If you’re looking to get into one of the most lucrative trade industries in the country, getting your Idaho general contractor license is a great bet. Idaho’s construction industry nearly doubled employment over the last 10 years, and the state is continuing to try and grow its workforce. 

According to the Economic Research Institute, the average salary for Idaho general contractors is about $117,000—and the top earners in the state average closer to $143,000.

In this guide, we’ll cover the key things you need to know about becoming a licensed general contractor in Idaho.

Do you need a general contractor license in Idaho?

While you don’t necessarily need a license, you do need to register with the state of Idaho to do construction work on any residential or commercial projects valued at over $2,000. 

In Idaho, Construction is defined as “the performance of building, altering, repairing, adding to, subtracting from, improving, reconstructing, moving, excavating, wrecking or demolishing any building, highway, road, bridge, or other structure, project, development or improvement to real property, or to do any part thereof, including the erection of scaffolding or other structures or works in connection therewith.”

Specific trades and building projects, like HVAC, electrical, and public works, require their own licenses. 

Working on construction projects without being registered is illegal and can bring fines and other penalties.

Contractor licensing and registration are handled by the Idaho Division of Occupational and Professional Licenses (DOPL). This division is responsible for licensing general contractors overseeing building projects and specific subcontractor trades like roofing, framing, and painting. 

Depending on the project, the DOPL and regional governments may also be involved in building plan review and permit applications. 

Note that there are several exemptions from registering. For example, if you are an employee of a contractor and are paid in wages; or if you are an owner doing work on your own land and intend to sell the property within 12 months. Check the DOPL site closely to see if you are exempt.

The DOPL has a licensing FAQ page that can help you answer any other questions about the need for licensing in Idaho. 

Types of contractor licenses in Idaho

There are different types of contractor registrations available depending on the type of project and whether it is publicly or privately funded. Private building projects are overseen by registered general contractors, while public works are overseen by construction managers with a license class that depends on the monetary value of the project. 

Here are the different types of contractors you can register as in Idaho

  • General Commercial Builder
  • General Residential Builder
  • General Remodel Builder
  • Subcontractor

Public works construction management licenses cover most general contracting projects that involve public funding. With this license, you can work on all building projects that require the use of more than two different building trades.

This license type is broken into different classes based on the financial value of the project:

Does Idaho reciprocate general contractor licenses?

Reciprocal licenses let contractors with out-of-state licenses apply directly for an equivalent one in another state. 

Currently, Idaho only reciprocates licenses for electricians and plumbers. So, if you have an out-of-state general contractor license, you’ll need to follow the application steps outlined above. 

How much does a general contractor license cost in Idaho?

The amount you have to spend to get and maintain a general contractor license in Idaho varies depending on the type and classification of the license you have, but you can expect to pay between $125 and $625 for initial licensing. 

Here’s a closer look at the fees associated with each license type and class:

Keep in mind that there are also bond, insurance, and other financial requirements that you may need to meet in order to get your license. 

Renewing your general contractor license

General contractor registration and public works construction manager licenses are renewed annually, and it’s important to get the renewal done on time—licenses that have expired for longer than six months may not be reinstated. 

The public works contractor renewal form outlines all the steps in the process, including the financial benchmarks you need to meet in order to maintain a specific class of license. You must also show proof of current liability insurance and workers’ compensation insurance (if applicable) to successfully renew your license. 

Instead of following the typical renewal process, public works licenses can also be downgraded by one or more classes to reduce the financial requirements you need to meet. 

Manufactured home installer licenses need to be renewed on an annual basis, and this can be done up to six months before the actual expiration date. To qualify for renewal, you also need to complete eight hours of continuing education every three years and maintain a current $5,000 bond.  

You can find more information about this process on the DOPL’s license renewal information page

What happens if my general contractor license expires? 

If you think your construction manager, manufactured home installation, or general contractor documentation has expired, stop all work immediately. Without a valid license, you will not be able to obtain any building permits or collect money for any existing contracts. Plus, the fines for working without a license and breaking building laws can bring up to $20,000 in penalties per violation and even jail time.

You can then use the DOPLs online contractor license search to check the status of your license and follow the necessary renewal steps. 

How to start a contracting business in Idaho

Once you’ve built up your experience and earned your Idaho general contractor, construction manager, or manufactured home installer license, you can take the next step toward a more lucrative future by starting your own contracting business. 

The DOPL has a Contractor’s Business and Law Reference Manual that includes a checklist with some of the key steps you need to take: 

  • Research the market and write a business plan
  • Select your legal entity
  • Register with the Secretary of State 
  • Arrange for income, sales, and excise taxes
  • Understand employer responsibilities for employee taxes, workers’ comp, and insurance
  • Secure all necessary federal, state, and regional permits

Once you’re registered, there are few more things you’ll need to think about to truly set your business up for success:
