Louisiana trade license reciprocity
How Louisiana licenses each trade and level, who it reciprocates with, and where a Louisiana license goes.
Electricians
Louisiana journeyman electrician
Licensed by cities and counties
Louisiana does not issue a statewide journeyman electrician license. The only state electrical credential is the Louisiana State Licensing Board for Contractors (LSLBC) commercial contractor license with the Electrical classification, required for any electrical project of $10,000 or more; it is issued to the contracting business (or to an individual as a sole proprietor) on the strength of a qualifying party who passed the trade exam, and the LSLBC FAQ and Types of Licenses pages list no journeyman or master electrician license. Journeyman licensing exists only where a parish or city ordinance creates it: New Orleans issues a Class 'D' Journeyman Electrical License ($60 per year) to applicants who pass the ICC F17 National Standard Journeyman Electrician exam, Jefferson Parish administers its own electrical exam and requires a parish-licensed electrician to file electrical permits, and Shreveport directs journeyman and master candidates to ICC testing while requiring contractor registration with the city. None of these jurisdictions publish a reciprocity or endorsement rule for out-of-state journeyman licenses; in practice the portable credential is the ICC National Standard Journeyman Electrician exam, which several cities accept directly. An out-of-state journeyman who only wants to work as an employee needs whatever local card the parish or city requires, and nothing at the state level.
How local licensing works in Louisiana
How local licensing works. The Contractors Licensing Law (La. R.S. 37:2150.1 et seq.) regulates contractors: an electrical contractor is anyone who contracts for electrical work valued at $10,000 or more, and the LSLBC licenses the business through a designated qualifying party. Individual electricians are licensed, where at all, by parish or city ordinance, and requirements differ by jurisdiction.
New Orleans. The Department of Safety and Permits issues a Class 'E' Electrician Trainee license ($30 per year, sponsored by a Class 'A' master license holder or union representative) and a Class 'D' Journeyman Electrical License ($60 per year, delinquent fee $5 per month). The journeyman applicant must be 18 or older and submit a passing ICC Official Results Report for exam F17 National Standard Journeyman Electrician (an unofficial stamped report is not accepted), a passport-style photo and ID; a journeyman must be employed by and work under a Class 'A' electrical contractor. The city page states no experience-hour requirement and no reciprocity for other jurisdictions' licenses; an out-of-state journeyman who has already passed the ICC F17 exam can apply on that score.
Jefferson Parish. The Department of Inspection and Code Enforcement publishes an Electrical Exam Application and requires that electrical permit filings be made by a Jefferson Parish licensed electrician; the parish trade contractor license costs $200 and lists the state license among its checklist items. The exam application is a scanned document whose eligibility text could not be read, and no reciprocity rule was found on the parish site.
Shreveport. The city requires every contractor performing electrical work to register with the city and refers journeyman or master testing to the International Code Council or the LSLBC; electrical work over $10,000 requires the state license.
Baton Rouge and Lafayette. No official page describing a journeyman electrician license or exam was located for the City of Baton Rouge/East Baton Rouge Parish or for Lafayette Consolidated Government; their permit pages cover permitting and inspection only. Applicants should contact the local building official.
Out-of-state holders. No parish or city page reviewed publishes reciprocity or endorsement for journeyman licenses from other states. The LSLBC's reciprocity (trade-exam waiver for anyone who passed another state's exam) applies only to its contractor license.
Louisiana master electrician
Licensed by cities and counties
Louisiana does not issue a statewide master electrician license. The state-level credential for electrical work is the Louisiana State Licensing Board for Contractors (LSLBC) commercial license with the Electrical classification, mandatory for any electrical project of $10,000 or more; it is a contractor license issued to the business (or to a sole proprietor) and qualified by a natural person, the qualifying party, who passed the Electrical trade exam through PSI, so it is treated here as a business license rather than a person-held master credential, even though Texas recognizes the Louisiana statewide license as master-equivalent. Master electrician licenses exist only at the local level: New Orleans issues a Class 'A' Master Electrical License ($125 per year) to an applicant who passed the ICC F49 Electrical Contractor exam or holds the LSLBC statewide license as its qualifying party, carries $500,000 of general liability insurance, and is the only Class 'A' holder for the company; Jefferson Parish issues a parish trade contractor license ($200) built on the state license. For the state contractor license the LSLBC waives the trade exam for any applicant who passed a comparable classification exam in any other state, with no partner-state list since October 23, 2024, but the Business and Law course/exam, the financial statement and the other licensing requirements are never waived. No parish or city page reviewed publishes reciprocity for out-of-state master licenses.
How local licensing works in Louisiana
State contractor license (not a master license). Under La. R.S. 37:2150.1 an electrical contractor is anyone contracting for electrical work of $10,000 or more, and the LSLBC issues the commercial license to that person or business with an Electrical classification qualified by a designated qualifying party. Applicants file the online application with a financial statement (required of all applicants), Secretary of State registration for any business entity including out-of-state companies, the online Business and Law course/exam, and the PSI trade exam for the classification; statutory fee caps are $50 per examination, $100 license and $100 renewal, plus a surcharge of up to $400 that the board may assess on a contractor not domiciled in Louisiana. Reciprocity for the state license: R.S. 37:2153(F)(5) directs the board to waive the trade portion of the exam for an applicant licensed in a comparable classification in another state on written certification that the applicant passed that classification's exam and is in good standing, and the Executive Director's October 23, 2024 letter extends this to any state: a classification exam passed in any other state 'with no waivers, exemptions, or grandfathering in effect' is accepted for the equivalent Louisiana classification, and all previous state-to-state agreements were declared null and void. The applicant has the origin board complete the Reciprocity Request form (license status, disciplinary history, and the name, exam developer, date and score of each person who passed the trade exam) and uploads it with the application; the exam/administrative fee is still charged, and the business law requirement 'shall not be waived'.
New Orleans. The Class 'A' Master Electrical License doubles as the city's electrical contractor license: the applicant submits a passing ICC Official Results Report for exam F49 Electrical Contractor, or a copy of the LSLBC statewide license with the qualifying party letter, plus certificates of general liability insurance of at least $500,000 and workers' compensation naming the City as certificate holder; the license costs $125 per year active or $30 inactive, with a $10 per month delinquent fee, and only one Class 'A' holder is allowed per company. The city page states no experience requirement and no reciprocity.
Jefferson Parish. A parish trade contractor license ($200 new) is issued to a license holder/qualifying party and lists the state license, occupational license, sales tax registration, liability insurance and workers' compensation on its checklist; the parish also administers its own electrical exam.
Shreveport. Requires city contractor registration for anyone performing electrical work and the state license for work over $10,000; master testing is referred to the ICC or the LSLBC.
Baton Rouge and Lafayette. No official page describing a master electrician license was located for East Baton Rouge Parish or Lafayette Consolidated Government.
Out-of-state holders. A master electrician from another state who wants to contract in Louisiana applies for the LSLBC commercial license and, if the master license was earned by a trade exam, requests the trade-exam waiver by reciprocity; the Business and Law course and financial statement are still required. City licenses such as New Orleans Class 'A' can then be obtained on the state license or the ICC F49 exam.
HVAC Technicians
Louisiana journeyman HVAC technician
Licensed by cities and counties
Louisiana does not issue a statewide journeyman or technician license for heating, air conditioning or refrigeration work. The only state HVAC credential is the Louisiana State Licensing Board for Contractors (LSLBC) commercial contractor license in the Mechanical classification (or its Heat, Air Conditioning, Ventilation, Duct Work and Refrigeration subclassification), required for any mechanical project of $10,000 or more and issued to the contracting business or sole proprietor on the strength of a qualifying party who passed the trade exam; the LSLBC's FAQ and Types of Licenses pages list no journeyman, master or technician license. Journeyman mechanic licensing exists only where a city or parish ordinance creates it: New Orleans issues a Class 'B' Journeyman Mechanical Contractor License ($55 per year) to applicants who pass the ICC G31 National Journeyman Mechanical exam and work under a Class 'A' air conditioning and refrigeration contractor, Jefferson Parish requires air conditioning and heating equipment to be installed or replaced by a parish-licensed mechanical contractor, and Shreveport registers contractors and refers journeyman and master testing to the ICC or the LSLBC. Under La. R.S. 37:2156.1(I), however, employees of a statewide-licensed mechanical contractor cannot be required to pass any local examination or certification as a condition of working for that contractor, so a local journeyman card matters mainly to technicians working for contractors below the state threshold or outside the state system. None of these jurisdictions publish reciprocity for out-of-state journeyman licenses; the portable credential in practice is the ICC journeyman mechanical exam. Federal EPA Section 608 certification is required of anyone who handles refrigerants.
How local licensing works in Louisiana
How local licensing works. The Contractors Licensing Law (La. R.S. 37:2150.1 et seq.) regulates contractors: a mechanical contractor is anyone who contracts for air conditioning, refrigeration, heating, plumbing, ventilation, boiler or piping work valued at $10,000 or more, and the LSLBC licenses the business through a designated qualifying party. Individual mechanics and technicians are licensed, where at all, by parish or city ordinance, and R.S. 37:2156.1(I) preempts local examination or certification of the employees of a statewide-licensed mechanical contractor when they work for that contractor.
New Orleans. The Department of Safety and Permits issues a Class 'B' Journeyman Mechanical Contractor License covering mechanics (air conditioning and refrigeration) and gasfitters. A mechanic applicant must be 18 or older and submit a passing ICC Official Results Report for exam G31 National Journeyman Mechanical (unofficial stamped reports are not accepted), a driver's license or state ID, a passport-style photo taken within the last 3 to 6 months, the mechanical license application and a signed Journeyman Acknowledgement. The license costs $55 per year, expires on the holder's birthday (delinquent fee $5 per month; a license delinquent more than two years requires retesting with ICC), and the journeyman must be employed by and work under the supervision of a Class 'A' Air Conditioning and Refrigeration Contractor. The city page states no experience-hour requirement and no reciprocity for other jurisdictions' licenses; an out-of-state journeyman who has already passed the ICC G31 exam can apply on that score.
Jefferson Parish. The Department of Inspection and Code Enforcement requires that installation or replacement of air conditioning and heating equipment, including any condenser, be filed by a Jefferson Parish licensed mechanical contractor; the parish issues a $200 trade contractor license to a license holder/qualifying party whose checklist includes the state license. No separate journeyman mechanic card or reciprocity rule was found on the parish site.
Shreveport. The city requires every HVAC contractor performing work in the city to hold a city contractor's registration and the state license for work over $10,000, and refers HVAC journeyman and master testing to the International Code Council or the LSLBC.
Baton Rouge and Lafayette. No official page describing a journeyman mechanic license or exam was located for the City of Baton Rouge/East Baton Rouge Parish or Lafayette Consolidated Government; their permit pages cover permitting and inspection only. Applicants should contact the local building official.
Out-of-state holders. No parish or city page reviewed publishes reciprocity or endorsement for journeyman HVAC licenses from other states. The LSLBC's reciprocity (trade-exam waiver for anyone who passed another state's exam) applies only to its contractor license.
Louisiana master HVAC technician
Licensed by cities and counties
Louisiana does not issue a statewide master HVAC or master mechanic license. The state-level credential for HVAC work is the Louisiana State Licensing Board for Contractors (LSLBC) commercial license in the Mechanical classification (major classification 6, or subclassification 6.1 Heat, Air Conditioning, Ventilation, Duct Work and Refrigeration), mandatory for any mechanical project of $10,000 or more; it is a contractor license issued to the business (or a sole proprietor) and qualified by a natural person, the qualifying party, who passed the trade exam through PSI, so it is treated here as a business license rather than a person-held master credential. Master mechanic licenses exist only at the local level: New Orleans issues a Class 'A' Master Mechanical Contractor License ($110 per year) to an applicant who passed the ICC G29 Master Mechanical exam directly or through LSLBC state testing, carries $500,000 of general liability insurance, and is the only Class 'A' holder for the company; Jefferson Parish issues a $200 parish trade contractor license built on the state license. For the state contractor license the LSLBC waives the trade exam for any applicant who passed a comparable classification exam in any other state without waivers, exemptions or grandfathering, with no partner-state list since October 23, 2024, but the Business and Law course/exam, the financial statement and the other licensing requirements are never waived. No parish or city page reviewed publishes reciprocity for out-of-state master licenses. Federal EPA Section 608 certification applies to anyone who handles refrigerants.
How local licensing works in Louisiana
State contractor license (not a master license). Under La. R.S. 37:2150.1(16) a mechanical contractor is anyone contracting for air conditioning, refrigeration, heating, plumbing, ventilation, boiler or piping work of $10,000 or more, and the LSLBC issues the commercial license to that person or business with a Mechanical classification (or the 6.1 Heat, Air Conditioning, Ventilation, Duct Work and Refrigeration subclassification) qualified by a designated qualifying party. Applicants file the online application with a financial statement (required of all applicants), Secretary of State registration for any business entity including out-of-state companies, the online Business and Law course/exam, and the PSI trade exam for the classification (PSI has administered all LSLBC trade exams since August 5, 2025); statutory fee caps are $50 per examination, $100 license and $100 renewal, plus a surcharge of up to $400 that the board may assess on a contractor not domiciled in Louisiana. Reciprocity for the state license: R.S. 37:2153(F)(5) directs the board to waive the trade portion of the exam for an applicant licensed in a comparable classification in another state on written certification that the applicant passed that classification's exam and is in good standing, and the Executive Director's October 23, 2024 letter extends this to any state: a classification exam passed in any other state 'with no waivers, exemptions, or grandfathering in effect' is accepted for the equivalent Louisiana classification, and all previous state-to-state agreements were declared null and void. The applicant has the origin board complete the Reciprocity Request form (license status, disciplinary history, and the name, exam developer, date and score of each person who passed the trade exam) and uploads it with the application; the exam/administrative fee is still charged, and the business law requirement 'shall not be waived'. Once licensed, R.S. 37:2156.1(I) exempts the contractor and its employees from any parish or city examination or certification.
New Orleans. The Class 'A' Master Mechanical Contractor License covers air conditioning and refrigeration (and, separately, gasfitters): the applicant submits a passing ICC Official Results Report for exam G29 Master Mechanical, obtained from ICC directly or through state testing with the LSLBC, plus certificates of general liability insurance of at least $500,000 and workers' compensation naming the City as certificate holder, a photo and ID; the license costs $110 per year active or $25 inactive, with a $10 per month delinquent fee, renews from 90 days before the holder's birthday, and only one Class 'A' holder is allowed per company. The city page states no experience requirement and no reciprocity.
Jefferson Parish. A parish trade contractor license ($200 new) is issued to a license holder/qualifying party for mechanical work and lists the state license, occupational license, sales tax registration, liability insurance and workers' compensation on its checklist; air conditioning and heating equipment may be installed or replaced only under a filing by a parish-licensed mechanical contractor.
Shreveport. Requires city contractor registration for anyone performing HVAC work and the state license for work over $10,000; master testing is referred to the ICC or the LSLBC.
Baton Rouge and Lafayette. No official page describing a master mechanic license was located for East Baton Rouge Parish or Lafayette Consolidated Government.
Out-of-state holders. A master HVAC contractor from another state who wants to contract in Louisiana applies for the LSLBC commercial license with the Mechanical classification and, if the origin license was earned by a trade exam, requests the trade-exam waiver by reciprocity; the Business and Law course and financial statement are still required. City licenses such as New Orleans Class 'A' can then be obtained on the ICC G29 exam or LSLBC testing.
