Moving into a new commercial space, or reworking the one you have, is a fresh start for your business. A tenant improvement turns a blank or outdated suite into a space built around how you work and how your customers experience your brand. For business owners in Queen Creek, Gilbert, Scottsdale, Mesa and Chandler, the electrical scope is one of the biggest parts of that new beginning.
Short answer: Commercial tenant improvement electrical covers the power, lighting, data and safety systems a space needs for your business. Plan it early with your architect and contractor, confirm the existing service can carry your equipment, check what the lease allows, and expect permits and inspections. Clear scope and communication keep the opening date on track.
What does tenant improvement electrical include?
- Power distribution: panels, feeders and circuits sized for your equipment
- Lighting design, fixtures and controls
- Dedicated circuits for kitchens, refrigeration, POS, servers and specialty equipment
- Data and low-voltage pathways for networks, phones, cameras and AV
- Emergency and exit lighting
- EV chargers for staff or customers, where planned
- Panel labeling, testing and final inspection
What’s exciting about a tenant improvement?
Plenty. You get to design a layout around your workflow, choose lighting that shows off products or sets the mood, bring your brand into the finishes and add technology that supports how you’ll operate. Watching a raw suite turn into a lit, finished space is one of the best parts of our job. Our post on commercial lighting design covers how lighting choices shape a space.
How do I plan the electrical for a tenant improvement?
- Share your plans and equipment list. Kitchen equipment, refrigeration, servers and specialty machines drive the electrical design.
- Review the existing service. We check whether the panels and service can carry the new load, or whether changes are needed.
- Coordinate with the architect and contractor. Lighting, power and data are laid out on the permit drawings.
- Pull permits. We pull the electrical permit where required and coordinate any SRP or APS service work.
- Rough-in and inspection. Wiring, boxes and pathways go in and are inspected before ceilings and walls close.
- Trim, testing and handoff. Fixtures, devices and controls are installed, tested and labeled before final inspection.
What should business owners watch for?
- Lease terms: what the landlord allows, what needs approval, and what improvements stay with the space
- Existing conditions: older suites can hide outdated wiring, full panels or a previous tenant’s tangle of circuits
- Service capacity: restaurants and equipment-heavy businesses may need more power than the suite has
- Permits and inspections: they take time, so build them into the schedule
- Scope changes: late changes to layouts or equipment can affect wiring and timelines
- Lead times: specialty fixtures, controls and gear can take weeks
- Future growth: spare capacity and pathways make later changes easier
What does a real tenant improvement look like?
For the Ponderosa House tenant improvement for a bar and restaurant in Old Town Scottsdale, the electrical scope covered the full space, including a Lutron lighting control system with a hub controller so the owners can dim the lights and switch scenes through the night. Read our Ponderosa House wrap-up for the story.
What panels and protection do you install?
We usually install Square D or Eaton panels and materials, organized and labeled for easy service. For sensitive equipment like POS systems, servers and AV, we recommend surge protection. If staff or customers need EV charging and capacity is tight, a power-monitoring, load-managing EV charger can help avoid a service upgrade. See our commercial tenant improvements page for more.
Tenant improvement electrical checklist
- Equipment list and plans shared with the electrician
- Existing service and panels evaluated

When should I call an electrician?
Before you sign the lease, if you can, so you know whether the space can support your equipment. During the project, keep staff away from open panels and exposed wiring. In an operating space, call us if breakers trip often, lights flicker, or you smell burning. Turn off the breaker only if it’s safe and dry to reach, and call 911 for any fire. We answer emergency calls 24/7.

Frequently asked questions
What is commercial tenant improvement electrical work?
It’s the electrical scope that customizes a commercial space for a tenant: power distribution, lighting and controls, equipment circuits, data pathways, emergency lighting and final inspection.
When should I involve an electrician in a tenant improvement?
As early as possible, ideally before you sign the lease, so you know whether the existing service can carry your equipment and how that affects the plan.
Do tenant improvements need electrical permits?
Usually, yes. Most TI electrical work needs a permit and inspections. We pull permits where required and coordinate the inspections.
Can an existing suite handle restaurant equipment?
Sometimes. Kitchens, refrigeration and bar equipment add a lot of load. We review the existing service and panels to see whether changes are needed.

Yes. We coordinate with the general contractor, architect and property manager to keep the electrical scope aligned with the plans and schedule.
