To verify a plumber's license in Utah, ask for the plumber's name, license class, and license number, then search for them on the state's Verify a License lookup. Match the name, the class, and the status to the person who will work in your home.
The Utah Division of Professional Licensing (DOPL) issues plumber licenses in five classes: Apprentice, Journeyman, Residential Journeyman, Master, and Residential Master. The check takes about five minutes. A second five-minute call to the Eagle Mountain Building Department tells you whether your job needs a permit.
Five minutes: how to check a license before you sign anything
Ask for the details in writing
Request the plumber's full name, license class, and license number by text or on the written scope of work. Anyone licensed should hand this over without hesitation.
Open the state lookup
Go to the Verify a License lookup on the Utah state site. Search using the name or number you were given.
Compare every field
Check that the name matches, the class fits the work, and the status shows the license as active. A mismatch on any one of those is a reason to pause.
Match the record to the person
On the day of the job, confirm the person at your door is the licensed plumber or a trainee working under one. Ask who is supervising any apprentice.
Utah plumber license classes and what to ask about each
The class on the record tells you what level of training the plumber holds. Use the questions in the right column to turn the label into something useful.
| License class | What the label signals | What to ask |
|---|---|---|
| Apprentice | A trainee learning the trade | Who is the licensed plumber supervising your job? |
| Journeyman | A plumber qualified to work in the trade | Does this class cover the type of building I own? |
| Residential Journeyman | A journeyman license for residential work | Is my project a home, or does it include commercial space? |
| Master | The highest class on the list | Will the master be on site or only name the company? |
| Residential Master | A master license for residential work | Is the person who will do my work covered by this record? |
What the lookup can and cannot tell you
The Verify a License page confirms that the state has a record for a person and shows the class and status. It does not tell you whether the plumber will show up on time, explain things clearly, or price the job fairly. A valid license is a floor, not a ranking.
DOPL also treats the Plumber Red Seal Certification as equivalent to the Utah Journeyman Plumber License. If someone mentions a Red Seal, that is a recognized route, but the same lookup habit applies.
Business names can be confusing, because the license belongs to a person while the truck wears a company logo. Ask which licensed person is responsible for your job.
Questions to ask before you hire, beyond the license
A license check is one item on a short list. Put these questions to every plumber you consider so you can compare answers side by side.
- What is your license class and number, and who will be on site?
- Will you pull the permit, if one is needed, and who schedules the inspection?
- Is there a written price and scope before work starts?
- Can you show proof of liability insurance on request?
- Does the job involve digging, and who calls 811 first?
- What happens if something fails after the work is done?

Eagle Mountain note: ask the city, not the contractor, what needs a permit
The City of Eagle Mountain publishes a sheet of work that requires a permit. It includes water supply piping, drain-waste-vent systems, sewer connections, water heaters, major plumbing repairs, fixture additions and relocations, and new gas piping, extensions, or meter work, unless specifically exempted.
Many minor repairs and ordinary maintenance can be exempt. Permit rules vary, so ask the Eagle Mountain Building Department at 3267 E Campus Dr, Suite H, or call 801-789-6614 with your exact job in hand.
Six warning signs when you ask about licensing
Most good plumbers answer these questions easily. Trouble in the answers is worth taking seriously.
Vague answers about the license
A plumber who cannot say the class or number may not hold one. Move on if the answer never gets clearer.
The name does not match the record
A record under a different name means you are not looking at the right person. Ask for clarification before work begins.
An expired or inactive status
An inactive record can have a simple explanation, such as a late renewal. Do not hire until it is fixed.
No written scope or price
A handshake price leaves room for extras. Insist on a written scope before work starts.
Pressure to skip the permit
If the work needs a permit, skipping it can leave you with unapproved work you must disclose when you sell.
A request for full payment upfront
Materials may need a deposit, but full payment before the work starts leaves you no bargaining room.
How to read the answer to the permit question
Answers that are reassuring
- It depends on the work, and I will check with the city
- I pull the permit and schedule the inspection
- That repair is minor and likely exempt, but let's confirm
- The Utah-adopted International Plumbing Code sets the standard
Answers that should slow you down
- You never need a permit for that
- We can skip it and save you the hassle
- Don't bother calling the city
- I can't say who is responsible for the inspection
What a permit actually means for your plumbing
A permit puts the work on the city's record and brings an inspector to check it against code. For plumbing, that code is the Utah-adopted International Plumbing Code, which sets rules for supply piping, drains, vents, and fixtures. Inspection catches mistakes that are expensive to fix once drywall closes up.
Permits are not the same as a license. A license describes the person. A permit describes the job. You want both, and the plumber you hire should be comfortable explaining each.
For jobs like a new line, a water heater swap, or an addition, a good plumbing installation contractor will talk about the permit before you ask. A planned water heater installation is a common example of a job where the city's rules matter.
Hiring across town lines
Plumbers often work across several towns, so the permit office changes with the address. A plumber who serves Saratoga Springs, about 10 miles away by estimate, still has to follow Eagle Mountain rules when the home sits in Eagle Mountain.
The license check works the same everywhere in Utah. The Saratoga Springs plumber page shows how one crew can cover both towns while the permit step stays tied to your home address.
Questions readers ask
Where do I look up a plumber's license in Utah?
Use the Division of Professional Licensing's Verify a License lookup on the Utah state site. Search for the name or license number, then check the class and status on the record.
What is the difference between a journeyman and a master plumber?
They are separate license classes issued by DOPL. A master is the higher class, and both have residential versions. Ask the plumber which class applies to your job and who will be on site.
Is a Red Seal plumber the same as a Utah journeyman?
DOPL states that the Plumber Red Seal Certification is considered equivalent to the Utah Journeyman Plumber License. You can still confirm the person's Utah record through the lookup before hiring.
What should I do if the license shows as expired?
Pause the hire and ask the plumber to explain. A late renewal can be fixed quickly, but you should see an active status before work begins. If answers stay vague, call another plumber.
Should I ask a plumber for proof of insurance too?
Yes. A license shows qualification, while insurance covers damage if something goes wrong. Ask for the proof in writing, and for a licensed and insured plumber it is an easy request to meet.
Where do I confirm permit rules for a plumbing job in Eagle Mountain?
Contact the Eagle Mountain Building Department at 801-789-6614 and describe the work. The city's sheet lists many plumbing categories as permit items but exempts some minor repairs. Ask before the job starts and keep a note of who you spoke with.
