What a panel upgrade costs

Bay Area residential panel and service upgrades typically run $4,500–$14,000, based on our recent jobs. Where you land in that range comes down to a few knowable things — which is why we can quote a fixed price after seeing your panel:

Cost driver How it moves the price
Target amperage 100A → 200A is the most common upgrade; 225A+ or a same-size panel swap (e.g. replacing a Zinsco/FPE) sit at different points in the range
Meter / main service relocation If the meter or main service has to move, utility scope and repair work (stucco, siding) push toward the top of the range
Service entrance & access Overhead vs underground service, trenching/conduit needs, and how accessible the panel is

Range reflects our recent Bay Area jobs, before city permit fees (passed through at cost). See our published pricing — and our fixed-price guarantee: the price we quote is the price for the agreed scope.

Signs you need a panel upgrade

  • Breakers trip regularly, or lights dim when the A/C, dryer, or oven starts
  • Your home still has a 60A or 100A service with modern appliances
  • The panel is out of breaker spaces for new circuits
  • You're adding an Level 2 EV charger, heat pump, induction range, ADU, or a major remodel
  • You have a Zinsco or Federal Pacific (FPE) panel — these have documented failure-to-trip problems and should be replaced regardless of capacity
  • You're going solar or adding a battery and the panel can't accept the backfeed breaker

How the upgrade works (we handle all of it)

  1. Load calculation & fixed quote. We run the NEC Article 220 numbers (or start from your own calculation), confirm the right service size, and quote a fixed price.
  2. Permit & PG&E. We prepare the load calc, pull the city electrical permit, and schedule PG&E's disconnect/reconnect — the step that trips up most DIY timelines.
  3. Install day. The swap itself is usually one day on site; power is typically restored the same evening.
  4. Inspection. We meet the city inspector and close the permit. Done means signed off, not just powered up.

Typical end-to-end timeline in most Bay Area cities: 2–3 weeks, driven mostly by plan-check and PG&E scheduling.

Sometimes you don't need the upgrade

If your load calculation comes back close to the limit because of an EV charger, an EV Energy Management System (EVEMS) can throttle charging when the rest of the house is drawing hard — keeping you legally within your existing service for a fraction of an upgrade's cost. We'll tell you honestly which path is cheaper for your situation; it's one of the options we quote side-by-side.

Panel upgrade FAQ

How much does an electrical panel upgrade cost in San Jose and the Bay Area?

A typical residential panel or service upgrade runs $4,500 to $14,000 in the Bay Area, driven by the target amperage (100A to 200A is most common), whether the meter or main service must be relocated, and panel accessibility. City permit fees are passed through at cost. We publish our price ranges and quote a fixed price before work starts.

Do I need a panel upgrade to add an EV charger?

Not always. A Level 2 EV charger adds a large continuous load, and many older 100A services can't absorb it — but the only way to know is an NEC Article 220 load calculation. If the numbers are close, an EV Energy Management System (EVEMS) can often keep you within your existing service for far less than an upgrade. Run our free NEC load calculator to check your panel in about 3 minutes.

How long does a panel upgrade take?

Plan on 2–3 weeks end to end in most Bay Area cities: a few days for design and permit submittal, the city's plan-check time, then usually a single day on site for the swap, followed by inspection. PG&E coordination (for a service disconnect/reconnect) is the most common source of schedule variation — we handle that scheduling for you.

Do I need a permit for an electrical panel upgrade?

Yes — every Bay Area jurisdiction requires an electrical permit and inspection for a panel or service upgrade, and most require a load calculation with the application. We pull the permit, prepare the load calc, coordinate PG&E, and meet the inspector as part of every panel job.

What are the signs my electrical panel needs to be upgraded?

Frequent breaker trips, a panel that's warm or buzzing, flickering lights when large appliances start, a 60A or 100A service in a home with modern loads, no space for new circuits, or plans to add an EV charger, heat pump, ADU, or major remodel. Zinsco and Federal Pacific (FPE) panels should be replaced regardless — they have documented failure-to-trip problems.
