North Dakota Contractor Licensing Guide: How to Get Licensed by Trade
In North Dakota, contractors must register with the Secretary of State—not obtain a traditional occupational license—but requirements vary significantly by trade. Unlike many states, ND does not require a statewide contractor examination; however, specific trades like electrical, plumbing, and HVAC are regulated separately by their respective boards. All contractors performing work over $2,000 must register annually (now biennially as of 2023) and meet bonding and insurance mandates.
Registration vs. Licensing: Understanding ND’s System
North Dakota does not issue occupational contractor 'licenses' through a central licensing board. Instead, the Secretary of State administers mandatory contractor registration for any individual or business performing construction services valued at $2,000 or more per project. This is a registration requirement—not a competency-based license—meaning no trade exam, pre-qualifying education, or apprenticeship hours are mandated by the SOS. However, certain trades operate under separate regulatory authorities: the North Dakota Electrical Board oversees electricians, the Plumbing Board regulates plumbers, and the HVACR Board governs heating, ventilation, air conditioning, and refrigeration professionals. These boards do require examinations, continuing education, and trade-specific licenses. General contractors, handymen, and remodelers fall solely under SOS registration unless they perform regulated sub-trade work. Registration is valid for two years (renewed biennially), costs $100, and must be completed online via the SOS website before bidding or starting work. Failure to register may result in civil penalties up to $1,000 per violation and loss of lien rights. Contractors must also display their registration number on all advertising, contracts, and vehicles.
Trade-Specific Categories & Regulatory Authorities
While the SOS handles broad contractor registration, North Dakota enforces strict trade-specific oversight for high-risk disciplines. Electricians must hold a license from the North Dakota Electrical Board—requiring either 8,000 hours of supervised experience plus passing the journeyman exam, or completion of an approved apprenticeship program. Plumbers must be licensed by the North Dakota Plumbing Board after 4,000–8,000 hours of experience and successful completion of both written and practical exams. HVACR technicians must obtain licensure from the HVACR Board, which mandates 4,000 hours of field experience and passage of the state exam. In contrast, residential builders, roofers, painters, drywall installers, and flooring contractors only need SOS registration—no trade exam or board approval. However, local municipalities (e.g., Fargo, Bismarck, Grand Forks) may impose additional permit requirements, zoning compliance, or local registration. Contractors should verify municipal ordinances before commencing work. Also note: specialty contractors such as well drillers, septic system installers, and manufactured home installers answer to distinct agencies—the Public Service Commission and Department of Environmental Quality—each with unique certification processes and fees.
Bonding, Insurance, and Financial Requirements
All registered contractors in North Dakota must maintain a minimum $10,000 surety bond filed with the Secretary of State. The bond protects clients against financial loss due to incomplete work, defective craftsmanship, or failure to comply with contractual obligations. It is not insurance for the contractor but a legally enforceable guarantee payable to harmed parties. Bond providers must be licensed in ND and listed with the U.S. Treasury; self-bonding is not permitted. In addition, contractors must carry general liability insurance with minimum limits of $100,000 per occurrence and $300,000 aggregate—or provide a signed affidavit stating they are exempt due to being a sole proprietor with no employees and performing only residential work under $25,000 (though this exemption carries significant risk and is rarely advised). Workers’ compensation insurance is mandatory for any contractor with one or more employees, administered through the North Dakota Workforce Safety & Insurance (WSI) agency—private carriers are prohibited. Proof of both bond and insurance must be uploaded during SOS registration and renewed with each biennial filing. Failure to maintain active coverage results in automatic registration suspension and potential fines.
Application Process, Renewal, and Compliance Tips
To register, contractors must complete the SOS Form SOS-CON-REG online via the North Dakota Business Registration Portal. Required documents include a completed application, $100 fee, $10,000 surety bond certificate, proof of liability insurance (or affidavit), and identification (e.g., driver’s license or EIN confirmation). Sole proprietors use their SSN; LLCs and corporations must have an active ND entity filing. Processing is typically immediate upon submission and payment. Renewal occurs every two years on the anniversary date of initial registration—SOS sends email reminders 60 days prior. Late renewals incur a $25 penalty and lapse coverage, halting legal ability to contract. Best practices include: (1) verifying trade-specific board requirements before registering (e.g., an electrician must hold both an Electrical Board license AND SOS registration); (2) keeping bond and insurance policies active beyond renewal dates to avoid gaps; (3) updating SOS within 30 days of address, ownership, or business name changes; and (4) retaining records for five years per ND Century Code § 43-07-09. Noncompliance may trigger investigations by the Attorney General’s Office and jeopardize contract enforceability in court.

Do I need a contractor license in North Dakota if I only do small residential repairs?
Yes—if the total value of labor and materials exceeds $2,000 per project, you must register with the ND Secretary of State. There is no 'handyman exemption' in state law. Even sole proprietors performing painting, drywall, or flooring jobs over $2,000 must register, post bond, and carry liability insurance.
Can I use my Minnesota contractor license to work in North Dakota?
No—North Dakota does not offer reciprocity with any other state. You must register separately with the ND Secretary of State and, if performing regulated trades (e.g., electrical), obtain a distinct ND license from the relevant board. Out-of-state entities must also appoint a registered ND agent.
What happens if my SOS registration expires and I keep working?
You lose legal standing to enforce contracts, file liens, or collect payment through civil court. The ND Attorney General may impose fines up to $1,000 per unregistered project, and clients may report violations to the SOS. Re-registration requires paying the $100 fee plus a $25 late penalty—and you cannot backdate coverage.
