Idaho General Contractor License Requirements (2026)

Idaho runs two parallel systems for general contractors under the Division of Occupational and Professional Licenses (DOPL). Any person or firm bidding or performing a public works project with a total cost exceeding $50,000 must hold a Public Works Contractor License under Idaho Code Title 54 Chapter 19, which requires a financial statement, trade and business examinations, and a classification limit set by the Idaho Contractors Board. For all other construction work — private residential and commercial — contractors must register with the state under the Idaho Contractor Registration Act (Idaho Code Title 54 Chapter 52). Registration is not a license: there is no examination, but registrants must carry general liability insurance and disclose ownership and disciplinary history.

The Licensing Authority

Licensing for this trade is governed by Idaho Division of Occupational and Professional Licenses (DOPL), the agency that issues and regulates the credential under Idaho Code Title 54 (Chapters 10 Electrical, 26 Plumbing, 45 Public Works Contractors, 50 HVAC, 52 Idaho Contractor Registration). DOPL houses the Idaho Contractors Board, Electrical Board, Plumbing Board, and HVAC Board. It issues public works contractor licenses, contractor registrations, and individual trade licenses statewide, administers examinations, and handles discipline.

The Licensing Examination

PSI Services LLC (under contract to DOPL for the Public Works examinations) administers the required examination. Each part below must be passed before the license will issue:

Idaho Public Works Trade Examination (classification-specific: General Building, General Engineering, or specialty) — 80 questions, 240 minutes, passing score 70%

Examination fee: $75 per examination section paid to PSI at the test center.

Retake policy: Failed sections may be retaken by paying a new $75 fee per section. Application remains valid for one year.

Financial Security and Insurance

There is no statewide surety bond tied to this credential in the cited record. Bonding can still surface at the project level — permit, license, or public-works bonds — so check before you bid.

General liability

Idaho Contractor Registration requires proof of general liability insurance with minimum limits of $300,000. Public Works contractors must meet project-specific bonding and insurance requirements set by the awarding agency.

Workers' compensation

Workers' compensation is mandatory in Idaho for any business with employees under Idaho Code Title 72.

Public Works Contractor License applicants must submit a current financial statement. The dollar-limit classification issued by the Idaho Contractors Board is based on working capital and net worth.

Common Application Pitfalls

These are the recurring mistakes that most often delay or reject a Idaho General Contractor application, based on the official instructions cited here.

Assuming Registration equals a license

Idaho Contractor Registration is not a license and does not authorize public works over $50,000.

Missing insurance

DOPL will reject any Registration filing without a current $300,000 general liability certificate.

Working public works without the Public Works license

Bidding any public works project over $50,000 without the license is a criminal violation under Idaho Code §54-1902.

Exceeding the dollar-limit classification

The Idaho Contractors Board sets a specific dollar limit per licensee based on working capital. Exceeding it is a disciplinary violation.

Letting annual renewal lapse

Both credentials renew annually and lapse on the anniversary date. Continuing to work on a lapsed registration voids insurance coverage.
