North Dakota Contractor & Trade License Requirements
North Dakota requires a statewide contractor license through the Secretary of State for any construction project exceeding $4,000. Electricians and plumbers must also obtain separate trade licenses from the State Electrical Board and State Plumbing Board, respectively. HVAC and roofing contractors need only the general contractor license from the Secretary of State. Licenses are tiered by project value into four classes (A through D).
