The state of Idaho doesn't license general contractors working on private sector residential or commercial projects. That's done at the local level. However the state does license plumbers, electricians, well drillers, fire protection sprinkler contractors, and public works contractors.

Electrician's Licenses
Electrical work in Idaho requires a license. Idaho issues these licenses: contractor, journeyman, master journeyman, and specialty. To apply for a license, contact:
| Division of Building Safety Electrical Bureau, Licensing Section 1090 E. Watertower St. Meridian, ID 83642 (208) 334-2183 Fax: (208) 855-2165 http://www2.state.id.us/dbs/electrical/index.html |
The licenses have different requirements. Let's look first at the contractor's license. To qualify for a contractor's license you need to have two years of work experience (2,000 hours per year) as a licensed journeyman electrician or employ such a person at your company. The Bureau will review your application and if you're eligible they'll send you information on the exam they require. Exams are given once a month in Boise, Coeur D'Alene and Pocatello.
Now let's look at the journeyman's and master journeyman's license. To qualify for a journeyman's license you need to have four years of work experience in the trade and four years of approved electrical apprenticeship class room instruction. For the master license you need four years experience as a journeyman. Then the process is the same as for the contractor's license.
Electrician's license fees: It will cost you $15 to file the
application for a contractor's license, $60 for the exam, and $125 to get the license.
It's good until July 1 of the year after you got it. It will cost you $15 to file an application for the
journeyman or master journeyman license and $60 for either exam. The master license costs $65.
The journeyman license costs $55. Either license is good until July 1
of the year after you got it.
Idaho also licenses these specialty electrical trades:
| Elevator, dumbwaiter, escalator, or moving walk | Refrigeration, heating and air conditioning |
| Signs | Limited energy |
| Manufacturing or assembling equipment | Irrigation sprinkler |
| Well driller and water pump installer |
You need two years of experience in the trade to qualify for the exam. The exam has 30 to 50 questions and lasts two to two and one-half hours depending on the trade.
Fees and duration for specialty licenses are the same as those for electrical contractor and journeyman respectively.
With all these licenses, if you can prove you have a valid license in a state with qualifications at least equal to Idaho's, and you have the work experience Idaho requires, you can get an Idaho license without taking an exam. You still need to pay the fees, though.
