What a photograph can settle
More than most people expect. The make and vintage of a service panel is legible from the label inside the door, and it decides a great deal: a Federal Pacific Stab-Lok or a Zinsco panel is a known problem regardless of what else is going on, and a fuse box still in service in a Willow Glen bungalow tells you the branch circuits behind it are older than the appliances plugged into them. A scorched receptacle photographs unmistakably. Two-prong outlets say there is no equipment ground. A double-tapped breaker — two wires under one screw — is visible from the room side once the panel door is open.
What a photograph cannot settle is anything intermittent. A breaker that trips once a fortnight, a light that dims only when the dryer starts, a receptacle that works until it does not — those are measurements, not pictures, and the honest answer is a diagnostic visit rather than a number invented at a distance. When that is the case we say so instead of guessing, because a range that ignores the unknown is not a favor to anyone.
The three calls that come in most
A dead outlet, or a whole wall of them. Usually one of three things: an upstream GFCI that tripped and is not where anyone would look for it, a back-stabbed connection that finally let go, or a loose neutral in a daisy chain. The fix is contained, and the diagnosis is most of the work.
A breaker that keeps tripping. The question is whether it trips on one appliance or at random. The first is a circuit doing its job against a load it was never sized for — a bathroom heater, a window unit, a garage freezer sharing a kitchen circuit. The second is a fault, and it is not a wait-and-see item.
Not enough panel. This is the San Jose call of the last few years. A homeowner adds an EV charger, a heat pump, an induction range or an ADU, and discovers the question is not the appliance but the service: a 100-amp panel with no spare spaces is a project before it is an upgrade, and it comes with a city permit and an inspection.
Permits, in one paragraph
San Jose requires an electrical permit and an inspection to replace or upgrade a main service panel — and, helpfully, no plans for a straight residential panel upgrade. New circuits and Level 2 EV charger installations are permitted work too. Swapping a device for the same kind of device — a switch for a switch, a receptacle for a receptacle, a fixture for a fixture — generally is not. If your address sits in one of the unincorporated county islands inside the city, Burbank or the Cambrian Park pocket among them, the permit is the County's rather than the city's, and people find that out at the worst possible moment. The cost guide goes through all of it, with what the city charges and how to check which jurisdiction you are in.
When to stop reading and pull the breaker
If you can smell burning, if a plate or a plug is hot to the touch, if there is a scorch mark or a buzz you can hear from across the room: switch that circuit off at the panel and stop using it. Smoke, heat inside a wall or an arc you can see is a 911 call, not a form submission. Photographs afterwards, from a safe distance, are welcome — and please do not take the cover off a panel to get one. The door open is plenty; the label inside it is what anyone needs to read.
Where this covers
San Jose proper, neighborhood by neighborhood — Willow Glen, the Rose Garden, Naglee Park, Japantown, Cambrian, Almaden Valley, Blossom Valley, Santa Teresa, Evergreen, Silver Creek, Alum Rock, Berryessa, North San José and Alviso — and the towns that share its building stock and its trade rates: Campbell, Santa Clara, Sunnyvale, Cupertino, Saratoga, Los Gatos and Milpitas. The service-area page says what that list means in practice, including which addresses are answered by the County instead of the city.
What you get back
A description of the likely cause in the order of probability, what a job of that kind involves, whether a permit applies, and a cost range with the reason for its width. Not a quote: nobody can price what they have not opened, and a number that pretends otherwise is a number that changes on the day. If the photos show something that needs to be dealt with today, that is the first line of the reply rather than a footnote.
Prices quoted anywhere on this site are ranges published by licensed electricians working in San Jose and by cost surveys, gathered as market context. They are not our quotes. Permit rules cited come from the City of San José Building Division and change from time to time — check with the Permit Center before committing to work.
Repair or Replace?
Most calls are one of two situations, and the photos usually say which. It matters because the second kind is a project with a permit and an inspection, not an afternoon.
Usually a contained fix
- One dead outlet or switch while the rest of the room works
- A GFCI that trips and resets, or won't reset
- A light fixture that flickers or hums on one circuit
- A breaker that trips only when one appliance runs
- A loose or scorched receptacle behind a plate
Usually a larger job
- A panel that is full, or a fuse box still in service
- Aluminium branch wiring, or two-prong outlets with no ground
- Repeated tripping across several circuits at once
- Added capacity — EV charger, heat pump, subpanel, new kitchen
- Anything that has burned, smoked or melted
