North Dakota Contractor License: Complete 2026 SOS Guide

What is a North Dakota contractor license and who needs one?

A North Dakota contractor license is issued by the North Dakota Secretary of State (sos.nd.gov) and is required of anyone whose construction job has a cost, value, or price that exceeds $4,000, a threshold set by North Dakota Century Code chapter 43-07 that reaches general contractors, subcontractors, public contractors, and out-of-state contractors alike. The license comes in four classes set by the value of a single contract: Class D up to $100,000, Class C up to $300,000, Class B up to $500,000, and Class A with no value limit, and you pick the class that fits the largest job you plan to take. North Dakota does not make you sit a competency exam. Instead the application asks you to sign a statement of your experience and qualifications, file a certificate of liability insurance naming the Secretary of State, and show Workforce Safety and Insurance coverage, and the state charges no contractor surety bond because the old bond statute was repealed. The state fee is the class fee itself, $100 for Class D up to $450 for Class A, and that single fee covers issuance, so a small residential builder typically pays $100 in the first year while a large commercial firm pays $450. The license runs on an annual cycle that ends every March 1, and renewal costs $30 for Class D up to $90 for Class A. Working without the license once a job clears $4,000 is a class A misdemeanor, exposes you to a civil penalty of up to three times the license fee, and bars you from bringing any claim, action, or suit to collect on the job in a North Dakota court.

The four North Dakota license classes

North Dakota does not sort contractors by trade the way many states do. It sorts them by money. There is one license, administered by the Secretary of State, and it is issued in four classes that are defined entirely by the value of the largest single contract project you are allowed to take. Pick the class that matches your biggest job, because the class caps what you can legally build.

The classes run from Class D at the bottom to Class A at the top. A Class D holder cannot take on any single contract project worth more than $100,000. Class C tops out at $300,000, Class B at $500,000, and Class A carries no limit at all. The fee climbs with the ceiling: the more work a class lets you chase, the more the license costs to obtain and to renew each year.

The practical move is to license for the work you actually do. A remodeler who never touches a job above $250,000 has no reason to pay for Class A. A commercial builder bidding a $2 million project needs Class A and nothing less. If your business grows into bigger jobs, you can renew under a higher class by paying the fee for that class, so the license grows with you.

What you need to qualify

Because there is no exam, the license is a documentation exercise, not a testing one. The Secretary of State is confirming three things before it issues: that a real, registered business stands behind the license, that the public is covered by insurance if a job goes wrong, and that your workers are protected. Assemble all of it before you file.

You must be at least 18 and registered

An applicant has to be eighteen years of age or older and apply under oath. Before you touch the license application, your business needs to exist on paper with the Secretary of State: a sole proprietor may need to register a trade name, a general partnership may need a fictitious partnership name, and a corporation or limited liability company must register outright. The name on the license application has to match the name on that business registration.

A statement of experience and qualifications

In place of an exam, the application requires a signed statement of your experience and qualifications as a contractor, and you specify the class of license you are seeking. The registrar can ask for more, including criminal history record information at your expense, if it needs help deciding whether you are eligible to act as a contractor. Give complete answers the first time, because an incomplete application is the most common reason a license is held up.

Proof of insurance and workers coverage

You file a certificate of liability insurance with the application, issued in the same name you are requesting for the license, and it must list the North Dakota Secretary of State, 600 E Boulevard Ave, Dept 108, Bismarck, ND 58505, as the certificate holder. If you have employees residing in North Dakota, you attach a current certificate of payment from Workforce Safety and Insurance to prove workers’ compensation coverage. If you have no North Dakota employees and do not meet the tests of significant contact, you provide a letter of good standing from Workforce Safety and Insurance instead.

How to apply for a North Dakota contractor license: the 8-step process

The path is a paperwork sequence, and the order matters. Register the business first, gather your insurance proof, then file. Work it in this sequence and you avoid the two things that stall applications most: a business name that does not match, and missing insurance documents.

1. Confirm you need the license

   Check that the cost, value, or price of your job is more than $4,000. Above that line, the license is mandatory before you work or bid. Below it, you generally do not need the statewide license, though local rules can still apply.

2. Register your business with the Secretary of State

   Register a trade name, a fictitious partnership name, or your corporation or limited liability company, whichever fits your structure. The name here has to match the name you put on the license application, so settle it first.

3. Choose your license class

   Pick Class D, C, B, or A based on the value of the largest single contract you plan to take. Class D caps at $100,000, Class C at $300,000, Class B at $500,000, and Class A has no limit. The class sets your fee.

4. Gather your insurance and workers coverage

   Obtain a certificate of liability insurance in your business name that names the Secretary of State as certificate holder, and line up your Workforce Safety and Insurance proof: a certificate of payment if you have North Dakota employees, or a letter of good standing if you do not.

5. Prepare your statement of experience

   Write and sign the statement of your experience and qualifications as a contractor that the application requires. There is no test to schedule and no exam fee, so this signed record is what stands in for a competency check.

6. File through the FirstStop portal

   Submit the Contractor License Application through the Secretary of State’s FirstStop portal, attaching your liability insurance certificate and Workforce Safety and Insurance documentation. Make sure every field matches your business registration.

7. Pay the class fee and clear review

   Pay the fee for your class, from $100 for Class D to $450 for Class A. The registrar reviews eligibility and issues once your documents and fee are complete. A license issued in January or February runs through March 1 of the following year.

8. Add any trade or specialty credential

   If your work includes electrical, plumbing, asbestos abatement, or transient-merchant sales, obtain those separate credentials from the boards that govern them. They are not part of the contractor license and are covered below.

Once you are licensed, your first bid sets the tone. Turn a jobsite photo into an itemized estimate in about 6 seconds so your numbers look professional from day one. Free to try.

No exam: the experience statement and the trades that carry their own license

Here is the part that surprises contractors coming from a state like California or Virginia. North Dakota does not require a contractor to pass a competency exam. There is no business and law test, no trade test, and no vendor exam fee. In place of the exam, the application asks you to sign a statement of your experience and qualifications, and the registrar reviews that record along with your insurance and business registration. It is a license in name, but the entry gate is registration and documentation rather than a proctored test.

That puts North Dakota in a small group. Of the states that license general contractors at the state level, a minority skip the exam entirely, and North Dakota is one of them. It keeps the cost and the timeline down: with no exam to schedule, the main wait is the registrar’s review of your paperwork.

What the general contractor license does not do is cover the trades that North Dakota regulates through their own boards. If your work crosses into those trades, you carry a separate state credential on top of the contractor license. These are the common ones.

The Secretary of State is explicit that these specialized licenses are not part of the contractor license it issues. So a general contractor who also does electrical or plumbing work needs both the contractor license and the trade license, each from its own authority.

Insurance and Workforce Safety, not a bond

This is where North Dakota is unusual, and cheaper, than most states. It does not require a contractor’s surety bond. The bond statute that once did was repealed years ago, so there is no $10,000 or $25,000 bond premium to buy the way there is in many neighboring states. What the state requires instead is proof that you are insured and that your workers are covered.

Two documents carry that weight. The first is a certificate of liability insurance, issued in your business name, that names the North Dakota Secretary of State as the certificate holder. The second is Workforce Safety and Insurance coverage: a certificate of payment if you employ people who live in North Dakota, or a letter of good standing if you do not have North Dakota employees and do not meet the tests of significant contact. You keep the liability coverage active for as long as you hold the license, because letting it lapse is one of the grounds the registrar uses to classify a license as not in good standing.

Beyond what the state demands, the jobs themselves will ask for their own coverage. General contractors, project owners, and lenders routinely require proof of general liability and workers’ compensation before they let you on site, so treat the state’s requirement as the floor and the jobsite’s requirement as the reality.

Setting up your contracting business

Because the Secretary of State licenses a registered business, the smoothest applications start with the business already built. Handle the entity, the tax registrations, and the workers coverage first, and the license application simply confirms details that already exist.

Register the entity and match the name

Form your company through the North Dakota Secretary of State, whether that is a sole proprietorship using a registered trade name, a partnership with a fictitious partnership name, or a corporation or limited liability company. The name on your business registration, your liability insurance certificate, and your license application all have to match, so lock the structure before you print a single form.

Set up Workforce Safety and Insurance and taxes

If you hire, open a Workforce Safety and Insurance account and keep it current, because renewal each year requires you to certify that your payroll taxes, Workforce Safety and Insurance premiums, and unemployment insurance premiums are paid. Register for the state tax accounts your work triggers as well. Getting these accounts opened before your first payroll keeps you clean from your first invoice and makes the annual renewal a formality.

Keep your good standing intact

The registrar can classify your license as not in good standing if you let your liability insurance lapse, fail to keep a required trade name or fictitious name current, or let your corporation or limited liability company registration go inactive. A contractor told the license is not in good standing has to stop soliciting or entering new contract projects until the gap is fixed, so keep every registration live.

Renewing your North Dakota contractor license by March 1

A North Dakota contractor license is not a one-time purchase, and the calendar is strict. It runs on a contractor year that ends every March 1, and you renew on or before that date. The renewal fee follows your class: $30 for Class D, $45 for Class C, $60 for Class B, and $90 for Class A.

Renewal is a little more involved than paying a fee. Through the FirstStop portal you list each project, contract, or subcontract you completed in North Dakota during the prior calendar year that exceeded $50,000, along with the nature of the work. You file a fresh certificate of liability insurance naming the registrar, and you certify that your payroll taxes, Workforce Safety and Insurance premiums, and unemployment insurance premiums are paid. The registrar forwards your project list to the state tax commissioner, so the numbers need to be accurate.

Miss the March 1 deadline and your license is treated as not in good standing, which under the statute means you are considered unlicensed. There is a grace window: within sixty days after March 1 the registrar mails you notice, and you then have until June 1 to renew by paying a $50 penalty fee on top of the renewal fee and filing the renewal application. After June 1, a license that has not been renewed is expired, and you are back to applying fresh.

Penalties for unlicensed work in North Dakota

North Dakota takes unlicensed contracting seriously, and the consequences reach past a fine. Acting in the capacity of a contractor on a job over $4,000 without a license is a class A misdemeanor. On top of any criminal exposure, the registrar can assess a civil penalty of up to three times the license fee for your class, and that penalty has to be paid before a license will be issued.

The quieter penalty is often the costliest. Without a license, you cannot maintain any claim, action, suit, or proceeding in a North Dakota court that relates to your work as a contractor. In plain terms, if a client refuses to pay, an unlicensed contractor cannot sue to collect. You can do the work and still have no legal path to the money.

The law goes further for contractors who take payment and then deceive or abandon. North Dakota defines construction fraud to include using deception to get paid, taking money for materials and willfully failing to pay the supplier, and willfully abandoning a project after being paid. The grade of the offense scales with the money involved.

None of this is exotic. It is the everyday reason to get licensed before you take a deposit: a $100 Class D license is trivial next to a job you cannot legally collect on, or a felony grade tied to the size of a payment you mishandled.

North Dakota contractor license costs, itemized

The headline number is small, and it is the class fee. North Dakota does not stack a separate application fee, license fee, and exam fee the way many states do. Your class fee covers issuance, full stop. Here is the full picture, including the third-party costs that are easy to forget.

The state’s own charge, then, is as low as $100 for a Class D license and tops out at $450 for Class A, with no bond premium to add because North Dakota dropped that requirement. Set against the rest of the country, that is a bargain on the low end and mid-pack at the top. Among the states that license general contractors at the state level, the median first-year cost is about $176, so a Class D license sits below the middle while a Class A license runs above it. The national spread is wide: the cheapest statewide credential runs about $25 in Nebraska, and the most expensive climbs to roughly $900 in Nevada. North Dakota also lands in the minority of states that charge for a license but require no competency exam, which keeps both the cost and the timeline down.

Local rules across North Dakota

The North Dakota contractor license is a statewide credential. Earn it once through the Secretary of State and it is recognized in every county. What it does not do is replace the local building permits each city requires before you break ground. On most jobs you clear two layers: the state license and the city building department.

State law ties the two together. When you apply for a building permit, you have to give the permit-issuing official your contractor license number, which that official writes onto the permit before the work is inspected. Even a property owner doing exempt work on their own place has to supply the license number of each subcontractor doing permitted work. So in cities like Fargo, Bismarck, Grand Forks, and Minot, expect the building department to ask for your state license number as part of pulling the permit, and expect inspections on top of it.

Public work adds a wrinkle. For most public contract projects, your bid has to include a copy of your current license, and you must have held the license in the right class at least ten days before the bid date to be a qualified bidder. A bid that arrives without the license enclosed can be returned unread. Bids to the Department of Transportation, the Public Service Commission, and federal-aid highway work are the exceptions to that rule.

North Dakota sits between two states with very different systems, and contractors who work across the border need both credentials. Its neighbor to the east runs a state-level program covered in our Minnesota contractor license guide, and to the southeast the rules differ again in our Wisconsin contractor license guide. If you bid jobs in more than one state, read each state’s own guide rather than assuming North Dakota’s thresholds travel.

Common pitfalls to avoid

Most trouble with a license in North Dakota is self-inflicted and easy to sidestep once you know where contractors slip.

• Assuming small jobs are exempt when they add up. The trigger is the cost, value, or price of the job, and it is only $4,000. Many everyday projects clear that line, so do not treat the license as something only big builders need.
• Licensing in the wrong class. Your class caps the single-contract value you can build. Take a $400,000 job on a Class C license, which caps at $300,000, and you are working outside your class.
• Letting insurance lapse. An expired liability policy is a fast way to lose good standing, and a license not in good standing means you must stop taking new work until it is fixed.
• Missing the March 1 renewal. Blow the deadline and you are treated as unlicensed. You can still recover through June 1 by paying the $50 penalty, but after that the license is expired.
• Forgetting the trade credential. The contractor license does not cover electrical, plumbing, or asbestos abatement work. Those come from their own boards, and skipping them is its own violation.
• Bidding public work too late. You must hold the license at least ten days before a public bid date and enclose a copy with the bid, or it can be returned unread.

Bottom line

A North Dakota contractor license is one of the simpler and cheaper statewide credentials in the country. Once a job’s cost, value, or price tops $4,000, you need it. Register your business with the Secretary of State, pick the class that fits your biggest single contract, file a certificate of liability insurance and your Workforce Safety and Insurance proof, and sign your statement of experience, because there is no exam to pass. The class fee covers issuance, from $100 for Class D up to $450 for Class A, with no bond to buy. Renew every year by March 1 for $30 to $90, keep your insurance active, and pull your local building permits, and you hold a license that works statewide.
