Electrical Panel Upgrades for Redwood City Homes

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. Fox Electric is based minutes away in San Carlos, and we upgrade these services to a modern 200-amp panel sized with a real load calculation rather than a guess, so there is room for whatever you add next. 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.

Permits & utility in Redwood City

Electrical service for Redwood City is provided by PG&E, and the electrical permit and inspection go through the local building department. We pull the permit and coordinate the PG&E service work as part of the job.

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.

Recent Project

200A Panel Upgrade — Redwood City200A Upgrade

A Redwood City homeowner needed more capacity for an EV charger and a future heat pump, but the home was still on its original 100A service. We ran a load calculation, pulled the city permit, coordinated the PG&E service window, and installed a 200A panel — every circuit relabeled and the directory typed, powered back up the same day.

Before: Original 100A service, no room to grow
After: 200A panel sized for EV + heat pump headroom
Coordination: PG&E disconnect/reconnect + city inspection handled
Outcome: Passed inspection, permit closed out for resale

Questions

Electrical Panel Upgrades in 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?

Usually one working day. Power is off while we swap the panel and PG&E handles the disconnect and reconnect, then the city inspects before final re-energization. We schedule the PG&E window ahead of time so you can plan around a single day without power.
