Questions to ask
1. Are you licensed with the Arizona Registrar of Contractors (ROC) for electrical work — typically R-11 or CR-11 — and can I see the license number?
Why it matters: In Arizona, electrical contractors generally need an active ROC license in a classification that covers the work. For residential electrical systems, that is commonly the R-11 Electrical classification (install and repair residential electrical systems). Contractors who do both residential and commercial work often hold a CR-11 Electrical dual license (the scopes of commercial C-11 plus residential R-11). Ask for the exact license number and check status, classification, and any complaint history on the Arizona ROC contractor search before anyone opens your panel. A residential or dual license also matters because Arizona’s Residential Contractors’ Recovery Fund generally only helps eligible homeowners who hired an appropriately licensed residential contractor. Ask separately for proof of the required contractor bond and a current liability insurance certificate. A city business license or a truck wrap is not the same thing as a verified ROC license.
2. Who will actually open the panel on my job — and how does Arizona licensing work for the people on-site?
Why it matters: Arizona licenses the contracting business through the ROC; it does not issue a statewide journeyman or master electrician card the way some other states do. The license belongs to the business, and a qualifying party must meet the experience and exam requirements for the classification. Ask who will be on-site, whether they are employees or subcontractors, who supervises apprentices, and how the licensed contractor remains accountable for the finished work. Ask for recent similar residential jobs and whether the same crew typically handles permit and inspection follow-through. Do not assume California-style individual electrician certification applies here — verify Arizona credentials on the ROC search and ask the contractor to explain their crew structure in plain language.
3. Do you pull the electrical permit with the City of Phoenix Planning and Development Department (or my local building department), and who schedules the inspections?
Why it matters: Whether you need a permit depends on the job. Inside City of Phoenix limits, the City lists electrical updates, rewiring, and additions among residential projects that generally require a permit and inspection through the Planning and Development Department (PDD). Electrical work that needs a permit requires a licensed contractor regardless of job size. Phoenix also publishes work that is exempt from an electrical permit — for example cord-and-plug appliances into existing receptacles; like-for-like repair or replacement of certain motors, transformers, or fixed appliances of the same type and rating in the same location (with size limits); temporary cord-and-plug decorative lighting; like-for-like replacement of switches, receptacles, or similar devices rated 60 amperes or less (not a service disconnect); like-for-like replacement of circuit breakers rated 125 amperes or less other than a service disconnect, or any fuse; and certain Class 2 / Class 3 control and signal circuits that are not life-safety. Replacing a service disconnect, adding or modifying premises wiring, installing a new luminaire (fixture), or changing the wiring outside a listed utilization equipment enclosure generally needs a permit. Ask the contractor to say in writing whether your job needs a permit and why, who pulls it, who meets the inspector, and whether fees are in the quote. Confirm your exact jurisdiction — Scottsdale, Mesa, Tempe, Chandler, Gilbert, Glendale, Peoria, and other Valley cities run their own building departments, and unincorporated areas fall under Maricopa County. A discount for skipping a required permit shifts the risk to you at resale and in any insurance claim.
4. If this job touches the service or panel, how will you coordinate with APS or SRP for disconnect, inspection clearance, and reconnect?
Why it matters: In the Phoenix metro your electric utility is typically Arizona Public Service (APS) or Salt River Project (SRP), depending on service territory. Panel upgrades, meter moves, and service-entrance changes usually need utility coordination in addition to the city or county electrical permit. APS’s construction guidance notes that before APS can connect power to a panel, you generally need a site inspection with your local municipality, and APS publishes electric service requirements and preapproved residential panel lists for common service sizes. SRP publishes electric service specifications for builders and contractors and reconnects after required approvals. Ask which utility serves your address, who requests any temporary disconnect or project initiation, how long outages usually last, what you should prepare (medical devices, refrigerators, home office), and whether the quote includes waiting for utility clearance. A bid that ignores utility coordination often stalls mid-job.
5. Which edition of the National Electrical Code (NEC) will this job be permitted under in my city?
Why it matters: Arizona adopts the NEC locally rather than with one statewide electrical code cycle. The City of Phoenix currently lists the 2023 National Electrical Code among its adopted construction codes (2024 Phoenix Building Construction Code package, effective August 1, 2025, per Ordinance G-7397; see the City’s Building Construction Codes page). Ask which code cycle your permit will use, whether AFCI/GFCI, tamper-resistant receptacles, or other device rules apply to your scope, and whether any local amendments affect the work. The City is currently deferring enforcement of 2023 NEC 210.8(F) Exception 2 — the GFCI requirement for HVAC equipment — until March 1, 2027 (stated on the same Building Construction Codes page). Other Valley cities may be on a different edition — confirm with your AHJ. “We always do it the old way” is not a plan — the permit date and local adoption control which edition applies.
6. If I want an EV charger, will you use Phoenix’s residential EVSE permitting path, and does my panel and service have capacity?
Why it matters: The City of Phoenix publishes a dedicated residential Electric Vehicle Supply Equipment (EVSE) permitting guide. For existing homes, Phoenix says EVSE installs can be reviewed and permitted over the counter when the existing electrical service entrance section does not exceed 200-amp single-phase and does not need an upgrade for the new equipment. If the service entrance must be upgraded beyond 200-amp single-phase, Phoenix requires a formal plan-review submittal. Ask for a load calculation on your existing panel, whether a panel or service upgrade is required, charger amperage and circuit design, who submits the package (including through the City’s SHAPE PHX portal when that path applies), and how APS or SRP coordination fits if the service changes. A low bid that skips load math can leave you with a useless outlet — or a mid-job upgrade.
7. Given older Valley housing stock and desert conditions, how will you assess panels, aluminum branch circuits, heat on outdoor gear, and monsoon surge risk before quoting a full fix?
Why it matters: Many Phoenix-area neighborhoods still have aging Federal Pacific or Zinsco panels, aluminum branch wiring from later decades, undersized services for modern loads (heat pumps, EV chargers, home offices), or outdoor equipment that faces extreme heat and monsoon lightning and power disruptions. A low bid that only swaps the failed device can miss the larger condition. Ask whether they will inspect accessible wiring methods, panel brand/age, grounding/bonding, and available capacity; whether they recommend repair vs. partial rewire vs. service upgrade; how they protect outdoor disconnects and equipment from heat and sun; and whether surge protection is part of the scope. Require a stop-and-call process before extra work begins.
8. Will we have a written contract, and does your residential ROC license put me in line for the Residential Contractors’ Recovery Fund if something goes badly wrong?
Why it matters: Get the company name, ROC license number, scope, payment schedule, and change-order process in writing before work starts. Arizona’s Residential Contractors’ Recovery Fund is a form of financial protection tied to appropriately licensed residential contractors for eligible owner-occupants (and certain other claimants defined in statute). It is not a substitute for a clear contract, and recovery has eligibility rules, bond-claim steps, and limits — ask the contractor to confirm they hold an active residential or dual license covering the work, and review the ROC Recovery Fund page yourself before you rely on it. Verbal “we’ll figure it out” is not a contract.
9. What does the written estimate include — circuits, breaker sizes, wire type, device brands, panel work, disposal, and labor warranty?
Why it matters: “Fix the outlets” is not a scope. A good quote lists circuits affected, breaker sizes, wire type and gauge, device brands (for example GFCI/AFCI breakers or receptacles), any panel or service work, permit and inspection fees, utility coordination, debris disposal, and cleanup. Ask how they handle surprises (hidden damage, aluminum pigtails, full boxes), and require a stop-and-call change-order process. Get the manufacturer warranty and the contractor’s labor warranty in writing separately, and confirm who registers equipment when that matters.
10. Do you carry workers’ compensation and liability insurance, and is your ROC bond active — and how do you handle safe work practices on my property?
Why it matters: Electrical work involves shock, arc-flash, and fall risks. Use the ROC contractor search to confirm the license is active and the classification covers the work, then ask separately for proof of the required contractor bond and workers’ compensation coverage (or a valid exemption), plus a current certificate of liability insurance naming your address on larger jobs. Crews should follow lockout/tagout, PPE, ladder and attic safety, and heat-safety practices appropriate for Valley summers. Ask who is covered if a helper is injured on your property, and whether subcontractors bring their own insurance. “We’re bonded” alone is not a substitute for verifying the license and getting bond, workers’ compensation, and liability certificates in hand.
11. How do you handle after-hours or no-power emergencies, and can you give me recent Phoenix–area references?
Why it matters: When a main breaker fails on a Friday night or a heat wave coincides with a panel problem, response time and pricing matter. Ask what after-hours or weekend rates apply, what the minimum call-out and diagnosis fees are, and whether a prior customer gets priority. Then ask for two or three recent local references for similar jobs — ideally in a similar part of town and housing type (ranch rewire, condo panel, EV circuit, service upgrade). References tell you about punctuality, permit follow-through, cleanup, and whether the work passed inspection the first time.
Red flags
- Cannot give you an Arizona ROC license number you can verify, or the license classification does not cover electrical work (look for R-11, CR-11, or another classification that legally covers the scope).
- Offers a lower price to skip the permit, the inspection, or APS/SRP coordination on service or panel work.
- Quotes a full panel or service upgrade after a five-minute glance with no load discussion or written options.
- Pushes a large cash deposit before materials arrive, with no written scope or change-order process.
- No written contract naming the ROC license number, scope, and payment schedule.
- “Tonight only” scare pricing (“your house will burn down”) before you can get a second quote or verify the license.
- Claims a California-style individual electrician card is required statewide in Arizona, or cannot explain who the ROC qualifying party is for the company license.
Next-step checklist
- Verify each contractor’s ROC license status and R-11 / CR-11 (or other) classification on the Arizona ROC contractor search, and ask separately for proof of bond and workers’ compensation coverage.
- Ask who will be on-site, how apprentices are supervised, and who remains accountable for permit and inspection follow-through.
- Get at least two written quotes for the same scope, with circuits, breaker sizes, wire type, device brands, and any panel/service work listed.
- Confirm your jurisdiction (City of Phoenix through PDD, or another Valley city or Maricopa County) and who pulls the permit and meets the inspector.
- If the job touches the service or meter, confirm APS or SRP disconnect / clearance / reconnect steps and timing in writing.
- For EV chargers, ask about Phoenix’s over-the-counter vs. plan-review path and a panel load calculation before you buy equipment.
- Use a written contract with the ROC number, payment schedule, and a stop-and-call change-order process; review the Recovery Fund page if you want to understand homeowner remedies.
- Keep the permit record, inspection sign-offs, warranty paperwork, and final invoice for resale and future service.
