Idaho contractor license requirements

Idaho regulates contracting through a state contractor registration (bond and insurance based, not a competency exam). This page lays out exactly what Idaho requires: the licensing agency, who must be licensed, experience, exams, fees, the financial responsibility mechanism, and reciprocity, every figure sourced and dated below.

Who must be licensed in Idaho

Idaho Division of Building Safety (DBS) is the licensing authority. Registration required for private residential and commercial contracting work; a separate Public Works Contractor License covers government-funded projects of $100,000 or more.

Experience and qualification

No experience verification for the Registered Entity (RCE) registration; the separate Public Works Contractor License requires financial qualification and an exam.

License classes

• RCE (Registered Entity): The standard private-work registration; no exam or bond.

Exam

No trade exam for RCE registration. The Public Works Contractor License, a different track for government-funded jobs of $100,000+, does require an exam and financial qualification.

Fees

• Application: $50
• Renewal (now biennial): $50

Financial responsibility

Idaho uses insurance in place of a bond ($300,000 general liability) as its financial-responsibility mechanism. $300,000 general liability insurance is required in lieu of a bond for RCE registration. Workers’ compensation is required if the contractor has employees.

Reciprocity and the NASCLA exam

Idaho is not on NASCLA’s participating-agencies list, confirmed directly against NASCLA’s own page, so a NASCLA Accredited Examination credential from another state does not by itself satisfy Idaho’s requirements. See contractor license reciprocity for what does carry over, and the 50-state comparison for which states do accept the NASCLA exam.
