Plumbing License Requirements by State: Journeyman, Master and Contractor Rules
By BRIX Editorial Team · Updated
Plumbing licenses are issued by states, and sometimes counties. Texas licenses apprentices through master plumbers statewide; Florida licenses contractors and leaves journeymen to counties; California licenses only C-36 contractors; North Carolina licenses contractors and technicians. Journeyman-level licenses usually take 8,000 to 12,000 hours where they exist.
Key takeaways
- Texas runs the full ladder statewide: apprentice, tradesman, journeyman (8,000 hours), master and Responsible Master Plumber.
- Florida journeyman plumbers are licensed by counties and cities, with a 12,000-hour or apprenticeship minimum set in state law.
- California has no journeyman plumber license; CSLB says journey-level workers don't hold a license.
- North Carolina licenses plumbing contractors (Class I or II, 4,000 hours) and technicians who work under them.
- CE ranges from 6 hours a year in Texas to none in North Carolina.
How does plumbing licensing work?
Plumbing touches drinking water and sewer gas, so nearly every state regulates it, but they regulate different people. Some license the worker at each level. Others license only the contractor who sells the job and let the contractor's license cover the crew. A few leave the worker licenses to local governments. Before you plan your hours, find which model your state uses.
Plumbing licensing compared by state
| State | Who licenses | Journeyman-level license | Contractor or business license | Exam notes | Continuing education |
|---|---|---|---|---|---|
| Texas | TSBPE (TSBPE) | Statewide journeyman: 8,000 hours + 48-hour course (TSBPE) | Responsible Master Plumber, $300,000 liability insurance (TSBPE) | Master exam at Pearson VUE ($128.50) | 6 hours yearly (TSBPE) |
| Florida | DBPR CILB (contractors) (CILB) | County or city license; state minimum 12,000 hours or apprenticeship, 75% exam (Fla. Stat. 489.1455) | Certified plumbing contractor, statewide (CILB) | Paper exam in Orlando with 5 isometric drawings (DBPR) | 14 hours every 2 years (CILB) |
| California | CSLB (CSLB) | None: a journey-level worker "does not have a license" (CSLB) | C-36 Plumbing contractor, four full years of experience (CSLB) | Closed book (C-36 guide) | No CE on the CSLB pages we checked |
| North Carolina | PHFS board (board) | Technician license, 2,500–3,000 hours (board) | Plumbing contractor Class I or II, 4,000 hours (G.S. 87-21) | PSI, computer-based (FAQ) | None since 2012 (FAQ) |
Which states license journeyman plumbers?
Texas does, statewide, after 8,000 hours and a 48-hour approved course (TSBPE). Florida authorizes counties and cities to issue journeyman plumbing licenses and makes other Florida localities recognize them (Fla. Stat. 489.1455). North Carolina's nearest equivalent is the technician license for people working under a licensed contractor (board). California has none at all; CSLB says a journey-level person "does not have a license" and works under a C-36 contractor (CSLB).
How long does it take to become a plumber?
Typically four to six years to reach journeyman-level independence, and more to run your own shop. Texas puts journeyman at 8,000 hours; Florida's statutory floor for a county journeyman license is 12,000 hours of on-the-job training unless you complete a state-approved apprenticeship; California's CSLB notes a plumbing apprenticeship normally runs five years (CSLB). North Carolina is the shortest road to a contractor license on this page at 4,000 hours, though it's a business license with an exam on code and business practice.
What specialty plumbing licenses and endorsements exist?
Beyond the main ladder, states carve out specialty work. Texas offers three endorsements to masters, journeymen and inspectors, each with a 24-hour approved course: Medical Gas Piping Installation, Multipurpose Residential Fire Protection Sprinkler Specialist and Water Supply Protection Specialist. North Carolina's board issues separate Fuel Piping Contractor (2,000 hours) and Restricted Limited Plumbing Contractor (1,500 hours) licenses, and a Residential Fire Sprinkler Installation Contractor license for plumbing contractors licensed at least two years who take a 16-hour course (board). In California, heat pump water heaters can be installed under either a C-36 plumbing or a C-20 HVAC license. If a specialty brings in steady work, the extra credential often pays for itself on the first few jobs, and it's a line on your website that most competitors can't claim.
What does it take to run your own plumbing company?
- Texas: a master plumber with the Responsible Master Plumber designation, who pulls permits and can serve only one company at a time.
- Florida: a certified (statewide) or registered (local) plumbing contractor license, with credit checks and liability insurance.
- California: a C-36 contractor license and a $25,000 bond; see also California contractor licensing.
- North Carolina: a Class I or Class II plumbing contractor license at $150 a year.
- Everywhere: set up phones, pricing and invoicing before the first emergency call. Start with how to start a plumbing business and the plumbing trade guide.

Frequently asked questions
Do all states license journeyman plumbers?
No. Texas licenses journeymen statewide through TSBPE, Florida leaves journeyman licenses to counties and cities, and California has no journeyman plumbing license at all. North Carolina licenses technicians who work under a licensed contractor instead.
How many hours does it take to become a journeyman plumber?
Texas requires 8,000 hours plus a 48-hour approved course. Florida law sets a minimum of 12,000 hours of on-the-job training, or a state-approved apprenticeship, for county journeyman licenses. Other states set their own numbers.
Can I work as a plumber in California without a license?
Yes, as an employee of a licensed C-36 contractor. CSLB says journey-level workers don't hold a license and can't contract jobs that need a permit, use employees, or exceed $1,000. To contract on your own you need a C-36 license.
What is a Responsible Master Plumber?
It's a Texas designation for the master plumber a plumbing company works under. The RMP supervises the work, pulls permits, must carry at least $300,000 of commercial liability insurance, and can serve only one company at a time.
Do plumbers need continuing education?
It depends on the state. Texas requires 6 hours every year for all TSBPE licensees, Florida CILB contractors need 14 hours every two years, and North Carolina dropped its CE requirement at the end of 2012.
