Your space is changing — a new build-out, a suite renovation, a coffee shop taking shape, a dental office coming online — and the last thing you need is an electrician who treats your project like a side job. Tenant Improvement Electrical is a specialized discipline that demands more than a generalist with a tool belt. It requires a licensed team that understands commercial code, ADA-compliant circuits, dedicated equipment loads, and the kind of coordination with general contractors that keeps a project moving on schedule. At FHR Electric, we do this every day across Scottsdale, North Scottsdale, Old Town Scottsdale, Phoenix, North Phoenix, Chandler, Gilbert, Mesa, Tempe, Glendale, and Fountain Hills — and we bring the same licensed, permitted, and inspected standard to every square foot of your build-out.
Whether you are a restaurant owner wiring a hood exhaust system, a dentist setting up operatory circuit requirements for your compressor and imaging equipment, or a boutique retailer transforming a raw shell space into something polished and inviting, we are the team that makes the electrical portion of your project invisible in the best possible way — done right, done on time, and never a surprise on the final invoice.
The Real Cost of Getting Tenant Improvement Electrical Wrong
We hear it constantly: a business owner hired the low bidder, the work failed inspection, the general contractor had to stop the job, and weeks of revenue were lost before the space even opened. Sometimes it is worse — the building is occupied and a hard fault breaker trips mid-service, a restaurant loses refrigeration overnight, or a medical practice discovers mid-procedure that the circuit to their sterilization equipment was never properly isolated. These are not hypothetical disasters. They happen regularly when tenant improvement electrical work is handed to whoever submitted the lowest bid without checking credentials.
In Arizona, you have every right to ask for a contractor’s license number and verify it before any work begins. We encourage you to do exactly that. Our license is current, our work is always permitted, and every job we complete passes inspection the first time. That is not a marketing claim — it is our operating standard.
“The peace of mind of knowing the electrical is done correctly — permitted, inspected, and built to last — is worth more than whatever you think you are saving on the low bid.”

What We Handle: Tenant Improvement Electrical From Shell to Certificate of Occupancy
Tenant improvement projects vary enormously in scope and complexity. We have wired single-suite office refreshes and full ground-up commercial fit-outs. Here is a detailed look at what we bring to the table — and what you can stop worrying about the moment you bring us on.
Panel Upgrades and Service Lateral Work
Most tenant improvement projects discover quickly that the existing electrical service cannot handle modern loads. A 100-amp panel that served a quiet office is not equipped for a coffee shop with commercial espresso machines, a dedicated freezer bank, and point-of-sale systems on a clean circuit. We handle residential service lateral upgrades, 400 amp panel upgrades, and everything in between — coordinating directly with the utility so you never have to navigate that process alone. If the existing panel runs warm to the touch or contains a known problematic brand, we identify it immediately and present you with a clear, honest recommendation before the build-out locks you in.
Dedicated Circuits for High-Demand Equipment
Every piece of commercial equipment — from a dental compressor to a restaurant hood exhaust wiring system to a laboratory electrical installation — has specific circuit requirements. We read the equipment specs, engineer the circuits correctly, and install with the right gauge wire, breaker size, and disconnect. No guessing. No undersizing. For medical and dental clients especially, uninterruptible power and dental compressor wiring must meet a higher standard, and we deliver that standard every time. We also wire CO2 systems for restaurants and handle the coffee shop electrical requirements that most residential electricians have never encountered.
Lighting Design and Installation
Lighting is not an afterthought in a tenant improvement — it is a core part of how your customers, patients, or clients experience your space. We install tray ceiling LED strip lighting, pendant systems, recessed layouts, and large chandelier wiring for high-ceiling lobbies and dining rooms. We can also convert to LED lighting throughout an entire suite, reducing your operating costs immediately. For clients who want integrated control, we handle indoor lighting installation alongside whole home lighting control system wiring and smart switch installation — so your space looks exactly the way you envisioned it, and you control it from a panel or your phone.
Low-Voltage, Data, and Automation Wiring
Modern commercial spaces need more than power — they need infrastructure. We wire home network electrician-grade structured cabling, Crestron home automation wiring for boardrooms and high-end retail environments, and integrated AV rough-in for client-facing spaces. If your build-out includes a security system, access control, or driveway gate motor electrical hookup at a private entrance, we handle the full circuit and low-voltage side so your GC has one less coordination headache.
EV Charging Infrastructure
If your tenant improvement includes a parking area or garage, EV charging is no longer optional for competitive commercial real estate. We design and install multi EV charger setups, 60 amp circuit installation for Level 2 stations, and full charging hubs with load management. We also advise on whether your existing service can support EV infrastructure or whether a service upgrade needs to be part of the build-out budget. Learn more about our EV charger installation services and how we integrate them cleanly into new and renovated commercial spaces.
Backup Power and Generator Integration
For any business where a power outage means real financial loss — a restaurant that loses a freezer full of inventory, a medical or dental practice that cannot operate without power, a data-sensitive professional office — backup power is not a luxury. It is risk management. We wire generator transfer switches, integrate standby generator systems, and can coordinate full commercial backup solutions. Explore our commercial generator installation and maintenance services for a complete picture of how we protect business continuity.
Why Business Owners in Maricopa County Choose FHR Electric
There is no shortage of electricians in the Phoenix metro. What is harder to find is a team that combines licensed expertise, clean communication, and a genuine understanding of what is at stake for your project. Here is what makes us different — and why quality-first clients keep calling us back.
- Licensed, Bonded, and Insured — Always: We are fully licensed in the state of Arizona. You can learn more about what tenant improvement electrical work entails and what standards licensed contractors must meet. We meet and exceed all of them.
- Permitted Work, Every Time: We pull permits on every project that requires them. If an electrician tells you permits are optional or that you do not need one for your project scope — walk away. Unpermitted work creates liability, failed inspections, and problems at resale or lease renewal.
- Transparent, Detailed Bids: We give you a written scope of work before a single wire is run. No surprise line items. No scope creep billed without your approval. We believe the best electrical bid comparison tips start with comparing apples to apples — and our bids are itemized so you can do exactly that.
- Coordination with Your GC and Design Team: Tenant improvement projects are team efforts. We work fluidly with general contractors, architects, and interior designers to hit rough-in milestones, accommodate last-minute layout changes, and never be the trade that holds up the schedule.
- Panel Thermal Imaging Available: For occupied buildings and during pre-build assessments, we offer panel thermal imaging to identify hot spots, overloaded circuits, and failing components before they become emergencies — especially critical in the Scottsdale summer heat.
- Monsoon-Season and Arizona-Climate Expertise: Monsoon electrical safety is a real concern in Maricopa County. Outdoor circuits, service entrances, and disconnect equipment must be specified for our climate. We know the difference and specify accordingly.
Our Process: How a Tenant Improvement Electrical Project Works With Us
We believe you deserve to know exactly what happens from the first call to the final inspection sign-off. Here is how we work:
- Discovery Call and Site Walk: We start with a conversation — your timeline, your equipment list, your GC’s schedule, and your budget range. Then we walk the space. We look at existing service, panel capacity, ceiling heights, and any constraints that will affect the bid.
- Written Proposal: Within a few business days, you receive a detailed written proposal broken down by scope. No mystery lump sums. You will know what you are paying for and why.
- Permit Coordination: We handle permit applications and coordinate with the AHJ (authority having jurisdiction) for your municipality — whether that is the City of Scottsdale, Phoenix, Chandler, Gilbert, or another Maricopa County jurisdiction.
- Rough-In Phase: We run conduit, pull wire, and set boxes according to the approved plans — coordinating with your GC’s schedule so we hit every milestone without causing delays to other trades.
- Rough-In Inspection: We call for inspection and walk it with the inspector. Our rough-in passes the first time. If the inspector has a question, we answer it directly and professionally.
- Trim-Out and Device Installation: Once drywall and finishes are in place, we return to install devices, fixtures, panels, disconnects, and all finish electrical. This includes lighting, outlets, switches, EV chargers, and any specialty equipment.
- Final Inspection and Certificate of Occupancy Support: We call for final inspection and support your CO process. You get a fully inspected, code-compliant space ready to open.
