Kentucky trade license reciprocity
How Kentucky licenses each trade and level, who it reciprocates with, and where a Kentucky license goes.
Electricians
Kentucky journeyman electrician · “Electrician”
Statewide license
Issued by Kentucky Department of Housing, Buildings and Construction (DHBC), Licensing Branch
Kentucky's journeyman-level credential is the statewide Electrician license issued by the Department of Housing, Buildings and Construction (DHBC) under KRS Chapter 227A; Kentucky does not use the word 'journeyman' in the license title, though the exam is called the Journeyman Electrician exam. A new applicant needs 8,000 hours of verifiable electrical experience since age 16 (an approved training course, two years of a four-year apprenticeship, an associate degree in electrical technology, or two years of teaching each substitute for 4,000 hours), must pass the open-book, 80-question Journeyman Electrician exam through Prov (3 hours; fee paid through DHBC), Pearson VUE ($100, 4 hours) or NASCLA with at least 70%, and pays a $100 biennial application fee prorated by birth month. Licenses run two years and renew with continuing education. DHBC's published reciprocity list covers only West Virginia and Virginia at this level; electricians from every other state document their hours and take the Kentucky exam.
Kentucky master electrician · “Master Electrician”
Statewide license
Issued by Kentucky Department of Housing, Buildings and Construction (DHBC), Licensing Branch
Kentucky issues a statewide Master Electrician license to individuals through the Department of Housing, Buildings and Construction (DHBC) under KRS 227A.060(2). A separate Electrical Contractor license (Form EL-2, $400 biennial, Business and Law exam, $1,000,000 general liability insurance and workers' compensation compliance) is the business credential and must always have a licensed master electrician associated with it. A new master applicant needs 16,000 hours of verifiable electrical experience since age 16 (an approved training course or two years of teaching substitutes for 4,000 hours; an associate degree in electrical technology for 6,000), must pass the open-book, 100-question Master Electrician exam through Prov (4 hours; fee paid through DHBC), Pearson VUE ($100, 5 hours) or NASCLA with at least 70%, and pays a $200 biennial application fee prorated by birth month. DHBC's published reciprocity list names Ohio (electrical contractor licensees receive both the Kentucky master and contractor licenses), West Virginia and Virginia (master electricians); applicants from all other states document their hours and take the Kentucky exam.
HVAC Technicians
Kentucky journeyman HVAC technician · “Journeyman HVAC Mechanic”
Statewide license
Kentucky issues a statewide Journeyman HVAC Mechanic license through the Department of Housing, Buildings and Construction (DHBC) under KRS 198B.650 to 198B.689; a journeyman performs HVAC work under the supervision, direction and responsibility of a licensed Master HVAC Contractor and supervises registered apprentices on site. A new applicant must be 18, a citizen or authorized resident alien, have two years of HVAC experience (at least 1,500 hours per year) either under a master HVAC contractor or as verifiable HVAC work in Kentucky or any other jurisdiction, pass the open-book Journeyman HVAC exam with at least 70% (offered through Prov for $80, or by the department for $50 on Form HVAC-4), and file Form HVAC 2 with a $50 twelve-month fee prorated by birth month ($29.17 to $75) and a passport photo. Licenses renew annually at $50 with continuing education. KRS 198B.666 and 815 KAR 8:010 Section 3 provide for licensure by reciprocity where an agreement exists with the licensing state, and the application form has a reciprocity checkbox, but DHBC's HVAC pages publish no list of partner states; every other out-of-state journeyman documents their hours and takes the Kentucky exam. Federal EPA Section 608 certification is required for refrigerant work but is not part of the DHBC application.
Kentucky master HVAC technician · “Master HVAC Contractor”
Statewide license
Kentucky's highest person-held HVAC credential is the statewide Master HVAC Contractor license issued by the Department of Housing, Buildings and Construction (DHBC) to an individual who qualified by examination; the master supervises and is primarily responsible for all HVAC work of the company he or she represents (a company may carry the required insurance in its name), and only a master or journeyman may purchase the statewide HVAC permits required since 2011. A new applicant must be 18, a citizen or authorized resident alien, and have two years as a licensed journeyman under a master HVAC contractor, two years as a master HVAC contractor 'or equivalent' in Kentucky or any other jurisdiction, or two years as a licensed mechanical engineer; pass the open-book Master HVAC exam, which covers codes and practices plus the law and regulation of the HVAC business, with at least 70% (Prov $80, or the department's exam for $150 on Form HVAC-4); carry general liability insurance of $500,000 and property damage insurance of $300,000 (KRS 198B.668) naming DHBC as certificate holder; and file Form HVAC 1 with a $250 twelve-month fee prorated by birth month ($145.83 to $375). Licenses renew annually at $250 with continuing education and current insurance. KRS 198B.666 authorizes licensure by reciprocity for states with substantially equal requirements that reciprocate, and Form HVAC 1 has a reciprocity checkbox requiring a letter of good standing; DHBC publishes no HVAC partner list, but Ohio's OCILB documents an active Kentucky-Ohio HVAC and refrigeration agreement. Federal EPA Section 608 certification is required for refrigerant work but is not verified by DHBC.
Plumbers
Kentucky journeyman plumber · “Journeyman Plumber”
Statewide license
Issued by Kentucky Department of Housing, Buildings and Construction (DHBC), Division of Plumbing
Kentucky issues a statewide Journeyman Plumber license through the Department of Housing, Buildings and Construction, Division of Plumbing, under KRS Chapter 318 and 815 KAR 20:030. A new applicant must have either two consecutive years as an apprentice plumber or a department-approved plumbing / Kentucky State Plumbing Code course plus one year as an apprentice, pass every portion of the department-administered Kentucky journeyman plumber examination (written, drawing, and practical) with at least 75 percent, file Form PLB-2 with a $60 license fee prorated to seven to eighteen months ending on the birth month, and register for the exam on Form PLB-3 ($50, passport photo). Exams run in February, May, August and November. Licenses renew annually at $60 with six hours of continuing education under 815 KAR 2:010 (waived for the first renewal if the initial license issued within twelve months of renewal). 815 KAR 20:030 does not waive the Kentucky exam for out-of-state journeymen, does not use the word reciprocity, and names no partner states; an inbound journeyman documents apprentice-level experience and sits the Kentucky exam.
Kentucky master plumber · “Master Plumber”
Statewide license
Issued by Kentucky Department of Housing, Buildings and Construction (DHBC), Division of Plumbing
Kentucky issues a statewide Master Plumber license through DHBC's Division of Plumbing under KRS Chapter 318 and 815 KAR 20:030. In-state applicants typically hold a Kentucky journeyman plumber license for at least two of the past five years and work under a licensed master for at least two years; Kentucky professional engineers with sufficient mechanical-engineering experience may also qualify. An applicant who holds a valid plumbing license issued by another state for at least two of the past five years, or who practiced as the equivalent of a master for four consecutive years in a state that does not license plumbers, may sit for Kentucky's exams but must still pass both the Kentucky journeyman examination (75% each portion) and the Kentucky master examination (80% each portion). The master exam is written plus drawing (more complex than the journeyman exam); the exam fee is $150 (Form PLB-3) and the license fee is $250 (Form PLB-1), prorated 7–18 months to the birth month. Masters renew annually at $250 with six CE hours and proof of insurance required by KRS 318.030. 815 KAR 20:030 names no partner states and does not waive the Kentucky exams.
Contractors
Kentucky residential contractor · “Building or residential contractor license or registration (city- or county-issued)”
Licensed by cities and counties
Issued by No state authority; cities and counties license or register residential building contractors
Kentucky issues no statewide residential building, home builder or home improvement contractor license, so an out-of-state residential builder has nothing at state level to transfer and no state reciprocity to apply for. What Kentucky does license is the trades: the Department of Housing, Buildings and Construction (HBC) says on its own home page that it "licenses/certifies plumbers, electricians, boiler contractors, sprinkler and/or fire alarm contractors and building inspectors", and its administrative regulations in Title 815 add heating, ventilation and air conditioning licensing, elevator safety, boilers and pressure vessels, manufactured homes and home inspectors. Anyone self-performing plumbing, electrical, HVAC, boiler or fire-protection work in Kentucky needs the matching HBC license whatever the local building rules say, and that is where the state-level reciprocity conversation belongs. Housing work itself is licensed jurisdiction by jurisdiction and the rules differ sharply: Louisville Metro issues a Building Type A - Residential contractor license with six hours of continuing education before each renewal, Lexington-Fayette registers a "general contractor, residential only" class under its Contractors Registration Ordinance, and the joint Bowling Green - Warren County Contractors Licensing Board issues a General Contractors License for remodeling and building. Owensboro and Covington sit at the other end: neither publishes a contractor competency license at all, and a builder there files an occupational business license and carries insurance instead. None of these credentials involves a trade or business-law exam, and none of them gives any weight to a license held in another state, so the practical work is registering in each place where permits will be pulled and carrying the insurance each one demands.
How local licensing works in Kentucky
How local licensing works. No Kentucky agency licenses residential builders or remodelers, and there is no state qualifying party, no state exam and no state reciprocity for this work. Each city and county decides for itself, so identify the building department with jurisdiction over the address before applying anywhere. A credential issued by one Kentucky jurisdiction does not carry into the next one, and none of the jurisdictions below grants anything for a license held in another state. Two statewide obligations apply wherever the project is: the HBC license for any self-performed plumbing, electrical, HVAC, boiler or fire-protection work, and compliance with the Kentucky Building Code adopted in 815 KAR Chapter 007.
Louisville Metro (Jefferson County). The Office of Construction Review issues the contractor licenses for the merged city-county. A builder chooses a term and then a scope. License A "lets you work on one or more permitted projects during a calendar year, which runs from January 1st to December 31st"; License B "allows you to work on only one permitted project during a calendar year." The scopes are Building A-Residential, Building A-Residential/Commercial, Building A-Commercial and Building B. Building Type A costs $125 a year and Building Type B $50 per permit, and "only one Building Type B license will be granted per person/company per renewal year." Six continuing education credit hours from a pre-approved list are required before renewal for Building A-R, Building A-RC and Building B, which is to say for everyone whose scope touches houses. The filing is a certificate of liability insurance naming the Office of Construction Review as certificate holder, workers' compensation and unemployment insurance or a signed and notarized affidavit that neither applies, an Occupational License Number from the Revenue Commission of Jefferson County on (502) 574-4860, and the application itself through the Metro business portal. Annual renewals must arrive with current liability insurance, the continuing education records for residential contractors, a workers' compensation form and a subcontractor list, and "any missing items will result in ALL items being returned." There is no exam, no experience requirement and no bond on the building categories; only the wrecking classes carry a written exam, a surety bond and a year of supervisory experience. Office of Construction Review, 444 S. 5th St., Suite 100, (502) 574-3321.
Lexington-Fayette Urban County. The Division of Building Inspection runs a Contractors Registration Ordinance: "this ordinance requires all contractors to register with the Building Inspection" and "unregistered contractors cannot obtain building permits." There are three classes under Ordinance 5-90(a). A general contractor, residential only "constructs up to 4-family homes (4-Plex), performs home remodeling, and may supervise, arrange, and/or perform more than two unrelated building trades or crafts." A general contractor covers everything larger. A specialty contractor "performs commercial, industrial, public works and residential construction and specializes in two or fewer unrelated building trades or crafts." Registration takes four steps: a $10 Home Office Certificate or a $25 Certificate of Occupancy if the business address is in Fayette County; an occupational business license from Revenue at 218 E. Main St., 2nd floor, (859) 258-3340; general liability insurance and workers' compensation with LFUCG as certificate holder, or the "Workers Comp Exempt" declaration on the application if neither applies; and the online Contractor Registration Application through the city's permitting portal with the occupational license and certificate of insurance uploaded. No exam, experience or bond is required for any of the three classes. The division's published fee schedule prices permits rather than registrations and lists no contractor registration fee, so ask Building Inspection for the current amount before filing. 101 E. Vine St., (859) 258-3770, [email protected].
Bowling Green and Warren County. A single joint Contractors Licensing Board licenses for both the city and the county under Ordinance 91-58 WC and Ordinance 91-25 BG. A General Contractors License is needed by anyone "doing any type of general contract work in Bowling Green / Warren County including pulling permits for building or remodeling, construction management, or if you would have two or more subcontractors per job", and costs $250. A Specialty Contractors License covers subcontract work or a job with at most one subcontractor, and costs $100. Both fees are non-refundable and renewals are annual, pro-rated for a mid-year filing. The filing is the application plus a certificate of insurance naming the board as certificate holder, with "a minimum requirement for General Liability Insurance [of] $100,000 per occurrence", workers' compensation coverage shown on the certificate or a notarized Affidavit of Exemption, and a notarized Partnership Agreement for a partnership. Licenses are non-transferable and "any change in ownership nullifies previous licenses." There is no exam and no experience review, and the board says so directly: "the Contractors Licensing Board does not warrant that you are otherwise qualified to perform your trade or specialty by the issuance of its license." A Bowling Green occupational license is also needed for work inside the city limits and a Warren County occupational license for work outside them. Contractors Licensing Board, 1141 State Street, Suite 200, 270-781-3530.
Owensboro and Daviess County. There is no Owensboro contractor license. The Owensboro Metropolitan Planning Commission's Building & Electrical Division "issues all building and electrical permits required by the Kentucky Building Code and National Electrical Code" for Owensboro-Daviess County, along with HVAC, sign and parking lot permits and certificates of occupancy, and it issues no contractor credential of any kind. What a builder needs instead is the city's business registration: "any person, partnership, corporation, or other legal entity must register with the Occupational License Division prior to conducting business inside the city limits", with "a minimum license fee of seventy-five ($75.00) dollars due with registration." New construction draws at least three field inspections - footer and foundation, framing and final - before a certificate of occupancy issues. Occupational License Division, 101 East 4th Street, 270-687-5600.
Covington and Kenton County (Northern Kentucky). Planning and Development Services of Kenton County is the building department for Covington and the surrounding communities, and its rule is short: "when completing work within Kenton County, all contractors must obtain and maintain a Kenton County occupational license and provide proof of Kentucky workers' compensation insurance coverage. In addition, the Kentucky Department of Housing, Buildings, and Construction requires a license for electrical, HVAC, plumbing, and fire suppression work. Contractors must provide copies of all these items before any permits can be issued." There is no residential builder license, exam or bond. In Covington itself a zoning permit from the city, and a certificate of appropriateness where a historic preservation overlay applies, must come before PDS will issue the building permit. PDS, 1840 Simon Kenton Way, Suite 3400, Covington, 859-331-8980; building permits 859-957-2408.
Storm-damaged communities. The Attorney General's Office of Consumer Protection runs joint emergency contractor registration programs with the City of Mayfield and Graves County, the City of Princeton and Caldwell County, the City of Dawson Springs and Hopkins County, and the City of Bremen and Muhlenberg County, "to register contractors looking to assist storm victims." The program "requires contractors to register prior to doing business", and registrants are issued placards that must be displayed on the job site and in the vehicle. It is a consumer-protection registration aimed at transient storm-chasers rather than a skill license, and it applies only in those communities. Details on (502) 871-2424.
Everywhere else. The remaining Kentucky cities and counties each set their own rules, from a full licensing board like Bowling Green's to nothing beyond an occupational license and proof of insurance. Ask the local building department what it requires before bidding, and expect to repeat the filing in each jurisdiction.
- Louisville Metro / Jefferson County (Office of Construction Review - Building Type A and B contractor licenses)
- Lexington-Fayette Urban County (Division of Building Inspection - general contractor, residential only registration)
- Bowling Green and Warren County (joint Contractors Licensing Board - General and Specialty Contractors License)
- Owensboro and Daviess County (Owensboro Metropolitan Planning Commission - permits only; city occupational license)
- Covington and Kenton County (Planning and Development Services of Kenton County - occupational license and insurance only)
Kentucky general contractor · “General or commercial building contractor license or registration (city- or county-issued)”
Licensed by cities and counties
Issued by No state authority; cities and counties license or register commercial building contractors
Kentucky has no statewide general, commercial or unlimited building contractor license, so there is nothing at state level for an out-of-state general contractor's license to transfer into, no qualifying party to designate with the state and no NASCLA route to take. The Department of Housing, Buildings and Construction licenses the trades instead - its home page says it "licenses/certifies plumbers, electricians, boiler contractors, sprinkler and/or fire alarm contractors and building inspectors", and 815 KAR adds HVAC licensing, elevator safety, boilers and pressure vessels, manufactured homes and home inspectors, with no chapter for building contractors anywhere in the title. Commercial building is controlled through local permitting, and the requirements are administrative rather than technical. Louisville Metro issues a Building Type A - Commercial license for $125 a year on a liability certificate, a workers' compensation filing and a Jefferson County occupational license number, with no exam and no bond. Lexington-Fayette registers a general contractor who "performs commercial, industrial, public works, and/or residential construction of larger than four-family homes" under its Contractors Registration Ordinance, and unregistered contractors cannot obtain building permits there. Bowling Green and Warren County run a joint Contractors Licensing Board whose $250 General Contractors License covers construction management and permit pulling, while telling applicants plainly that the license does not warrant that they are qualified. Owensboro and Covington require only an occupational business license and insurance. A commercial builder arriving in Kentucky therefore registers jurisdiction by jurisdiction and makes sure the plumbing, electrical, HVAC, boiler and fire-protection scope is performed under the correct HBC state licenses.
How local licensing works in Kentucky
How local licensing works. Kentucky has no state general contractor board, no state business-and-law exam for builders and no statewide reciprocity for commercial construction. Every rule that binds a general contractor is either a trade license from the Department of Housing, Buildings and Construction, the Kentucky Building Code in 815 KAR Chapter 007, or a local ordinance. Find the building department with jurisdiction over the site first, then register there before bidding. A registration in one Kentucky jurisdiction is worth nothing in the next, and an out-of-state general contractor license is worth nothing in any of them.
Louisville Metro (Jefferson County). The Office of Construction Review licenses building contractors for the merged city-county. License A covers "one or more permitted projects during a calendar year" and License B a single permitted project; the work scopes are Building A-Residential, Building A-Residential/Commercial, Building A-Commercial and Building B. Building Type A is "for building contractors seeking to obtain multiple permits within Louisville Jefferson County" at $125 a year on a term running 1 January to 31 December; Building Type B is $50 and is limited to one permit per person or company per renewal year. The filing is a certificate of liability insurance with the Office of Construction Review as certificate holder, workers' compensation and unemployment insurance or a notarized affidavit where the contractor has no covered employees, an Occupational License Number from the Revenue Commission of Jefferson County, and the application through the Metro business portal. The six-hour continuing education requirement attaches to the scopes that include housing - Building A-R, Building A-RC and Building B - so a contractor registered purely as Building A-Commercial is the one building class without it. Renewals must include a subcontractor list. There is no exam, experience review, bond or financial statement on any building class. 444 S. 5th St., Suite 100, (502) 574-3321.
Lexington-Fayette Urban County. The Division of Building Inspection registers every contractor under the Contractors Registration Ordinance, and "unregistered contractors cannot obtain building permits." The commercial class, under Ordinance 5-90(a)(1), is the general contractor, who "performs commercial, industrial, public works, and/or residential construction of larger than four-family homes (4-plex); and may supervise, arrange, and/or perform wholly or partly more than two building trades or crafts." A firm that concentrates on one or two trades registers as a specialty contractor instead. The filing is a Home Office Certificate ($10) or Certificate of Occupancy ($25) where the business address is in Fayette County, an occupational business license from Revenue, general liability and workers' compensation insurance with LFUCG named as certificate holder, and the online Contractor Registration Application with those two documents uploaded. No exam, experience or bond is required. The published Building Inspection fee schedule covers permits and lists no contractor registration fee, so confirm the amount with the division. 101 E. Vine St., (859) 258-3770.
Bowling Green and Warren County. One joint Contractors Licensing Board serves the city and the county under Ordinance 91-58 WC and Ordinance 91-25 BG. The General Contractors License, $250 and non-refundable, is required of anyone "doing any type of general contract work in Bowling Green / Warren County including pulling permits for building or remodeling, construction management, or if you would have two or more subcontractors per job." The Specialty Contractors License is $100 and covers subcontract work or a job with at most one subcontractor. Insurance is the substantive test: a certificate naming the board as certificate holder with general liability of at least $100,000 per occurrence, workers' compensation shown on the certificate or a notarized Affidavit of Exemption, and a notarized Partnership Agreement for partnerships. Licenses are non-transferable, renewals are annual and pro-rated mid-year, and a change of ownership voids the license. There is no exam or experience requirement; the board states that it "does not warrant that you are otherwise qualified to perform your trade or specialty by the issuance of its license." A city occupational license is needed for work inside Bowling Green and a county one for work outside it. 1141 State Street, Suite 200, 270-781-3530.
Owensboro and Daviess County. There is no contractor license here. The Owensboro Metropolitan Planning Commission's Building & Electrical Division issues building, electrical, HVAC, sign and parking lot permits and certificates of occupancy for Owensboro-Daviess County under the Kentucky Building Code and the National Electrical Code, and issues no contractor credential; demolition permits come from City of Owensboro Public Works. A commercial builder registers with the city's Occupational License Division before doing business inside the city limits, with a minimum license fee of $75 at registration. 101 East 4th Street, 270-687-5600.
Covington and Kenton County (Northern Kentucky). Planning and Development Services of Kenton County is the building department, and it requires that "all contractors must obtain and maintain a Kenton County occupational license and provide proof of Kentucky workers' compensation insurance coverage", plus the HBC state license "for electrical, HVAC, plumbing, and fire suppression work", with copies of all of it on file "before any permits can be issued." There is no general contractor license, exam or bond. In Covington a zoning permit precedes the building permit, and a certificate of appropriateness is needed first inside a historic preservation overlay. PDS, 1840 Simon Kenton Way, Suite 3400, Covington, 859-331-8980.
What does and does not travel. An out-of-state general contractor license, a NASCLA Accredited Examination and out-of-state project experience carry no weight in any Kentucky jurisdiction, because none of them tests or qualifies commercial builders. Kentucky is not a NASCLA participating state, and no Kentucky city on this page accepts an examination in place of its own filing. What does matter is holding, or employing someone who holds, the Department of Housing, Buildings and Construction license for each state-licensed trade in scope - plumbing, electrical, HVAC, boilers, fire sprinklers and fire alarms - because those licenses are statewide, are the only Kentucky construction credentials with reciprocity rules of their own, and are separately demanded by several of the local building departments above.
- Louisville Metro / Jefferson County (Office of Construction Review - Building A-Commercial licenses)
- Lexington-Fayette Urban County (Division of Building Inspection - general contractor registration under Ord. 5-90(a))
- Bowling Green and Warren County (joint Contractors Licensing Board - $250 General Contractors License)
- Owensboro and Daviess County (Owensboro Metropolitan Planning Commission - permits only; city occupational license)
- Covington and Kenton County (Planning and Development Services of Kenton County - occupational license and insurance only)
Home Inspectors
Kentucky home inspector · “Licensed Home Inspector”
Statewide license
Issued by Kentucky Board of Home Inspectors (Kentucky Real Estate Authority)
Kentucky licenses home inspectors statewide. The Kentucky Board of Home Inspectors is administered through the Kentucky Real Estate Authority and issues one credential, held by an individual rather than by a company: nobody may advertise or claim to be a home inspector, or inspect a residential dwelling for compensation, without it. There is a single grade, with no apprentice, associate or trainee tier below it and nothing above it, so the license an inbound inspector seeks is simply the home inspector license. No Kentucky city or county may add a home inspector license or registration of its own, although a local occupational license tax can still apply. Every licensee carries general liability insurance of at least $250,000 naming the Board as certificate holder, and every fee-paid inspection follows the standards of practice of either the American Society of Home Inspectors or the International Association of Certified Home Inspectors, whichever the inspector names on the application. Architects, professional engineers, licensed plumbers, electricians, HVAC mechanics, real estate licensees, appraisers and several other trades are exempt when they act inside their own license.
