Quick answer: Kentucky licenses only three trades at the state level – plumbers, electricians and HVAC contractors – all through the Department of Housing, Buildings & Construction (HBC). Plumbers are licensed under KRS Chapter 318, electricians under KRS Chapter 227A, and HVAC contractors and mechanics under KRS 198B.650–198B.740. There is no statewide general-contractor license, and no state license for roofing, painting, carpentry, landscaping, handyman work or cleaning. Those trades are unregulated at the state level, though cities and counties (such as Louisville Metro, Lexington and Bowling Green) commonly require local contractor registration, permits and insurance.
The table below shows which of the common trades need a Kentucky state license and which do not.
Which trades need a license in Kentucky?
| Trade | State license required? | Licensing body |
|---|---|---|
| Plumber | Yes | State license required – HBC Division of Plumbing under KRS Chapter 318. Issued as Master Plumber or Journeyman Plumber. |
| Electrician | Yes | State license required – HBC Electrical Division under KRS Chapter 227A. Issued as Electrical Contractor, Master Electrician or Electrician (815 KAR 35:060). |
| HVAC | Yes | State license required – HBC HVAC Division under KRS 198B.650–198B.740. Issued as Master HVAC Contractor or Journeyman HVAC Mechanic (815 KAR 8:010). |
| General Contractor | No | No statewide general-contractor license in Kentucky. Many cities and counties (e.g., Louisville Metro, Lexington, Bowling Green) require local registration, permits and insurance. |
| Roofer | No | No state roofing-contractor license. Local registration and building permits may apply; any electrical, plumbing or HVAC work must be done by the licensed trade. |
| Painter | No | No state license for painting. Local business registration may still apply. |
| Carpenter | No | No state license for general carpentry, cabinetry or remodeling – unless the job crosses into a state-licensed trade (electrical, plumbing or HVAC). |
| Landscaper | No | No state contractor license for general landscaping or lawn care. Separate rules apply to pesticide application (Kentucky Dept. of Agriculture). |
| Handyman | No | No state handyman license. Local registration and permits may apply, and a handyman cannot perform work reserved for a licensed plumber, electrician or HVAC contractor. |
| Cleaner | No | No state occupational or contractor license required for residential or commercial cleaning. |
"Yes" means an HBC-issued state license is required; unlicensed trades may still need local registration or a business license, and must not perform work reserved for a licensed plumber, electrician or HVAC contractor.
How Kentucky licenses the trades
Unlike many states, Kentucky regulates only its mechanical trades at the state level. The Department of Housing, Buildings & Construction (HBC) – part of the Public Protection Cabinet – licenses plumbers, electricians and HVAC contractors statewide, and also certifies boiler, sprinkler and fire-alarm contractors and building inspectors. Three HBC divisions do this work: the Division of Plumbing (KRS Chapter 318), the Electrical Division (KRS Chapter 227A), and the HVAC Division (KRS 198B.650–198B.740).
Crucially, Kentucky has no statewide general-contractor license. A person building homes or running a construction business does not obtain a state GC license; instead, the licensed trades within a project (plumbing, electrical, HVAC) must be performed by state-licensed tradespeople, while general-contracting itself is governed by local city and county rules.
The state-licensed trades in detail
Plumbers are licensed by the HBC Division of Plumbing under KRS Chapter 318, which authorizes the division to examine and license Master Plumbers and Journeyman Plumbers, approve plans and issue plumbing permits.
Electricians are licensed by the HBC Electrical Division under KRS Chapter 227A and 815 KAR 35:060, which establishes three individual credentials – Electrician, Master Electrician and Electrical Contractor – plus a provisional electrician license. A contracting business must employ a licensed Master Electrician and hold an Electrical Contractor license backed by insurance.
HVAC professionals are licensed under KRS 198B.650–198B.740 and 815 KAR 8:010, which establish the Master HVAC Contractor and Journeyman HVAC Mechanic licenses, along with an apprentice registration. These are the trades where hiring an unlicensed person is illegal and can void permits, insurance and warranties.
Trades with no Kentucky state license
Most common home-service trades are not licensed by the state at all: general contracting, roofing, painting, carpentry/cabinetry, landscaping and lawn care, handyman work, and cleaning. Kentucky simply does not issue a state credential for these scopes.
Being unlicensed at the state level does not mean being unregulated. These businesses still typically need a local business license or contractor registration, must carry appropriate insurance, and cannot cross into a licensed scope. For example, a handyman, roofer or carpenter cannot legally perform electrical, plumbing or HVAC work reserved for a licensed tradesperson under KRS 318, KRS 227A or KRS 198B.
Local city and county requirements
Because there is no state GC license, local governments fill the gap. Requirements vary widely by jurisdiction and often include registration, fees, proof of insurance and permits:
Louisville-Jefferson County requires contractors to be licensed through Louisville Metro's codes and regulations department. Lexington-Fayette requires contractors to register their business with the city. Bowling Green (Warren County) requires a General Contractor license from its local Contractor Licensing Board. Always confirm requirements with the city or county building department before starting a job, since local permit thresholds and registration rules differ across Kentucky.
Permits and hiring the right trade
Even where a trade is unlicensed, a building permit is still required for many projects, and the licensed portions of the work – plumbing, electrical and HVAC – must be performed and permitted by state-licensed professionals. The HBC provides an online public portal for license verification and permit applications across its Building Code Enforcement, Electrical, HVAC, Plumbing, Manufactured Housing and Fire Prevention divisions.
When hiring, verify a plumber's, electrician's or HVAC contractor's license through the HBC lookup, confirm local registration for a general contractor or specialty trade, and make sure any electrical, plumbing or mechanical work is quoted by a properly licensed contractor rather than a general handyman.
How to get licensed in Kentucky
- Identify your trade and whether Kentucky licenses it at the state level – only plumbing (KRS 318), electrical (KRS 227A) and HVAC (KRS 198B) require an HBC state license; general contracting and most other trades do not.
- For a state-licensed trade, meet the experience requirements for your credential – for example, a Master Plumber must have held a Journeyman license and worked under a Master Plumber, and a Master Electrician needs documented years of electrical experience.
- Apply to the appropriate HBC division and pass the required state examination (Plumbing, Electrical Form EL-3, or HVAC), scoring at least the minimum passing grade, and submit fees, insurance and any required bond.
- If you are a general contractor or a non-state-licensed trade, register with each city or county where you work – for example Louisville Metro, Lexington or Bowling Green – and obtain any required local business license, bond, insurance and permits.
- Keep your HBC license active by renewing on its cycle (electrical and other credentials renew biennially) and completing any required continuing education, and pull building permits for work that requires them.

Frequently asked questions
Does Kentucky require a general contractor license?
No. Kentucky does not issue a statewide general-contractor license. Only plumbers, electricians and HVAC contractors are licensed at the state level by the Department of Housing, Buildings & Construction. General contractors are instead regulated locally – many cities and counties, such as Louisville Metro, Lexington and Bowling Green, require registration, insurance and permits before you can work.
Which trades need a state license in Kentucky?
Three: plumbers (HBC Division of Plumbing, KRS 318), electricians (HBC Electrical Division, KRS 227A) and HVAC contractors and mechanics (HBC HVAC Division, KRS 198B.650–198B.740). Roofing, painting, carpentry, landscaping, handyman work and cleaning have no state license, though local registration may still apply.
Does a handyman need a license in Kentucky?
No. Kentucky has no state handyman license. However, a handyman may need a local business license or contractor registration depending on the city or county, and cannot legally perform work reserved for a licensed trade – such as electrical (KRS 227A), plumbing (KRS 318) or HVAC (KRS 198B) work – which must be done by a state-licensed contractor.
Who licenses plumbers, electricians and HVAC in Kentucky?
All three are licensed by the Department of Housing, Buildings & Construction (HBC) through its divisions: the Division of Plumbing under KRS 318, the Electrical Division under KRS 227A (815 KAR 35:060), and the HVAC Division under KRS 198B.650–198B.740 (815 KAR 8:010). You can verify a license through the HBC public portal.
