Idaho Contractor Licensing Guide: How to Get Licensed by Trade
In Idaho, most contractors performing public works projects valued at $100,000 or more must hold a license issued by the Idaho Division of Building Safety (DBS). Unlike many states, Idaho does not require a statewide general contractor license for private work—but public works contracts mandate DBS licensure by specific trade classification. Small business owners must navigate distinct pathways depending on whether they perform electrical, plumbing, HVACR, roofing, or other licensed trades.
License Categories & Eligibility by Trade
Idaho’s DBS issues public works contractor licenses in 12 defined trade classifications, including General Building, Electrical, Plumbing, HVACR, Roofing, Concrete, Masonry, Carpentry, Drywall, Painting, Flooring, and Excavation. To qualify, applicants must demonstrate at least four years of verifiable experience in their chosen trade—two years as a journeyman or supervisor and two years managing projects. For corporations or LLCs, a qualifying individual (QI) must be designated and meet all experience and examination requirements. The QI must be an officer, owner, or full-time employee with direct supervisory authority over licensed work. Sole proprietors apply directly; partnerships and entities must submit formation documents and designate one QI per license. Notably, Idaho does not license residential-only contractors separately—public works eligibility applies uniformly across trade types. Applicants must also pass a background check and provide references from licensed Idaho contractors or building officials verifying experience. Out-of-state experience is accepted if documented with pay stubs, W-2s, or signed affidavits from employers.
Bond, Insurance & Financial Requirements
All Idaho public works contractor licensees must maintain a $300,000 surety bond payable to the State of Idaho, filed with the DBS before license issuance. The bond must remain active for the license duration and name the State as obligee. In addition, contractors must carry minimum general liability insurance: $300,000 per occurrence and $600,000 aggregate for bodily injury and property damage. Workers’ compensation insurance is mandatory for any employer with one or more employees—even part-time or seasonal workers—as required under Idaho Code § 72-301. Proof of both bond and insurance must be submitted via certified documentation from licensed insurers; policies must list the DBS as certificate holder and include automatic renewal notifications. Failure to maintain continuous coverage results in immediate license suspension. Small businesses may obtain bonded capacity through approved surety providers listed on the DBS website, and many insurers offer bundled packages for liability and workers’ comp tailored to Idaho trade contractors. Note: Home improvement registration (separate from DBS) is required for residential remodeling over $1,000 but does not replace public works licensure.
Examination Process & Application Steps
Applicants must pass two exams: a Business & Law exam (60 multiple-choice questions, 70% passing score) and a Trade-specific exam aligned with their classification (e.g., Electrical, Plumbing), administered by PSI Services. Exams are closed-book, computer-based, and offered at testing centers in Boise, Coeur d’Alene, and Pocatello—or remotely with live proctoring. Study materials include the Idaho Administrative Rules Title 21, Chapter 10, the 2021 International Building Code (IBC), and trade-specific ICC standards. Candidates must schedule exams after DBS pre-approval, which requires submission of Form DBS-1, experience verification, fingerprints, and $150 non-refundable application fee. Upon passing both exams, applicants submit final documentation—including bond, insurance certificates, and $250 initial license fee—within 90 days. Licenses are issued within 10 business days of complete submission. First-time applicants should allow 3–4 months total processing time. Retakes are permitted after a 30-day waiting period, with additional $75 exam fees per attempt.
License Renewal, Compliance & Enforcement
Idaho public works contractor licenses expire biennially on June 30 of odd-numbered years (e.g., 2025, 2027) and require renewal every two years. Renewal involves submitting Form DBS-2, updated bond and insurance certificates, proof of continuing education (6 hours per cycle, including 2 hours of Idaho-specific law), and a $200 fee—all due no later than May 31 to avoid late penalties. The DBS mandates CE hours be completed through DBS-approved providers such as the Associated General Contractors of Idaho or online platforms like PDHengineer. Failure to renew results in automatic license expiration; reinstatement requires reapplication, new background check, and payment of delinquency fees. DBS conducts random audits and investigates complaints via its Enforcement Unit—violations like unlicensed public works performance, misrepresentation, or insurance lapses may trigger fines up to $5,000 per offense or license revocation. Contractors must notify DBS within 10 days of changes to business structure, QI, address, or insurance carrier. All license status and disciplinary history is publicly searchable via the DBS Online License Lookup tool.

Do I need a DBS license to do residential remodeling in Idaho?
No—you only need a DBS public works license for contracts with state or local government entities valued at $100,000 or more. However, Idaho law requires home improvement registration with the Idaho Bureau of Occupational Licenses for any residential remodeling job over $1,000, including contracts, estimates, and advertising.
Can I use my out-of-state contractor license to bid on Idaho public works projects?
No. Idaho does not offer reciprocity for contractor licenses. Even licensed contractors from Washington, Oregon, or Utah must meet all Idaho DBS requirements—including Idaho-specific exams, bond, insurance, and experience verification—before bidding on public works projects.
What happens if my qualifying individual leaves my company during the license term?
You must appoint a new qualifying individual within 30 days and submit Form DBS-3 with supporting documentation to DBS. Failure to do so results in automatic license suspension. The new QI must pass both exams unless previously licensed in Idaho and in good standing for the same trade classification.
