Electrical Panel Upgrades for Redwood City Properties
Redwood City spreads across a wider range of housing eras than almost any of its Peninsula neighbors, and that shows up directly in the panels we replace. The 1950s-60s ranches in Woodside Plaza and Farm Hills were built around 100-amp services, and the older downtown and Roosevelt homes from the 1920s-40s often still carry an original fuse box or a 60-amp service that was generous when the house was new and is undersized now. Meanwhile Redwood Shores, built out from the 1980s into the 2000s, was wired for its day but rarely with the headroom a household now needs to charge an EV in the garage, run a heat pump, and add a home office on its own circuit. Emerald Hills adds larger hillside homes where the load is simply bigger to begin with. Our base is in neighboring San Carlos. Call with the Redwood City address and symptoms to confirm the next available window; that distance does not guarantee an arrival time or same-day repair. We tell you honestly when a load-management device would carry the new load instead, because not every Redwood City home actually needs a full upgrade.
In Redwood City the service disconnect and reconnect runs through PG&E, and the building permit and inspection go through the City of Redwood City Building Division, which we handle for you. The mix of housing matters: Woodside Plaza and Farm Hills ranches usually have a clean exterior panel swap, while older downtown and Roosevelt homes may hide knob-and-tube or cloth wiring worth addressing at the same time. Redwood Shores sits low near the water, so weatherproofing and proper grounding of the outdoor service get extra attention. Emerald Hills hillside homes can mean longer service runs and tighter access.

Redwood City FAQ
Does a Redwood City panel upgrade go through PG&E or the city?
Both, in their own roles. PG&E disconnects and reconnects the service at the meter, while the City of Redwood City Building Division issues the electrical permit and sends an inspector to sign off. We coordinate the PG&E window and pull the city permit so you do not have to chase either one.
My Woodside Plaza ranch still has a 100-amp panel and we want an EV. Do we need 200 amps?
Often, but not always. We run a load calculation first, because some 1950s-60s Woodside Plaza homes can take an EV circuit with a load-management device and skip the full upgrade. If you are also eyeing a heat pump or induction range, a 200-amp upgrade usually makes the next install painless, so we size it for what you are actually adding.
Do the older downtown Redwood City homes need rewiring along with the panel?
Sometimes. Many 1920s-40s homes near downtown and in Roosevelt have cloth-insulated or knob-and-tube wiring behind the original panel. We check 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 move, without pushing a full rewire you do not need.
Is anything different about a panel upgrade in Redwood Shores?
Mainly the location. Redwood Shores sits low and close to the water, so we pay extra attention to weatherproof outdoor enclosures, corrosion-resistant fittings, and solid grounding. The condos and townhomes there also often share walls and have HOA rules, so we plan the work and any meter coordination around that.
How long is my power off during a Redwood City panel upgrade?
The outage window depends on the approved work, PG&E scheduling and the required Redwood City inspections. Confirm the disconnect and reconnect arrangements before the installation date, including what happens if work or inspection takes longer than planned.
What conductor and mast sizes does Redwood City expect on a 200 ampere service?
The city's Residential Electrical Service Change handout lists 2/0 copper or 4/0 aluminum conductors in the mast for 200 amperes, a 1 1/2 inch copper or 2 inch aluminum mast, a #4 copper grounding electrode conductor and a 2 inch underground feeder conduit, with the mast braced if it stands more than 36 inches above the roof and PG&E drop clearances of 10 ft over walkways, 12 ft over driveways and 18 ft over a public street.

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.
