)' under 'Office' (Police $678 + Fire $891 + Streets $3,804 = $5,373 total) — the closest documented analogue for a contractor's office, though the table does not name 'contractor' directly. Gymnasiums appear only as '(High density over 600 occupants)' and '(Low density over 600 occupants),' both mapped to Retail, leaving a small fitness studio under that threshold without an explicit category of its own.one-time, per project2026-09-11

What do these permits involve in Nampa?

Commercial Building Permit & Certificate of Occupancy

A valuation-based fee table read from the City's current Exhibit A schedule. Nampa publishes no standalone flat dollar figure for a Certificate of Occupancy Only application: the Building Safety Department's own Commercial FAQ states that 'Fees are based on the value of the work as outlined in the fee schedule adopted by City Council,' and the Certificate of Occupancy Only Permit Application and Building Permit Process page likewise describe the process and the Occupancy-versus-Completion distinction without stating a flat fee. A change-of-tenant Certificate of Occupancy is therefore priced through this same valuation table, at whatever value the reviewed scope of work carries.

Zoning Verification Letter (Nampa)

The Planning & Zoning Department's current online 'Request for Zoning Verification Letter' form states no fee anywhere on it, and the City's Planning & Zoning Fee Schedule lists no line for a standalone Zoning Verification Letter, unlike the Conditional Use Permit ($350) and Temporary Use Permit ($50/$75) priced on the same document. The form covers land-use confirmation only for properties and addresses located within the City of Nampa, and directs other property-information requests to a public records request.

Fire Sprinkler, Alarm & Commercial Kitchen Hood Suppression System Fees

The sprinkler/alarm permit fees and the 20% fire code plan review apply broadly to any commercial tenant improvement or new construction with fire protection systems, across the industries listed here. The $175-per-hood-unit Cooking Hood Extinguishing System Permit is the specific, real line item a restaurant, coffee shop, or food-truck commissary kitchen pays for its range-hood suppression system, confirmed directly from the Nampa Fire Protection District's own current fee schedule.

Sign Permit

Nampa processes a sign permit as a building permit under the same Exhibit A valuation table used for general construction, rather than pricing signs on a separate sign fee schedule; the fee therefore follows the declared value (time and material) of the sign. The Sign Permit Guide also requires the applicant to state an Idaho Contractor Registration Number under Idaho Code 54-5209, or claim an exemption under 54-5205.

Non-Residential Development Impact Fees (Parks, Police, Fire, Streets)

An impact fee schedule with the City's own explicit occupancy-to-category mapping table. The table does not cover auto repair: unlike Gas Stations, Convenience Stores, Motor Vehicle Showrooms, and Carwash (all mapped to Retail), no category on the table names an auto repair or vehicle repair use, so this industry is not included above and a business owner should confirm the applicable category directly with the Building Safety Department before budgeting for new construction. Fitness studios and contractors are included above, with the ambiguity in their exact category stated rather than resolved by assumption.

General Business License — City of Nampa Position

The City of Nampa's FAQ pages state that 'the City of Nampa does not have a city-wide business license' and that 'The City of Nampa does not issue general business licenses. Licenses are only required for specific types of businesses, including those that sell alcohol, door-to-door sales, pawnbrokers, alarm installers, private investigators, private security, motor escorts, and gem dealers.' The City Clerk's Licenses page lists only specific-activity licenses and permits (alcohol, amusement, animal, concessions, massage establishment, motor escort, pawnbroker, peddler/solicitor, private security/investigator/alarm, special event, tree removal/pruner and used precious metal/gem dealer). Per those FAQ pages, there is no city-wide business license fee for a plain restaurant, retail store, salon, fitness studio, veterinary clinic, contractor's office or auto repair shop that does not engage in one of those specific activities.
