How much does it actually cost to permit a contractor or trade in Canyon County?
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 Canyon County, ID, 0 apply to every business of this type and 14 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 1 has no fee published at all.
The other 2 variable fees belong to permits that apply to every type of business here; their formulas are set out on the Canyon County permits page and the ID state page.
Which offices issue these permits in Canyon County?
Permits for a contractor or trade in Canyon County, ID come from 4 separate offices: Canyon County Development Services Department, Southwest District Health, Idaho Secretary of State, Business Services Division, Idaho Division of Occupational and Professional Licenses.

What does a contractor or trade need in Canyon County that other businesses do not?
4 of the 5 permits particular to a contractor or trade here apply to no other business type we cover in Canyon County: Electrical Contractor or Master Electrician License, Plumbing Contractor License, HVAC Contractor License and Contractor Registration.
Electrical Contractor or Master Electrician License
The two tiers here run on entirely different clocks — an electrical contractor license renews every year at $100, while a master electrician's license, 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 Contractor License
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 license fees are added together, though renewal every three years is a comparatively modest $108. Reinstating a lapsed license costs the full $147 license fee again.
HVAC Contractor License
Two hundred and sixty dollars to open — a $35 application plus a $225 license fee — on the same three-year cycle as plumbing and master electrician licensing, with renewal at $150 and reinstatement at the full $225 license fee.
Contractor Registration
This is registration, not a competency license — 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.
