Arizona contractor licenses come in classifications, and the right one depends on what you’re building. Here’s how to match the ROC class to your Scottsdale project.
| Class | What it covers | Best for |
|---|---|---|
| B | General Residential Contractor | New homes, additions, whole-home projects |
| KB-1 | Dual Building Contractor | Custom / luxury home builders |
| KB-2 | Dual Residential & Small Commercial | Builders doing residential + small commercial |
| B-3 | General Remodeling & Repair | Kitchens, baths, renovations, repairs |
| B-1 | General Commercial Contractor | Commercial / tenant improvement work |
New construction: B or KB-1
If you’re building a new house, you want a contractor licensed to build homes from the ground up — most commonly a B General Residential Contractor or a KB-1 Dual Building Contractor. Browse licensed general contractors and custom home builders in Scottsdale.
Remodels and repairs: B-3
Kitchen and bathroom remodels, renovations, and repair work commonly fall under B-3 General Remodeling and Repair. Many full-service builders carry a B or KB class and also handle remodels. See remodeling contractors.
Luxury and mixed residential/commercial: KB-2
For higher-end builds or projects that mix residential and small commercial scope, KB-2 Dual Residential and Small Commercial is common. Browse these builders.

Frequently Asked Questions
What ROC license do I need for a custom home in Scottsdale?
New custom homes are typically built by contractors holding a B General Residential Contractor license or a KB-1 Dual Building Contractor license. Confirm the specific classification on the AZ ROC record.
What license does a remodeler need in Arizona?
General remodeling and repair work is commonly performed under a B-3 General Remodeling and Repair Contractor license, though many full-service builders also hold a B or KB classification.
What is the difference between B and KB licenses?
A “B” classification is a residential contracting license. “KB” (dual) classifications allow a contractor to act as both a residential and, depending on the class, small commercial contractor — KB-1 (building) and KB-2 (residential and small commercial) are common.
Does the license class really matter for my project?
Yes. A contractor must hold a classification that covers the work you’re hiring for. Matching the class to the project is one of the easiest ways to filter out contractors who aren’t a fit.
