What Is Commercial & Tenant Improvement Electrical, and Who Is It For?
Commercial tenant improvement electrical is the wiring, panel, and lighting scope needed to fit an existing commercial space to a new or changing tenant — power and lighting layout, dedicated circuits for tenant equipment, subpanel installation and metering, data and low-voltage rough-in, and coordination with the general contractor and building department through certificate of occupancy. It's a fundamentally different process than a residential repair, because commercial spaces carry heavier loads, stricter code requirements, and a schedule that depends on a lease commencement or opening date, not just the electrician's calendar.
This covers property owners and property managers preparing a vacant suite for a new tenant, business owners customizing a leased space before opening day, and general contractors managing a commercial build who need an electrical partner that stays on schedule. It also covers full commercial new construction — a related but distinct scope, priced and planned differently than a tenant improvement inside an existing shell.
Commercial & Tenant Improvement
Our Tenant Improvement Process
01
Site Visit & Plan Review
we walk the space and review architectural plans if available, identifying power, lighting, data, and any dedicated equipment circuits the tenant's use requires.
02
Written Scope & Price
you get a defined scope and a number before anything is scheduled, not a phone-only guess.
03
Permitting
We file with the correct jurisdiction and, when the project needs a service or subpanel upgrade, start PG&E coordination early, since utility scheduling is frequently the longest line item in a commercial timeline.
04
Rough-In
Circuits, subpanels, and boxes go in while walls are open, coordinated with your GC and other trades so nothing gets closed up before it's inspected.
05
Inspection
The local building department reviews the rough-in before drywall goes up.
06
Trim-Out & Final Sign-Of
Fixtures, devices, and panels finished out, then final inspection through certificate of occupancy so the space is ready to open.

How Much Does Commercial Tenant Improvement Cost in Rohnert Park?
Commercial and tenant-improvement work is priced per scope after a site visit and plan review, not estimated per square foot — the same approach Bright Right Electric uses across its commercial work, because a basic office layout and a restaurant kitchen with three-phase equipment can sit on completely different ends of the cost range for the same square footage. What actually moves the number is how much of the existing panel or subpanel capacity can be reused, how many dedicated equipment circuits the tenant's use requires, and how much PG&E coordination the project needs.
What actually moves the number: the tenant's use (office, retail, restaurant, medical, light industrial), how many dedicated equipment circuits the space needs, whether the existing service or subpanel has spare capacity, and how much PG&E coordination the project requires. We give a defined, itemized quote after an actual site visit — never a phone-only guess.
Commercial & Tenant Improvement
Tenant Improvement vs. Full Commercial New Construction
| Tenant Improvement | New Construction / Full Build-Out | |
|---|---|---|
| What it means | Electrical changes inside a commercial space that already has power, to fit a new or updated tenant. | Full electrical scope for a new commercial building or shell, built from the meter up. |
| Typical permitting | Generally fewer hurdles since core service and infrastructure already exist. | Full plan review, service and distribution coordination with PG&E, and inspection through occupancy. |
| Typical timeline | Tied to the space size, scope, and whether the existing panel or service has spare capacity. | Tied to the broader construction schedule for the building. |
| Biggest risk | Conditions found once walls are opened — an undersized panel, an outdated subpanel, wiring that does not match the plans. | Utility coordination timing and full design coordination across trades. |
If you're deciding between leasing an existing space or building new, the electrical scope is one of the clearest ways to compare the two paths. Most tenant improvements move faster and cost less than new construction because the core service already exists — the work is fitting the space to the tenant, not building the system from the meter up.
Commercial & Tenant Improvement
What's Included in Our Commercial & Tenant Improvement Work
Commercial Panel, Service & Distribution
Service upgrades and changes, switchgear and panelboard replacement, three-phase service, 208-volt and 480-volt distribution, and capacity additions for new equipment or EV charging — the foundation most tenant improvements build on top of.
Commercial Subpanel Installation
A secondary distribution panel fed from the main service, sized and placed to bring power to a tenant suite, kitchen, or equipment area without running every circuit back to the main gear — with correct phase balancing on three-phase loads and proper feeder sizing for the distance involved.
Commercial LED Lighting Retrofits & Title 24
Replacing fluorescent, metal halide, or high-pressure sodium lighting with LED, commonly cutting lighting energy use by 50 to 75 percent. We scope the Title 24, Part 6 lighting controls — occupancy sensing, dimming, daylighting — alongside the fixtures so the project passes inspection the first time.
Commercial EV Charging
Level 2 charging for employee, customer, tenant, or fleet parking. Service capacity analysis, trenching and conduit routing, load management across multiple ports, and ADA-compliant stall placement, plus spare conduit for future ports while the trench is already open.
Commercial Backup Power
Standby generator installation and automatic transfer switch wiring, critical-loads distribution design, and commercial battery storage — sized to what the operation actually needs to keep running, since a public safety power shutoff is a revenue event for most businesses, not an inconvenience.
Commercial Appliance & Equipment Circuits
Dedicated circuits and disconnects for commercial kitchen equipment, walk-in coolers and freezers, HVAC and rooftop units, and production or shop machinery — sized correctly the first time, because voltage, phase, and connection type determine whether a piece of equipment needs a simple circuit or a service upgrade.
Commercial Data & Low-Voltage
Structured cabling, Cat6 and fiber runs, server room build-out, and security camera and access control wiring, coordinated with the electrical rough-in so it's in place before walls close.
Tenant Improvement Electrical
Complete electrical for tenant build-outs and change-of-use projects: power and lighting layout, dedicated circuits for tenant equipment, subpanel installation and metering, data and low-voltage rough-in, and coordination with your GC and the building department through certificate of occupancy.

What Rohnert Park Customers Are Saying
"This is the most professional company I have ever worked with. I am a difficult person and hard to please (I have really high standards (as a retired science teacher) and I am skeptical of workmen and I'm a perfectionist!). Bright Right is currently working on the 3rd job I have hired them for – everything has gone smoothly, no stress at all!!! They are so friendly and so courteous. Rick and Dustin are an effective team with their two unique personalities – both very upbeat, serious, and kind. They explain everything in detail and answer all my questions (I am hyper-concerned about my property), and they are basically experienced, conscientious electricians you can trust."
— Nora Parker · Google Review
"I recently hired Dustin for some electrical work at my home, and I couldn't be happier with the results. He installed a high-quality bathroom fan, finished installing several outlets around the house, and completed a new electrical panel installation. From start to finish, Dustin was professional, knowledgeable, and clearly takes pride in doing the job right. The new panel installation was the bigger job, and Dustin handled it with real expertise. Everything was organized, labeled, and done to a very high standard, which gave me a lot of confidence in the safety and quality of the work."

"Bright Right did the electrical for our kitchen remodel and we couldn't be happier, we have since then added an EV with them and they were as good as the first time. Highly recommend!"
— Joey Evans · Google Review
"Shout out to Dustin Fildes, the electrician they sent to do the work at my house. You can tell he takes pride in his work. He's a very professional and very friendly. Individual would absolutely recommend Bright Right Electric and specifically Dustin to all my family and friends. Thank you Bright Right"

Questions
Frequently Asked Questions
How much does commercial tenant improvement electrical cost?
It's priced per scope after a site visit and plan review, not estimated per square foot, because a basic office layout and a restaurant kitchen with three-phase equipment can sit on completely different ends of the range for the same square footage.
How long does a tenant improvement take?
The timeline depends on the space, the scope, and whether a service or subpanel upgrade is needed. PG&E coordination is usually the longest line item when a utility upgrade is involved, longer than the electrical work itself.
Do you coordinate directly with our general contractor or property manager?
Yes — reading plans early and flagging electrical issues before they cost time on site is a standard part of the process, not an extra service.
Can you work after hours so we don't have to close?
Yes, where the scope allows. Tell us your constraints when you request the quote, and we'll schedule disruptive work — panel swaps, major circuit additions — for after-hours or weekends.
Can you install circuits for new commercial kitchen equipment?
Yes. Send us the equipment spec sheet before you order — voltage, phase, amperage, and connection type determine whether it's a straightforward circuit or a service upgrade, and knowing that in advance is considerably cheaper than finding out on delivery day.
Does a lighting retrofit trigger Title 24 requirements?
Frequently. California's Title 24, Part 6 brings lighting controls into the scope of many alteration and retrofit projects, including occupancy sensing, multi-level control, and daylighting. We scope the controls with the fixtures so the project passes inspection the first time.
How much can an LED retrofit save my business?
Commercial retrofits typically cut lighting energy consumption by 50 to 75 percent depending on what's being replaced, with additional savings from eliminated lamp and ballast maintenance. Buildings with long operating hours see the fastest payback.
Do you offer emergency electrical service for commercial properties?
Yes. Loss of power to a building or suite, a failed main breaker, burning smells or arcing at switchgear, and refrigeration circuits down all get priority response. Call (707) 791-5552 with the address, what isn't working, and whether neighboring units still have power.
Do you work with property managers across multiple properties?
Regularly — turnover work, common area repairs, scheduled maintenance, code corrections, and tenant-reported issues across multi-tenant and multi-family portfolios.
What's the difference between tenant improvement and new construction?
A tenant improvement modifies the electrical system inside a space that already has power; new construction builds that system from the meter up in a building that never had one. Tenant improvements are generally faster and less expensive because the core infrastructure already exists.

Electrical Panel Upgrades in Rohnert Park
Replacing an undersized or obsolete panel is the most common job we perform in Rohnert Park, and it's the one that unlocks everything else. If your home still runs original 100-amp service, a Federal Pacific Stab-Lok, or a Zinsco panel, you're working with equipment engineered for a much smaller electrical load — and, in the case of those two brands, with a documented history of breakers that fail to trip. Upgrading to 200-amp service makes EV charging, battery backup, heat pumps, and modern appliance loads possible without constantly tripping breakers. We size the new service to what your household actually needs, pull the permit, coordinate the PG&E disconnect and reconnect, and meet the inspector for final sign-off.
EV Charger Installation in Sonoma County
Bright Right installs Level 2 home charging sized to your vehicle and, just as importantly, to your panel's actual available capacity. We run the dedicated 240-volt circuit, mount and commission the charger, and handle the permit — installing Tesla Wall Connectors, universal J1772 and NACS units, and hardwired or plug-in setups across Rohnert Park, Petaluma, and Santa Rosa. The detail most homeowners don't hear until it's too late is that many Sonoma County panels can't support a Level 2 charger without a service upgrade first, so we run a load calculation before you buy equipment, not after. We can also pre-wire a second circuit if a second EV is anywhere in your future.
Standby Generators & Backup Power
Public safety power shutoffs are a fact of life in Sonoma County, and so are winter storms that take lines down in the hills. We install whole-house standby generators with automatic transfer switches that pick up the house within seconds of an outage, wire inlets and manual transfer switches for portable generators, and add whole-house surge protection so your equipment isn't damaged when the utility comes back online. We'll also tell you honestly which tier makes sense — not every home in Cotati or Penngrove needs a whole-house unit when a critical-loads panel that keeps the refrigerator, well pump, internet, and a few circuits alive costs a fraction as much.
Solar & Battery Systems
We handle new photovoltaic installation, battery storage, system additions, and remove-and-replace work when a roof needs attention or a system has failed — plus service on existing arrays that aren't producing what they should. If you inherited a solar system with the house and nobody can tell you how it's wired or whether it's still under warranty, we can assess it and give you a clear picture. Battery storage in particular has changed the math for Sonoma County homeowners: between shifting utility rate structures under NEM 3.0 and the frequency of outages, a battery paired with existing solar is often a better investment than adding more panels.
Interior & Exterior Lighting
Recessed and can lighting, full LED retrofits, under-cabinet lighting, dimmer and smart-switch installation, fixture and chandelier hanging, landscape lighting, and security and motion-sensor lighting for homes across Rohnert Park and the University District. On the commercial side we handle lighting retrofits for offices, retail spaces, and warehouses along the Commerce Boulevard corridor, including the fixture and control changes that come with California Title 24 compliance. Lighting is one of the few electrical upgrades where the difference is immediately visible, and it's frequently the cheapest way to make a dated room feel finished.
Electrical Troubleshooting & Repair
Breakers that trip for no obvious reason, circuits that go dead, lights that flicker when the dryer starts, outlets that no longer hold a plug, GFCIs that won't reset, a faint burning smell you can't locate. These are the calls where experience shows. We trace a fault to its real source instead of swapping parts and billing for guesses, which is why our repairs hold and why we get called in behind other contractors who couldn't find the problem. In older Sonoma County homes the cause is often a failing backstab connection, a corroded neutral, a rodent-damaged run in a crawlspace, or a decades-old junction box buried behind drywall.
Custom Homes & New Construction
Full electrical for ground-up residential builds, major remodels, and additions throughout Sonoma, Marin, and Napa County — load calculations and plan review, service and meter setup, rough-in, trim, and final inspection. We work with general contractors, designers, and owner-builders, and we're comfortable on high-end custom projects near Sonoma State University where the lighting design, low-voltage layout, and smart controls all have to be coordinated before a single wire goes in. Getting the details right at rough-in is what keeps a home safe and functional for the next forty years — and it's far cheaper than fixing it after the drywall is up.
Commercial Electrical & Tenant Improvement
Service upgrades, panel and subpanel work, dedicated circuits for equipment, lighting retrofits, EV charging for employee and customer parking, and full tenant-improvement electrical for offices, retail, restaurants, and light industrial space along Redwood Drive and beyond. We understand a commercial job runs on someone else's schedule, so we work around business hours when the scope requires it. From a single dedicated circuit to a complete build-out, you get one licensed contractor coordinating permits, PG&E, and inspection — with clear pricing and a clean, code-compliant result.
