Colorado trade license reciprocity
How Colorado licenses each trade and level, who it reciprocates with, and where a Colorado license goes.
Electricians
Colorado journeyman electrician · “Journeyman Electrician”
Statewide license
Issued by Colorado State Electrical Board (DORA Division of Professions and Occupations)
Colorado issues a statewide Journeyman Electrician license through the State Electrical Board within DORA's Division of Professions and Occupations. There are three routes: examination (8,000 hours over at least four years, 288 hours of classroom education, and the PSI-administered Colorado exam), endorsement of an active state-issued license obtained by exam on the NEC edition Colorado currently uses, and reciprocity for journeymen from the 14 NERA member states. Endorsement and reciprocity both issue the license without a Colorado exam. Applications are filed through DPO Online Services; licenses expire September 30 every three years.
Colorado master electrician · “Master Electrician”
Statewide license
Issued by Colorado State Electrical Board (DORA Division of Professions and Occupations)
Colorado issues a statewide Master Electrician license through the State Electrical Board within DORA's Division of Professions and Occupations. A master license can be obtained only by examination or by endorsement; Board Rule 1.7 states that a Colorado master electrician's license may not be granted by reciprocity, so there are no master-level reciprocity agreements. By examination an applicant needs 10,000 hours of experience over at least five years (or a qualifying degree with fewer hours) and must pass the PSI-administered Colorado master exam. By endorsement an applicant who holds or has held an active state-issued master license obtained by exam on the NEC edition Colorado currently uses, and who documents 10,000 hours over five years, is licensed without the Colorado exam. Licenses expire September 30 every three years.
HVAC Technicians
Colorado journeyman HVAC technician
Licensed by cities and counties
Colorado has no state HVAC license at any level; the Department of Regulatory Agencies licenses electricians and plumbers but no mechanical, heating, air conditioning or refrigeration trade, and the Pikes Peak Regional Building Department's exam notice states plainly that 'Colorado does NOT have a state license for the building or mechanical trades.' Journeyman-level HVAC credentials exist only where a city or regional building department issues them. Denver issues Heating and Ventilating Journeyman and Refrigeration Journeyman certificates (4 years / 7,000 hours of field experience plus the ICC F31 Journeyman Mechanical exam, $40 for three years), and the Pikes Peak Regional Building Department in Colorado Springs and El Paso County issues a Heating Mechanic IV (HVAC Service Technician) license for technicians employed by a licensed mechanical contractor. Most other Colorado jurisdictions license only the contractor and require no card for employees. An out-of-state journeyman HVAC license is not recognized by Denver, which does not reciprocate certificates from other states, or by PPRBD, which accepts no out-of-state exams; the applicant must document experience locally and pass the ICC exam each jurisdiction uses. EPA Section 608 certification is required nationwide to handle refrigerants.
How local licensing works in Colorado
How local licensing works. There is no state HVAC board; each city, county or regional building department decides whether to license mechanical workers and contractors under its own building code, and most use ICC National Standard exams administered through Pearson VUE ($100 per exam). Passing an ICC exam is not itself a license, and jurisdictions decide individually whether to honor it.
Denver. Community Planning and Development issues person-held Heating and Ventilating Journeyman and Refrigeration Journeyman certificates. Each requires 4 years (at least 7,000 hours) of field installation experience through an apprenticeship or on-the-job training, proven by notarized letters from employers or clients covering projects completed within the last 10 years, plus a passing letter for the ICC #F31 National Standard Journeyman Mechanical exam submitted within 90 days of application approval. The certificate fee is $40 and it renews every 3 years. Denver states that it 'does not accept or reciprocate contractor licenses and/or certificates from other counties or states.'
Colorado Springs and El Paso County (Pikes Peak Regional Building Department). PPRBD issues individual Heating Mechanic licenses: Heating Mechanic I (Fitter) for gas piping after 1 year of experience, and Heating Mechanic IV (HVAC Service Technician) for repairing and servicing HVAC equipment while employed by a licensed Mechanical Contractor A, B, C or D. Applicants pay a $50 application fee and a $10 annual license fee, pass the ICC National Standard Journey Mechanical exam (W31) where applicable, and hold combustible gas indicator and carbon monoxide detection instrument certificates; the Licensing Committee and Board of Review approve each application after a judicial record check. PPRBD accepts only ICC exams passed on or after January 1, 2016 and states that 'no out-of-state exams will be accepted.' Heating Mechanic IV renewal requires 6 hours of approved technical training.
Other jurisdictions. Denver's and PPRBD's pages were the only individual HVAC worker licenses verified for this entry; other Colorado jurisdictions (for example Aurora, Fort Collins, Boulder County and Jefferson County) generally license mechanical contractors only and were not checked for journeyman cards.
Out-of-state holders. Neither Denver nor PPRBD publishes a reciprocity or endorsement path for journeyman licenses from other states. An arriving journeyman should expect to document experience with notarized letters and pass the ICC journeyman mechanical exam for each jurisdiction that licenses individuals.
Colorado master HVAC technician
Licensed by cities and counties
Colorado issues no state master HVAC, mechanical or contractor license; the state licenses only electricians and plumbers, and mechanical licensing is left entirely to cities, counties and regional building departments. The master-level credential is therefore a local supervisor certificate or mechanical contractor license. Denver issues person-held Heating and Ventilating Class A and Class B and Refrigeration Class A and Class B supervisor certificates (6 to 8 years of experience plus the ICC F29 Master Mechanical or F32 Residential Mechanical exam, $60 for three years) and then licenses the mechanical contractor that employs the certificate holder ($250 for three years). The Pikes Peak Regional Building Department licenses Mechanical Contractors in classes H-A commercial, H-B residential and H-C specialty classes on the ICC W29 Master Mechanical, W32 Residential Mechanical or N33 Master Gas Pipe Fitter exams ($100 per license plus a $50 application fee). Neither jurisdiction recognizes out-of-state licenses: Denver does not reciprocate certificates from other counties or states and PPRBD accepts no out-of-state exams, so an arriving master HVAC contractor documents experience locally and passes the ICC exam required by each jurisdiction where they will pull permits.
How local licensing works in Colorado
How local licensing works. With no state mechanical license, each Colorado jurisdiction licenses mechanical contractors under its own code, nearly always on ICC National Standard exams (Pearson VUE, $100 each). PPRBD's notice says that 'often, contractors who work in several areas must pass an exam in each jurisdiction,' although many jurisdictions honor the same ICC certificate.
Denver. Licensing is a two-step process. First the individual obtains a supervisor certificate: Heating and Ventilating Class A (commercial and residential heating, ventilation and cooling up to 50 tons; 8 years of experience, 4 as a journeyman and 4 in design or supervision; ICC #F29 National Standard Master Mechanical), Heating and Ventilating Class B residential only (6 years; ICC #F32 National Standard Residential Mechanical), Heating, Ventilating, A/C residential only (6 years each in heating/ventilation and refrigeration; ICC #F32; refrigeration up to 5 tons), Refrigeration Class A (8 years; ICC #F29) or Refrigeration Class B residential only (6 years; ICC #F32). Experience is documented with notarized letters from employers or clients for projects completed within the last 10 years, and the ICC pass letter is due within 90 days of approval. Supervisor certificates cost $60 and renew every 3 years. Second, the business applies for a mechanical contractor license ($250, 3 years), which must be held by or employ a certificate holder. Denver 'does not accept or reciprocate contractor licenses and/or certificates from other counties or states.'
Colorado Springs and El Paso County (PPRBD). Mechanical Contractor licenses: H-A Mechanical Commercial (ICC W29 Master Mechanical), H-B Mechanical Residential (ICC W32 Residential Mechanical), H-C1 Gas Piping (ICC N33 Master Gas Pipe Fitter), H-C2 Commercial Refrigeration, H-C3 Residential Maintenance/Repair and H-C4 Residential Remodeling, each with a $100 license fee, plus a $50 application fee, references documenting relevant experience, a liability insurance certificate naming PPRBD (minimums in RBC201.7) and a name-based judicial record check; the Licensing Committee and Board of Review act on each application monthly. PPRBD accepts ICC National Standardized or ICC Colorado Standard exams passed on or after January 1, 2016 and 'no out-of-state exams will be accepted.'
Other jurisdictions. Only Denver and PPRBD were verified for this entry; other Colorado cities and counties license mechanical contractors under similar ICC-based ordinances and should be checked individually.
Out-of-state holders. No Colorado jurisdiction checked publishes reciprocity or endorsement for another state's master HVAC or mechanical contractor license. The practical route is to pass the ICC National Standard Master Mechanical (or Residential Mechanical) exam once and apply in each jurisdiction, each of which separately verifies experience.
