# Idaho

> Contractor licensing thresholds, regulator routing, requirements, reciprocity, and license types for Idaho's layered registration and licensing model.

Idaho uses a layered model: all contractors must register with the General Contractors Board, public works projects of **\$50,000** or more require a separate class-based license, and electrical, plumbing, and HVAC trades carry their own licenses through the Division of Occupational and Professional Licenses.

<Warning>
  Always verify statutes, fees, and application details with the live regulator before making bidding, licensing, or legal decisions.

<Tabs>
  <Tab title="Contractors" icon="hard-hat">
    <AccordionGroup>
      <Accordion title="How do I register as a contractor in Idaho, and which agency do I contact?">
        All general contractors and subcontractors must register with the General Contractors Board (part of DOPL) at 11341 W. Chinden Blvd., Bldg. #4, Boise, ID 83714. Registration requires **\$300,000** minimum general liability insurance and workers' compensation coverage. The fee is **\$50** per year. See [Requirements](#requirements) and [Who regulates construction](#who-regulates-construction).
      </Accordion>

      <Accordion title="What is a public works license in Idaho, and when is one required?">
        A public works license is required for all contractors and subcontractors on public works projects of **\$50,000** or more. It uses a class system (D through Unlimited) with financial requirements scaling by bid limit. You must pass an exam with a 70% score. This is separate from general contractor registration. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="Does Idaho require separate licenses for electrical, plumbing, and HVAC contractors?">
        Yes. Electrical, plumbing, and HVAC work each require separate trade licenses through DOPL, in addition to general contractor registration. Journeyman applicants need 4 years (8,000 hours) plus 4 years vocational training, or 8 years (16,000 hours) experience alone. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="Where do I go to get licensed in Idaho?">
        General contractor registration goes through the General Contractors Board. Electrical, plumbing, HVAC, and public works licensing goes through DOPL. Both are located at 11341 W. Chinden Blvd., Bldg. #4, Boise. See [Who regulates construction](#who-regulates-construction).
      </Accordion>

      <Accordion title="How much does it cost to register and get licensed?">
        Contractor registration is **\$50** per year. Public works license fees range from **\$50** (Class D) to **\$550** (Unlimited). Electrical journeyman is **\$55** initial. Plumbing journeyman is **\$29.40** initial. HVAC journeyman is **\$150** initial. See [Requirements](#requirements) for complete fee tables.

        Registration requires **\$300,000** minimum general liability insurance. Plumbing and HVAC contractors must post a **\$2,000** surety bond each. Public works licensing has financial requirements scaling by class. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="Can I use my out-of-state license in Idaho?">
        Contractor registration has no reciprocity. For trade licenses, check if your state has reciprocity: electrical has 14 reciprocal states, plumbing has 3 (Montana, Oregon, Washington). Applicants from non-reciprocal states must meet vocational requirements or provide double the experience (8 years / 16,000 hours). See [Reciprocal agreements](#reciprocal-agreements).
      </Accordion>

      <Accordion title="Does Idaho require a license for roofing work?">
        Roofing is a subcontractor registration category (110 Roofing) under the General Contractors Board. All roofing contractors must register. If the project is public works at **\$50,000** or more, a public works license is also required. See [Types of licenses](#types-of-licenses).
      </Accordion>

      <Accordion title="What are the public works license classes and bid limits?">
        Classes range from D (up to **\$50,000**) to Unlimited (no bid limit). Net worth requirements range from **\$10,000** (Class D) to **\$1,000,000** (Unlimited). Higher classes require audited or reviewed financial statements. See [Requirements](#requirements) for the complete table.
      </Accordion>

      <Accordion title="Does Idaho require a construction manager license?">
        Yes. Construction managers must be licensed through Public Works Contractor Licensing at DOPL.

A one-year temporary license may be available for managers licensed in states with similar requirements. See [Requirements](#requirements).
      </Accordion>
    </AccordionGroup>
  </Tab>

  <Tab title="Regulators" icon="shield-check">
    <AccordionGroup>
      <Accordion title="How does Idaho divide contractor regulation between the General Contractors Board and DOPL?">
        The General Contractors Board handles universal registration for all home and commercial contractors. DOPL handles electrical, plumbing, HVAC, and public works licensing. Registration is a low-barrier entry point; trade and public works licenses add exam and financial requirements. See [Who regulates construction](#who-regulates-construction).
      </Accordion>

      <Accordion title="What is the threshold for requiring a public works license?">
        **\$50,000** or more per project. This applies to both prime contractors and subcontractors on the project. The class system (D through Unlimited) determines bid limits based on financial requirements. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="How does Idaho's Construction Manager licensing work?">
        Construction managers must be licensed through Public Works Contractor Licensing. The education path requires a bachelor's degree in architecture, engineering, or construction management plus 4 years of experience. The experience-only path requires 5 years. The CMAA exam is required. A one-year temporary license is available for managers from states with similar requirements. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="How does Idaho's layered model compare to single-board states?">
        Idaho's model is unusually layered: universal registration (no threshold, no exam) plus trade licensing (exams, experience) plus public works licensing (classes, financial statements). This contrasts with single-board states like Nevada or California. The registration layer is one of the lightest entry points nationally.
      </Accordion>

      <Accordion title="What are the fees across trades and public works classes?">
        Registration is **\$50** per year. Public works fees range from **\$50** (Class D) to **\$550** (Unlimited). Electrical journeyman is **\$55**. Plumbing journeyman is **\$29.40**. HVAC journeyman is **\$150**. See [Requirements](#requirements) for complete fee tables by trade.
      </Accordion>

      <Accordion title="What license classifications does Idaho use?">
        Registration categories include 4 general contractor types and over 40 subcontractor specialties. Public works has 5 major classifications (Heavy, Highway, Building, Specialty, Construction Management) with 8 class levels. Trade licenses cover electrical, plumbing, and HVAC at apprentice through contractor levels. See [Types of licenses](#types-of-licenses).
      </Accordion>

      <Accordion title="How does reciprocity work in Idaho?">
        Reciprocity is trade-specific only. Electrical journeyman has 14 reciprocal states (including Colorado, Montana, Wyoming). Plumbing journeyman has 3 states (Montana, Oregon, Washington). Contractor registration and public works licensing have no reciprocity. See [Reciprocal agreements](#reciprocal-agreements).
      </Accordion>

      <Accordion title="What exam requirements exist across the different license types?">
        General registration requires no exam. Public works requires a 70% exam score. Electrical journeyman requires 70%, master requires 75%. Plumbing journeyman requires a written and practical exam at 75%. HVAC journeyman requires 70%. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="What are the renewal cycles?">
        Registration is annual (1 year from issue date or birthday). Electrical licenses are 1-3 years depending on type. Plumbing is 3 years. HVAC is 1-5 years depending on type. Public works licenses are valid for 1 year. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="How does Idaho compare to other Western states?">
        Idaho is more layered than most: universal registration plus trade-specific and public works licensing. The **\$50,000** public works threshold is moderate. The double-experience requirement for non-reciprocal out-of-state applicants (8 years / 16,000 hours) is notably strict. See [Licensing thresholds](/docs/compare/licensing-thresholds).

## Special considerations

Different roles need different things from an Idaho page. Use the tab that matches your situation to see what matters most before you read the full detail below.

<Tabs>
  <Tab title="Contractors" icon="hard-hat">
    <Tip>
      Idaho has two layers: registration (required for all work) and licensing (required for public works and trades). Make sure you have both when they apply.
    </Tip>

    * All general contractors and subcontractors must register — there is no dollar minimum for registration.
    * Public works projects of **\$50,000** or more require a separate class-based license (D through Unlimited).
    * Registration requires **\$300,000** minimum general liability insurance and workers' compensation coverage.
    * Electrical, plumbing, and HVAC work requires separate trade licenses in addition to registration.
    * Out-of-state applicants from non-reciprocal states must provide double the standard experience (8 years / 16,000 hours) for trade licenses.
    * Plumbing and HVAC contractors must post a **\$2,000** surety bond.
    * Construction managers must be separately licensed through Public Works Licensing.
  </Tab>

  <Tab title="Regulators" icon="shield-check">
    <Info>
      Idaho is best understood as a layered system: universal contractor registration plus trade-specific and public-works licensing through DOPL.
    </Info>

    * The General Contractors Board handles registration for all home and commercial contractors.
    * The Division of Occupational and Professional Licenses (DOPL) handles electrical, plumbing, HVAC, and public works licensing.
    * Public works licensing uses a tiered class system (D through Unlimited) with financial requirements scaling by bid limit.
    * Reciprocity exists for electrical journeyman (14 states) and plumbing journeyman (3 states) but not for contractor registration.

## Readiness checklist

Four things you need to confirm before you can treat Idaho as "ready" for a bid or an application. If any of these are unclear, you are not ready yet.

<Steps>
  <Step title="Register as a contractor" icon="tag">
    All general contractors and subcontractors must register with the General Contractors Board. Confirm `$300,000` general liability insurance and workers' compensation coverage.
  </Step>

  <Step title="Check the public works threshold" icon="receipt">
    If the project is public works valued at `$50,000` or more, you need a separate class-based license from DOPL. Determine the correct class (D through Unlimited) based on bid limits and financial requirements.
  </Step>

  <Step title="Route trade licenses to DOPL" icon="building">
    Electrical, plumbing, and HVAC work each require separate trade licenses. Check reciprocity for journeyman credentials if you hold an out-of-state license.
  </Step>

  <Step title="Confirm the requirement set" icon="clipboard-check">
    Confirm exams, experience, fees, bonds, insurance, renewal cycle, and reciprocity rules for each license type before filing.
  </Step>
</Steps>

<Check>
  If you can confirm registration, public works class, trade licenses, and requirement details, you have the minimum package needed for an Idaho readiness check.

## Construction work regulated

Idaho requires universal contractor registration for all construction work, plus additional licensing for public works and regulated trades. The public works threshold is the key dollar gate.

| Work lane                        | What triggers regulation                              |
| -------------------------------- | ----------------------------------------------------- |
| Home and commercial construction | Registration required — no dollar minimum             |
| Public works                     | License required for projects of **\$50,000** or more |
| Electrical                       | Trade license required                                |
| Plumbing                         | Trade license required                                |
| HVAC                             | Trade license required                                |
| Construction management          | Must be licensed through Public Works Licensing       |

<Note>
  Registration and trade licensing are separate. A contractor performing electrical work on a private project needs both a contractor registration and an electrical license.
</Note>

## Common determination scenarios

If you are trying to figure out where to start, expand the scenario that is closest to your situation.

<AccordionGroup>
  <Accordion title="Private home or commercial project" icon="house">
    Register with the General Contractors Board. You need a completed application, proof of **\$300,000** minimum general liability insurance with completed operations and general aggregate coverage, and workers' compensation coverage or an acceptable exemption statement. Registration is valid for one year.
  </Accordion>

  <Accordion title="Public works project" icon="building">
    In addition to contractor registration, obtain a Public Works License through DOPL. Choose the correct class (D through Unlimited) based on bid limits. Higher classes require CPA-audited or reviewed financial statements. All applicants must pass an exam with a 70% score.
  </Accordion>

  <Accordion title="Electrical, plumbing, or HVAC work" icon="bolt">
    Each trade requires a separate license through DOPL. Journeyman applicants need 4 years (8,000 hours) of experience plus 4 years of vocational training, or 8 years (16,000 hours) of experience alone. Check reciprocity — electrical has 14 reciprocal states and plumbing has 3.
  </Accordion>

  <Accordion title="Out-of-state contractor entering Idaho" icon="arrow-left-right">
    Contractor registration has no reciprocity — you must register like any other applicant. For trade licenses, check if your state has reciprocity. Applicants from non-reciprocal states must meet Idaho's vocational education requirements or provide double the experience (8 years / 16,000 hours).
  </Accordion>

  <Accordion title="Construction management" icon="building">
    Construction managers must be licensed through Public Works Contractor Licensing. Requires a bachelor's degree in architecture, engineering, or construction management plus 4 years of experience; or 5 years of experience without a degree. Must pass the CMAA exam. A temporary one-year license may be issued to managers licensed in states with similar requirements.

## Reciprocal agreements

Idaho's reciprocity is trade-specific. Contractor registration has no reciprocity — all applicants must register regardless of out-of-state credentials. Electrical journeyman licenses have the broadest coverage at 14 states.

<Info>
  Reciprocity applies only to journeyman-level trade licenses. Contractor registration and public works licensing have no reciprocal agreements.
