Tenant improvement and renovation electrical in the Phoenix Valley

A tenant improvement, or TI, turns leased space into space that fits the business moving in. A cold shell may have little more than a service stubbed into the suite. A white box, sometimes called a vanilla shell, usually has a panel, basic lighting and finished walls ready for the tenant layout. A second-generation space has plenty of wiring, most of it in the wrong places for the new tenant.

Renovations and remodels follow the same steps in space that is already in use, often by the owner. A dental practice adding operatories, a restaurant reworking its kitchen line and an office refreshing its lighting all start with finding out what is live, what can be reused and what has to go. Good circuits get reused and labeled. Abandoned wiring gets removed or made safe so it does not confuse the next person who opens the ceiling.

The lease decides who pays for what. A landlord work letter might promise a panel of a certain size, a set number of light fixtures, or a white box condition before the tenant takes over, with a TI allowance toward the rest. We read the work letter alongside the plans and can split the quote into landlord work and tenant work, so the allowance draw is easy to document and nobody pays twice for the same panel.

Demising a larger space into smaller suites raises its own questions. Each new suite usually needs its own panel and, when tenants pay for their own power, its own meter, which brings the utility into the job. Older buildings often have circuits that cross from one suite into another. We trace them, move them to the right panel and update every panel schedule, so each tenant controls only their own space.

When an architect or engineer has drawn the electrical plans, we bid and build to them. We read the drawings before pricing, note conflicts and gaps, and send RFIs through the general contractor or design team. When the specs call for submittals, we send fixture cut sheets, panel and gear submittals and lighting control details for approval before anything is ordered.

Smaller spaces often do not have full drawings. For those, we work design-build. We walk the space with you, talk through where people will sit, what equipment is coming and how the lighting should work, then write a scope and price around it. Depending on the city and the scope, the permit may need drawings sealed by an Arizona-registered engineer. When it does, we work with your engineer or bring one in, and we raise it early so it is in the schedule and the budget.

On most build-outs and renovations we are one trade among several. Framing, mechanical, plumbing, fire sprinklers, low-voltage and ceilings all need the same ceiling space and the same weeks on the schedule. We work to the GC's schedule, attend coordination meetings when asked, and tell the superintendent early if something will hold us up.

Rough-in is finished and inspected before walls close. Before the ceiling grid is filled in, we confirm that boxes, fixtures and sensors are where the plans show them. Change orders are written and priced before the extra work happens, so the owner, the tenant and the GC all know what was added and why. Pay applications and lien waivers follow the GC's process.

A remodel in a space that stays open has to be planned in phases. A medical or dental office may keep seeing patients in half the suite while the other half is rebuilt. A restaurant may need its kitchen back for the next service. A store may stay open while the back of house is redone. We plan each phase with the GC and the owner so power, lighting and exit routes keep working in the occupied areas.

Shutdowns are scheduled for nights, early mornings or closed days, and you know ahead of time which circuits will be off and roughly how long. When equipment has to stay running while the circuits around it change, we set up temporary power. Emergency lights and exit signs in the occupied part of the space stay working through every phase, and at the end of each shift, work areas are closed off and walkways are clear.

Tenant improvements and renovations with electrical work almost always need a permit, and many go through plan review before work can start. How long review takes is up to the city, so we do not promise dates we do not control. We make sure our part of the submittal is complete and answer reviewer comments quickly. Once the permit is issued, we call for each inspection, such as rough-in and final, as the job reaches that stage.

Closeout is where many build-outs get rushed. We hand over typed panel schedules that match what is in the walls, as-built markups of anything that moved from the plans, lighting control settings, manuals for equipment we supplied, and the permit and inspection record. The energy code your city has adopted often requires lighting controls such as occupancy sensors and daylight zones, and we test them before turnover so they work the way the space is used.

Early. The best time is before the lease is signed or while the plans are being drawn. A look at the existing service can tell you whether the space can carry what you are bringing in, and that answer can change the budget, the work letter negotiation, or even which suite makes sense.

If the plans are done, bring us in at bid time so the electrical price reflects the full scope. For a remodel in occupied space, call before the phasing plan is set, because the shutdown schedule shapes how the phases work. Calling an electrician after framing starts usually means paying more to work around walls that are already up.
