How to Verify a Contractor License in Idaho

TL;DR — Verifying a Contractor License in Idaho in 60 Seconds

Idaho requires all contractors performing work valued at more than $2,000 to register with the Idaho Contractors Board, which operates under the Division of Occupational and Professional Licenses (DOPL). Trade professionals — electricians, plumbers, and HVAC technicians — must hold separate state licenses through the Division of Building Safety. To verify any Idaho contractor or trade professional, search their name or license number on LicensedCheck.com or the DOPL license verification portal.

Idaho also requires a separate Public Works Contractor License for anyone working on government-funded projects. This license is classified from A through D based on the contractor's financial capacity and project size. Always confirm the specific license type and status before hiring.

Which Idaho Trades Require State Licenses

Idaho requires contractor registration for anyone who constructs, alters, repairs, or demolishes any building, highway, road, or structure where the total project cost exceeds $2,000. This is one of the lowest thresholds in the country, meaning nearly all professional construction work requires state registration.

General contractors register through the Idaho Contractors Board under DOPL. This is a registration rather than a traditional license — Idaho does not require general contractors to pass a trade exam, but they must carry general liability insurance and comply with state business requirements. Specialty trade contractors have more rigorous requirements.

Electricians must be licensed through the Division of Building Safety at apprentice, journeyman, master, or contractor levels. Idaho requires passing a state exam for journeyman and above. Plumbers follow a similar structure — apprentice registration, then journeyman and contractor licenses requiring exams and documented work experience of 8,000 hours for journeyman. HVAC technicians are also licensed at apprentice, journeyman, and contractor levels with exam requirements.

Public Works Contractors need a separate license classified from A through D based on project value and financial capacity. This license requires passing two written examinations, submitting financial statements, and providing contractor references.

Protecting Yourself When Hiring in Idaho

Idaho's $2,000 registration threshold means nearly every contractor you hire for meaningful work should be registered with the state. Before hiring, verify three things: the contractor's registration is active, they carry current general liability insurance, and if they have employees, they have workers' compensation coverage.

For trade work — electrical, plumbing, HVAC — verify the specific trade license as well. A general contractor registration does not authorize someone to perform licensed trade work. The contractor or their subcontractors must hold the appropriate trade licenses.

Idaho law requires contractors to provide a written disclosure statement for any residential contract over $2,000. The homeowner must sign an acknowledgment of receipt. If a contractor skips this step, that is a red flag.

Get a detailed written contract that includes the full scope of work, total price, payment schedule, start and completion dates, and the contractor's registration number. Request certificates of insurance and verify them directly with the insurance company.

Watch for these red flags in Idaho: a contractor who claims no registration is needed for work over $2,000, anyone who cannot provide their DOPL registration number, a contractor without proof of liability insurance, trade workers such as electricians, plumbers, or HVAC technicians who cannot show their Division of Building Safety license, and anyone who demands full payment before starting work. Verify first at LicensedCheck, then hire.
