What permits do you need to open a contractor or trade in Nampa?

There is no single figure, and any site quoting one is rounding away the part that matters. Of the 14 records listed for a contractor or trade in Nampa, ID, 2 apply to every business of this type and 12 are conditional. Adding every fee on the page together would overstate what most operators pay, because it would include permits they never need.

2 of the 14 are charged as a range or a formula set by the issuing agency, and 4 have no fee published at all. The ones that vary:

Commercial Building Permit & Certificate of Occupancy: Exhibit A valuation-based table: $22.20 for the first $500 of construction value, rising through tiered increments (e.g. $65.40 for the first $2,000 plus $13.23 per additional $1,000 through $25,000, up to $5,299.94 for the first $1,000,000 plus $3.45 per additional $1,000 above that). Plan review for all building occupancies is a further 65% of the building permit fee. Commercial sub-contractor (plumbing/mechanical/electrical) permits are priced separately at a $36.00 base fee plus a percentage of project valuation (2.68% up to $20,000, stepping down at higher tiers).

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

Permits for a contractor or trade in Nampa, ID come from 5 separate offices: City of Nampa, Office of the City Clerk, City of Nampa, Building Safety Department, City of Nampa, Planning & Zoning Department, Idaho Secretary of State, Business Services Division, Idaho Division of Occupational and Professional Licenses. No single office issues them all, which is why an opening means filing in several places rather than one.

No fee applies to a general Nampa business licence, because none exists. Two independent City FAQ pages confirm this in nearly identical language: 'the City of Nampa does not have a city-wide business license,' and '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 own complete licence list confirms this — none of its enumerated categories reaches 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.

A genuine, confirmed valuation-based fee table read directly from the City's own current Exhibit A schedule. Unlike this project's Boise ($175 flat) and Meridian ($110 flat) files, this project could not find a standalone flat dollar figure for a Certificate of Occupancy Only application anywhere in the City's own published materials — the City's own Certificate of Occupancy Only Permit Application and Building Permit Process page both describe the process and the Occupancy-versus-Completion distinction, but neither states a flat fee, so a change-of-tenant Certificate of Occupancy appears to be priced through this same valuation table at whatever value the reviewed scope of work carries.

No fee applies to a standalone Zoning Verification Letter, because the City's own current Planning & Zoning Fee Schedule does not publish one. The Department's own services page advertises Zoning Verification Letters as an available product with a request form, but unlike the Conditional Use Permit ($350) and Temporary Use Permit ($50/$75) priced on the same document, this project could not find a dollar figure for this specific letter anywhere in the current published schedule.

Applies only to a business operated out of a home, not a commercial storefront — most relevant here to a home-based personal trainer or fitness instructor, a home-based hairstylist or nail technician, or a contractor running an office (not a yard or shop) from home. This project could not find the exact chapter/section number for Nampa's Home Occupation zoning provisions, unlike the Massage Establishment License, Temporary Use Permit, Sign Permit, and Conditional Use Permit recorded elsewhere in this file, each of which cites a specific code chapter or section directly.

No fee applies beyond Idaho's own state Contractor Registration fee, recorded at the state layer. This project found no Nampa-published page describing a general contractor-verification practice the way Boise's own Planning & Development Services FAQ page does, but did find the state credential surfaced directly on a City application: the Planning & Zoning Department's own Sign Permit checklist requires the applicant to state 'my Contractors Registration Number issued by the State of Idaho as required by Chapter 52, Title 54 of the Idaho State Code' or claim an exemption under Idaho Code 54-5205 — confirming the same state-registration-verification-at-permit-time pattern this project's Boise and Meridian files already recorded, through a different specific application rather than a general FAQ statement.

A genuine, confirmed impact fee schedule with the City's own explicit occupancy-to-category mapping table — cleaner than this project's Boise file, which left that mapping as a disclosed gap, and comparable to Meridian's own explicit 'Commercial'/'All Other' split. Auto repair is a genuine, complete gap in Nampa's own table: unlike Gas Stations, Convenience Stores, Motor Vehicle Showrooms, and Carwash (all mapped to Retail), no category anywhere 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 disclosed rather than resolved by assumption.

No fee, and Idaho's own small-business portal says so in as many words: Idaho does not have a state business licence, and registering an entity with the Secretary of State is a registration rather than a licence. City-level licensing varies widely, and many Idaho cities require none at all.

A hundred dollars online against $120 on paper — the paper fee is really the online base plus a $20 manual-processing surcharge, and a paper form must additionally be typed rather than handwritten. A corporation costs the identical amount either way.

The same $100 online, $120 on paper as an LLC. Expedited service adds $40 on top of either channel, and same-day service adds $100.

Filing this online costs nothing at all; the only version that carries a fee is a paper filing accepted in person at the Boise office, priced at the same $20 manual-processing charge that applies across the Secretary of State's other paper filings. The due date tracks each entity's own formation anniversary rather than one shared calendar date. Missing it triggers a notice of intent to dissolve, and the entity then has sixty days to cure before administrative dissolution follows; reinstatement remains possible for up to ten years after that.

This is registration, not a competency licence — the governing act itself is explicit that it requires registration rather than licensure, and no examination sits behind it. Any construction job over $2,000 in combined materials and labour triggers the requirement unless the contractor is otherwise exempt. A fee change effective 1 July 2026 raised the registration to $120 and introduced a biennial option at the same $120 for two years or $60 annually; the board's own FAQ page has not yet been updated to match and still describes annual renewal tied to the registrant's birthday, so confirm the current cycle directly with the board before relying on either description.

The two tiers here run on entirely different clocks — an electrical contractor licence renews every year at $100, while a master electrician's licence, at $65 plus the same $15 application, runs for three years before renewal. Plumbing and HVAC follow the master electrician's three-year pattern rather than the contractor's annual one.

Plumbing is the most expensive of Idaho's three licensed trades to enter, at roughly $244.50 in total once the application, examination and initial licence fees are added together, though renewal every three years is a comparatively modest $108. Reinstating a lapsed licence costs the full $147 licence fee again.

Two hundred and sixty dollars to open, on the same three-year cycle as plumbing and master electrician licensing, with renewal at $150 and reinstatement at the full $225 licence fee.
