What starting a Kentucky contracting business actually involves
DHBC's license list is specific, and general contracting isn't on it. The department licenses or certifies plumbers, electricians, boiler contractors, sprinkler and/or fire alarm contractors, and building inspectors. If your work falls outside those categories, a state license through DHBC isn't the mechanism that applies to you.
Plumbing licensing has two tiers with real experience requirements behind each. A journeyman plumber license needs either two consecutive years as an apprentice plumber, or a department-approved plumbing course plus one year as an apprentice - then passing the exam with a minimum of 75 percent on each portion. The application fee is $60, renewed annually at $60.
Master plumber is a meaningfully higher bar, with several qualifying paths. You need two years holding a valid journeyman license (within the past five years) plus two years working under a licensed master plumber's supervision - or one of several alternate paths, including a Kentucky engineer license with sufficient mechanical engineering experience, an out-of-state plumbing license held for two years, or four consecutive years practicing as a master plumber in a state with no licensing requirement. The master exam requires a minimum of 80 percent on each portion. The application fee is $250, renewed annually at $250, and master plumbers specifically have to show insurance documentation at renewal.
Both plumbing tiers require ongoing continuing education, not just an initial exam. Renewal for either license requires proof of continuing education completed, along with the renewal application itself.
Where people get stuck
The mistake is looking for a Kentucky "contractor license" that doesn't exist as a single credential. What actually governs you is whichever specific trade license applies to your work - plumbing, electrical, boiler, or sprinkler/fire alarm - each with its own exam, experience path, and fee schedule.

Does Kentucky require a general contractor license?
No. The Kentucky Department of Housing, Buildings and Construction (DHBC) licenses or certifies specific trades - plumbers, electricians, boiler contractors, sprinkler and fire alarm contractors, and building inspectors - but does not issue a general contractor license.
