Commercial Whole Home Rewiring
What Is Commercial Whole Home Rewiring?
Commercial whole home rewiring replaces outdated or undersized wiring in a business, retail space, restaurant, warehouse, or multi-tenant building — common-area circuits, tenant space wiring, panels and subpanels, and three-phase power distribution — with a system built for today's equipment and code requirements. This page covers commercial and light-industrial rewiring; if you're a homeowner, our residential whole home rewiring page is the better fit. Rewiring frequently overlaps with panel work — see Service Entrance Upgrades Commercial and Subpanel Installation Commercial for what those projects involve on their own.
Commercial Whole Home Rewiring
Our Process
Commercial rewiring is a coordination job as much as an electrical one — here's how we plan around your business.
01
Walkthrough & scope assessment
We identify what's infrastructure-level work versus tenant-improvement-level work, since that distinction often determines who pays for what.
02
Written estimate
You get a price in writing, scoped to the actual work needed.
03
Permit filed
We file the permit before work begins.
04
Phased rewiring by zone
We work section by section, scheduling disruptive portions during off-hours or weekends where needed, so most of your space stays operational.
05
Coordination with your property manager or other tenants
In a multi-tenant building, we coordinate scheduling so businesses outside the current scope aren't affected.
06
Final inspection & closeout
Every circuit is tested and the permit closed out clean.

What Does Commercial Rewiring Cost?
Commercial rewiring typically runs $5 to $12 per square foot, generally 10 to 30 percent more than residential rewiring, reflecting higher outlet density and commercial-grade code requirements. The exact number depends heavily on your building's age, existing infrastructure, and whether the scope includes three-phase power, dedicated equipment circuits, or panel replacement.
Those are honest general ranges, not a locked-in Bright Right Electric quote — the fastest way to get an exact number is a walkthrough. Call (707) 791-5552 or request a quote below and we'll scope your space and tell you plainly what it'll cost.
Commercial Whole Home Rewiring
Who Pays — You or Your Landlord?
It depends on your lease and the scope of work, and it's one of the most common points of confusion in commercial electrical projects. Landlords often handle rewiring of common-area circuits and shared building infrastructure — the systems serving the whole building rather than one tenant's space. Tenants are typically responsible for their own tenant-improvement-level electrical work within their leased space. Sometimes the two overlap: if a new tenant's equipment doesn't match what the building's electrical infrastructure was originally designed for, a combined infrastructure-plus-TI project may be needed. Reviewing your specific lease language is the reliable way to confirm which applies to you — and we're glad to help you make sense of the electrical side of that conversation before anything gets billed.

Will This Shut Down Our Business?
In most cases, no. Commercial rewiring can usually be phased by zone or scheduled during off-hours and weekends, so only the specific area under work loses power while the rest of your space keeps operating. In a multi-tenant building, we coordinate with your property manager so businesses outside the current scope aren't affected either. If a brief shutdown is genuinely unavoidable for a specific step — like a panel swap — we'll tell you exactly when and how long, so you can plan around it instead of being surprised by it.
Commercial Whole Home Rewiring
What's Included
Commercial whole home rewiring covers a range of building types and scopes. Here's what falls under it.
Common-Area & Infrastructure Rewiring
Rewiring the shared circuits and systems serving a multi-tenant building, typically the landlord's scope.
Tenant Improvement Electrical
Rewiring within a specific leased space, scoped to that tenant's equipment and layout.
Three-Phase Power
Rewiring for 120/208V or 277/480V three-phase power distribution, common in commercial and light-industrial buildings.
Dedicated Equipment Circuits
Circuits sized for commercial kitchen equipment, server rooms, or specialized machinery, based on actual equipment load.
Fire Alarm & Emergency Egress Lighting Coordination
Rewiring around existing life-safety systems carefully, so fire alarm circuits and emergency egress lighting stay code-compliant throughout the project.
Panel & Subpanel Replacement
Commercial rewiring frequently uncovers an outdated panel or subpanel. See Service Entrance Upgrades Commercial and Subpanel Installation Commercial for what those projects involve.

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."

Questions
Frequently Asked Questions
How much does it cost to rewire a commercial building?
Commercial rewiring typically runs $5 to $12 per square foot, generally 10 to 30 percent more than residential rewiring due to higher outlet density and commercial code requirements. Call (707) 791-5552 for an exact number.
Who is responsible for electrical rewiring costs — the landlord or the tenant?
It depends on the lease and scope of work. Landlords often handle common-area circuits and shared building infrastructure, while tenants are typically responsible for their own tenant-improvement-level electrical work.
Can our business stay open during a commercial rewiring project?
In most cases, yes. Work can usually be phased by zone or scheduled during off-hours and weekends so only the specific area under work loses power while the rest of the business continues operating.
How long does commercial rewiring take?
It depends heavily on building size and complexity; a full facility rewire commonly takes several weeks. Call (707) 791-5552 for a realistic timeline after a walkthrough.
What is three-phase power and does my business need it?
Three-phase power, commonly 120/208V or 277/480V, is a commercial power distribution standard used for heavier equipment loads than typical single-phase service. Whether you need it depends on your specific equipment.
Does an older commercial building need a full rewire to meet current code?
Not always. Many older buildings can be brought into compliance through targeted upgrades addressing the systems that most directly affect safety and inspections, without full demolition.
What's the difference between commercial rewiring and tenant improvement electrical work?
Rewiring typically addresses a building's underlying electrical infrastructure, while tenant improvement (TI) electrical work is scoped to a specific tenant's leased space. The two are sometimes combined when existing infrastructure can't support a new tenant's equipment.
Do commercial electricians need additional insurance requirements?
Commercial general liability minimums are typically higher than residential, and landlords or property managers often require a certificate of insurance naming the building or management company as an additional insured. Bright Right Electric can provide this on request.
What are the risks of delaying a needed commercial rewiring project?
Outdated wiring increases liability exposure and can affect insurance standing, tenant expectations, and future inspection outcomes, and it risks unplanned downtime if a system fails unexpectedly.
How much does a commercial electrical panel upgrade cost?
Most commercial panel upgrades range from $1,500 to $5,000 or more, depending on amperage and system requirements. Call (707) 791-5552 to talk through your building's needs.

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.
