Idaho Carpentry License Requirements (2026)

Idaho does not issue a carpentry trade license. Contractor registration with DOPL is required for a construction job exceeding $2,000, unless an exemption applies. There is no general trade exam, experience requirement, or contractor bond. DOPL requires $300,000 single-limit general liability insurance and workers’ compensation coverage or a statement explaining why it is not required. Local permits and specialty licensing remain separate.

Federal requirement: EPA Lead RRP Rule

Pre-1978 housing triggers the federal EPA Lead RRP Rule for any paint-disturbing renovation, repair, or painting work — a requirement that stands apart from whatever Idaho does or does not license. See our complete EPA RRP Lead Certification guide for who needs firm and renovator certification, what it costs, and how renewal works.

Common Compliance Mistakes

The issues below are the most likely to create an unlicensed-work, registration, permit, or scope problem for Idaho Carpentry work, based on the official sources cited on this page.

Skipping registration

Idaho Code §54-5217 makes unregistered contracting a misdemeanor and voids the contractor mechanics lien rights.

Missing the Public Works license

Government projects require the separate PWCLB license — registration alone is not enough.

Lead RRP for pre-1978 trim

EPA RRP certification is federally required for any carpentry that disturbs painted surfaces in pre-1978 housing.

Workers compensation

Even one employee triggers Idaho Code §72-301. DOPL freezes registration without coverage.

Lapsed GL insurance

A lapsed general liability policy automatically suspends the registration until reinstated.
