Contractor licensing

Kentucky contractor license requirements

Kentucky does not license general contractors statewide. The Department of Housing, Buildings and Construction (HBC) licenses the mechanical trades: HVAC, plumbing, electrical, boiler, and fire sprinkler and alarm contractors.

Kentucky has no statewide general contractor license. The state agency that regulates construction, the Department of Housing, Buildings and Construction (HBC), describes its licensing job as covering plumbers, electricians, boiler contractors, sprinkler and fire alarm contractors, and building inspectors, plus HVAC contractors through its HVAC Division. General contractors, remodelers, roofers, and framers are not on that list. If you run a general contracting company, your licensing questions go to the city or county where you build. If you self-perform HVAC, plumbing, or electrical work, you need a state license, and Kentucky's permit system is built so only licensed people can pull those permits.

General contractors: local rules, state code

Without a state GC license, two things still apply statewide. First, the building code. HBC's building code pages list the 2018 Kentucky Building Code and the 2018 Kentucky Residential Code, which are built on the International Codes with Kentucky amendments. Check HBC's site for the edition in force when you permit a job. HBC's Division of Building Code Enforcement reviews plans and inspects new construction, additions, alterations, renovations, and changes of occupancy. Second, every mechanical trade on your job has to be licensed by the state, which affects how you buy out the work.

Local governments can add their own contractor licensing, registration, or bonding. Before you bid in a new city or county, call the local building permit office and ask three things: does it license or register general contractors, what insurance certificate does it want on file, and who pulls permits for each trade. Then put the answers in your preconstruction checklist so the next estimator does not have to ask again.

HVAC contractor licensing

Kentucky has required heating and air conditioning contractors to be licensed by HBC's Division of HVAC since July 1995, under KRS 198B.650 to 198B.689. On January 1, 2011, Kentucky became the first state to run a statewide HVAC permitting and inspection program for residential and commercial construction. A permit is required for all new construction, and only properly licensed or authorized individuals can apply for one. HVAC contractors now buy permits through HBC's SmartGov portal.

  • Journeyman exam: $50. Bring the 2009 National Fuel Gas Code and the 2015 International Residential Code.
  • Master exam: $150. Bring the 2009 National Fuel Gas Code and the 2015 International Mechanical Code.
  • Both exams are open book, with no official study guide. You register by mailing the exam registration form, fee (payable to the Kentucky State Treasurer), and a 2x2 passport-style photo to HBC's main office.
  • Exams are held regionally, scheduled based on application volume, and results come by mail.

Licensed HVAC contractors and journeymen also keep up with continuing education. Some local governments run their own HVAC programs, and HBC publishes a list of local HVAC jurisdictions. Starting a mechanical shop? See how to start an HVAC business.

Plumbing licensing and permits

Under KRS Chapter 318, HBC's Division of Plumbing examines and licenses master and journeyman plumbers, reviews plans for buildings that serve the public, issues permits, and inspects installations. No one may install or alter plumbing without first getting a plumbing permit, and permits go only to licensed master plumbers or to homeowners working on their own homes. All other plumbing must be installed by a licensed journeyman working under a licensed master.

Permit fees in effect since March 1, 2022 are a $50 base fee plus $14 per opening for one- and two-family residential work, $50 for a water heater only permit, and a $50 base plus $20 per opening for commercial and medical gas work. Say a plumbing sub roughs in a new house with 20 openings: the permit runs $50 plus $280, or $330. Build that into the bid instead of eating it.

Electrical, boiler, and fire protection

HBC's Electrical Division licenses electricians and electrical contractors, certifies electrical inspectors, and inspects state-owned and state-leased buildings. Electrical permits run through the SmartGov portal. HBC also licenses boiler contractors and sprinkler and fire alarm contractors. As the GC, collect each trade's license number with its certificate of insurance before the sub mobilizes.

Kentucky contractor license lookup

HBC's License Search and Verification tool covers building inspector, electrical, electrical inspection, manufactured housing, HVAC, plumbing, and fire licensees. Other licenses are searched through the state's JO Portal. For licensing questions, call HBC's main office at (502) 573-0365. Smart Business Automator stores each sub's state license number, expiration, and insurance by job, so an expired master license shows before inspection day; see subcontractor compliance automation. For payment protection, read Kentucky mechanics lien rules.
