Minnesota trade license reciprocity
How Minnesota licenses each trade and level, who it reciprocates with, and where a Minnesota license goes.
Electricians
Minnesota journeyman electrician · “Class A Journeyworker Electrician”
Statewide license
Issued by Minnesota Department of Labor and Industry (DLI), Board of Electricity
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 master electrician · “Class A Master Electrician”
Statewide license
Issued by Minnesota Department of Labor and Industry (DLI), Board of Electricity
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.
HVAC Technicians
Minnesota journeyman HVAC technician
Licensed by cities and counties
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.
How local licensing works in Minnesota
How local licensing works. Minnesota licenses neither HVAC contractors nor HVAC workers at the state level. DLI's only role is the $25,000 mechanical contractor bond (Minn. Stat. 326B.197; $100 filing fee for two years), which the statute makes 'in lieu of all other bonds to any political subdivision'. Everything about who may personally do HVAC work comes from city ordinances, and most Minnesota cities require nothing of employees.
Minneapolis. Under Minneapolis Code Chapter 278, 'masters and journeymen' in the refrigeration and warm air/ventilation trades (as well as fuel gas fitting and steam and hot water) 'need the card in order to perform work in Minneapolis'. A Journeyman Warm Air Ventilation or Journeyman Refrigeration Certificate of Competency requires four years (1,600 hours per year) of on-the-job experience plus four years (576 hours) of trade-related education, or a state-approved apprenticeship; the Building Official approves eligibility (no application fee), the ICC exam is taken at Pearson VUE (100-question Journeyman Warm Air Ventilation exam or 70-question Journeyman Refrigeration exam, 70% to pass, $115), and the card costs $30 per trade. A failed exam requires a 60-day wait; scores are valid one year. Minneapolis has reciprocity only with Saint Paul: a Saint Paul card holder sends copies of the card and $30 per trade.
Saint Paul. The Department of Safety and Inspections requires Certificates of Competency (master and/or journeyman) in Warm Air/Ventilation, Refrigeration, Gas Burner, Oil Burner and Steam Fitting/Hot Water. Warm Air/Ventilation exams are held twice a year (January and July); refrigeration and burner candidates arrange testing through the Senior Mechanical Inspector. Journeymen must also carry an annual trade worker registration ($37 per trade for 0-4 years registered, $70 for 5-6 years, $59 for 7 or more). Reciprocal cards are issued on a current Minneapolis card for $24 per trade (Refrigeration at both levels; Warm Air and Ventilation at master level only).
Bloomington. Licenses mechanical contractors (HVAC, gas installer, hot water/steam, oil burner, refrigeration) on the strength of a Minneapolis or Saint Paul competency card or Bloomington's own $35 open-book mechanical test; no journeyman credential.
Rochester. Licenses HVAC Contractors ($125 per year) and individual HVAC Master Installers ($60 per year plus a $25 certificate of competency per area); no journeyman credential.
Duluth. Issues no mechanical license; a DLI-bonded mechanical contractor pulls the permit.
Out-of-state holders. None of these cities publish a reciprocity, endorsement or exam-waiver route for an HVAC license from another state. A journeyman arriving in Minnesota needs no credential to work for a bonded contractor outside Minneapolis and Saint Paul; inside those cities they should expect to document four years of experience and education and pass the city exam (or obtain one city's card and reciprocate to the other).
Minnesota master HVAC technician
Licensed by cities and counties
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.
How local licensing works in Minnesota
How local licensing works. Minnesota has no state mechanical or HVAC license and no state HVAC board. Under Minn. Stat. 326B.197 a business contracting for gas, heating, ventilation, cooling, air conditioning, fuel burning or refrigeration work files a $25,000 bond with DLI ($100 biennial filing fee); the bond is 'in lieu of all other bonds to any political subdivision' but does not replace city licenses, and DLI tells contractors they 'must comply with local licensing requirements'. Whether an individual must hold a master-level card depends on the city.
Minneapolis. Contractor licenses (HVAC Class A for installing, repairing or cleaning HVAC systems, HVAC Class B for cleaning only, Refrigeration Systems Installer, Gas Fitter) are issued by Business Licenses and Consumer Services and require the State of Minnesota $25,000 bond; the responsible person holds a Master Certificate of Competency under Minneapolis Code Chapter 278. Master Warm Air Ventilation and Master Refrigeration cards require four years (1,600 hours per year) of on-the-job experience and four years (576 hours) of trade-related education, eligibility approval by the Building Official (no fee), the ICC exam at Pearson VUE (80 questions, 75% to pass, $115; the refrigeration master exam is open book with a 3-hour limit) and a $30 card fee per trade. A Saint Paul card is accepted by reciprocity for $30 per trade. The city's contractor license fee is published on a fee page that could not be opened during verification.
Saint Paul. A Warm Air or Ventilation Business Trade License ($188 per year, expiring December 1) requires a current Saint Paul Master Warm Air and/or Ventilation Certificate of Competency or a current Minneapolis master card, the $25,000 DLI mechanical bond, a $500,000 certificate of insurance naming the city and workers' compensation proof; Refrigeration, Gas Burner, Oil Burner and Steam Fitting licenses follow the same pattern. Master competency exams for Warm Air/Ventilation are given in January and July; reciprocal master cards are issued on a current Minneapolis card for $24 per trade.
Rochester. An HVAC Contractor license ($125 per year) requires a full-time licensed HVAC Master Installer; the Master Installer license ($60 per year) is issued to the individual after a City of Rochester certificate of competency ($25 per area of competency).
Bloomington. Mechanical contractor licenses (HVAC, gas installer, hot water/steam, oil burner, refrigeration) require a Minneapolis or Saint Paul Certificate of Competency or passing Bloomington's $35 open-book mechanical test on the 2020 Minnesota Mechanical and Fuel Gas Code, plus the DLI bond and a Minnesota tax ID.
Duluth. No city mechanical license; permits are issued to DLI-bonded mechanical contractors.
Out-of-state holders. No Minnesota city reviewed here publishes reciprocity or endorsement for another state's master HVAC or mechanical contractor license. A master arriving from another state can contract statewide by filing the DLI bond, and in Minneapolis, Saint Paul or Rochester must additionally document four years of experience and education and pass that city's master exam (a Minneapolis card then reciprocates to Saint Paul and is accepted in Bloomington).
