Commercial Electrical
Rough-in through trim, feeders, branch circuits, devices and gear — self-performed by our own crews.
Arizona Electrical Solutions — Phoenix
Commercial Electrical & Design-Build in Phoenix
Four Arizona ROC licences under one contract: building, engineering, electrical and mechanical. We self-perform the trench, the pad, the gear and the wire across the Valley — so the coordination happens inside our office instead of in your weekly meeting.
Capabilities
What we do
Design-Build
One contract for design and construction. On electrical work it is usually the difference between hitting a date and explaining one.
Switchgear & Distribution
Service entrances, switchboards and distribution gear — including the APS or SRP coordination that decides your schedule.
Underground & Heavy Equipment
Trenching, duct banks, conduit, pads and restoration with our own iron and our own operators.
Electrical Engineering
Load studies, one-lines, photometrics and permit sets, with a licensed Arizona PE coordinated where a seal is required.
Power Studies
Short-circuit, coordination and arc-flash studies with NFPA 70E labelling.
That is the short list. Every capability is here — sixteen scopes, all self-performed.
Why one contractor for all of it
On a typical commercial job the electrical work is split between four or five companies. One trenches. One pours the pad. One sets the gear. One pulls wire. One does the site lighting. Each has its own crew availability, its own schedule and its own reason the delay belongs to somebody else.
We hold all of it under one contract. The KB-1 building licence lets us carry the prime, the KA engineering licence covers the heavy civil and the work in the public right-of-way, CR-11 is the electrical trade, and CR-39 puts the mechanical on the same paper. The handoffs that normally cost you two weeks happen between our own foremen.

Two things about the Valley that cost people money
Your city does not tell you your utility
The Valley is an APS and SRP duopoly, and municipal boundaries are not utility boundaries. SRP's own service list says "all or in part" — Phoenix, Scottsdale, Glendale, Peoria and Avondale all appear on it while APS serves parts of each. The line runs through neighborhoods and, in places, individual streets. A ZIP code will not tell you.
It matters because the two utilities are genuinely different animals. APS runs on an ACC tariff with a codified feasibility test and a five-year refund window; SRP is self-governed and its contribution in aid of construction is generally non-refundable. Their standards manuals differ, their metering thresholds differ, and their application portals differ. And there is a real municipal utility in the middle of it: the City of Mesa serves about 5.5 square miles of downtown Mesa itself — bid that as SRP and you are wrong before you start.
The Valley is running three NEC cycles at once
Arizona has no statewide building code. Every municipality adopts and amends independently, and right now that means a contractor can be under the 2023 NEC in Phoenix in the morning and an older edition in another jurisdiction that afternoon. Phoenix went to the 2023 NEC on 1 August 2025; Mesa on 8 January 2026; Glendale on 9 January 2026; Buckeye a year earlier, on 1 January 2025. Scottsdale is on the 2020. Several jurisdictions have not been verifiable from a primary source at all, which is exactly why we call the department instead of assuming.
Then there are the local amendments, which is where estimates quietly go wrong. In Phoenix, unincorporated Maricopa County and Glendale, EMT alone is not an acceptable equipment grounding conductor — those jurisdictions amend NEC 250.118(4) to require a wire-type EGC. Phoenix and Glendale also amend 334.10 to keep NM cable out of commercial buildings. None of that is in the national code book on your truck.
We publish the position for each city we work in. See the service area.
Where we work in the Valley
We are based in downtown Phoenix and run work across metro Phoenix and the wider Maricopa County market. Each city below has its own page because each city is genuinely a different job: a different code edition, a different plan review queue, and in several cases a different utility on the other side of the meter.
City pages
- Scottsdale — still on the 2020 NEC, which changes what passes inspection.
- Mesa — 2023 NEC since 8 January 2026, and the one Valley city that runs its own municipal electric utility downtown.
- Chandler — 2023 NEC.
- Gilbert — we confirm the adopted edition with the town before design starts.
- Tempe — we confirm the adopted edition with the city before design starts.
- Glendale — 2023 NEC since 9 January 2026, and it amends 250.118(4) and 334.10.
- Peoria — we confirm the adopted edition with the city before design starts.
- Surprise — West Valley growth corridor.
- Goodyear — West Valley industrial and distribution.
- Buckeye — 2023 NEC since 1 January 2025.
- Avondale — split APS and SRP territory.
- Queen Creek — Southeast Valley.
Working outside the city limits? Unincorporated Maricopa County is still on the 2017 NEC and amends 250.118(4), so a set drawn to Phoenix rules does not simply drop onto a county parcel. The full position for every city we work in is on the service area page.

What actually moves the schedule on a Valley project
Most commercial electrical schedules in metro Phoenix are not lost in the field. They are lost in two places before a crew ever mobilises: the utility application and plan review. Both are predictable, and both are why we start them in week one rather than after the drawings are finished.
Plan review takes longer than people budget for
Phoenix commercial plan review and inspections run through SHAPE PHX, which took on commercial work on 27 April 2026. The city publishes its actual turnaround rather than a promise, and the July 2026 report is worth knowing before you set a date: major commercial projects averaged 30 calendar days for first review against a 45-day goal, medium projects 33 days against a 35-day goal, and minor projects 33 days against a 25-day goal.
The counterintuitive part is that minor projects — under 5,000 square feet or under $350,000 — are the tier currently running past goal, and slower than major ones. Plan a small tenant improvement on the same review assumption as a large building, not a shorter one.
Budget the review itself, not just the permit: the Phoenix commercial plan review fee is 80 percent of the permit fee where valuation exceeds $50,000, expedited initial review is three times that, and a deferred submittal carries a $390 intake fee. One thing works in your favour — A.R.S. §9-835 limits a municipality to a single comprehensive written correction request, so a reviewer cannot drip-feed you corrections across three rounds.
The utility application should open the same week the design does
Neither APS nor SRP publishes a committed lead time for commercial new service. APS states only that timelines vary with complexity and current turnaround. To open the file at all, APS wants the official street address and legal description, the structure type and square footage, the estimated load, the voltage and phase you want, and site plans showing the desired meter location. The utility then engineers its system up to your meter from that information.
Every week that application sits unopened is a week added to the end of the job, not the start. See service and distribution for how we run that coordination, and engineering and design for what goes into the permit set.
Free tools, no signup
We built these for our own estimators and field crews and then left them open. Voltage drop, conduit fill, wire ampacity, box fill, transformer sizing and a panel schedule generator. No account, no email wall. Everything runs in your browser — we never see your numbers.
Two of these stop being optional in Phoenix. Ambient temperature correction and conduit-fill adjustment are arithmetic you can skip in a mild climate. Here, a conductor sized straight off Table 310.16 and run in conduit on a rooftop in July is undersized. The ampacity calculator applies both.
How to get a number from us
- Send what you have. A full plan set with specs and addenda, or a photograph and a paragraph. Both work; they just get different answers.
- We read it the same day. If it is a hard bid we will confirm the drawing set, the addenda and the bid date before we price anything.
- You get a scoped proposal. Inclusions and exclusions written out, and a price rather than a range. If something in the documents does not work, we will tell you that too.

Frequently asked questions
Where is your Phoenix office?
Downtown Phoenix, and we work throughout Maricopa County from it. The company is Arizona Electrical Solutions, LLC, and its four Arizona ROC licences are issued by the state and valid in all fifteen Arizona counties, Maricopa included. The numbers are on the credentials page and you can check them against the Registrar's own record.
What size commercial projects do you take?
Tenant improvements through ground-up construction and site infrastructure. We are not set up for single-outlet residential service calls, and we will say so rather than send out someone who is the wrong fit for the job.
Do you work as a subcontractor to a general contractor?
Often. Send the plan set, the relevant specification sections and the bid date, and you will get a scoped proposal back with our inclusions and exclusions written out. We also hold prime contracts directly, under our KB-1 building licence.
Do you offer 24/7 emergency service?
No. We do scheduled, permitted commercial work during posted business hours, Monday through Thursday 6:00 AM to 3:00 PM and Friday 6:00 AM to 2:00 PM. Some projects require night or weekend work and we schedule and price that in advance, but we do not run an emergency call desk and it would be dishonest to advertise one.
Which electric utility will serve my project?
It depends on the exact address, not the city. APS and SRP both serve parts of most Valley cities, and downtown Mesa has its own municipal utility. Send us the address and we will confirm the serving utility before anything else happens, because the service application is usually the longest lead item on the job.
Which NEC edition applies to my project?
Whichever edition your jurisdiction has adopted, and they do not agree with each other. Arizona has no statewide building code. Phoenix is on the 2023 NEC as of 1 August 2025, Scottsdale is on the 2020, and several Valley cities are on older editions or in transition. We confirm the edition and the local amendments with the building department for every project rather than assuming.
Can you handle permitting?
Yes. Commercial permitting in the City of Phoenix runs through the SHAPE PHX portal, which took on commercial plan review and inspections in April 2026, with the counter at 200 W Washington Street. Every Valley city has its own portal and its own process, and we manage that as part of the work.
Do you have a professional engineer on staff?
No, and we will not claim one. Where a project needs stamped drawings we coordinate a licensed Arizona PE and are explicit about which parts of the design are ours and which are theirs. Our in-house team does load studies, one-lines, panel schedules and photometrics.
How much does a commercial electrical project cost in Phoenix?
We do not publish ranges, because a range is not useful to anyone pricing real work — the same square footage can differ by a factor of three depending on the service size, whether the gear is available, how much trenching is involved and which utility is on the other side of the meter. Send the plans, or a photograph and a paragraph, and you get a scoped proposal with inclusions and exclusions written out and a price rather than a range.
Do you pull permits in the other Valley cities, or only in Phoenix?
All of them. An Arizona contractor's licence is issued by the state and is valid in all fifteen counties, so the licence is never the constraint. What changes city by city is the adopted code edition, the local amendments and the review queue, which is why we confirm the adopted edition with the jurisdiction before design starts rather than assuming the edition next door applies.
What is the practical difference between APS and SRP on my project?
They are genuinely different animals. APS runs on an Arizona Corporation Commission tariff with a codified feasibility test and a five-year refund window on contribution in aid of construction. SRP is self-governed and its contribution is generally non-refundable. Their standards manuals differ, their metering thresholds differ and their application portals differ. And your city does not tell you which one serves you — the boundary runs through neighbourhoods and, in places, individual streets.
Can you design a project without building it?
Yes. Design is a deliverable we sell on its own, to anyone who needs a set drawn, and we do not require that we build it. We produce the load study, the one-line, the panel schedules, the photometrics and the permit set, and a registered Arizona professional engineer reviews it, revises what needs revising and seals it. The engineering and design page covers what is in a set.
Do you take on work outside Maricopa County?
Our licences are state-issued and valid in every Arizona county, so yes in principle. In practice our crews, our yard and our utility relationships are built around metro Phoenix and Maricopa County, and that is where we do our best work. Ask, and we will tell you honestly whether a job outside the Valley is one we should be bidding.
