Idaho contractor license requirements

Licenses and registrations

Contractor Registration (Individual or Business)

Anyone who contracts to perform construction work, including general contractors, remodelers and specialty trades not covered by another Idaho license.

• When it applies: Required unless the aggregate contract price for labor and materials and all other items is less than two thousand dollars (Idaho Code 54-5205). The board FAQ states jobs exceeding $2000.00 (materials & labor).
• Good to know: Registration, not licensure. Licensed electrical contractors, plumbers, HVAC installers, public works contractors and similar licensees do not need to register unless they work beyond the scope of their license.

What you need to qualify

• Insurance: General liability insurance, including products and completed operations, of not less than $300,000 single limit. Workers' compensation insurance, or a statement explaining why coverage is not required.
• Business registration: The application requires a Social Security number (individuals) or employer tax ID (businesses), the business name and address, and the names and addresses of all owners.
• Also required: Applicants must disclose any past denial or revocation of a contractor license or registration. The registration number must be displayed within 60 days at the place of business and on advertising, contracts, building permits, letterheads, purchase orders and subcontracts.

Fees, renewal and continuing education

• Fees: Effective July 1, 2026: application/initial registration $120 (individual or business), annual renewal $60, biennial renewal $120. Reinstatement fee $40 in addition to the renewal fee.
• Renewal: Historically annual. As of October 14, 2025, the board began transitioning to biennial (two-year) registration.

Contracts and homeowner protections

Before entering a contract over $2,000 with a homeowner or residential purchaser, a general contractor must give a written disclosure (Idaho Code 45-525) and get a signed receipt. It must explain the owner's rights to request lien waivers, proof of general liability and workers' compensation insurance, extended title insurance, and a surety bond at the owner's expense. Before final payment, the contractor must give a completion disclosure listing subcontractors and suppliers who provided work or materials valued over $500. Failing to give these disclosures is a deceptive practice under the Idaho Consumer Protection Act.

Electrical, plumbing and HVAC work

Electrical, plumbing and HVAC work are licensed separately by DOPL through the Idaho Electrical Board, Idaho Plumbing Board and Idaho HVAC Board.

Working without a license

Working without a required registration is a misdemeanor punishable by a fine of up to $1,000, up to six months in county jail, or both. Unregistered contractors cannot get building permits, lose lien rights, and cannot sue to collect payment on contracts that required registration.

What to confirm with the state

We couldn't confirm these on an official page when we checked. Ask the licensing office before you rely on them:

• Local (city or county) contractor licensing requirements in Idaho were not confirmed on an official page.
• Whether any bond or financial statement is required (none was mentioned on official pages).
• Details of the biennial renewal transition schedule (described only in a linked board news item).
