Electrical Panel Upgrades for Fremont Homes

Fremont is a city of five distinct districts, and a panel upgrade here means something a little different depending on which one you live in. The 1950s and 60s ranches that fill Centerville, Glenmoor, and Parkmont were almost all built with 100-amp service, and that ceiling gets hit fast once a household adds an EV charger, a heat pump, and an induction range. Niles, with its early-1900s cottages, often still carries an original fuse box or undersized panel hidden behind layers of remodeling. Up in the Mission San Jose and Mission Hills foothills, larger homes draw more load to begin with, and the climb toward the Mission Peak terrain can complicate where the meter and service entrance sit. Warm Springs is the outlier — newer developments near the Tesla factory usually already have 200-amp service, so the work there is more often a sub-panel for a garage or ADU than a full main swap. Fox Electric upgrades Fremont services to a modern 200-amp panel sized with a real load calculation, so there is genuine headroom for whatever you plug in next rather than just enough to limp along. Given how heavily Fremont leans into EVs, we plan most of these upgrades with the next charger already in mind.

Permits & utility in Fremont

Electrical service for Fremont 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.

Fremont sits in PG&E territory, so a panel upgrade here means coordinating the service disconnect and reconnect with PG&E and pulling the electrical permit through the City of Fremont building department — two separate clocks we manage so you do not have to. The district matters: Niles falls under historic-district scrutiny that can affect exterior service-entrance changes, foothill homes in Mission San Jose sometimes have long or awkward service runs, and 1950s ranches frequently hide an overloaded original panel behind a finished wall. We scope around each before quoting.

Pricing depends on your home and scope — we give a free on-site estimate with a written, fixed price before any work starts. For typical Bay Area ranges, see our guide on what a panel upgrade costs in the bay area.

Recent Project

200A Panel Upgrade — Fremont200A Upgrade

A Fremont 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 Fremont — FAQ

Does a Fremont panel upgrade go through PG&E or the city?

Both, in sequence. PG&E owns the meter and the service drop, so they handle the disconnect and reconnect, while the City of Fremont building department issues the electrical permit and sends the inspector. We coordinate the PG&E window and pull the city permit ourselves so you are not stuck chasing two agencies.

My Centerville ranch still has a 100-amp panel. Do I need 200 amps for an EV?

Often yes, but we confirm it with a load calculation before quoting an upgrade. Many 1950s-60s Fremont ranches can take a single Level 2 charger with a load-management device instead of a full upgrade. If you are also eyeing a heat pump or induction range, going to 200 amps usually makes the next install painless.

Do older Niles homes need anything special when upgrading the panel?

Sometimes. Niles cottages from the early 1900s occasionally have knob-and-tube or cloth wiring behind the original fuse box, and Niles falls within a recognized historic district, so exterior changes to the service entrance can draw extra review. We assess the wiring during the walkthrough and plan the upgrade to respect both the home and the district.

I live up in the Mission San Jose foothills. Does the terrain affect the work?

It can. Hillside homes near Mission Peak sometimes have longer service runs or a meter location that complicates the upgrade, and access for the PG&E reconnect needs planning. We walk the service path before quoting so there are no surprises on install day.

How long is my power off during a Fremont 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 in advance so you can plan around a single day without power.
