Arizona Contractor’s License Board

The issuance of these licenses is handled by the Arizona Registrar of Contractors, which was established in 1931 by the Arizona Legislature. The Registrar not only screens contractor license applicants but they also probe contractor-related complaints and go after these contractors, both licensed and unlicensed, that are being complained about.

All relevant information regarding contractor licensing may be found at their official website, which is https://roc.az.gov. But if you want to go directly to their head office in Phoenix for your contractor-related concerns, you can find their office at 1700 W. Washington St. Suite 105, Phoenix, Arizona 85007-2812. You may also contact them through fax at (602) 542-1599 or phone at (602) 542-1525. The Registrar also has an office in Tucson, which is located at 400 W. Congress St., Ste. 212, Tucson, Arizona 85701-1353. The Tucson office may also be contacted at (520) 628-6345 or (520) 628-6588 for fax. The state’s Registrar of Contractors also has an office in Flagstaff, specifically at 2501 N 4th Street #22, Flagstaff, Arizona 86004-3701. However, you may only go to their Flagstaff office if you have an appointment. If you want to set an appointment to go to the Flagstaff office or have other concerns, you need to do so by calling the Registrar’s hotline at 1-877-692-9762 (or 1-877-MY-AZROC) or send them an email at Licensing@roc.az.gov.

Are you an out-of-state corporation who wishes to do contracting work in Arizona? If so, you also need to make sure that you are authorized to do business in the state. In order to do that, you have to obtain a certification that states that you are authorized to conduct business transactions anywhere in Arizona. You can get this letter by paying a filing fee of $175 to the Arizona Corporation Commission. If you need to personally make inquiries about this requirement, you need to go to their Corporations Division, which you can reach by phone at (602) 542-3026 and is headquartered at 1300 West Washington, Phoenix, AZ 85007.

Contractor License Classifications and Requirements in the State of Arizona

Is the contract of your project worth more than $750? If so, you need to get your contractor license. Each contractor license in Arizona is also classified depending on what kind of projects you are allowed to work on, which are:

  • Residential – limited to working on residential properties and other similar dwellings. Residential contractors of all license types can not only work on standalone houses but also townhouses, cooperative buildings, condominiums, and apartments. But if you will be working on an apartment project, it must only be up to four units max. They can also work on appurtenances connected to or on any residential property, such as meters, sewer and utility line connections, and other related structural or mechanical systems,
  • Commercial – can work on any other private or public building, structure, or property that cannot be considered as residential and regardless of size, and
  • Dual license – allows contractors to work on both residential and commercial projects.

In particular, eight general license classifications exist for contractor licenses in Arizona. These licenses have assigned codes that reflect the specific classification of the license (in the form of a letter) plus the allowed scope of work (represented by a number or left blank). For example, a contractor that has an A-9 license is an engineering contractor that can work on commercial swimming pools. For a full explanation and scope of these licenses, you can check out https://roc.az.gov/license-classifications.

Engineering Contractor (Commercial)

Commercial engineering contractors are further classified into the following categories:

  • General Engineering (A-) – the scope of this license allows the contractor to build or do maintenance works on various public projects and structures.

Why You Should Go and Get Yourself Licensed

Arizona’s Registrar of Contractors is strict when it comes to issuing licenses, and even more so when it comes to going after unlicensed contractors. This is because part of the mandate of the Registrar is to do investigative work on contractors being complained on, both licensed and unlicensed. With the exception of those under the state’s “handyman exception,” which covers contractors who work on certain projects considered minor or casual that have a total cost not exceeding $1,000, any unlicensed contractor will be subjected to fines, or even sentencing for repeat offenders. Fines for unlicensed contractors do not go lower than $1,000 and they may be charged with a Class 1 Misdemeanor, which may lead to you being jailed for up to six months.

The state even has legislation regarding unlicensed contractors, which you can read for yourself at https://www.azleg.gov/viewdocument/?docName=http://www.azleg.gov/ars/32/01121.htm. Not only that, the state also has a wall of shame of sorts for contractors that are unlicensed and have been caught by the Registrar. You can view this online database at https://www.azroc.gov/roc/unlicensedviolations.html and the most wanted list of unlicensed contractors at https://roc.az.gov/roc-wanted. You don’t want to belong to any of these lists, do you?

The Importance of Hiring a Contractor with a License

Horror stories involving unlicensed contractors are quite common and as a homeowner, you do not want to experience that headache. Imagine having to hire a contractor for your contract worth $1,500 but eventually requiring you to shell out an additional $4,000 just to do repairs on the less than stellar job done by the unlicensed contractor. This scenario is common for those homeowners who were willing to take the risk of hiring unlicensed contractors, believing that they would be able to save money by doing so. Very rare are the times when a homeowner does indeed save money by doing so. Unfortunately, the risks far outweigh the possible benefits.

Fortunately, Arizona penalizes those unlicensed contractors who would be caught. Despite this, however, it still does not really benefit the homeowner. This is because it generally takes a very long time before court-mandated refunds, whether a fraction of it or in full, may be received by the homeowner. We’re talking about years, on average.

While some contractors aren’t required to obtain their licenses for certain projects that do not amount to $1,000, you still need to err on the side of caution and go for licensed contractors. Save yourself the headache and the unnecessary expenses. Many homeowners learned their lesson the hard way.

Arizona Contractor License Search & Lookup

The Registrar of Contractors of the state maintains an online database where anyone can verify the licenses of contractors. You may check the status of the license of a contractor at https://roc.az.gov/contractor-search. The state also has a Posting List that has the names of all contractors that are currently licensed in the state. This can be accessed at https://roc.az.gov/posting-list.

Biggest Cities and Towns

Are you a contractor who wishes to work somewhere in Arizona? Fortunately, the contractor licenses issued at the state-level by the Registrar of Contractors is generally recognized throughout the different cities and towns of the state. This means that if you got your license anywhere in Arizona, you can do contracting work in any other city or town as well, even in the biggest ones like Mesa, Phoenix, Gilbert, and Scottsdale. However, you still need to check with the town or city government for any other requirements that you need to submit before doing any contractor work in their area, aside from your Arizona-issued contractor license, of course.

Contractor license exceptions generally apply to the different cities and towns, in accordance to the Arizona Revised Statutes, specifically those covered by 32-1121A. If the exception applies to you, you need to fill out the application form for exemption and submit it to the city or town government.

City of Phoenix

If you plan to do any contracting work in the city of Phoenix, you should know that their rule is that any contractor that will work on a single-family dwelling contract, as well as on a commercial contract, that amounts to more than $750 is required to be licensed. This is instead of the $1000 contract cost minimum threshold set by the state. You can learn more about this ruling at https://www.phoenix.gov/pddsite/Documents/TRT/dsd_trt_pdf_00371.pdf#search=contractor%20license.

City of Mesa

While subcontractors are required by the state to obtain their contractor licenses as well, it is a different story when it comes to taxation in the city of Mesa. This is because only the contractors, and not subcontractors, are required to pay taxes in the city. You can check this for more information: https://www.mesaaz.gov/business/tax-audit/tax-information/transaction-privilege-tax/construction-contracting.

However, contractors are still required to register with the city before doing any contracting work. If you will be doing any contracting work here, make sure to register first through this website: https://www.mesaaz.gov/business/fire-prevention/contractor-registration. Contractor registrations in this city are handled by the city’s Fire and Medical Department.

City of Scottsdale

Contractors, before they can work in any of the city of Scottsdale’s Housing Rehabilitation Programs, must first submit their application to the city. If you plan to work on any of their three programs for it, you can download the application form at https://www.scottsdaleaz.gov/Assets/ScottsdaleAZ/Social+Services/housing/Contractor+Application.pdf. Even if you get approval, you need to apply for this program each year.

Town of Gilbert

Before you can work as a contractor in the town of Gilbert, you also need to register with their Fire Prevention Division, in accordance to their laws. You can register online at https://www.gilbertaz.gov/departments/fire-and-rescue/fire-prevention/contractor-registration.

Contractor License Reciprocity

Fortunately, Arizona has license reciprocity agreements with some other states, specifically Utah, Nevada, and California. This means that if you are issued a contractor license in Arizona, you can get the same type of license or its equivalent in the reciprocal state without having the need to fulfill every single requirement for applicants who want to obtain a contractor license there, including passing the required trade exams. However, contractors issued licenses in any of those three states are still required to take the Business Management exam of Arizona.

You can find the requirements for contractors who want to be licensed using the reciprocity agreement, per state, below:

  • Utah – your experience in the trade in either Utah or Arizona must be equal to the amount required by the other state. You can refer to https://dopl.utah.gov/licensing/contractor_reciprocate_charts.html for the complete list of contractor license classifications conversion between Utah and Arizona. You also need to fulfill Utah’s bond requirement.
  • Nevada – you may be exempted from taking the trade exams if you have a valid license issued in Arizona, but plumbing and electrical contractors still need to take their trade exams in Nevada to get their license in that state. Nevada also requires that you present proof that you were issued your Arizona contractor license and this has been valid for at least the last five years out of seven.
  • California – despite having your license bond in Arizona, you still need to show proof that you have a license bond in California worth $15,000. You may be granted an examination waiver for both states but you still need to take California’s Business Law exam before you may be granted a license. You can also check the list of reciprocal license classifications between Arizona and California at http://www.cslb.ca.gov/Contractors/Applicants/Reciprocity/Reciprocal_Classifications_List.aspx.
