Can a General Contractor Do Electrical or Plumbing Work in North Dakota?

A General Contractor License Doesn't Cover Electrical or Plumbing

This is one of the most common misunderstandings in North Dakota construction. A state-issued general contractor license — whether Class A, B, C, or D — does not authorize you to perform electrical, plumbing, or regulated mechanical work. Electrical and plumbing are governed by separate state boards; mechanical/HVAC work follows a combination of State Plumbing Board rules and local municipal licensing and exams.

A general contractor holding a Class A unlimited license can bid on a $5 million commercial project, but they still can't wire a single outlet or connect a drain line themselves. They must subcontract that work to properly licensed trade specialists.

The general contractor license does not authorize that work, so use properly licensed trade specialists for electrical, plumbing, and regulated mechanical work.

The State Electrical Board

The North Dakota State Electrical Board (NDSEB) has exclusive authority over all electrical installations in the state. General contractors cannot self-perform electrical work regardless of their experience or the project's simplicity.

To perform electrical contracting work in North Dakota, a business must designate a licensed Master Electrician as its responsible qualifier — the person who takes professional responsibility for the quality and code compliance of all electrical work performed under that license.

Key requirements for electrical contracting:

• Master Electrician license from the NDSEB (requires passing a state exam)
• $10,000 surety bond filed directly with the NDSEB
• Licensed Class B electricians can only perform limited residential or farmstead work in municipalities under 2,500 population
• State inspection fees apply to all electrical work (starting at $50 for projects under $500, scaling up with project value)

The NDSEB operates independently from the Secretary of State's contractor licensing system. You could hold both a general contractor license and an electrical contractor license, but they're separate credentials from separate agencies with separate renewal cycles.

The State Plumbing Board

Plumbing work falls under the North Dakota State Plumbing Board (NDSPB), which administers its own licensing and examination system entirely separate from both the Secretary of State and the Electrical Board.

To perform plumbing contracting in North Dakota, you need:

• Master Plumber license from the NDSPB (requires passing a state-administered written exam)
• Initial licensing costs — $35 exam fee plus $165 licensing fee ($200 total)
• Local registration — state-licensed master plumbers must still register with local building divisions (Fargo, Grand Forks, etc.) and pay local registration fees before pulling municipal plumbing permits

The plumbing board also has jurisdiction over certain aspects of hydronic heating systems and gas piping connections, which creates overlap with mechanical/HVAC work. If your project involves a gas-fired furnace or boiler installation, the plumber-vs-HVAC licensing question gets complicated depending on whether the work involves fuel gas piping (Plumbing Board jurisdiction) or air distribution (municipal mechanical licensing).

Mechanical and HVAC — The Municipal Layer

Here's where it gets genuinely confusing. North Dakota doesn't issue a unified state-level HVAC license. Instead, mechanical compliance is managed through a hybrid of State Plumbing Board rules and local municipal licensing.

The Plumbing Board controls hydronic heating and gas piping. Municipal building departments control forced-air HVAC. Major cities proctor their own mechanical exams:

Fargo proctors the State of North Dakota Reciprocity Exams for Master and Journeyman HVAC licenses. As of January 2026, these exams are based on the 2024 International Mechanical Code and International Fuel Gas Code. A passing score carries reciprocity across participating North Dakota municipalities — but you still need to buy a local mechanical license from each city where you work.

Bismarck runs its own mechanical installer exams based on the 2021 International Mechanical Code. Journeyman candidates need 6,000 hours of documented practical experience; Master candidates need 10,000 total hours including 6,000 at the journeyman level.

For a general contractor, the practical rule is straightforward: subcontract all electrical, plumbing, and HVAC work to properly licensed specialists. Your role is coordinating the project, managing the schedule, and ensuring the subs carry the correct credentials.

What a General Contractor Can Do

To be clear about what your state general contractor license covers, subject to local permits and requirements: construction, repair, alteration, dismantling, or demolition work that doesn't fall under a regulated trade board. That includes:

• Framing and structural carpentry
• Concrete and masonry
• Roofing and siding
• Drywall and finish work
• Painting and flooring
• Demolition
• Site preparation and grading
• General project management and coordination

Your state license class determines your per-project dollar cap (Class D: $100,000, Class C: $300,000, Class B: $500,000, Class A: unlimited). Within that cap and outside the regulated trades, you're authorized to self-perform or subcontract as you see fit.
