Scottsdale
2020 NEC, 2021 I-Codes, SPUR permitting, and an SRP/APS split no ZIP code will tell you about.
Phoenix metro & Maricopa County
Where We Work
We work throughout Maricopa County from our Phoenix office. Each city below has its own page, because in Arizona each city has its own code and frequently its own answer to who supplies the power.
Why there is a page per city
Most contractor "service area" pages are a list of place names with the same paragraph pasted under each. Ours are not, because in Arizona the differences between these cities are real and they change what a job costs.
- There is no statewide building code. Every municipality adopts and amends the NEC independently. As of now the Valley is running at least three different NEC cycles simultaneously.
- Local amendments change the installation. In Phoenix, unincorporated Maricopa County and Glendale, EMT alone is not an acceptable equipment grounding conductor — a wire-type EGC is required. Phoenix and Glendale keep NM cable out of commercial buildings. Glendale has its own rules for PVC protection and for how luminaires are tied off in a suspended ceiling.
- The serving utility is not the city. APS and SRP both serve parts of most Valley cities and the boundary runs through neighborhoods. Downtown Mesa has its own municipal utility entirely.
- Each city has its own portal, fees and review times. Phoenix uses SHAPE PHX; everyone else uses something different.
Finding out who serves your site
This is the first question on any commercial project, and guessing it is expensive. Four ways to get a real answer:
- Read an existing bill at the site. Fastest and most reliable if the building is occupied.
- Download the APS Phoenix Metro service territory map. APS publishes a dedicated metro-area PDF showing its territory.
- Request an SRP facility map. SRP will provide an atlas sheet for a specific location.
- Call. APS metro Phoenix and SRP both take contractor enquiries for exactly this.
Beyond APS and SRP, Maricopa County contains the City of Mesa's municipal utility, the Town of Wickenburg, Electrical Districts No. 7 and No. 8, several irrigation and power districts on the west side, and GRICUA on the Gila River Indian Community. If your site is in the far West Valley or near the reservation, confirm before you assume.
Outside Maricopa County
Our licences are statewide and the company also works in Southern Arizona. If your project is outside the Valley, tell us where it is and we will tell you honestly whether we are the right contractor for it.
Cities we work in
Mesa
The city runs its own electric utility over roughly 5.5 square miles downtown and SRP serves the rest, which changes the application, the standards and the schedule.
Chandler
2023 NEC by Ordinance 5108, split SRP and APS territory, and a semiconductor supply chain that buys gear on long lead times.
Gilbert
Commercial and industrial electrical in Gilbert, where the adopted NEC edition and the serving utility both have to be confirmed before design.
Tempe
Dense infill, ASU, and a live code transition window that runs through the end of 2026.
Glendale
On the 2023 NEC since January 2026, with local amendments that change grounding, wiring method, service entrance and fixture support.
Peoria
Amkor's $12 billion packaging campus, Loop 303 industrial, and the SRP/APS boundary question that has to be settled per address.
Surprise
2023 NEC since 1 January 2026, APS across most of the city, and unincorporated county land a mile away still on the 2017 NEC.
Goodyear
On the 2023 NEC since 23 June 2026, permits through Accela, and a utility boundary that does not follow the city line.
Buckeye
Greenfield industrial and logistics work on the 2023 NEC since 1 January 2025, a cycle ahead of the county land next door.
Avondale
2023 NEC since January 2026, SRP and APS both in play, and the Southwest Valley industrial belt on three sides.
Queen Creek
One NEC cycle behind Phoenix, mostly SRP, permits through Accela — what that means for a commercial bid.
Frequently asked questions
Do you charge extra to work in the outer Valley?
Travel to the far West Valley or the Southeast Valley is priced into the job like any other cost, and we tell you when distance is affecting a number. We do not run a hidden trip-charge schedule.
Can you work in unincorporated Maricopa County?
Yes. Note that unincorporated county has its own code position and its own permitting through Maricopa County rather than a city, and the county's energy code provisions are voluntary rather than mandatory — which is a meaningful difference from the cities around it.
Do you work on tribal land?
Projects on the Gila River Indian Community and other tribal lands have their own permitting authority and often their own utility — GRICUA, in that case. It is a different process from a city permit, not a harder one, but it has to be planned for. Talk to us early.
Which city is the hardest to permit in?
Not the one people expect. Phoenix publishes its turnaround times, and as of July 2026 major commercial projects were averaging 30 days against a 45-day goal while minor projects averaged 33 days against a 25-day goal — small jobs were running slower than large ones. Every jurisdiction has its own rhythm, and that is why we ask about the schedule before we promise a date.
Do you work outside Arizona?
No. We are an Arizona contractor working Arizona projects.
