KEY FACTS — IDAHO
Switching Into Plumber Work in Idaho
Real talk — plumbing is one of those trades where the demand never stops, and Idaho is no exception. Every home, every business, every building needs water in and waste out. That's job security you can count on.
If you're an adult thinking about a career change — maybe you're in your late 20s, 30s, or even 40s — apprenticeships don't have age limits. What matters is whether the pay timeline, licensing path, and local market in Idaho make the switch financially survivable. That's what this page is for.
Idaho is one of the fastest-growing states for trade careers. Between new construction, renovation work, and the tech expansion, agriculture, residential boom sectors, plumbers here stay fully booked.
What You'll Earn as a Plumber in Idaho
Money talks, so let's start there. Plumber pay in Idaho breaks down like this:
- Entry-level / Apprentice: $17–$21/hr, or roughly $40K per year. That's money in your pocket from day one — no student loans, no tuition.
- Mid-career / Journeyman: $27–$33/hr, putting you at $60K annually. This is where most plumbers hit their stride.
- Experienced / Master: $41–$49/hr or more, with annual earnings of $92K+. Top performers in Boise and Meridian can push well beyond this range.
How to Get Started in Idaho
Here's the roadmap for becoming a plumber in Idaho:
- Research programs: Idaho has an estimated 6+ active plumber apprenticeship programs. Start with your local UA chapter and programs listed on Prentice, your state's Department of Labor website, and local community colleges.
- Meet the basics: Most programs require a high school diploma or GED, a valid driver's license, and the ability to pass a drug test. You typically need to be at least 18.
- Apply during open windows: Many apprenticeship programs in Idaho accept applications during specific windows — UA programs typically open once or twice a year. Apply to multiple programs to maximize your chances.
- Prepare for assessments: Most programs include an aptitude test and interview. Basic math, mechanical reasoning, and a professional attitude will carry you far.
- Start earning immediately: Once accepted, you're on the payroll from day one. Your 4-5-year apprenticeship combines paid on-the-job training with classroom instruction.
Licensing and Certification in Idaho
Licensing and eligibility rules vary by credential, employer, municipality, and state board. Verify current requirements with the official licensing authority before you apply. Getting certified anyway (through your apprenticeship completion or voluntary certifications) makes you more competitive and portable.
Union vs. Non-Union in Idaho
Idaho is primarily a non-union market, which means more flexibility in choosing employers but you'll need to be more proactive about negotiating your pay and benefits.
Whether you go union (UA) or non-union in Idaho, both paths lead to solid careers. Union programs tend to offer better benefits and higher wages; non-union programs often offer faster entry and more flexibility. Research both options in your area.

Switching Careers: Can You Afford the Transition in Idaho?
The question most adults need answered first: can you survive financially during the apprenticeship? Here's the honest math for Idaho.
A first-year plumber apprentice in Idaho earns roughly $40K per year. That's livable for many households, especially if you have a working partner or some savings to bridge the gap.
By year two, you're looking at $46K. By year three or four, you're often earning more than whatever you left behind — and you're building toward $92K or more without a dollar of student debt.
The key question isn't whether the long-term math works — it often does. The question is whether your household can absorb 12–18 months of lower income while you ramp up. If the answer is yes, or close to yes, the trade-switch decision gets a lot simpler.
