Who Needs a License in North Dakota?
If you want to install, maintain, or repair HVAC or mechanical systems in North Dakota, you need to comply with HVAC license requirements in North Dakota. In almost all cases, individual licensing is required for mechanical or HVAC work as defined in the state plumbing code. These licenses are controlled by the North Dakota State Plumbing Board and align with classifications for plumbers, sewer/water installers, or water conditioning specialists.
The law distinguishes between individual workers (who must be registered as apprentices, journeymen, or masters as appropriate) and business entities (who must register with the ND Secretary of State if they're bidding or contracting under a company or as a mechanical contractor). If you work as an employee under a licensed master plumber, you may not need your own business registration, but your supervisor still must meet the HVAC license requirements in North Dakota. For projects over specific size or value thresholds, both business and individual licenses are mandatory.
Below are practical scenarios where licensing is required:
Installing, modifying, or repairing any HVAC or mechanical system that falls under the scope of the ND plumbing code.
Pursuing mechanical contractor work as a business, particularly for large commercial or public projects.
Pursuing work as a sole proprietor, even if you work alone, if you pull permits or bid contracts personally.
Above all, always check your project's value and type, and verify licensing needs before advertising or bidding. For exemption or gray-area projects, contact the North Dakota State Plumbing Board directly.
HVAC License Types in North Dakota
North Dakota uses specific licensing classifications to regulate all HVAC/mechanical work. These are outlined below with the relevant scope of work for each license. HVAC license requirements in North Dakota can require multiple types, depending on your specialization and business structure.
Journeyman Plumber: This license allows you to perform HVAC and mechanical work under the supervision of a master plumber. You may not pull permits independently. The scope covers piping, installs, and repairs governed by the plumbing code.
Master Plumber: Masters can supervise job sites, pull permits, and are responsible for all mechanical/HVAC work performed by their crew. Most importantly, a master plumber can contract directly with clients and act as the qualifying party for business registrations. When licensed, you are also given journeyman status automatically, at no additional charge.
Sewer and Water Installer/Contractor: If you specialize in sewer or municipal water system work, this license is separate. Installers perform the work under supervision; contractors can supervise and contract this segment directly. (Separate application and examination apply.)
Water Conditioning Installer/Contractor: For those working only with water conditioning or treatment systems, these licenses offer a focused pathway. Requirements mirror those for other mechanical work but focus on specialized equipment and installation methods.
Mechanical Contractor (Business License): Any business entity (corporation, partnership, LLC, etc.) offering mechanical or HVAC contracting in North Dakota must register with the Secretary of State. This license type is always tied to a qualifying master plumber who is responsible for the technical quality and compliance of all work performed.
These licenses reflect both individual technical qualifications and business responsibilities. Always match your activities to the proper class as the board requires.
How to Get Licensed in North Dakota
The process for fulfilling HVAC license requirements in North Dakota follows these steps. Each step differs slightly by license class, so always use the official application forms for your category.
Review License Qualifications: Start by identifying which license type you need (e.g., journeyman, master, installer, contractor). Carefully check the plumbing board’s site and state code for prerequisites.
Complete Required Experience: Accumulate the hands-on work experience dictated by the board (e.g., practical hours under supervision), as outlined in the application or on the NDSPB website.
Submit Application with Documentation: Prepare application packages via forms from the ND eForms portal. Include proof of experience, relevant transcripts, and pay the initial exam or application fee (as detailed below). Some license classes have no first-time fee, but always verify current amounts.
Schedule and Pass Board Exam: Wait for the board to schedule your exam (given every other month). Take and pass the appropriate written and practical test for your license category.
Obtain Initial License: Upon passing, receive your NDSPB license certificate governing all HVAC/mechanical work in that category.
If a Business, Register with Secretary of State: If you operate as a contracting company, create your account on the SOS FirstStop portal, list your qualifying master plumber, and complete the business registration and fee process.
Renew Annually: All licenses are valid for one year and must be renewed before expiration. Complete renewal via the board’s online system or mail per the cycle in the sections below.
Each path may have additional required supporting materials, depending on classification or board criteria.
Application Requirements
Fulfilling HVAC license requirements in North Dakota means meeting the board’s rules for experience, age, supervision, and often insurance/bond standards. Requirements are enforced at the application and renewal stage.
Experience and Age
You must demonstrate relevant, supervised experience for each category:
Journeyman Plumber: Hands-on experience in mechanical or plumbing, tracked in hours as per the plumbing board process. Exact time frames for journeyman are not detailed in statute. Always check NDSPB’s license page.
Master Plumber: Must first be a journeyman and meet board experience requirements. If approved, you are granted both master and journeyman status for one fee.
Sewer & Water Installer: Two years (approximately 3,400 hours) under a qualified supervisor.
Sewer & Water Contractor: One year (about 1,700 hours) after installer license.
Water Conditioning Installer: One year (1,900 hours) documented apprenticeship.
Contractors: The business must have a qualifying master plumber on record and register with the Secretary of State. Additional bond/insurance details not provided; verify directly with the Secretary of State.
Bond and Insurance
The brief does not report official current bond or insurance minimums for individual or business HVAC license requirements in North Dakota. Contractors must verify these requirements with the Secretary of State and plumbing board when registering their business or renewing.
Background Check and Federal Certifications
No explicit background check or federal EPA certification requirement appears in the NDSPB’s application process as of 2026. For specialty work (such as refrigerant handling), verify directly with the board and applicable federal agencies.
Exams
Prospective license holders must pass a written and (where applicable) open book exam administered by the ND State Plumbing Board to satisfy HVAC license requirements in North Dakota. Exam structures and wait periods are rigid, so plan carefully.
Journeyman Plumber: Five-part exam, including two closed-book portions (100 multiple-choice questions and drain/waste vent sizing), and three open-book segments (40 completion, water pipe sizing, drain/waste/vent with fixtures). The entire test allots five hours. If you fail, you must wait six months to retake. Find more details at the board's exam page.
Master Plumber: Exam has four parts: one closed-book (100 multiple-choice) and three open-book segments. Same five-hour limit and six-month wait for retake as journeyman.
Sewer & Water Installer/Contractor: Each takes a two-part exam: closed-book (25 multiple-choice) and open-book (25 completion). If you do not pass, a three-month retake wait applies.
Water Conditioning Installer/Contractor: The board uses a similar two-part, five-hour structure and three-month retake gap for these licenses.
The board sets passing scores (not published in statute) and will notify you when you are eligible for testing. Exams occur every other month in standard locations. Secure your slot through application submittal and approval first.

Renewal Cycle and Lapse
Licenses renew annually. Plumbing apprentice, journeyman, and master licenses expire based on the individual registration cycle (details may be included on your license card or through the renewal instruction page). For Sewer & Water license holders, licenses are valid July 1 to June 30. If a license is not renewed for over one year past expiration, the plumbing board requires you to reapply and retake the appropriate examination.
Continuing Education
No explicit continuing education (CE) requirement is published for plumbing or HVAC license renewals in North Dakota as of 2026. That said, changes in code or adoption of national standards may introduce CE at the board’s discretion. Always verify the latest details before your cycle deadline. If you let your license lapse, you may be required to restart the exam and application process.
Reciprocity
The North Dakota State Plumbing Board extends reciprocity to out-of-state journeyman or master plumbers provided their home state’s requirements are substantially equivalent and there is a formal reciprocity agreement between states. The board may waive the exam for qualifying applicants. Reciprocity does not substitute for completing business registration or any other local code requirements in North Dakota.
Always submit documentation of your out-of-state credentials and confirm with the board if your license will be honored. Review reciprocity law specifics and download the application at the NDSPB licensing page.
