An electrical panel upgrade in California usually costs $2,500 to $4,500 to move a home from 100 to 200 amps, and $5,000 to $7,000 or more when the meter socket or utility service drop must also change. Every service upgrade needs a city or county electrical permit, an inspection and utility coordination, so expect weeks, not days.

Electrical Panel Upgrade in California: Cost at a Glance

Project type Typical cost Source
Breaker box replacement, Los Angeles $795 to 3,189 (average 1,990) Angi, Los Angeles
Breaker box replacement, San Francisco $795 to 3,555 (average 2,137) Angi, San Francisco (2026)
Main panel upgrade to 200 amps, California $2,500 to 4,500 NRG Clean Power (Sept. 2026)
200-amp upgrade with new meter socket or service drop $5,000 to 7,000 NRG Clean Power (Sept. 2026)
Load management device (alternative to upgrading) $300 to 700 NRG Clean Power (Sept. 2026)

Quotes vary most with whether the utility must change the service, whether the panel must move to meet clearance rules, and how much wall, stucco or trenching work surrounds it. Contractors such as Electricians Service Team, which lists its C-10 license online and focuses on 100- to 200-amp upgrades for EVs, solar and modern appliances, typically price these items separately. Before signing, compare at least one more itemized bid from licensed electricians serving California homes in your city, since permit fees and utility steps differ by jurisdiction.

Do You Actually Need a Panel Upgrade?

Not every home adding an EV charger or heat pump needs a bigger panel. Start with a licensed electrician’s load calculation under the California Electrical Code. Signs an upgrade is warranted:

  • A 60- or 100-amp service with plans for an EV charger, heat pump, induction range or electric water heater
  • Breakers that trip repeatedly under normal use, or a panel warm to the touch
  • No open breaker spaces for new circuits
  • Fuses, corrosion, scorch marks, or a panel model your home inspector flagged

If capacity is the only issue, a load management device can sometimes replace a full upgrade for far less.

The Panel Upgrade Process, Step by Step

  1. Site visit and load calculation. The electrician confirms current service size and needs.
  2. Electrical permit. The contractor applies to your city or county building department; many issue simple service-upgrade permits online.
  3. Utility coordination. When service size changes, the utility must approve and reconnect the service. In Anaheim, the city’s utility issues a “meter spot” report, typically within two to three business days, which must be on site for inspection.
  4. Installation day. Power is shut off while the old panel is replaced and the new one labeled.
  5. Inspection and reconnection. The inspector signs off, and the utility restores permanent service. Anaheim requires both an electrical service meter inspection and a final electrical inspection.

Electrical Panel Permit Fees in California: Real Examples

Permit fees are set locally, and published schedules vary widely:

City Fee item Amount
San Francisco (DBI, from Sept. 1, 2025) Residential permit, up to 40 outlets/devices, includes up to 200-amp service upgrade $534
San Francisco (DBI) Service distribution equipment, 225 amps or less, standalone $397
Anaheim Meter/switchgear under 600 volts, up to 200 amps $126
Anaheim Minimum permit fee $167

Your estimate should list the permit fee separately. Because permitted work falls outside California’s $1,000 minor work exemption, a panel upgrade must be done by a contractor holding an active C-10 Electrical license from the Contractors State License Board.

Panel Upgrade Rebates and Tax Credits in 2026

Program Status in 2026 Details
Federal 25C credit (panel upgrades) Ended Covered 30% up to $600 for qualifying panel work installed by Dec. 31, 2025; new work no longer qualifies
PG&E Rebate Plus Active (confirm with PG&E) Up to $5,000 for a panel upgrade plus EV charger installation for income-qualified customers
SCE Charge Ready Home Active (confirm with SCE) Up to $4,200 for a panel upgrade plus EV outlet for income-qualified or disadvantaged-community households

Both utility programs require EV charging, so pair the upgrade with a charger.

What Changed in 2026: The New California Electrical Code

The 2025 California Building Standards Code took effect January 1, 2026. Its electrical section, the California Electrical Code, is based on the 2023 National Electrical Code. 2026 permits are generally reviewed under these rules, so ask which edition your city enforces.

Frequently Asked Questions

How much does a 200-amp panel upgrade cost in California?

NRG Clean Power’s September 2026 estimates put a 200-amp main panel upgrade at $2,500 to $4,500, or $5,000 to $7,000 if the meter socket or service drop also changes. Permit fees, stucco or drywall repair and panel relocation add cost.

Do I need a permit to upgrade my electrical panel in California?

Yes. Panel and service upgrades require a city or county electrical permit and inspection, and the utility must be involved when service size changes. A licensed C-10 electrical contractor must perform the work.

How long does a panel upgrade take?

Installation usually takes a day, but permits, utility scheduling and inspections can stretch the project to several weeks. Jobs requiring a new service drop or meter take longest.

Is there a tax credit for panel upgrades in 2026?

No. The federal 25C credit applied only to qualifying work installed by December 31, 2025. In 2026, the main incentives are PG&E Rebate Plus and SCE Charge Ready Home, both for income-qualified households adding EV charging.

Can I avoid a panel upgrade when adding an EV charger?

Sometimes. A load management device, roughly $300 to $700, limits EV charging when other appliances run, keeping demand within your panel’s capacity. A load calculation will show whether this works for your home.

Next Step

Photograph your panel label and main breaker, list major appliances you plan to add within five years, and ask for a load calculation with each quote so you only upgrade once.
