Minnesota trade license reciprocity

Minnesota issues a statewide Class A Journeyworker Electrician license through the Department of Labor and Industry (DLI); there is no municipal electrician licensing. A new applicant documents at least 48 months of qualifying experience (Minn. Stat. 326B.33, subd. 2 and Minn. R. 3800.3520), pays the $50 application and examination fee, and passes the DLI-administered written exam. Under Minn. Stat. 326B.33, subd. 20 the commissioner, with Board of Electricity approval, has reciprocity agreements with nine states whose journeyworker licensees are licensed without the Minnesota exam. Licenses expire every two years and renewal requires 16 hours of continuing education, 12 of them on the NEC.

Minnesota issues a statewide, person-held Class A Master Electrician license through DLI; the separate electrical contractor license is a business license that must employ a master, and is not covered here. A new master applicant qualifies under Minn. Stat. 326B.33, subd. 1 with a four-year electrical engineering degree, one year of experience as a licensed journeyworker, or five years of experience planning, laying out, supervising and installing electrical systems (60 months under Minn. R. 3800.3520), pays the $50 application and examination fee, and passes the DLI-administered written exam. Reciprocity agreements under subd. 20 waive the exam for master electricians from Iowa, Nebraska, North Dakota and South Dakota. Master licenses expire on the last day of February of each odd-numbered year and renewal requires 16 hours of continuing education, 12 of them on the NEC.

Minnesota has no state HVAC or refrigeration technician license at any level. The Department of Labor and Industry (DLI) states that there is 'no state license requirement for individual employees of mechanical contractors' and no state license for mechanical contractors either; the only statewide requirement is the $25,000 mechanical contractor bond that a business must file with DLI under Minn. Stat. 326B.197 before contracting for gas, heating, ventilation, cooling, air conditioning, fuel burning or refrigeration work. Journeyman-level licensing exists only where a city requires it: Minneapolis and Saint Paul both require a journeyman Certificate of Competency (Warm Air/Ventilation or Refrigeration) to work in the trade, issued after four years of experience and an exam, and Saint Paul additionally registers trade workers; Bloomington, Rochester and Duluth license contractors or master installers but not journeymen. An out-of-state journeyman HVAC license has no state-level recognition in Minnesota and none of these cities publish a path that accepts it; the only local reciprocity is between Minneapolis and Saint Paul. Anyone who handles refrigerants must also hold federal EPA Section 608 certification, which is not a state license.

Minnesota issues no master HVAC, master refrigeration or HVAC contractor license. The only statewide requirement is the $25,000 mechanical contractor bond that a business files with the Department of Labor and Industry (DLI) under Minn. Stat. 326B.197 ($100 filing fee, valid two years) before contracting for gas, heating, ventilation, cooling, air conditioning, fuel burning or refrigeration work; DLI states that there is no state license for mechanical contractors or their employees and that cities may require licensure or a competency card. The master-level credential therefore exists only at the city level: Minneapolis issues Master Warm Air Ventilation and Master Refrigeration Certificates of Competency (four years of experience and education plus an ICC exam) and requires a master card holder behind each HVAC Class A or Refrigeration Systems Installer contractor license; Saint Paul issues Master Warm Air, Ventilation and Refrigeration competency cards and requires one for each Warm Air/Ventilation business trade license; Rochester licenses individual HVAC Master Installers after a city certificate of competency; Bloomington licenses mechanical contractors on a Minneapolis or Saint Paul card or its own test. An out-of-state master HVAC or mechanical contractor license has no state-level recognition and none of these cities publish a path that accepts it; Minneapolis and Saint Paul recognize each other's master cards. Federal EPA Section 608 certification is separately required of anyone handling refrigerants.

Minnesota issues a statewide Journeyworker Plumber license through the Department of Labor and Industry (DLI); DLI's license-types page states the license 'authorizes the individual to work statewide', and no city-issued plumber licenses appear on DLI's pages (DLI also issues a Restricted Journeyworker license limited to towns under 5,000). A new applicant must first pass DLI's written journeyworker exam ($50 exam fee), and is eligible to sit it after a registered apprenticeship, four years (1,750 hours per year, 7,000 hours) of practical experience as a DLI-registered unlicensed plumber (Minn. Stat. 326B.47, subd. 2), two years under a Minnesota restricted license, or by holding a current plumber's license from another state that requires at least four years of experience and an exam. Journeyworker plumbers licensed by examination in North Dakota or South Dakota may be licensed without the Minnesota exam under DLI's reciprocity page. Licenses expire December 31 of odd-numbered years; renewal is $53 and requires 16 hours of continuing education, at least eight on the State Plumbing Code (2020 Minnesota Plumbing Code, Minn. R. ch. 4714).

Minnesota issues a statewide, person-held Master Plumber license through DLI; the license 'authorizes the individual to perform plumbing statewide', and a separate Plumbing Contractor license (a business license that must have a licensed master plumber as its responsible individual and carry a bond, general liability and workers' compensation insurance under Minn. Stat. 326B.46) is not covered here. DLI also issues a Restricted Master Plumber license limited to cities and towns under 5,000. A new master applicant must pass DLI's written master plumber exam ($50 exam fee) and is eligible to sit it after at least one year of practical experience as a licensed journeyworker plumber, with a current master plumber license from another state whose requirements DLI determines are equivalent to Minnesota's, or with a Minnesota restricted master license plus five years in business as a plumbing contractor. Master plumbers licensed by examination in North Dakota or South Dakota may be licensed without the Minnesota exam. Master licenses expire December 31 of even-numbered years (Minn. Stat. 326B.49); renewal is $93 and requires 16 hours of continuing education, at least eight on the State Plumbing Code.

Minnesota licenses homebuilders statewide through the Department of Labor and Industry, which issues a Residential Building Contractor (BC) license for new construction and remodeling, a Residential Remodeler (CR) license for work on existing structures only, and a narrower Residential Roofer (RR) license for roofing alone. The license is required of anyone who contracts directly with the owner of residential real estate, meaning a building constructed for habitation by one to four families including detached garages, to provide work in more than one of eight statutory special skills, and of an owner who builds or improves homes for resale or speculation. It is the business that holds the license, not the person: every company designates a qualifying person who must be an owner, officer, member, general partner, chief manager or managing employee, and that individual personally passes DLI's written exam and carries the resulting QB or QC registration number, which the company's license depends on. Minnesota attaches no experience, apprenticeship or education prerequisite to that exam. In place of a surety bond, licensees pay into the Contractor Recovery Fund, which repays homeowners who win a judgment against a licensed contractor, and they must carry commercial general liability and workers' compensation insurance and keep an active Minnesota Secretary of State filing. Cities and counties may not require a separate local license for work that the state license covers.

Minnesota does not license general, commercial or unlimited building contractors at the state level. The Department of Labor and Industry's contractor licensing chapter reaches only residential contractors, remodelers, roofers and manufactured home installers, and the residential license stops at buildings built for one to four families. What a commercial builder needs instead is a Construction Contractor Registration: state law requires any business providing public or private commercial or residential building construction or improvement services in Minnesota to register with DLI first, and DLI's own guidance puts it simply, that commercial work falls under contractor registration if you do not hold a residential license. Registration is a filing rather than a qualification. There is no exam, no qualifying person and no experience or education test; the legislature created the program mainly to help DLI investigate worker misclassification. A business that already holds a DLI license or certificate, an employee of a registered contractor, an architect or professional engineer, a school district and a volunteer builder are all exempt. Trade work inside a commercial building is still licensed separately, so the electrical, plumbing, high-pressure piping, elevator and boiler scopes go to contractors holding those DLI licenses.

Minnesota issues no statewide home inspector license, so there is no state credential to apply for, no state examination and nothing to transfer from another state, and a buyer's home inspection can be performed anywhere in Minnesota by anyone. Chapter 326B of the statutes carries every construction credential the Department of Labor and Industry issues — the state building code and its building officials and construction code inspectors, elevators, electrical, plumbing, water conditioning, high pressure piping, boilers, contractor registration, and the residential trades licenses for residential building contractors, remodelers, roofers and manufactured home installers — and no section of it creates a home inspector license; a 2006 bill that would have added one was not enacted. Where a credential does exist it is issued by a city, not by the state: Minneapolis, Saint Paul and Bloomington each require a pre-sale evaluation of the home before it can be marketed, and each will accept that evaluation only from an evaluator it has licensed itself. Saint Paul's license is the demanding one and it is the one place in Minnesota where the National Home Inspector Examination counts: an applicant must already hold a passed NHIE before being admitted to the city's own written test, then pass a practical evaluation of a test house, carry insurance and pay an annual license fee. What binds an inspector doing ordinary unlicensed work is general law: the Prevention of Consumer Fraud Act makes unlawful any fraud, unfair or unconscionable practice, false promise, misrepresentation or deceptive practice in connection with the sale of merchandise, which the statute defines to include services, and Minn. Stat. section 8.31, subdivision 3a lets an injured person sue for damages, costs, investigation costs, reasonable attorney's fees and equitable relief. Beyond that it is the written pre-inspection agreement and ordinary contract and negligence law that set the duty owed, because Minnesota has enacted no statutory standard of care for home inspectors and no statute governing the content or form of a private inspection report. Two adjacent credentials matter in practice. Radon is licensed: since January 1, 2019 the Minnesota Radon Licensing Act has required an annual license from the commissioner of health for anyone who tests for radon for compensation, as a measurement professional, and separately for mitigation professionals, mitigation companies and analysis laboratories, so an inspector cannot add a radon test to the job without one. And any repair, remodeling or roofing work that comes out of a report belongs to a licensed residential building contractor, remodeler or roofer under chapter 326B, or to the state's licensed electrical, plumbing, mechanical and high pressure piping trades.
