What we handle for San Jose buildings
Commercial work, sorted by the building that calls for it
Each card goes to the page that owns the scope detail. The description here is what tends to drive that call in San Jose specifically, so you can find your building before you read a service description.
Commercial service and panel upgrades
The first generation of North San Jose tilt-ups and the older Monterey Road strip retail commonly run out of service capacity long before they run out of building. This is the upstream scope when the switchgear, not the branch wiring, is the limit.
Tenant improvement electrical
Suite turnover in Downtown office and North San Jose flex space, where the incoming tenant equipment list almost never matches the panel the last tenant left behind.
Three-phase electrical
Warehouse and R&D buildings in Edenvale, North San Jose, and the Alviso industrial edge typically run 277/480V, while Downtown mixed-use and small retail typically run 120/208V. Feeders, transformers, and motor connections get sized to the service you actually have.
Restaurant and commercial kitchen
Hood and make-up air loads, walk-in refrigeration, and dedicated equipment circuits on the Alum Rock, Story Road, Japantown, and Lincoln Avenue corridors, usually inside a storefront that was never wired for a kitchen.
Commercial LED retrofit
High-bay warehouse lighting in the south and north industrial ends of the city, plus garage and back-of-house lighting in older Downtown buildings.
Parking lot and site lighting
Pole bases, feeders, photocell and time control for office campus lots off North First Street, retail centers, and industrial yards out on the Alviso flats.
Multifamily and apartment electrical
House panels, meter stacks, common-area circuits, and unit turnovers in Downtown and Berryessa apartment stock, scheduled so residents are not sitting in the dark.
Emergency commercial electrician
A tripped main, failed gear, or a dark suite in the middle of a business day. Response is the same across the city whether the building is Downtown or out on the Monterey Road corridor.
Generator and temporary power
Standby power for buildings that cannot absorb an unplanned outage, and temporary power for construction phases where the permanent service is not energized yet.
Commercial EV fleet charging
Depot and workplace charging at North San Jose campuses and logistics yards, where the real question is what the building service can carry, not what fits in the parking stall.
Commercial electrical maintenance
Scheduled maintenance and infrared thermography for San Jose facility teams who would rather find a failing connection on a Tuesday morning than during a shift.

San Jose commercial districts
The building stock decides the electrical work
San Jose is not one commercial market. A tilt-up in the Golden Triangle, a Downtown storefront with an upstairs office, a warehouse off Monterey Road, and a distribution building out toward Alviso have different services, different voltages, different tenant turnover, and different problems. This is what the building stock in each looks like.
R&D, flex, and campus office
North San Jose and the Golden Triangle
The corridor along North First Street and out toward Zanker and Trimble is tilt-up R&D and flex space, much of it built for one occupant and re-leased several times since. Services here usually run 277/480V stepped down for 120/208V convenience loads, and the electrical rooms are often shared. The work that comes out of this district is tenant improvement, added capacity for lab and process equipment, rooftop unit connections, and workplace EV charging that lands on a service already carrying a full building.
Older mixed-use, small office, ground-floor retail
Downtown San Jose
Downtown is the oldest commercial stock in the city and the most mixed. Small office over ground-floor retail, upper floors that have changed use more than once, and a steady interest in converting underused office space to residential. Services are often older, sometimes reached through an alley or a shared vault, and curb and street access is tight enough that material staging has to be planned. Expect house panels and meter stacks that were not laid out for the current tenant mix, and expect the disruptive part of the work to happen at night.
Light industrial, warehouse, older strip retail
Monterey Road corridor and Edenvale
South of Downtown the building stock turns industrial: warehouse and light manufacturing along the Monterey Road corridor and into Edenvale, mixed with older strip retail on the frontage. Three-phase distribution, high-bay lighting, compressed air and material handling loads, and yard lighting are the usual scope. Buildings in this band are old enough that the gear is frequently past its useful life while the tenant is very much still using it, which makes phased replacement the practical answer rather than a single shutdown.
Industrial and yard-heavy sites
Alviso and the north industrial edge
At the far north end of the city, out past the North San Jose campuses and toward the bay, the parcels turn industrial: larger footprints, dock doors, yard and site lighting, and racking that dictates where fixtures and circuits can go. Alviso sits low and close to the bay, so outdoor gear, site poles, and yard equipment see a harder environment than the same equipment inland, which makes corrosion at enclosures and pole bases worth inspecting rather than assuming.
Storefront retail, restaurants, and small service tenants
Retail and restaurant corridors
Alum Rock Avenue, Story Road, Japantown, and Lincoln Avenue in Willow Glen carry the small-tenant retail and restaurant stock. Tenant turnover is fast, and the electrical reality is that a storefront built for retail is regularly re-leased to a restaurant. That means hood and make-up air, walk-in refrigeration, and a set of dedicated equipment circuits landing on a panel that was sized for lights, a register, and a couple of receptacles. The capacity question gets answered before the lease, or it gets answered during construction at a much worse moment.
Permits and utilities in San Jose
Who has jurisdiction over your building, and who owns the meter
Two questions decide how a San Jose commercial job gets permitted and energized, and both get answered before anything is filed. The first is jurisdiction. Inside city limits the City of San José Building Division is the Authority Having Jurisdiction. A property in one of the unincorporated pockets in and around the city is permitted and inspected by Santa Clara County instead, even where the mailing address reads San Jose. Filing in the wrong office costs time nobody has.
The second is the review path. SJPermits.org is the City online permit portal, and its table lists which scopes a commercial or industrial building can file there. For electrical, that list is three items: receptacle and switch replacement, a service change or survey up to 400 amps, and a temporary power pole. The City qualifies the service change entry as like-for-like replacement in the same location with no alterations to exterior finishes. Every other electrical scope on that table is marked as not available online for commercial and industrial, and the City direction for those is to submit plans through Standard Plan Review. So anything that adds load, relocates gear, or builds out a suite means a plan submission, a review step, and a schedule that accounts for both. We do not quote a review duration, because it varies with jurisdiction, scope, and how complete the package is. We put the review step into the schedule at the start and tell you early if it moves.
Where a permit fee is carried as a cost line, it is carried as a range, $500 to $1,000 depending on jurisdiction, rather than a flat number, and larger commercial permits are billed by the jurisdiction on its own basis and passed through with documentation.
San Jose jurisdiction and utility split
- Inside San Jose city limits
- The City of San José Building Division is the Authority Having Jurisdiction. Our team files the electrical permit with the City and the City sends the inspector.
- Unincorporated pocket
- A property in an unincorporated pocket surrounded by the city is permitted and inspected by Santa Clara County instead, not by San Jose. Confirming this before submission avoids a filing in the wrong office.
- Physical electrical infrastructure
- PG&E owns the poles, wires, transformer, meter, and the service entrance connection. Service and meter coordination, including any disconnect and reconnect, is with PG&E.
- Generation supply
- San José Clean Energy is the city community choice aggregator and, by default, supplies the generation portion of the bill for enrolled accounts, shown as a line item on the same PG&E bill. It is not involved in hookup or meter work.
Working in an occupied building
How the work gets sequenced so San Jose stays open
Almost every commercial building our team works in is running while we are in it. A restaurant is serving, a warehouse is shipping, an office floor is occupied, and tenants are on leases that do not include an unannounced dark afternoon. The outage plan is the deliverable as much as the wire is.
The panel labels get verified before a window is promised
A Downtown suite may be fed from a house panel in a room reached through an alley or a shared vault, and a multi-tenant North San Jose flex building can have one panel feeding more suites than the door schedule suggests. Our team traces what each panel actually feeds first, so the tenants who will go dark are the ones who were told they would.
The window matches the corridor your building sits on
A restaurant on Alum Rock or Story Road, a Downtown storefront, and a multi-shift warehouse off Monterey Road each have a different cheapest hour to lose power, and none of them is the same hour. We set the disruptive tie-in against your operating pattern and carry it in the written scope up front instead of adding it later as a change. Where nothing can be de-energized at all, what stays live is documented in advance and worked under NFPA 70E practice, which is covered on the commercial hub.
PG&E scheduling is part of the window, not a footnote
Anything reaching the meter, the service entrance, or the utility side of a San Jose building needs the PG&E disconnect and reconnect lined up with our crew and with the City or County inspection that has to clear before the building comes back. Those are three separate calendars and we sequence them together. We do not promise a utility date we do not control.
Downtown access is arranged, not discovered on the night
Curb frontage, alley approach, freight elevator hours, and after-hours building access in Downtown San Jose belong to the property manager, not to us. Access and staging get confirmed while the window is being set, because a crew that cannot get gear to the electrical room at 10pm on a Saturday has lost the window and the tenants were notified for nothing.
The general rules our crew works to on any commercial job, outage planning, phased cutovers, temporary power, and energized-work practice, are set out on the commercial hub. This section is what changes about them inside San Jose.

What a San Jose facility team gets from our crew
We identify the right AHJ first
City of San José or Santa Clara County, confirmed against where the building actually sits before anything is submitted.
Capacity is checked against the building you actually have
A North San Jose flex suite that has turned over three tenants and a Downtown storefront on an older shared service hide their capacity problems in different places. The existing service, switchgear, and feeder get assessed against your real equipment list before the scope is set, because if the building cannot carry the load that is a landlord conversation and it belongs before construction.
The written scope carries the San Jose milestones
Scope, exclusions, the City or County submission and inspection milestones, and the outage windows, in writing, so a facilities lead or a finance approver has something concrete to sign against and knows which dates depend on a review office rather than on us.
Our own crew holds the night window
Service and switchgear, three-phase distribution, tenant improvement, and lighting are performed by our own crew, so a 10pm Saturday cutover in an occupied San Jose building does not depend on a sub layer showing up on a schedule we do not control.
Local to the county, not a national queue
Our shop is in Morgan Hill, roughly 20 miles south of Downtown San Jose on Highway 101. Calls land with our team here, not in a national queue.

Common questions
San Jose commercial electrical: FAQ
My address says San Jose. How do I know whether the City or the County pulls my permit?
A San Jose mailing address does not settle it. Santa Clara County has unincorporated pockets in and around the city where the mail reads San Jose but the parcel was never annexed, so the County permit office reviews the plans, issues the permit, and sends the inspector instead of the City of San José Building Division. That changes the submittal package and the inspection contact, and filing in the wrong office costs time nobody has. Our team confirms the parcel against jurisdiction before anything is submitted. Where a permit cost is carried in a quote it is carried as a range, $750 to $2,500 or more depending on jurisdiction and job valuation, never a flat number.
Can our electrical permit be filed online through SJPermits.org, or do we need plans?
It depends on the scope, and for commercial and industrial buildings the City keeps that list short. On the City of San José online permits table, the electrical scopes marked available online for commercial and industrial are receptacle and switch replacement, a service change or survey up to 400 amps, and a temporary power pole. The service change entry is qualified on the City table as like-for-like replacement in the same location with no alterations to exterior finishes. Everything else in the electrical table is marked as not available online for commercial and industrial, and the City instruction for those projects is to submit plans through Standard Plan Review. In practice that means anything adding load, relocating gear, or building out a suite is a Standard Plan Review job.
Does San José Clean Energy affect my meter, my service upgrade, or my shutdown?
No. San José Clean Energy is the city community choice aggregator, and for enrolled accounts it supplies the generation portion of your electricity, billed as a line item on the same PG&E bill. It is a supply arrangement, not a wires arrangement, and accounts can opt out back to PG&E generation. Everything physical stays with PG&E: the poles, the wires, the transformer, the meter, and the service entrance connection. So a service upgrade, a meter relocation, a new service, or a disconnect and reconnect for a cutover is scheduled with PG&E, and SJCE plays no part in it. The only thing that changes with your generation choice is how the supply line reads on the bill.
Can a Downtown building on a shared service be upgraded without shutting down the neighbors?
Sometimes, and the honest answer is that nobody can tell you from a photo of the panel. Older Downtown buildings vary in how the service, the meter stack, and any shared vault are actually configured, and the labels on the gear are frequently a generation out of date. What determines the answer is tracing the existing service to see what is genuinely common and what is separable, then checking whether the separable portion can ride the cutover on temporary or backfed power. That is what the site walk is for. If neighboring tenants do have to lose power, you get that in writing with a stated window before anything is scheduled, not on the night.
Our building lost power during business hours. What happens when we call?
Call 408-614-4451. Our team establishes first whether the problem is on your side of the meter or on the PG&E side, because that changes who fixes it and how fast. PG&E owns the poles, wires, transformer, meter, and the service entrance connection, so an outage upstream of the meter is a PG&E restoration. Inside the building, the usual causes are a tripped or failed main, a failed breaker or fused switch, a damaged feeder, or gear that has finally reached the end of its life. We isolate the fault, get the loads that can safely come back up running, and give you a written path for the permanent repair rather than leaving a temporary fix in place indefinitely.
We are taking over a suite in a North San Jose flex building. Will the existing panel carry our equipment?
That is the first thing to check and the most common reason a San Jose tenant improvement schedule slips. North San Jose flex and R&D space was usually built for one occupant and re-leased several times since, so the suite panel reflects whoever was there two tenants ago rather than the equipment list you are bringing. The question is whether the suite feeder and the house capacity can absorb your added load, not just whether there are spare breaker spaces. Our team assesses that against your nameplate data before the scope is written. If the answer is no, that is a base-building conversation with the landlord, and it belongs in the lease negotiation rather than in week six of construction.
