Arizona contractors license requirements

Every Arizona contractors license is issued by the Registrar of Contractors (ROC). It is unlawful to bid, advertise or act as a contractor without a license in good standing in the name of the business (A.R.S. 32-1151). The same statute lets a court take a building permit or a hired crew as evidence that a contract existed.

The license belongs to the business, not to a person. A sole proprietor, partnership, LLC or corporation holds it, and a qualifying party (an owner, officer or regular employee) supplies the experience and passes the exams on its behalf. Unlike Washington’s single registration, Arizona licenses each trade separately and splits every trade three ways: residential, commercial, or dual for both.

Arizona’s small-job line is low. The ROC puts it in one sentence: if labour and materials exceed $1,000, or a permit is required at any price, a license is required. The exemption in A.R.S. 32-1121(A)(14) is narrower still:

• Casual or minor work only. The aggregate price of the job, across every contract for it, must be under $1,000, labour and materials included.
• No permit, no splitting. It is lost if the work needs a local building permit, is part of a larger operation, or was divided into smaller contracts to stay under the line.
• Ads must say so. An unlicensed handyman who advertises must include the words “not a licensed contractor”; without them the exemption is gone.
• Never for fire safety or gas. Hardwired smoke alarms, fire sprinklers and any work connecting to natural gas or propane need a licensed contractor at any price (32-1121(D)).
• Owner-builders. Owners improving property for their own occupancy are exempt; a sale or rental within one year of completion is evidence the work was done to sell.

How this line compares with other states is set out in handyman vs contractor license.

The ROC defines residential work as houses, townhouses, condominiums, cooperative units and everything on residential lots; commercial is everything else. Each trade comes in a residential (R-), commercial (C-) or dual (CR-) version, and the general licenses follow the same split:

None of the general classes lets you do the regulated trades yourself: electrical, plumbing, air conditioning, boilers, pools, spas and water wells must go to a contractor licensed for them. Two residential trade classes carry their own ceilings: R-61 carpentry, remodeling and repairs up to $50,000 a project, and R-62 minor home improvements up to $5,000, with no structural work. The A family covers engineering work: roads, bridges, utilities, excavating, paving and pools. Our general vs specialty comparison sets out the choice between a general class and a trade.

The ROC licenses electrical contracting as a trade classification, in the same three versions as every other trade, and the general classes above must subcontract it to a holder of one.

Each needs the trade exam for its class unless waived, and for the three electrical classes the ROC accepts the NASCLA electrical exam instead (§ 5). Our electrical contractor license guide covers how the trade path runs in other states, and the classifications guide explains how boards draw these lines.

The qualifying party takes the Statutes and Rules Exam and, unless it is waived, a trade exam, and must pass each with at least 70%. Results count only if the exam was taken within 2 years before the application (A.R.S. 32-1122(E)).

The ROC has merged some trade exams: B, B-3 and CR-61 now share one exam, and so do B-1, B-2, KB-1 and KB-2. The trade exam is waived if the qualifying party has served a licensee in the same or a comparable classification within the last 5 years. The SRE is not, unless that service was on an Arizona license. For study routes, see contractor exam prep compared.

Experience sits with the same person. A.R.S. 32-1122(E)(1) asks for 4 years of practical or management experience in the type of work, 2 of them within the last 10; accredited technical training may count for up to 2 years, and the registrar may reduce the requirement where a trade’s custom shows it is excessive.

The ROC’s application checklist runs in this order:

1. § 1Form the legal entity. LLCs and corporations register with the Arizona Corporation Commission, partnerships with the Secretary of State; a sole proprietor applies under the full name on their ID.
2. § 2Choose the classification (§ 3, § 4). The bond, the fee and the exams all follow from it.
3. § 3Pass the exams (§ 5), or file the trade-exam waiver with the application.
4. § 4Run a background check for every person named on the application through the ROC’s vendor. Checks expire 90 days after completion.
5. § 5Copy a government-issued photo ID for every person named.
6. § 6Get the license bond in the classification you are applying for (§ 7).
7. § 7Pay the fees and, for residential and dual licenses, the recovery fund assessment (§ 8).
8. § 8Submit through the ROC online portal, by mail, or in person in Phoenix; the ROC then reviews it and notifies you of errors or approval.

By statute the ROC must tell you what it decided within 60 days of a complete application (A.R.S. 32-1124(A)). The application also asks for the workers’ comp policy number if you have employees, or an attestation that you are exempt. To plan the sequence against a start date, use the license timeline estimator.

The bond is set by the classification and the gross volume of work you expect in Arizona, per license. Residential bonds have two steps:

A dual license adds the residential and commercial amounts together, and the bond must name the classification you are applying for. You may post a cash deposit with the state treasurer instead of a surety bond (A.R.S. 32-1152(D)). The bond can be raised at any time but lowered only at renewal, and a rise in volume needs a bond rider. What a bond of each size costs a year is in the bond premium calculator, and who writes them is in the surety companies compared.

The ROC’s fee schedule is for a two-year license and depends on the license family. Exam fees (§ 5) are on top.

Residential and dual licensees pay into the Residential Contractors’ Recovery Fund, or post a second bond of $200,000 instead (A.R.S. 32-1152(C)). The fund pays homeowners harmed by a licensed residential contractor: at most $30,000 per residence and $200,000 per license, and only after a claim on the license bond. Commercial licenses pay no assessment.

A license runs 2 years. It is suspended by operation of law on the next business day after its renewal date unless a renewal, with the fee and a valid bond on file, has been received or mailed by then (A.R.S. 32-1125(A)). Within a year of that suspension it can be renewed with a $50 late fee on top; after a year you apply for a new license. The renewal checklist asks you to confirm the entity is in good standing, the bond still covers your volume, and the workers’ comp details. The renewal tracker keeps the date in view.

How other states treat the same offense is in working unlicensed: what it costs.

The ROC’s Contractor Search is the register to trust. Before you sign with an Arizona contractor:

1. § 1Take the ROC number from the bid or ad; it must be there.
2. § 2Search it, and confirm the license is active and the business name matches the contract.
3. § 3Check the classification covers the work: a B-3 cannot build a new house, and a B-2 cannot take a commercial job over the class limit.
4. § 4Read the bond information the search page carries for the license.
5. § 5For electrical, plumbing or HVAC work, confirm the trade class (R-11, R-37, R-39 or their C and CR versions).

Our guide to checking a contractor license covers what a clean record still does not tell you, and the lookup directory lists every other board’s search.
