Contractor licensing thresholds, regulator routing, requirements, reciprocity, and license types for North Dakota’s registration-based construction regulation model.
North Dakota uses a registration model through the Secretary of State for general construction exceeding $4,000 per project, with separate licensing boards for electrical and plumbing trades. The low dollar threshold and class-based registration tiers mean that nearly all construction activity in the state requires state-level credentials.
Always verify statutes, fees, and application details with the live regulator before making bidding, licensing, or legal decisions.
The fastest way to orient yourself in North Dakota is to know the registration threshold, the class system that caps per-job value, and the separate gates for electrical and plumbing work.

Contractors
Regulators
How do I register as a contractor in North Dakota?
Register with the Secretary of State for any construction project of $4,000 or more. Choose the registration class that matches your per-job value: Class D (up to $100,000), Class C (up to $300,000), Class B (up to $500,000), or Class A (over $500,000). You need proof of Workforce Safety and Insurance coverage and a liability insurance certificate. Average processing is 10 days. See Requirements.
What types of construction projects over $4,000 require registration?
All construction projects — commercial, residential, and public — exceeding $4,000 require contractor registration. This is one of the lowest thresholds in the country. Electrical and plumbing work also require separate state licenses regardless of dollar value. See Construction work regulated.
Does North Dakota require separate licensing for electrical or plumbing work?
Yes. Electrical work requires a license from the State Electrical Board, and plumbing, water conditioning, and sewer/water work require licenses from the State Plumbing Board. These are separate from general contractor registration and apply regardless of contract value. See Construction work regulated.
Where do I go to get registered or licensed?
North Dakota has three agencies: the Secretary of State for general contractor registration, the State Electrical Board for electrical licensing, and the State Plumbing Board for plumbing, water conditioning, and sewer/water licensing. See Who regulates construction.
How much does it cost to register or get licensed?
General registration ranges from $100 (Class D) to $450 (Class A) with annual renewals of $30 to $90. Electrical journeyman exam and renewal are each $25; master is $50. Plumbing journeyman application is $50 with $100 annual fee; master is $50 with $200 annual fee. See Requirements.
Can I use my out-of-state electrical or plumbing license?
Possibly. Electrical reciprocity covers Minnesota, Montana, and South Dakota for both master and journeyman. Plumbing reciprocity covers Minnesota and South Dakota (master and journeyman) and Montana (journeyman only). General contractor registration has no reciprocity. See Reciprocal agreements.
Are public improvement bonds required in North Dakota?
Yes. Public improvement contracts exceeding $200,000 require a bond in an amount equal to the contract price. Special municipal improvements may be exempt. See Construction work regulated.
What registration class do I need?
Class D covers projects up to $100,000 per job ($100 application, $30 renewal). Class C covers up to $300,000 ($225 / $45). Class B covers up to $500,000 ($300 / $60). Class A covers over $500,000 ($450 / $90). Choose the class that matches your largest anticipated single project. See Requirements.
Does North Dakota require licensing for residential construction?
Yes. Any residential construction project of $4,000 or more requires contractor registration with the Secretary of State. Plumbing and electrical work on residential projects also require separate state licenses. See Construction work regulated.
What experience is required for an electrical journeyman license?
Journeyman electricians need 8,000 hours of experience plus 576 hours of approved related training, or two years of approved technical/trade school. The trade exam requires a minimum score of 70%. Master electricians need one year as a licensed journeyman. See Requirements.
How does North Dakota's licensing model compare to other states?
North Dakota uses a three-body system: Secretary of State for general registration, plus independent boards for electrical and plumbing. The $4,000 registration threshold is one of the lowest in the country, capturing nearly all construction activity. This is more structured than minimal states like Kansas but less comprehensive than states with full trade licensing. See Construction work regulated.
How does the $4,000 threshold compare to other states?
The $4,000 threshold is notably low. Many states have no registration requirement at all, while others trigger licensing at $10,000 to $100,000. Combined with the class system that caps per-job value, North Dakota captures more construction activity under state oversight than most states. See Licensing thresholds.
What agencies handle electrical and plumbing licensing?
The State Electrical Board handles all electrical licensing independently from the Secretary of State. The State Plumbing Board handles plumbing, water conditioning, and sewer/water licensing. Each board has its own exams, fees, and reciprocity agreements. See Who regulates construction.
How does the registration class system work?
Registration classes control per-job value caps, not scope of work. Class D allows up to $100,000 per job, Class C up to $300,000, Class B up to $500,000, and Class A has no cap. Fees and renewal costs scale with class level. See Requirements.
What are the fees across trades?
Registration: $100-$450 application plus $30-$90 annual renewal by class. Electrical: $25 journeyman exam/renewal, $50 master exam/renewal. Plumbing journeyman: $50 application, $100 annual. Master plumber: $50 application, $200 annual. Water conditioning and sewer/water have additional fee structures. See Requirements.
What license classifications does North Dakota use?
General registration has four classes (A-D). Electrical offers Master (Contracting), Master (Non-Contracting), Journeyman, Apprentice, and Class B (Contracting). Plumbing covers Master, Journeyman, and Apprentice tiers for plumbing, water conditioning, and sewer/water. See Types of licenses.
How does reciprocity work in North Dakota?
Reciprocity exists only for electrical and plumbing — not for general contractor registration. Electrical reciprocity covers Minnesota, Montana, and South Dakota. Plumbing reciprocity covers Minnesota and South Dakota (master and journeyman) and Montana (journeyman only). See Reciprocal agreements.
What exam requirements exist?
Electrical journeyman exam requires 70% minimum. Plumbing journeyman exam requires 70% (based on 2018 ND Plumbing Code). Master plumber exam requires 80% minimum. Master electrician requires one year as a licensed journeyman. See Requirements.
What are the renewal cycles?
General contractor registration renews annually. Electrical licenses renew annually. Plumbing licenses renew annually. The Secretary of State processes registrations in about 10 days on average. See Requirements.
How does North Dakota compare to other Midwest states?
North Dakota’s low $4,000 threshold captures more activity than most Midwest states. The three-body structure (Secretary of State, Electrical Board, Plumbing Board) is moderately complex. It is more structured than Kansas or Missouri but simpler than Iowa’s DIAL model or Ohio’s five-agency system. See the Midwest region guide.

Contractors
Regulators
Start with project value to determine your registration class, then check whether the work also requires a separate electrical or plumbing license.
The general contractor registration threshold is $4,000 — one of the lowest in the country.
Registration classes cap per-job value: Class D at $100,000, Class C at $300,000, Class B at $500,000, Class A has no cap.
All electrical work requires a separate license from the State Electrical Board, regardless of contract value.
All plumbing work requires a separate license from the State Plumbing Board, regardless of contract value.
Public improvement contracts over $200,000 require a bond equal to the contract price.
Applicants must submit proof of Workforce Safety and Insurance coverage and a certificate of liability insurance.
North Dakota is best understood as a three-body system: Secretary of State for general registration, plus separate boards for electrical and plumbing.
General contractor registration is handled by the Secretary of State, not a dedicated contractor board.
Electrical and plumbing each have their own independent licensing boards with separate exams, fees, and reciprocity agreements.
Reciprocity exists only for electrical and plumbing — general contractor registration has no reciprocity.
The registration class system (A through D) controls project caps, not scope of work.
Four things you need to confirm before you can treat North Dakota as “ready” for a bid or an application. If any of these are unclear, you are not ready yet.
Classify the project lane
Identify whether the work is general construction, electrical, plumbing, water conditioning, or sewer and water. Multiple credentials may be required on the same project.
Determine the registration class
For general construction over $4,000, pick the class that matches your project value: Class D up to $100,000, Class C up to $300,000, Class B up to $500,000, or Class A for above $500,000.
Route to the correct regulator
General registration goes through the Secretary of State. Electrical and plumbing each have their own boards with separate applications.
Confirm the requirement set
Confirm exams, experience hours, fees, insurance (Workforce Safety and Insurance coverage plus liability), and bond requirements for public improvement contracts over $200,000.
If you can identify lane, registration class, regulator, and requirement set, you have the minimum package needed for a North Dakota readiness check.
North Dakota has one of the lowest general contractor thresholds in the country. Nearly all construction work requires state registration, and electrical and plumbing work requires separate state licensing on top.
