Idaho

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.

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

Contractors
Regulators

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 and Who regulates construction.

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.

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.

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.

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 for complete fee tables.

What are the bonding and insurance requirements?

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.

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.

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.

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 for the complete table.

Does Idaho require a construction manager license?

Yes. Construction managers must be licensed through Public Works Contractor Licensing at DOPL. Requirements include a bachelor’s degree plus 4 years experience, or 5 years without a degree, plus the CMAA exam. A one-year temporary license may be available for managers licensed in states with similar requirements. See Requirements.

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.

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.

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.

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.

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 for complete fee tables by trade.

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.

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.

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.

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.

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.

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.

Contractors
Regulators

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.

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.

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.

All general contractors and subcontractors must register with the General Contractors Board. Confirm $300,000 general liability insurance and workers’ compensation coverage.

Check the public works threshold

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.

Route trade licenses to DOPL

Electrical, plumbing, and HVAC work each require separate trade licenses. Check reciprocity for journeyman credentials if you hold an out-of-state license.

Confirm the requirement set

Confirm exams, experience, fees, bonds, insurance, renewal cycle, and reciprocity rules for each license type before filing.

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

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

Common determination scenarios

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

Private home or commercial project

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.

Public works project

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.

Electrical, plumbing, or HVAC work

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.

Out-of-state contractor entering Idaho

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).

Construction management

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.
