Threshold. The registration chapter exempts a person performing work on one undertaking or project considered casual, minor, or inconsequential, whether by one or more contracts, whose aggregate contract price for labor and materials and all other items is less than two thousand dollars ($2,000), so long as the person is not acting with the intent to evade the chapter and does not hold himself out as a registered contractor. The exemption does not apply when the work is part of a larger construction project, whether undertaken by the same or a different construction contractor, or when the operation is divided into contracts of less than $2,000 for the purpose of evasion of the chapter or otherwise.

Idaho's credential for contractors is a contractor registration. The Idaho Contractors Board describes the Idaho Contractor Registration Act as one that "requires registration, not licensure" [1]. The Act set January 1, 2006 as the starting point: from that date the statute makes it unlawful for any person to engage in the business of, or hold himself out as, a contractor within the state without being registered [2]. The agency is the Idaho Contractors Board, within the Division of Occupational and Professional Licenses (DOPL).
The registration chapter carves out an exemption for small jobs. It covers work on one undertaking or project considered casual, minor, or inconsequential, whether under one contract or several, when the aggregate contract price for labor, materials and all other items is less than $2,000 [3]. That exemption holds only so long as the person is not acting with the intent to evade the chapter and does not hold himself out as a registered contractor [3]. It does not apply when the work is part of a larger construction project, whether the same or a different construction contractor undertakes it, or when the operation is split into contracts under $2,000 for the purpose of evasion of the chapter or otherwise [3].
Registration scope and insurance proof
The registration's scope is any person who engages in the business of, or holds himself out as, a contractor within the state [2].
Applicants file proof of insurance. For workers' compensation, it is a certificate from an insurer authorized to do business in Idaho, or other satisfactory proof, that coverage is in effect, or else a statement by the contractor explaining why that coverage is not required for the applicant [1]. For general liability, it is a certificate from an authorized insurer showing a policy covering the applicant's construction operations in the sum of not less than $300,000 single limit [1].
What registration costs and how long it runs
The Board's fee schedule, effective July 1, 2026, sets the same amounts for individuals and businesses and covers the initial application, renewal on an annual or a biennial cycle, and reinstatement [4]. As of July 1, 2026, the Application or initial registration (individual or business) fee is $120 per application [4]. The reinstatement charge is added on top of the renewal fee rather than replacing it; the fee table on this page lists each amount.
By statute, a registration runs for not less than twenty-four (24) months nor more than five (5) years, as the Board determines [5]. The Board's home page adds that as of October 14, 2025, it has begun transitioning to biennial registration [4].
Penalties and court actions
Idaho treats acting in the capacity of a contractor without a current registration as a misdemeanor [6]. On conviction, the court may impose a fine of not more than $1,000, imprisonment in the county jail for not more than six months, or both, in its discretion [6].
The statute also reaches payment disputes. A person acting as a contractor, unless otherwise exempt, may not bring or maintain an action in an Idaho court to collect compensation for work that requires registration without alleging and proving that the person was registered, or otherwise exempt under the chapter, at all times while performing the work [6].
