Delaware trade license reciprocity

Delaware issues a statewide Journeyperson Electrician license through the Board of Electrical Examiners in the Division of Professional Regulation; a lesser Residential Electrician license (4,000 hours plus a residential exam) also exists. A new journeyperson must be at least 20 and either hold a certificate of completion from a Board-approved apprenticeship (no further exam) or document over 8,000 hours of full-time electrical work under a licensed master electrician (at least 4,000 of them directly under a master) and pass the Prov-administered journeyperson exam with 75%, using only the NEC as a reference. The application fee is $105. Out-of-state journeypersons are licensed by reciprocity under 24 Del. C. § 1409 without a Delaware exam: the Board decides case by case whether the origin state's requirements are substantially similar (Regulation 11.4 sets the benchmark at 4 years of supervised experience, a licensing exam and 5 hours of NEC continuing education) and otherwise requires five years of licensed practice. Unlike the master level, the Board publishes no list of substantially-similar states for journeypersons. Licenses run two years and renew with continuing education.

Delaware issues a person-held Master Electrician license through the Board of Electrical Examiners; it is the state's highest electrician credential and authorizes residential, commercial and industrial work. The Board also issues Master Electrician Special (restricted to specialties such as elevators, HVAC, signs, pools or primary distribution) and Limited Electrician licenses (residential-scale work, three years' experience), which are lesser credentials. A new master must show six years of full-time experience under a licensed master electrician, or four years plus two years of technical training, or a completed apprenticeship of 8,000 hours with 576 hours of related instruction, and pass the Prov-administered master exam with 75% using only the NEC as a reference; the application fee is $203 and proof of at least $300,000 general liability insurance is required before the license issues. Out-of-state masters are licensed by reciprocity without a Delaware exam under 24 Del. C. § 1409: the Board has published that Maryland and New Jersey standards are substantially similar (no experience proof) and that eighteen other jurisdictions are not, requiring five years of licensed practice; all other states are evaluated case by case. Licenses run two years and renew with continuing education.

Delaware does not issue a journeyman or journeyperson HVACR license. The Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners issues only Master Plumber, Master HVACR and Master HVACR Restricted licenses, and 24 Del. C. § 1820(c)(1) lets 'an apprentice, journeyman, mechanic or other person' provide HVACR services without a license while working under the supervision of a master HVACR licensee who is their employer or a full-time employee of the same business. An out-of-state journeyman license therefore has nothing to transfer to in Delaware and is neither required nor recognized for employment; technicians who service refrigerant-containing equipment still need federal EPA Section 608 certification. Delaware's own 'journeyman certificate' is a certificate of completion from a federally-registered HVACR apprenticeship program, which is an experience credential used toward the master license rather than a license: with it, 2 years of post-apprenticeship work under a master (in Delaware or under a similar-level licensee in another state) qualifies an applicant for the Master HVACR exam, and without it 7 years of supervised experience plus the Apprenticeship By-Pass exam are required. Out-of-state journeyman experience gained under a licensed master counts toward those requirements.

Delaware issues a person-held Master HVACR license through the Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners in the Division of Professional Regulation (the electrical trade is regulated by a separate board). A Master HVACR licensee may design, install, service and alter heating, air conditioning, refrigeration, ventilation and process systems including gas piping; a Master HVACR Restricted license covers one specialty (forced-air heating with ventilation and gas piping, hydronic heating with gas piping, commercial hood systems, refrigeration, air conditioning, or gas piping). Employees work under a master's supervision without their own license. A new master needs a journeyman certificate from a federally-registered apprenticeship plus 2 years under a master, or 7 years under a master plus the ABC Delaware Apprenticeship By-Pass exam, then passes the ProV-administered Master HVACR exam (100 questions, 4 hours, open book, 70%, $100) and pays the $173 application fee; a CFC (EPA 608) card is required. Out-of-state masters are licensed by reciprocity without a Delaware exam under 24 Del. C. § 1823: the Board has published that Connecticut and Maryland standards are substantially similar (no experience proof) and that fourteen other jurisdictions are not (7 years of licensed practice required); all other states are evaluated case by case. Licenses renew biennially with 5 hours of continuing education from 2026.
