Kentucky Trade Licenses: Electrician, Plumber and HVAC License Requirements, Fees and Insurance from DHBC
Kentucky Trade Licenses: Electrician, Plumber and HVAC License Requirements, Fees and Insurance from DHBC
If you plan to wire buildings, install plumbing or service heating and cooling systems in Kentucky, you will deal with the Department of Housing, Buildings and Construction (DHBC). This guide covers what DHBC requires for electrician, plumbing and HVAC licenses, what each license costs, the insurance you must carry, and the local rules that still apply after you hold a state license.
Disclaimer: This is informational content, not legal or tax advice. Fees, hours, renewal rules and code editions change. Confirm every figure with DHBC at dhbc.ky.gov before you apply or pay.
How Kentucky Licenses Trades
Kentucky does not have a general statewide business license. Forming an LLC or corporation, or registering an assumed name, is a filing with the Secretary of State, not a license. Those filings go through the Kentucky One Stop Business Portal for new formations, and through FastTrack Online Filings for annual reports, assumed names and registered agent changes.
Licensing happens by agency and by trade. DHBC licenses electricians, plumbers and HVAC contractors and technicians. Other state bodies license other fields. The Real Estate Authority covers real estate, the Boards of Cosmetology and Barbering cover those trades, the Cabinet for Health and Family Services covers child care and home health, ABC covers alcohol and tobacco, and local health departments issue food permits.
Kentucky also has no statewide general contractor license. If your work is construction but falls outside DHBC's three trades, you will not get a state general contractor license. Check the city and county where you work for their own contractor licensing rules.
A state license from DHBC replaces local licensing of that same trade. Local zoning rules, permits and occupational license taxes still apply, so a DHBC license alone does not clear you to work in every city or county.
Electrician Licenses
Electrical licensing falls under KRS Chapter 227A and 815 KAR 35:060. There are three license levels: electrical contractor, master electrician and electrician. Each is a biennial license, which means it runs for two years. The two-year cycle has applied since July 15, 2024.
| License | Fee (biennial) | Experience required | Insurance |
|---|---|---|---|
| Electrical contractor | $400 | Confirm with DHBC | $1,000,000 liability |
| Master electrician | $200 | 16,000 hours | Confirm with DHBC |
| Electrician | $100 | 8,000 hours | Confirm with DHBC |
Experience hours are the number most applicants get wrong. A master electrician needs 16,000 hours and an electrician needs 8,000. Keep dated records of your work now, with employer names, job types and hours, because reconstructing them later is slow. The electrical contractor license carries the heaviest insurance requirement in this group: $1,000,000 in liability coverage.
Continuing education is also part of the cycle. The electrical rules call for 6 continuing education hours a year. Confirm how that applies to the specific license you hold, since the requirement may differ by license level.
Plumbing Licenses
Plumbing licensing falls under KRS Chapter 318 and 815 KAR 20:030. Plumbing licenses are annual. Each one expires on the last day of the licensee's birth month, so calendar your own date rather than a shared state deadline.
| License | Fee (annual) | Insurance |
|---|---|---|
| Master plumber | $250 | $250,000 liability |
| Journeyman plumber | $60 | Confirm with DHBC |
The master plumber must carry $250,000 in liability coverage. Farmsteads are exempt from these plumbing requirements. Because the exemption has limits, confirm with DHBC how it applies to your property and your work before you rely on it.
HVAC Licenses
HVAC licensing falls under KRS 198B.650 to 198B.689 and 815 KAR 8:010. Both HVAC license levels are annual.
| License | Fee (annual) | Insurance |
|---|---|---|
| Master HVAC | $250 | $500,000 general liability plus $300,000 property damage |
| Journeyman HVAC | $50 | Confirm with DHBC |
The insurance requirement for HVAC is set out in KRS 198B.668. Carry $500,000 in general liability coverage and $300,000 in property damage insurance. Ask your insurer for a certificate that shows both limits, then confirm with DHBC which proof of insurance it accepts.
Searches for a kentucky hvac license usually lead to the master and journeyman levels above. Those are the two that matter for most technicians and small shops. If you run a company that does both HVAC and electrical work, you need the license for each trade, not one license that covers both.
Insurance Requirements at a Glance
| Trade | License | Required insurance |
|---|---|---|
| Electrical | Electrical contractor | $1,000,000 liability |
| Plumbing | Master plumber | $250,000 liability |
| HVAC | Master and journeyman | $500,000 general liability and $300,000 property damage |
Get insurance quotes before you calculate your total startup cost, because the required coverage is a recurring expense on top of the license fee.
Fees to Confirm With DHBC
DHBC also issues boiler, sprinkler, elevator and building inspector licenses. This guide does not list fees for those licenses. Call DHBC at (502) 573-0365 and ask for the current fee, the renewal period and any experience requirement before you budget for them.
Code Edition You Must Follow
Kentucky enforces the 2023 National Electrical Code (NEC). DHBC began reviewing the 2026 NEC in March 2026 through a task force. Because a new edition may be adopted, check dhbc.ky.gov for the code edition in force before you quote a job or pull a permit.
Local Rules and Business Taxes
A state license does not end your local obligations. Four items commonly catch new tradespeople off guard.
- Local occupational license taxes. Cities, counties and school districts levy these taxes on payroll, net profits or gross receipts. Kentucky has 120 counties and about 420 cities, and each runs its own forms and revenue office. Check the occupational license tax district for every city and county where you work.
- Sales tax. Kentucky's sales tax is a flat 6% with no local sales taxes, but it reaches about 50 services. Ask the Department of Revenue at revenue.ky.gov whether your service invoices are taxable before you set your rates.
- Entity tax. Kentucky has no franchise tax, but LLCs and corporations owe the Limited Liability Entity Tax (LLET), which has a $175 minimum if Kentucky gross receipts or gross profits are $3 million or less. An LLC's income passes through to its members and is taxed at the 3.5% flat individual rate for 2026.
- Annual report. LLCs and corporations file a $15 annual report due June 30 each year. The filing window opens January 1. A domestic entity that misses June 30 is administratively dissolved.
Steps to Get Licensed
- Choose your trade and license level. Match your experience to the level you can document. Master electrician requires 16,000 hours and electrician requires 8,000.
- Document your experience. Keep dated records of employers, job types and hours from the start.
- Buy the required insurance. Electrical contractors need $1,000,000 in liability coverage, master plumbers need $250,000, and HVAC licensees need $500,000 in general liability plus $300,000 in property damage coverage.
- Confirm the fee and renewal date. Electrical licenses renew every two years. Plumbing and HVAC licenses are annual, and plumbing licenses expire on the last day of your birth month.
- Check local requirements. Confirm occupational license tax registration, zoning and permit rules for each city and county where you will work.
- Form your entity if you need one. An LLC files Articles of Organization (Form KLC) for a $40 filing fee. A corporation files Articles of Incorporation (Form PAI) for a $50 filing fee. The name must include "limited liability company," "limited company," "LLC" or "LC". Then calendar the $15 annual report due June 30. File online through the Kentucky One Stop Business Portal.
Where to Get Help
Start with DHBC for license questions, since it is the only agency that can confirm the current fee, hours and code rules for your trade. The Kentucky Secretary of State, Division of Business Filings handles entity filings and assumed names. For help with the business side of your plans, the Kentucky Small Business Development Center (KSBDC) offers free advising to small businesses.
If your operation combines several trades, has employees in more than one county, or involves a partner or investor, talk with a qualified attorney and a CPA before you form the business or sign contracts. This guide is informational only and does not replace advice tailored to your situation.
