License classes in Idaho
Idaho issues the following classes. Getting the class right matters — several states have residential-only or limited-scope licenses that will not cover commercial or multifamily work:
- Plumbing Apprentice — learns and assists; may not perform plumbing work except under a journeyman's supervision (Idaho Code Title 54, Chapter 26)
- Plumbing Journeyman — installs, alters and extends plumbing systems while employed by and under the direction of a plumbing contractor
- Plumbing Contractor — may offer and assume work on a contract basis and direct qualified employees
- Specialty Apprentice / Specialty Journeyman / Specialty Contractor — restricted to the specialty classification for which the person is certified
Experience and training
We could not find a published hour requirement for Idaho that we were willing to state as fact, so we have left it blank rather than guess. Ask Idaho Division of Occupational and Professional Licenses (DOPL) — Idaho Plumbing Board for the current experience requirement in writing, and ask specifically whether classroom or trade-school hours can offset field hours — that substitution is where most of the variation between states lives.
One thing worth knowing regardless of state: the hours only count if they were logged properly at the time. Several boards require you to register as an apprentice before the clock starts, and hours worked while unregistered are simply gone. If you are early in the trade, get the registration paperwork right now rather than reconstructing it four years later.
The exam
Confirm the current testing vendor with Idaho Division of Occupational and Professional Licenses (DOPL) — Idaho Plumbing Board. States move between PSI, Prov and Pearson VUE periodically, and study material bought for the previous vendor is often the wrong format.
Renewal and continuing education
Historically a three-year license term. DOPL has announced a transition to a two-year renewal cycle beginning April 1, 2026, with individual licenses expiring on the licensee's birthday and business licenses on the original issue date. Continuing education requirement — verify with the board, as sources conflict.
Letting a license lapse is more expensive than it looks. Some states allow a short grace period with a penalty fee; others treat a lapsed license as forfeited and make you retest from scratch. Put the renewal date in your calendar with a 90-day warning, not a 7-day one.
Insurance and bonding
We could not verify a published state bond or insurance minimum for Idaho. That does not mean you should work uninsured — local permit offices, general contractors and property managers routinely require a certificate regardless of what the state demands.
Separately from whatever the state requires: Pipe Well requires every plumber on the network to carry current general liability insurance and to upload the certificate before the first appointment is sent.
Working across state lines
We could not confirm any published reciprocity agreement for Idaho. That does not always mean there is none — several states evaluate out-of-state licenses case by case, or let you sit for the exam on the strength of a license held elsewhere. If you are relocating, call the board and ask specifically about endorsement or credential review rather than assuming you start over.
What plumbers actually get wrong here
Idaho plumbing licensing moved out of the old Division of Building Safety and now sits with the Division of Occupational and Professional Licenses, so older forms, fee schedules and DBS web links circulating online are obsolete — always start at dopl.idaho.gov. DOPL is mid-transition to a two-year renewal cycle keyed to the licensee's birthday, which means a newly issued license may be prorated and your first Idaho renewal notice may arrive on an unfamiliar schedule. Idaho also licenses a full parallel ladder of specialty apprentice/journeyman/contractor classifications, so work such as certain fuel gas or restricted-scope installations is licensed separately rather than being folded into the general plumbing license. Several widely-cited third-party sites disagree with each other on Idaho's hour and continuing education requirements — confirm current numbers with DOPL before you rely on them.
Once you are licensed: getting the work
A license gets you legal. It does not get you a full schedule. The usual next step is buying leads — $40 to $85 for a contact that three or four other shops bought at the same moment, which at a realistic 10–20% close rate works out to somewhere between $300 and $1,000 for every job you actually book, plus the unpaid hours spent chasing the ones that go nowhere.
Pipe Well works the other way round. We book appointments, not leads, and we handle everything up to the moment you knock on the door: the advertising, the phone call, qualifying the job, getting the address and access details, and agreeing a date and time window with the homeowner. What reaches your phone is a scheduled appointment — name, address, time window and what is wrong. You reply YES and it is yours.
What it costs
Nothing to join. No subscription, no per-lead charge. You do the job, you set your own price, and you collect payment from the customer directly. Then Pipe Well is paid 50% of the job after your documented materials come off the top:
(amount collected − documented materials) × 50%
| Collected | Materials | Net | Pipe Well | You keep |
|---|---|---|---|---|
| $400 | $40 | $360 | $180 | $220 |
| $1,200 | $520 | $680 | $340 | $860 |
| $2,800 | $800 | $2,000 | $1,000 | $1,800 |
| $8,500 | $3,200 | $5,300 | $2,650 | $5,850 |
Due within 48 hours of the customer paying you. If they never pay, you owe nothing. And look honestly at that last row — on a big repipe our share is a large number. If your book is already full of $8,500 jobs you are better off filling that capacity yourself. We are worth most to a shop with open capacity it cannot currently fill.
