License classes in Arizona
Arizona 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:
- C-37 Plumbing — commercial plumbing contractor
- R-37R Plumbing — residential plumbing contractor
- CR-37 Plumbing — dual license covering both commercial C-37 and residential R-37R scopes
- Qualifying Party — the individual whose experience and exams qualify the licensed entity
Experience and training
4 years of supervisory or journeyman-level plumbing experience for the qualifying party; up to 2 years may be credited from technical training
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
PSI administers the C-37/CR-37 trade examination; the qualifying party must also complete the ROC Statutes & Rules course and exam (SRE), unless eligible for a waiver
Renewal and continuing education
Biennial — ROC contractor licenses are issued and renewed on a two-year cycle (A.R.S. § 32-1123.01, staggered periods of licensure); no state continuing education requirement for the trade license
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
A license bond must be posted before licensure, ranging from $4,250 to $100,000 depending on classification and estimated annual volume; it may be posted as cash, a certificate of deposit, or a surety bond
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 Arizona. 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
Arizona does not issue individual journeyman or master plumber licenses at the state level — licensing is contractor-based and attaches to a business entity through a Qualifying Party. Individual journeyman certification, where required at all, is handled by local jurisdictions, and city permits are still issued locally.
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.
