Licensed Electrical Services for Arizona Homes
From a flickering light to a full service upgrade, electrical problems in Tempe rarely stay small. Delta Home Services is licensed by the Arizona Registrar of Contractors under ROC 291852, classification R‑11 Electrical, and our electricians work to the code Tempe has adopted. We handle panel and service upgrades, circuit and outlet work, aluminum branch‑wiring repairs, EV charger installation and emergency service from 6 AM to 7 PM — 1,800+ jobs in Tempe since 2003. We’ll tell you whether a permit applies.
Your electric bill shows which utility serves your home. Age matters in Valley houses. The U.S. Consumer Product Safety Commission reports that homes built before 1972 and wired with aluminum branch circuits are 55 times more likely to have a connection at an outlet reach what CPSC calls “Fire Hazard Conditions” than homes wired with copper. Newer houses have the opposite problem: a service sized long before anyone ran a Level 2 charger, a heat pump and an induction range off the same panel.
Electrical Work in Tempe: Older Homes, a Code Change and Historic Districts
Tempe has the oldest housing of the five cities on our electrical pages. In the Census Bureau’s 2020–2024 American Community Survey, 35.8% of Tempe homes were built in the 1960s and 1970s, 41.2% before 1980, and the median home dates to 1984; another 21.9% were built in the 1980s. The U.S. Consumer Product Safety Commission notes that cables installed between 1965 and the mid-1970s in new homes, additions and rewired circuits may contain aluminum wiring, and its survey found that homes built before 1972 and wired with aluminum were 55 times more likely than copper-wired homes to have outlet connections reach fire hazard conditions.
The code is changing this year. Tempe adopted the 2023 National Electrical Code and the 2024 International Codes effective July 1, 2026. Through December 31, 2026, permit applications may be submitted under either the older or the newer adopted codes, and from January 1, 2027 every application must comply with the 2023 NEC and local amendments. If you are planning a panel change or rewire, the timing of the application can affect which code applies. We’ll tell you whether a permit applies.
Historic districts add a step for work on the outside of the house. Tempe’s Historic Preservation Office reviews exterior changes to properties on the Tempe Historic Property Register, such as homes in the Roosevelt Addition, University Park and Date Palm Manor. Its list of permit activities that don’t need that review includes interior electrical work not exposed on the building exterior, replacement or repair of an existing exterior service drop, service entrance or meter, and relocating one to the rear or side of the main building. Tempe also notes that homeowners associations can enforce design standards beyond city ordinances.

Frequently Asked Questions
Electrical Service in Tempe, AZ
Is Delta licensed for electrical work?
Yes. Delta Electric Services, LLC holds an active Arizona ROC license, number 291852, in classification R‑11 Electrical — the residential classification the Registrar of Contractors defines as installing and repairing residential electrical systems. You can look the license up yourself on the ROC website before you let anyone in the door.
Do you offer emergency electrical service in Tempe?
Yes. Our phones are answered 24/7. For true emergencies — a burning smell at a panel or an outlet, sparking or scorched receptacles, a cover plate that’s hot to the touch, or a total loss of power that isn’t your utility’s outage — we dispatch a technician between 6 AM and 7 PM. Call (623) 240-9892. If something smells like it’s burning and you can reach the breaker safely, shut that circuit off before you call.
Which electrical code applies to my Tempe project?
It depends on when the permit application goes in. Tempe adopted the 2023 National Electrical Code effective July 1, 2026. Through December 31, 2026, applications may be submitted under either the older or the newer adopted codes; from January 1, 2027, all must comply with the 2023 NEC and local amendments. We’ll tell you whether a permit applies.
My Tempe home is on the historic register. Does electrical work need design review?
Often not. Tempe’s Historic Preservation Office lists interior electrical work not exposed on the building exterior, and replacement or repair of an existing exterior service drop, service entrance or meter, among permit activities that don’t need its review. Moving that equipment to the rear or side of the house is also on the list. Other exterior changes may.
Does my HOA have a say in exterior electrical work in Tempe?
It can. The City of Tempe notes that homeowners associations have the legal authority to enforce maintenance and design standards in addition to those set by city ordinances. Before adding exterior lighting, a new meter location or other visible equipment, check your association’s rules; if approval is needed, we can give you the details of the planned work.
