Journeyman Plumber: Requirements, Pay, and Career Path

A journeyman plumber is a state-licensed tradesperson who has finished an apprenticeship and passed a licensing exam, so they can install, repair, and service plumbing on their own without supervision. It is the middle rung of the trade, above apprentice and below master. Reaching it usually takes about four to five years and roughly 8,000 supervised hours.

What is a journeyman plumber?

A journeyman plumber holds a state or local license that authorizes independent trade work: running service calls, installing supply and drain systems, and connecting fixtures and gas lines without a supervisor watching. The credential proves competence but stops short of business authority. In most states a journeyman still cannot pull permits or run a shop in their own name.

The word “journeyman” comes from the old guild system, where it marked the tradesperson who could travel and work for daily wages after finishing an apprenticeship. In modern US plumbing, the license is the proof. Boards like the Texas State Board of Plumbing Examiners (TSBPE) and state agencies in Michigan, Massachusetts, and Maryland issue it, and the exact title (journeyman, journey-level, or journeyperson) varies by state.

Apprentice vs. journeyman vs. master: the plumbing license ladder

Plumbing licenses climb three rungs: apprentice, journeyman, then master. Each rung adds authority and requires more hours plus another exam. An apprentice trains under supervision, a journeyman works independently, and a master can design systems, pull permits, and qualify a business. The table below shows what each level can do, who supervises them, and typical pay.

The ladder is a supervision ratio in practice. Many states cap how many apprentices one journeyman may oversee, often at a 1-to-1 or 3-to-1 ratio, and require a master on staff for a company to hold its license. That structure is why the master tier matters far beyond the pay bump: it is the license a business is built on.

How do you become a journeyman plumber?

Becoming a journeyman plumber follows one path in most states: finish high school, enter a registered apprenticeship, log the required supervised hours (commonly around 8,000 over four to five years), complete related classroom instruction, then pass the state journeyman exam. Hour counts and exam rules vary by state, so confirm the numbers with your state plumbing board first.

1. Get a high school diploma or GED. You usually must be at least 18 to hold an apprentice registration or join a union local.
2. Enter a registered apprenticeship. Through a union (UA local), a PHCC or ABC chapter, or a service company. This is a paid job, not tuition.
3. Log the supervised hours. Roughly 6,000 to 8,000 on-the-job hours, tracked and signed by a licensed plumber, over about four to five years.
4. Complete related classroom instruction. Often 144+ hours a year covering code, math, safety, and blueprint reading, at a trade school or apprenticeship program.
5. Apply and pass the journeyman exam. A written test on your state and local code, plus practical plumbing knowledge.
6. Pay the fee and receive your license. Then renew it on your state’s cycle, often with continuing education.

Two routes feed the apprenticeship. Most people earn while they learn on the job, which is the full path to become a plumber covered hour by hour and state by state. Others start with a classroom credential first: plumbing trade school programs can shorten the hour requirement in some states and count toward the classroom side. Either way, you still need the supervised field hours and the exam.

What can a journeyman plumber do, and what can’t they do?

A journeyman can work unsupervised, install and repair full plumbing and gas systems, and often supervise apprentices (many states cap the ratio, sometimes at three per journeyman). What they usually cannot do: pull permits in their own name, legally contract as a business, or sign off as the qualifying license for a shop. That authority belongs to a master.

In day-to-day terms, a journeyman runs the truck. They diagnose, quote within the shop’s pricing, replace water heaters, repipe, clear and repair drains, and set fixtures, all without a master standing over them. The line they cannot cross is the business and permit line. If you want to advertise, pull permits, and bill customers under your own name, you generally need to upgrade to master and register a company, which is the first hurdle to start a plumbing business.

How much does a journeyman plumber make?

A journeyman plumber typically earns about $59,000 to $70,000 a year in 2026, or roughly $28 to $34 an hour, though union shops and high-cost metros push well past that. Pay tracks local demand, union status, and overtime more than raw skill. Apprentices earn less on a step scale; masters and owners earn more.

The spread is wide because the label is used loosely across salary sites and regions. Union journeymen in New York City, San Jose, and Chicago can clear $50 an hour before benefits, while non-union rural markets sit closer to $25. For the full breakdown, including plumber earnings by level and state, look at median wage plus overtime and benefits together, since a strong benefits package can be worth another 20 to 30 percent on top of the hourly number.

Does a journeyman plumber license transfer between states?

Sometimes. Plumbing licenses are issued by states (and some cities), so a journeyman license does not automatically transfer. Many states hold reciprocity agreements that waive the exam if your home state’s hours and standards match theirs. A state requiring 8,000 hours will not reciprocate with one requiring 4,000. Check both boards before you plan a move.

Reciprocity tends to favor the journeyman tier over the master tier, and the deals are specific. Arkansas and Texas reciprocate journeyman licenses directly; Idaho grants reciprocity to journeymen from Montana, Oregon, and Washington. Even where a deal exists, you often must have held the license in good standing for at least a year, pay a fee, and pass the new state’s plumbing law exam. If no agreement exists, you may have to document your hours and test again from scratch.

Frequently asked questions

What is the difference between a journeyman and a master plumber?

A journeyman works the trade independently but cannot pull permits or run a plumbing company in their own name. A master plumber can: after roughly five more years and another exam, a master designs systems, obtains permits, and qualifies a business under their license. Every plumbing shop needs at least one master to operate legally in most states.

How long does it take to become a journeyman plumber?

Usually four to five years. Most states require a registered apprenticeship of roughly 6,000 to 8,000 supervised hours plus related classroom instruction before you can sit the journeyman exam. Michigan accepts about 6,000 hours over three years; Texas requires 8,000. If you finish faster by logging more hours per year, some states still enforce a minimum calendar time.

Can a journeyman plumber pull permits?

In most states, no. Permit authority is tied to the master plumber’s license or a licensed plumbing contractor, not the journeyman. A journeyman can perform the permitted work, but a master usually has to pull and sign for the permit. A few jurisdictions allow journeymen limited permit rights, so check your local building department.

Can a journeyman plumber work for themselves?

Rarely as a full business. In most states you need a master plumber’s license plus a contractor registration to advertise, pull permits, and run a plumbing company in your own name. A journeyman can moonlight on unpermitted repairs where local rules allow, but starting a licensed shop generally means either upgrading to master or partnering with one.

How much does a journeyman plumber make an hour?

Roughly $28 to $34 an hour on average across the country in 2026, which works out to about $59,000 to $70,000 a year full time. Union journeymen in major metros often clear $45 to $55 an hour before benefits and overtime. Rural and non-union markets sit lower. Your local demand and union status move the number most.

Does a journeyman plumber license transfer to another state?

Not automatically. Licensing is state and sometimes city level, so you apply in the new state. Many states have reciprocity: if your home state’s hours and exam match theirs, they waive retesting. Arkansas and Texas reciprocate journeyman licenses; Idaho accepts Montana, Oregon, and Washington journeymen. Others make you retake the law portion. Confirm with the new state’s board.
