ConditionalIdaho Contractors Board — Division of Occ…
Under the Idaho Contractor Registration Act (Idaho Code Title 54, Chapter 52), anyone who builds, alters, repairs, improves, or demolishes a structure or improvement to real property must register with the Idaho Contractors Board, part of the Division of Occupational and Professional Licenses (DOPL). Registration requires proof of general liability insurance including products and completed operations of at least $300,000 single limit, plus workers' compensation or a statement why it is not required — there is no exam and no experience requirement. DOPL's fees effective July 1, 2026 are $120 to apply and $60 per year to renew, and the Board began moving registrants to biennial terms on October 14, 2025.
Public works are a separate license: Idaho Code § 54-1902 makes it unlawful to act as a public works contractor without a DOPL public works license, except on projects estimated under $100,000 (§ 54-1903(9)). On residential jobs over $2,000 a general contractor must give the homeowner the lien, insurance, and bond disclosures in § 45-525 before contracting. Electrical, plumbing, and HVAC work must be done by holders of those separate state licenses.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Idaho Code § 54-5213(1) bars cities, counties, and other local governments from running their own contractor registration or licensing programs (since January 1, 2007). They still issue building permits, and § 54-5209 requires the permit office to request your Idaho registration number and print it on the face of the permit — or mark it 'no contractor registration provided' for an exempt person — and the permit must be posted at the site.
The local offices section below names the exact permit desk for every Idaho county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Idaho registers contractors — proof of insurance and a fee — but gives no exam and sets no experience requirement for this trade.
Public projects estimated under $100,000 need no public works license (§ 54-1903(9)); above it, a DOPL public works license is required before you act as a public works contractor.
DOPL's contractor registration fees effective July 1, 2026: $120 application/initial, $60 annual or $120 biennial renewal, $40 reinstatement.

Acting as a contractor without a current registration is a crime.
An unregistered, non-exempt contractor cannot sue in an Idaho court to collect for work that required registration without proving registration throughout the work.
An unregistered contractor is deemed to have conclusively waived the right to file a mechanic's lien on the property.

Pending verification: How DOPL's $120 initial registration fee squares with IDAPA 24.21.01.400, which lists the application (including original registration) at $60 'not to exceed' — presumed to be two aggregated annual fees for a biennial first term ('Annual fees may be aggregated for biennial licensure'), but not confirmed · How DOPL assigns renewal dates during the biennial registration transition begun October 14, 2025 (the Board News FAQ was not retrieved); § 54-5211 allows terms of 24 months to 5 years · Whether DOPL's current application requires anything beyond the insurer certificate in § 54-5210(1)(e), such as naming the Board as certificate holder (application form not retrieved) · Public works contractor license fees, class dollar limits, and qualification requirements (IDAPA 24.39.50 and § 54-1904 not read)
