the short answer

Arizona splits electrical contracting into three Registrar of Contractors classes: C‑11 for commercial work, R‑11 for residential work, and CR‑11 for both on one license. The C‑11 scope covers electrical work below 600 volts and draws set lines around work in the public right of way.

the Arizona electrical classes.

Every electrical class the ROC licenses, in plain words.

C‑11: Commercial electrical. Installing, altering and repairing wiring and equipment below 600 volts, including outside, overhead and underground work. Public right of way work is limited by the published scope.
R‑11: Residential electrical. Work on homes and what’s attached to them on the property. It’s the residential half of CR‑11.
CR‑11: Dual electrical. The C‑11 commercial and R‑11 residential scopes on one license.
Bond: Required for every class. Residential: $4,250, or $7,500 at $375,000 a year or more. Commercial: $2,500 to $50,000 by yearly volume. A CR‑11 combines both amounts.

what to know before
you bid in Arizona.

Voltage draws the line.
The C‑11 scope stops below 600 volts and limits public right of way work, so the word electrical doesn’t cover every job. Tell us what you install, repair and test so the policy describes the same work.
A bond isn’t insurance.
Your ROC bond is a licensing requirement that protects the public. It isn’t liability insurance, and it doesn’t pay when your work damages a customer’s property.

Straight answers on Arizona electrical licenses.

What electrical license do I need in Arizona?

It depends on where you work. The Arizona Registrar of Contractors licenses electrical contractors under C-11 for commercial work, R-11 for residential work, or CR-11 for both on one license. Each class has its own scope, and the commercial scope stops under a voltage limit, so check the current ROC wording before you bid.

What is the difference between Arizona C-11, R-11 and CR-11?

C-11 is the commercial electrical class, R-11 is the residential class, and CR-11 puts both scopes on one license. The commercial scope has a voltage limit and draws lines around public right of way work, so the word electrical doesn’t cover every project. Tell us what you install, repair or test so the policy matches.

Does my Arizona contractor bond cover damage to a customer’s property?

No. The license bond is a licensing requirement that protects the public under state law, with its own claim rules. It isn’t general liability insurance, which is what responds when your work damages someone’s property or injures them. Your bond amount depends on your license type and yearly volume, so review the bond, the contract and the policy separately.
