Contractor licensing

Idaho contractor license requirements

Idaho does not issue a general contractor license. It requires registration with the Idaho Contractors Board for anyone doing a construction job worth more than $2,000, with proof of liability and workers' compensation coverage.

Idaho has no general contractor license and no trade exam for builders. What it has is mandatory registration. Under the Idaho Contractor Registration Act, any person who takes on a construction job worth more than $2,000 in materials and labor, and is not exempt, must register with the Idaho Contractors Board, which sits inside the Division of Occupational and Professional Licenses (DOPL). Registration means paperwork, a fee, and proof of insurance, not a test. Electricians, plumbers, HVAC installers, and contractors bidding public works are handled by separate DOPL boards.

Who has to register, and who is exempt

The trigger is the size of the job, not the size of the company. A deck builder who takes a $2,400 job needs a registration. A handyman doing $1,500 jobs does not, as long as each job stays under the line. Count both labor and materials when you price it, because the board does.

The board's FAQ lists these exemptions:

  • Other licenses: licensed electrical contractors, plumbers, HVAC installers, architects, engineers, surveyors, manufactured home installers, and similar licensees do not register unless they contract beyond the scope of their license.
  • Public works licensees: contractors and construction managers licensed for public works may register for private work outside that license and are exempt from paying the fee.
  • Employees paid wages by a contractor.
  • Suppliers who do not install or fabricate the materials.
  • Owners doing their own work on their own land who do not plan to sell within 12 months.
  • Commercial building owners maintaining their own buildings with their own crews.

How to register as a contractor in Idaho

  1. Create an account on DOPL's Online Services portal and start the Contractors Board application.
  2. Provide your Social Security number (individual) or employer tax ID (business), the name and address you do business under, and the name and address of every owner, partner, member, or shareholder.
  3. Upload a certificate from an insurer authorized in Idaho showing general liability coverage, including products and completed operations, of not less than $300,000 single limit.
  4. Upload proof of workers' compensation coverage, or a statement explaining why coverage is not required for you.
  5. Describe the type of construction you will do, and disclose any contractor license or registration that was ever denied or revoked in any state.
  6. Pay the $120 application fee. The five-member board (four contractors and one public member) approves applications.

Insurance is where most applications stall. Ask your agent for a certificate of insurance that names the completed operations coverage, not just a declarations page, and make sure the limit reads at least $300,000. If you hire subs, collect the same proof from them, because Idaho puts that duty on you.

Fees and the switch to 2-year renewals

DOPL's fee table effective July 1, 2026 lists $120 for an initial individual or business registration, $60 for an annual renewal, and $120 for a biennial renewal, plus a $40 reinstatement fee if you let it lapse. DOPL began moving contractor registrations from one-year to two-year terms on October 14, 2025. Registrants born in odd years moved first; those born in even years move to the two-year cycle starting in 2026. Once you renew on the two-year cycle, the fee doubles to cover both years. You can renew up to 60 days before your expiration date.

What registration requires after you have it

  • Show your number. Within 60 days of registering, display your registration number at your place of business and jobsite, and on advertising, contracts, building permits, letterheads, purchase orders, and subcontracts.
  • Check your subs. You must get satisfactory proof that everyone you engage on the job is registered. Hiring an unregistered sub violates the Act and can cost you lien rights.
  • Keep insurance current. Failing to keep liability or workers' compensation coverage is grounds for revocation.

Residential disclosure rules

Idaho adds two disclosure duties for general contractors on homes. Under Idaho Code Section 45-525(2), before signing a contract over $2,000 with a homeowner or buyer of residential property, you must give a disclosure statement and keep a signed receipt. It tells the owner they can require lien waivers from subs, ask for proof of liability and workers' compensation coverage, buy an extended title policy covering unrecorded liens, and require a surety bond at their own expense.

Before final payment (or before closing on new construction), a second signed disclosure must list the name, address, and phone number of every sub, supplier, and equipment rental company with a direct contract with you that furnished more than $500 of work or materials. Skipping either disclosure counts as an unfair or deceptive practice under the Idaho Consumer Protection Act, and the board can discipline you for it.

Public works and trade licenses

Public jobs run on a different license. DOPL's Public Works Contractors License Board issues class-based licenses so that contractors on public construction have the money and know-how to perform. Initial fees in effect since January 1, 2025 run from $160 for Class C up to $880 for Unlimited, with AAA, AA, A, B, and CC in between and $320 for a Construction Manager license. DOPL also began a fee holiday for this board on January 1, 2026, so confirm what you will actually pay on the board's news page. The board began moving to two-year licenses on April 1, 2026. If you plan to bid city, county, or school work, start there, and read Idaho prevailing wage rules before you price it. Electrical, plumbing, and HVAC work each have their own DOPL boards and licenses.

Idaho contractor license lookup

To check a registration, use the public search on DOPL Online Services (edopl.idaho.gov). Search by name or registration number and confirm the status is active before you sign a subcontract or cut a check. Questions go to DOPL at (208) 334-3233. Smart Business Automator stores each sub's registration number and insurance expiration so you can see who is current before they mobilize; see subcontractor compliance automation.
