Arizona — plumbing code & licensing
Verified
The code
| Code family | none-statewide |
| Edition in force | no statewide edition — adoption is local |
| Effective date | no statewide code — adoption and dates are local |
| Adopted by | None at state level - A.R.S. 34-461 makes public buildings comply with the plumbing codes adopted by the city, town, county or fire district in which the building is located; code adoption is local throughout |
| Adoption source | https://www.azleg.gov/ars/34/00461.htm |
| State amendments | Amendments are a local matter — no state-level set |
Licensing
| Model | State contractor-only licensing: the Registrar of Contractors licenses plumbing contractor BUSINESSES - the license belongs to the business and is held through a qualifying party - in separate commercial (C-37), residential (R-37), and dual commercial/residential (CR-37) plumbing classifications. Arizona issues no state journeyman or apprentice plumber license; some cities license at that level locally |
| Authority | Arizona Registrar of Contractors (ROC) |

Permits & inspections
Permits and inspections are local; under A.R.S. 34-461 public buildings are subject to inspection under the locally adopted codes, and a public building built where no local codes have been adopted follows the codes of the largest city in the county.

Working notes
The ROC's own classifications page (opened) establishes the framework - separate commercial, residential, and dual licenses for each trade, license issued to the business - but its class list renders as an interactive accordion that did not expose the plumbing class codes in text form; the C-37 / R-37 / CR-37 plumbing class codes are as listed for Arizona on the California CSLB's official reciprocal classifications list (cslb.ca.gov, opened). Mirrors the Arizona electrical row in the electrical foundation.
