What Is a CR-37 License in Arizona?

CR-37 License in Arizona

The Arizona Registrar of Contractors (ROC) lists CR-37 as a plumbing classification. It allows the scopes of work permitted under the commercial C-37 Plumbing license and the residential R-37R Plumbing license.^[1]

It is not a garage door or opener license.

The prefix system explains the name. The ROC issues residential, commercial, and dual licenses for particular trades.^[1] R means residential, C means commercial, and CR means dual, covering both. CR-37 is the dual version of the plumbing license.

The residential classification rule, A.A.C. R4-9-103, also names no garage door or garage door opener class.^[2] A company advertising CR-37 for door work is showing you a plumbing credential.

That may be a real license, but it doesn't tell you the company is authorized for your job.

What the ROC Classification Rules Say About Garage Doors

Arizona licenses contractors by classification, and each contractor applies for a specific one.^[5] A license is generally required when labor and materials exceed $1,000 or when a permit is required, regardless of the project price.^[1]

A minor adjustment may fall below that line. A full door replacement or a new opener installation is more likely to cross it.

Because R4-9-103 has no dedicated garage door class, this work may sit under broader residential categories. Which one applies can depend on what the contract covers.^[2]

Opener wiring and electrical work

The rule text doesn't settle whether installing an opener requires an electrical classification. The same goes for whether the ROC assigns a class case by case for this kind of job.

Ask the ROC directly. Then ask the contractor which class they say covers each part of your scope: door, opener, framing, and any wiring.

How to Look Up a Garage Door Contractor's License

The ROC tells consumers to review a contractor's record through its Contractor Search and confirm that the license class allows the work described in the contract.^[3] Here is how to do that in practice.

• Ask for the company's legal name and exact ROC license number before you schedule anything.
• Search either one in the ROC Contractor Search at roc.az.gov and confirm the license is active.
• Read the listed classification, expiration date, bond information, and complaint history.
• Compare the classification against your written estimate, line by line.

Then make one more check. The ROC advises calling the phone number listed on the license to confirm that the person you're dealing with is an authorized representative of that company.^[4]

Don't rely only on the number in the ad.

Pro tip

Call the phone number listed on the ROC record, not the one in the ad, to confirm who you are dealing with.

Be careful with other badges, too. "Licensed, bonded, and insured" in an ad is not a record you can verify. Neither is a manufacturer dealer badge, since dealer status is a business relationship and not a license.

Only the ROC record settles it.

A valid license is a screening step. It doesn't guarantee fair pricing or good workmanship. Ask for an itemized written estimate that separates parts, labor, removal, opener work, and warranty terms.

Confirm liability insurance on its own, too. Arizona doesn't require contractors to carry workers' compensation, and ROC bonds are modest.

Once a company checks out, you can compare options for garage door repair. For a fuller walkthrough of licensing for this trade, see Arizona ROC License for Garage Door Companies Explained.
