Electrical Panel Upgrades for Mountain View Properties
Mountain View runs on two very different kinds of housing, and both push us toward panel upgrades for the same reason. Old Mountain View is full of 1940s and 50s cottages, and Cuesta Park is wall-to-wall 1960s ranch homes — many of them still on the 100-amp service or the original fuse box they shipped with. That was generous when these streets were new. It runs out fast in a household charging an EV in the driveway, swapping a gas furnace for a heat pump, and cooking on induction, which is exactly the direction the neighborhoods around the Google campus and North Bayshore have been moving. The newer townhomes near San Antonio and in Whisman Station usually arrived with adequate service, so the upgrade conversation there is about the older stock in Rex Manor, Monta Loma, Gemello, and Waverly Park. A lot of those homes also hide aluminum branch wiring or knob-and-tube behind the panel, which is worth knowing about before you size a new service. Fox Electric upgrades these Mountain View homes to a modern 200-amp panel — and where a solar or battery install is on the table, a 320-amp service — sized with a real load calculation so there is genuine headroom for whatever you add next, not just enough to barely pass.
Mountain View sits in PG&E territory, so the service disconnect and reconnect is coordinated with PG&E while the permit and inspection run through the City of Mountain View building department — two separate clocks we schedule around so your power is off for as little time as possible. The older cottages in Old Mountain View and ranch homes in Cuesta Park often have the panel on an exterior stucco wall with a short meter-main run, which keeps the upgrade clean. Where solar is involved, we size the service for the interconnection up front so the panel does not become the bottleneck later.
Electrical project resources for Mountain View
Mountain View labels its searchable online permit history as covering 2000 to the present and notes that not every record appears online. Additional records may be available through the Permit Center. For a panel, rewire, or home-automation retrofit, records can identify prior alterations, but a blank search should not be treated as proof that no work occurred.
Contact the Permit Center for the applicable panel, charger, lighting, or remodel submission route.
Look up previous permitted alterations and ask the Permit Center about records absent from the online history.

Mountain View FAQ
Does a Mountain View panel upgrade go through PG&E or the city?
Both, in their own lanes. PG&E owns the meter and the service drop, so they handle the disconnect and reconnect, while the electrical permit and final inspection go through the City of Mountain View building department. Fox Electric pulls the permit and schedules the PG&E window so the two line up and your power is off for roughly a single working day.
My Cuesta Park ranch home still has a 100-amp panel and we want an EV charger. Do we need 200 amps?
Often yes, but we confirm it with a load calculation before quoting anything. On a 1960s Cuesta Park ranch that is also looking at a heat pump or induction range, a 200-amp upgrade usually makes sense so the next install is plug-and-play. If the EV charger is the only new load, a load-management device is sometimes enough and we will tell you that honestly.
We are adding solar in North Bayshore. Should the panel upgrade come first?
Usually it should. PG&E interconnection and most solar plus battery setups want a panel with enough busbar capacity to back-feed safely, and many older Mountain View services cannot. We size the upgrade — often to 200 or 320 amps — for the solar install up front so the panel does not have to be redone after the array is on the roof.
Will my older Old Mountain View cottage need rewiring along with the panel?
Sometimes. A number of the 1940s and 50s cottages in Old Mountain View have aluminum branch wiring or knob-and-tube behind the original panel. We assess it during the load walkthrough and tell you straight whether the panel upgrade stands on its own or whether addressing some of that wiring at the same time is the smarter call — no pushing a full rewire you do not need.
How long will my power be off during the upgrade in Mountain View?
The outage window depends on the approved work, PG&E scheduling and the required Mountain View inspections. Confirm the disconnect and reconnect arrangements before the installation date, including what happens if work or inspection takes longer than planned.
Do Blossom Valley ranch houses need 200 A for a heat pump and a charger?
Often, but the load calculation decides. These 1950s houses on former orchard land usually still have their original service, and adding a heat pump plus a Level 2 charger is the combination that pushes a 100 A panel past its limit. If the numbers fail by a small margin, a load management device on the charger circuit can defer the upgrade; if they fail by a lot, the PG&E Express Connect timeline of roughly five weeks becomes the schedule.
What is the long pole on a Mountain View panel upgrade?
Both the city process and PG&E requirements affect a Mountain View service change. Obtain the utility approval and field schedule, then coordinate the required city inspections and installation. Do not infer a project completion date from an average review time.

Can a 100-Amp Panel Handle an EV Charger?
A 100-amp label is a starting fact. Demand, equipment condition, circuit space, and charging needs determine the installation.
