You signed the lease, the contractor has the keys, and the clock is ticking. Whether you’re building out a medical suite in North Scottsdale, refreshing a restaurant in Old Town, or opening a new office in Chandler, the electrical work is the one piece you cannot afford to get wrong. A missed circuit, an undersized panel, or an unpermitted rough-in can stall your certificate of occupancy, blow your opening date, and hand your landlord leverage you never wanted to give them. FHR Electric delivers Tenant Improvement Electrical Services for business owners and high-end commercial clients across Scottsdale, Phoenix, Gilbert, Mesa, Tempe, Glendale, and all of Maricopa County — licensed, permitted, inspected, and done right the first time so you can open on schedule and operate without fear.
The Real Cost of Getting the Electrical Wrong on a Tenant Improvement
We hear it every week. A business owner hired the lowest bidder, the work failed inspection, and now they’re paying a second electrician to tear out and redo what the first one buried in the walls. Or a restaurant opened with an undersized electrical service, lost power to the walk-in cooler on a Friday night, and spent the weekend explaining the situation to the health department. Or a dental office discovered mid-renovation that the previous tenant’s wiring was never permitted in the first place — a classic example of unpermitted electrical in Arizona that becomes your problem the moment you sign the lease.
These are not edge cases. They are predictable outcomes when electrical work is treated as a commodity rather than a specialty. The stakes in a commercial tenant improvement are higher than in almost any residential project: you have employees, customers, health and safety codes, ADA requirements, landlord approval processes, and city permit timelines all converging at once. You need an electrical specialist who has done this before — many times — not a generalist who is figuring it out on your dime.
“The electrical is the circulatory system of your build-out. Get it right once and everything else works. Get it wrong and nothing else matters.”

Our Tenant Improvement Electrical Services: What We Handle Start to Finish
A tenant improvement is not a single task — it is a sequence of coordinated electrical scopes that must align with your architect’s plans, your contractor’s schedule, your city’s permit process, and your landlord’s specifications. FHR Electric manages all of it under one licensed roof. Here is what that looks like in practice:
New Business Electrical Hookup & Service Entry
Before a single outlet goes in, we assess whether the existing electrical service — the panel, the meter base, the service entry — can actually support your operation. A new business electrical hookup for a restaurant or medical office often requires a service upgrade or a separate sub-panel. We handle the utility coordination, the replace meter base work if needed, and the APS or SRP approval process so you are not waiting on paperwork while your contractor idles.
Office Suite Electrical Wiring & Circuit Planning
Every office suite electrical wiring layout starts with a load calculation. How many workstations? What is your server or AV load? Do you need structured cabling and home office-grade data infrastructure? We map your circuits before we pull a single wire so that you never end up in the all-too-common situation of a panel out of space six months after you open. We also plan for growth — adding a circuit later is always more expensive than doing it right in the rough-in phase.
Food Service & Restaurant Electrical — Scottsdale & Beyond
Food service electrical in Scottsdale is its own discipline. A commercial kitchen demands dedicated circuits for commercial refrigerators, hood systems, dishwashers, and high-draw cooking equipment. A catering kitchen electrical contractor who understands load sequencing and commercial refrigerator circuits can mean the difference between a smooth health inspection and a failed one. We also wire tasting rooms and bar builds — including the lighting, the POS circuits, and the HVAC electrical tie-ins — so your atmosphere matches your concept.
Medical & Dental Office Electrical
Medical and dental offices have the highest electrical stakes of any tenant improvement. Equipment loads are heavy and specific. Code requirements — including isolated ground circuits, emergency lighting, and in some cases power backup for medical offices — are non-negotiable. A circuit overload or a power interruption mid-procedure is not just an inconvenience; it is a liability event. We design and install your electrical system to meet NFPA 99 healthcare facility requirements and coordinate with your equipment vendors so that everything lands on the right circuit at the right voltage from day one. For clients who want continuous uptime protection, we also offer commercial generator installation and maintenance as part of the same project scope.
HVAC Electrical Upgrade & Rooftop Equipment
In Scottsdale and the greater Phoenix valley, HVAC is not optional — it is life safety. A HVAC electrical upgrade in Scottsdale for a commercial space often involves running new dedicated circuits, installing rooftop HVAC outlets, and coordinating with the mechanical contractor to ensure every unit has the correct breaker size and disconnect. We have done this on everything from small retail suites in Tempe to multi-tenant professional buildings in North Phoenix.
Indoor Lighting Installation & Industrial Lighting Upgrade
Lighting in a commercial tenant improvement is both functional and brand-defining. We install indoor lighting across every category — recessed, pendant, track, and LED panel — with attention to recessed lighting placement that flatters your space rather than fighting it. For warehouse, production, or back-of-house environments, we handle full industrial lighting upgrades including high-bay LED retrofits that dramatically cut your energy costs without touching your production schedule.
Dedicated Circuits, Panel Work & Hazardous Panel Replacement
If the space has an aging or undersized panel, we address it before it becomes your emergency. Hazardous panel replacement — including panels with known recall or fire-risk histories — is something we do routinely in tenant improvement work. We also install all the dedicated circuits your operation requires: dedicated circuits for refrigerators, dishwashers, washing machines, specialty equipment, and more. Every circuit is labeled, documented, and permitted so the next tenant, the next inspector, and your insurance carrier all see clean, professional work.
EV Charging Infrastructure for Commercial Spaces
More Scottsdale employers and property owners are adding EV charging as a tenant amenity and a competitive differentiator. We install commercial EV charger infrastructure including 50-amp EV charger circuits, conduit runs, load management systems, and condo or shared-parking EV charging installs that handle multiple vehicles without overloading the building’s service. We understand off-peak EV charging in Arizona and can help you configure systems that minimize your utility costs.
Thermal Imaging & Pre-Occupancy Electrical Inspections
Before you flip the breaker for the first time in a new space, we offer thermal imaging electrical diagnostics to find hidden hot spots — loose connections, overloaded neutrals, and failing components — that visual inspection alone cannot catch. This is especially important when you are inheriting a space with an unknown electrical history. We give you a written report, not just a verbal assurance. Learn more about what to expect on our frequently asked questions page.

- Permit-ready work every time — we pull the permits, schedule the inspections, and hand you documentation at the end. No shortcuts that come back to haunt you at your next lease renewal or sale.
- Transparent, flat-scope estimates — we scope the job thoroughly before we quote it so that the number you approve is the number you pay. No surprise invoices when the drywall opens up.
- Commercial code expertise — we stay current on NEC, local Maricopa County amendments, and industry-specific requirements (healthcare, food service, retail) so your inspection passes the first time.
- Coordination with your general contractor — we work within your build schedule, show up when the rough-in window opens, and communicate directly with your GC so you are not playing telephone between trades.
- Long-term relationship, not a one-time transaction — after your space opens, we are your electrical team for ongoing commercial electrical services, maintenance calls, and future expansions.
Understanding what tenant improvement electrical work involves at a technical and regulatory level can help you ask better questions and make better decisions when vetting contractors — and we welcome every question you have.
How We Work: Our Tenant Improvement Electrical Process
We do not show up with a truck and start guessing. Every tenant improvement engagement follows the same disciplined process that keeps your project on time, on budget, and inspection-ready.
- Discovery & Scope Call — We start with a conversation about your space, your operation, your timeline, and your budget range. We ask the questions that most electricians skip — equipment lists, future load projections, landlord electrical specifications, and permit jurisdiction — so nothing surprises us later.
- Site Walk & Load Assessment — We visit the space, assess the existing electrical service, identify any electrical inspection violations or hazards inherited from the previous tenant, and map your new electrical layout against your architect’s or designer’s plans.
- Flat-Scope Estimate & Timeline — You receive a written estimate with a clear scope of work, a materials list, a permit cost line item, and a project timeline. We do not start work without your written approval.
- Permit Pull & Rough-In — We pull all required permits through the appropriate jurisdiction — Scottsdale, Phoenix, Chandler, Gilbert, or wherever your space sits within Maricopa County — and complete the rough-in during your contractor’s framing and drywall window.
- Rough-In Inspection — We schedule and pass the city’s rough-in inspection before drywall closes. No buried surprises, no code violations hidden in the walls.
- Trim-Out & Device Installation — After paint and finish work, we return for trim-out: devices, panels, fixtures, breakers, and any specialty equipment connections your operation requires.
- Final Inspection & Documentation — We schedule and pass the final electrical inspection, then hand you a complete as-built documentation package including panel schedules, permit records, and thermal imaging report if applicable.
- Walk-Through & Handoff — We walk every circuit with you or your facility manager, label everything clearly, and answer every question before we consider the job closed.

We work across the entire valley — from Old Town Scottsdale and North Scottsdale to downtown Phoenix, Chandler, Gilbert, Mesa, Tempe, Glendale, and Fountain Hills.
