Who needs a North Dakota contractor license?
North Dakota requires a state contractor license when the cost, value or price of one job exceeds $4,000. The Secretary of State says the rule includes subcontractors, general contractors, public contractors and nonresident contractors. See the current contractor page.
The license class is based on the amount of a single job, not annual revenue. The same application also requires liability-insurance documentation and the applicable Workforce Safety and Insurance record. Electrical, plumbing and other specialized work can require separate credentials outside this Secretary of State license.
For a clean filing, settle four questions before opening FirstStop: Is the business registered under the exact name you will use? What is the largest job you expect to perform? Which WSI document applies? Does the scope trigger another board's license or a local permit?
North Dakota contractor license classes
The current table lists Class A at over $500,000 per job with a $450 fee, Class B up to $500,000 with $300, Class C up to $300,000 with $225, and Class D up to $100,000 with $100. The table appears on the state contractor page.
| Class | Contract amount per job | Initial fee |
|---|---|---|
| A | Over $500,000 | $450 |
| B | Up to $500,000 | $300 |
| C | Up to $300,000 | $225 |
| D | Up to $100,000 | $100 |
Choose against the total contract amount you may accept on one job. A Class C fits a $275,000 job, but not a $325,000 job. That larger job moves into Class B. Do not choose from current backlog or annual sales; the state table repeatedly describes the limit as “per job.”
Leave realistic room for alternates and change orders. The fee difference can be smaller than the cost of discovering that the signed contract no longer fits the class.
Liability insurance and WSI documents
The application must include a liability-insurance certificate in the same name requested for the contractor license, with the North Dakota Secretary of State at its published Bismarck address as certificate holder. Read the certificate instructions.
The WSI attachment depends on the workforce. The Secretary of State requires a current WSI certificate of payment when the applicant has employees residing in North Dakota; when the applicant has no employees residing in North Dakota and does not meet the significant-contact tests, it requires a WSI letter of good standing. The state page describes both paths.
Ask the insurer to issue the certificate in the exact legal or registered trade name used on the application. Our guide to general liability insurance for contractors explains the coverage conversation, but the Secretary of State's filing instructions control the certificate holder and naming details.
How to apply through FirstStop
Use this order:
- Resolve business registration. A sole proprietor or general partnership may need a trade or fictitious partnership name; corporations, LLCs and other listed structures must register before the contractor filing.
- Use the exact registered name. The Secretary of State says a registered business must use the same name on the contractor application.
- Select the class. Base it on the highest expected contract amount per job.
- Collect the insurance and WSI documents. Check names and dates before upload.
- Prepare the qualifications statement. The application requires a signed statement of contracting experience and qualifications.
- Submit through FirstStop. Pay the initial class fee and retain the filing record.
- Check separate trade and local requirements. Do this before promising that the state contractor license covers the entire scope.
The state instructs applicants to submit the Contractor License Application through the FirstStop Portal and says the application requires a signed experience-and-qualifications statement. See Step 2 on the contractor page. If schedule is tight, build document collection into the lead time described in how long contractor licensing can take.
How class limits affect bids and change orders
Use the class ceiling as a contract-control field, not just an application answer.
Worked example: A contractor expects a base contract of $285,000 with a likely $35,000 owner option. Class C stops at $300,000 per job, while Class B covers jobs up to $500,000. If the option is accepted, the total becomes $320,000, so Class C does not fit the expected contract. Class B does.
The current initial fees are $450 for Class A, $300 for Class B, $225 for Class C and $100 for Class D. Renewal fees are $90, $60, $45 and $30 respectively. Both fee tables are on the Secretary of State page.
Put the license class and ceiling in bid review. Check it again before executing a change order that materially increases the contract. For broader budgeting, contractor license cost covers insurance, bonding and administrative costs that can matter more than the filing fee.
Electrical work requires separate licensing
A Secretary of State contractor license is not an electrical license. The Secretary of State names licenses issued by the North Dakota State Electrical Board as specialized credentials outside its contractor license. See the state's separate-license warning.
The Electrical Board says a person or business that undertakes or offers to plan, supervise, install, alter or repair wiring or equipment for electric light, heat or power must apply to the Board, and the Board examines applicants for the license class sought. Read the Board's licensing overview.
That is the boundary an operator needs: the contractor class controls the general contracting registration and job-value ceiling; the Electrical Board controls electrical licensure. Use the North Dakota electrician license guide for the trade tiers, but check the Board's current application and local inspection requirements for the actual job.
Plumbing uses a separate state board
Plumbing is separate too. The Secretary of State lists licenses issued by the North Dakota State Plumbing Board as specialized credentials that are not part of the contractor license. See Step 3 on the contractor page.
The Plumbing Board's current site provides separate functions to apply for plumbing, sewer-and-water or water-conditioning licenses, schedule licensing exams, look up licensees and renew credentials. Use the Board's licensing site.
Do not read a Class A contractor license as permission for unlicensed employees to self-perform regulated plumbing. Assign the plumbing scope to properly credentialed people, check permits and inspections, and carry those trade requirements in the subcontractor prequalification file.
Nonresidents, renewal and project reporting
North Dakota contractor licenses renew on or before March 1 each year through FirstStop. The renewal requires a list of each North Dakota project, contract or subcontract completed in the prior calendar year that exceeded $50,000, certification that payroll taxes and specified insurance premiums are paid, and a liability-insurance certificate. Review the renewal checklist.
The state says filings received after the deadline incur a late fee. Current renewal fees are:
| Class | Renewal fee |
|---|---|
| A | $90 |
| B | $60 |
| C | $45 |
| D | $30 |
The contractor page includes nonresident contractors in the same more-than-$4,000 licensing rule. That is not trade-license reciprocity. An out-of-state company still needs to resolve its North Dakota business registration, contractor filing, WSI path and any separate electrical or plumbing credentials.
Run a report of jobs over $50,000 before renewal season. Waiting until the filing is open to reconstruct a year of contract values is avoidable work.
Frequently asked questions
Does a $4,000 job require a North Dakota contractor license?
The Secretary of State says the requirement applies when the job exceeds $4,000. The published threshold does not say “$4,000 or more.”
Which contractor class covers a $400,000 job?
Class B covers jobs up to $500,000. Class C stops at $300,000 per job.
What insurance document goes with the application?
A certificate of liability insurance in the same name requested for the license, naming the North Dakota Secretary of State at its published address as certificate holder.
When is renewal due?
On or before March 1 each year. Renewal includes insurance, certifications and a report of completed North Dakota projects over $50,000 from the prior calendar year.
Does the contractor license include electrical and plumbing work?
No. The Secretary of State identifies Electrical Board and Plumbing Board licenses as separate specialized credentials.
A practical threshold note
The $4,000 trigger is based on one job's cost, value or price. Keep a license check in estimating even for repair and subcontract work, because a small scope can cross the line once labor, materials and accepted changes are counted.
For class selection, keep two numbers in the file: the executed contract and the maximum reasonably expected amount after known options. If the second number crosses the current class ceiling, solve that before signing rather than treating it as a renewal problem.
