How to start temp power in Arizona: license, cost, and timeline

Last updated 2026-08-18

Do you need a license for temp power in Arizona?

Yes, you almost certainly need a license. Arizona law says anyone who contracts to perform electrical work on a project with a total cost (labor and materials) of $1,000 or more must hold a contractor's license from the Arizona Registrar of Contractors (ROC) ^[1]. Temporary power jobs, like setting up generators and distribution panels for events or construction sites, usually cross that threshold fast. Even a small generator rental plus cable and labor can easily top $1,000.

There is no separate 'temp power' license. The state covers all electrical work under the same C-11 Electrical classification, which includes temporary installations ^[2]. If you're only doing work under $1,000, you could technically operate without a license, but that's a razor-thin margin and most insurance companies won't cover unlicensed electrical work. The ROC's experience requirement is four years of verified electrical experience for the qualifying party ^[6]. So you can't just start tomorrow; you need that background.

What kind of license do you need for temp power in Arizona?

The C-11 Commercial Electrical license is the one that covers temporary power for events, commercial construction, and industrial sites. If you also plan to do residential temporary power, like for a home renovation, you'd need the R-11 Residential Electrical license, or you can hold both. The ROC defines the scope of C-11 as 'all electrical work including temporary wiring and power distribution' ^[2].

To get a C-11, you need a qualifying party who has at least four years of practical experience in electrical construction, with at least two of those years as a journeyman or supervisor, all documented ^[6]. You'll also need to pass two exams: the Arizona Business Management exam and the C-11 trade exam ^[5]. The exams are given by PSI, and the fee is $66 per exam. The business exam covers things like contracts, liens, and safety rules; the trade exam covers NEC code, load calculations, and practical installation. Once you pass both, you submit your bond and license fee. The license is issued to a business entity, with the qualifying party as the responsible individual.

How much does temp power cost in Arizona?

Startup costs for the license itself run around $1,500 to $2,000, depending on bond premiums. Here's a breakdown of the fees from the Arizona ROC ^[3]:

Fee	Amount
Application fee (new license)	$580
Business Management exam	$66
C-11 Trade exam	$66
License fee (2-year)	$440
Surety bond (annual premium)	$100, $200
General liability insurance (annual)	$500, $1,000

The bond is a $10,000 surety bond required by the ROC for all C-11 contractors ^[4]. The premium is not a fixed fee; it depends on your credit and the bond company. Most contractors pay around $150 for the first year. The bond protects consumers if the contractor fails to follow laws or contracts.

General liability insurance isn't mandated by the ROC, but it's a standard requirement for events and construction sites; without it, you won't get hired. Expect to pay $500, $1,000 a year for a basic policy with $1 million in coverage.

You'll also need to budget for business registration with the Arizona Corporation Commission if you form an LLC or corporation, which costs $50, $85. The city of Phoenix, for example, requires a special event permit for temporary power setups, which can cost $100, $500 depending on the event size ^[8]. So total first-year outlay, including equipment rental or purchase, can easily reach $5,000, $10,000.

How long does it take to get licensed for temp power in Arizona?

The Arizona ROC says it takes about 60 days to process a complete license application ^[7]. That's from the day you submit all paperwork, pay the fee, and pass the exams. In practice, gathering the experience documentation and scheduling exams can add a few weeks. The experience verification forms require signatures from past employers or supervisors, and the ROC may audit them.

If you already have a qualifying party with all documentation ready, the process can be closer to 45 days. If there are gaps or questions, it can stretch to 90 days. The ROC's processing times page shows that most electrical applications are processed within 60 days as of 2025. So plan for two to three months from start to license in hand.

What about insurance and bonds?

The ROC requires a $10,000 surety bond for all C-11 contractors ^[4]. This bond is not insurance; it's a guarantee to the state and consumers that you'll follow the law. If you don't, the bond pays out, and you owe the bond company. The premium is typically $100, $200 per year.

General liability insurance is separate and not required by the ROC, but it's demanded by almost every event promoter, general contractor, or venue. A basic policy with $1 million per occurrence and $2 million aggregate costs $500, $1,000 per year. Workers' compensation insurance is required by Arizona law if you have any employees ^[10]. If you're a sole proprietor with no employees, you don't need it, but you might want a health insurance policy. Some clients also require pollution liability if you're using diesel generators. Factor that in.

Can you start without a license in Arizona?

Technically, yes, if you keep every single job under $1,000 total. But that's nearly impossible for temp power work. A single generator rental, fuel, and a cable run will push you over that limit. And if you get caught contracting without a license, the ROC can issue a civil penalty of up to $1,000 for the first offense, and you could be barred from getting a license later. Many cities also require a contractor's license to pull a permit for temporary power, so you'd be shut out of legitimate work. The risk isn't worth it. Get the license.

How much does temp power equipment cost in Arizona?

Equipment costs vary wildly. You can rent a 20kW generator for a weekend event for about $200, $400. A used 50kW generator might cost $8,000, $15,000 to buy. Add distribution panels, cables, and connectors, another $2,000, $5,000 in good used gear. Some companies, like TempPowerPath, offer a one-time kit for $179 that includes essential cable, fuel, and a 480V kit, which can be a cheap way to start with minimal gear. But that's just the basics; you'll need more equipment as you grow. Renting is often smarter at first, until you have steady contracts.

Renewal and ongoing compliance

Your C-11 license is valid for two years. The renewal fee for a commercial license is $440, due before the expiration date. You must also keep your bond active; the ROC will verify that at renewal. If your qualifying party leaves, you have 90 days to replace them or the license becomes inactive. Continuing education is not required for Arizona electrical contractors, but you must stay current on NEC code updates. The ROC can audit your experience or financials at any time, so keep good records. Renewal is straightforward if you're in good standing ^[9].

Local permits for temp power in Arizona

Beyond the state license, many Arizona cities require a separate permit for temporary power installations. For example, the City of Phoenix requires a Special Event permit for any event that uses temporary electrical service, which includes a site plan showing the generator and cable routing ^[8]. The permit fee is based on the size of the event and can run $100, $500. Tucson and Mesa have similar requirements. Always check with the local building department before you bid a job. The city will often require an electrical permit with a licensed contractor's signature, so having your C-11 license is a prerequisite anyway.
