Electrical Panel Upgrade Cost in California

A panel upgrade in California costs more than the national average — and takes longer, thanks to utility coordination requirements that don't exist in most other states. If you've received a quote and want to know whether it's reasonable, or you're budgeting before getting your first estimate, this guide gives you the honest California picture: what the work costs, what the permit process involves, and what money is available to offset it.

Most California homeowners pay $2,500–$4,500 for a standard 100-amp to 200-amp upgrade. Bay Area and Los Angeles jobs tend toward the top of that range, and prices have moved up since mid-2025 — quotes from a year ago are likely out of date. If you're an SCE customer upgrading to support an EV charger, there's an active rebate worth up to $4,200 that most homeowners miss — details below.

What California homeowners pay

The table below reflects 2026 pricing across California markets. Costs are all-in: labor, the new panel and breakers, permit fee, and utility disconnect/reconnect coordination. They do not include meter base replacement, service entrance conductor replacement, or panel relocation — those add cost when needed.

These ranges are meaningfully higher than most national cost guides because California has above-average electrician labor rates — licensed C-10 contractors in the LA metro run roughly 14% above the national average, and Bay Area rates are higher still. Material costs have also risen sharply: copper wire and cable is up substantially since 2020, and Section 232 tariffs that took effect in August 2025 pushed costs up again. If you have a quote from 2024 or early 2025, ask the contractor to re-quote — copper costs are up and the new surge protector requirement wasn't in older estimates.

What drives the cost higher here

Several things push California panel upgrades above what you'd pay in most other states.

Labor market. California's licensed electrician labor market is tight. A C-10 electrical contractor license is required for this work — the California Contractors State License Board (CSLB) enforces this — and the supply of licensed contractors in high-demand markets like the Bay Area and Los Angeles can't keep pace with demand driven by EV charger and solar installations. Electricians who specialize in panel upgrades in these markets price accordingly.

Older housing stock. California has a large number of homes built in the 1940s–1970s, many of which are still running 100-amp panels. Upgrading these often involves additional work beyond the panel itself: outdated aluminum branch wiring, grounding electrode systems that need updating to current code, or the thick cables running from the utility connection into your panel that have to be replaced because they can't handle the new amperage. Each of those adds to the quote.

The 2025 California Electrical Code. As of January 1, 2026, every panel replacement in a California dwelling must include a hardwired surge protector wired directly into the panel. This is a new requirement under the 2025 CEC that wasn't in the prior code cycle. The device itself costs $100–$250, and labor to install it adds more. Some contractors include it in their base quote; others don't. Confirm it's covered.

Underground vs. overhead service. Homes with underground service feeds are significantly more expensive to upgrade than those with overhead drops. You can tell which you have by looking at where the wire enters your home — if a cable runs down from a pole to your roof or meter, you have overhead service; if there's no pole connection and the wire comes up from the ground, it's underground. If your service enters the home underground and the lateral needs to be replaced or extended, expect trenching costs, sidewalk permit fees, and extended PG&E coordination timelines on top of the standard job cost. One San Francisco contractor estimated about $5,500 for a basic overhead 200-amp upgrade and around $18,500 for an underground conversion on the same type of home.

If you're adding an ADU, the panel upgrade often comes bundled with a subpanel for the new unit — a separate cost on top of the main panel work. See the sub-panel vs. panel upgrade guide for how that decision breaks down.

Permits: what to expect

Every panel upgrade in California requires an electrical permit. There are no exceptions — even a same-brand, same-amperage panel swap requires one, because the inspector has to verify the new panel is installed safely before power is restored.

Your licensed electrician pulls the permit in their name, not yours. You don't file anything with the city. What varies significantly across California is what the permit costs and how long it takes to issue.

Permit fees vary widely by jurisdiction — from around $100–$150 in some LA County unincorporated areas to $650 or more in cities like Oakland and Sacramento. A few Bay Area municipalities require full plan review for service upgrades, which can add days to the process. Most Southern California cities issue permits for straightforward residential upgrades quickly, and some offer over-the-counter permits that can be obtained the same day.

The timeline from permit application to passing inspection is typically one to three weeks for a standard residential 200-amp upgrade. That window is driven more by how quickly the utility can schedule the disconnect/reconnect than by permit processing. The electrical work itself takes one day.

One 2026 code note worth flagging: California AB 2221 and subsequent regulations simplified permitting for service upgrades from 100A to 200A in many jurisdictions, and over-the-counter permitting is now available in more cities than it was a few years ago. Ask your contractor upfront whether your city offers over-the-counter permitting for your specific upgrade — if so, the permit timeline drops from weeks to days. If they tell you it's taking two weeks to process, it's worth asking whether they've explored that path.

Utility coordination: PG&E, SCE, SDG&E

This is the piece of a California panel upgrade that surprises homeowners most — and the piece most online cost guides barely mention.

Because the meter and service drop belong to the utility, not you, any change to your electrical service requires your utility to be involved. Your electrician coordinates with them separately from the city permit, typically by submitting a service change application through the utility's portal. The utility reviews the request, confirms the service can support the new panel size, schedules the disconnect before work begins, and schedules the reconnect after the inspection passes.

The three major California investor-owned utilities handle this differently:

PG&E (Northern/Central California). PG&E is generally considered the slowest of the three for service coordination. The distinction that matters most for your timeline: if your upgrade is a straight disconnect/reconnect at the existing meter location — no new service, no moved meter — PG&E's involvement is limited and typically adds days, not months. If the job requires a new service from PG&E (a larger drop, a relocated meter, a mast height change, or any underground work), you join PG&E's new-service backlog, which has been running six to eighteen months in much of the Bay Area in 2026. Ask your electrician upfront which category your job falls into. The key sequencing rule: submit the PG&E service change application the same day you sign the contract — not after the city permit clears — or you lose weeks waiting in line you could have spent in parallel. PG&E also has specific requirements for meter base placement and service entrance clearances that your contractor must account for in the design.

SCE (Southern California, most of LA County, Inland Empire). SCE coordinates the disconnect and reconnect window, and reconnect scheduling depends on their crew availability — it's not something your contractor can guarantee at the time of the estimate. SCE also enforces a rule that meters cannot be located under any roof overhang or structure, which occasionally requires a panel relocation when an upgrade is planned.

SDG&E (San Diego County). The SDG&E coordination process for standard residential service changes is generally more streamlined than PG&E's. Most San Diego homeowners report total project timelines of two to four weeks from signed estimate to permanent reconnect, with straightforward overhead upgrades on the faster end.

A utility service change doesn't typically add to your contractor's invoice — the utility handles the disconnect and reconnect as part of their infrastructure work.

Rebates and incentives

There's real money available to California homeowners — and most miss it. The bigger opportunity is at the state and utility level, not the federal level. The federal 25C Energy Efficient Home Improvement Credit expired on December 31, 2025 and is not available for 2026 installations.

SCE Charge Ready Home (active as of 2026). Southern California Edison's Charge Ready Home program offers rebates for panel upgrades when the upgrade is paired with a new 200-amp panel and a dedicated 240-volt circuit for a Level 2 EV charger, installed within 25 feet of off-street parking. There are two eligibility paths:

• Income-qualified: Up to $4,200 (covering up to 100% of upgrade costs) for households earning below 80% of area median income, or enrolled in a qualifying assistance program like Medi-Cal, CalFresh, or LIHEAP.
• Geographic-based: Up to $2,100 (covering up to 50% of upgrade costs) for residents in designated disadvantaged communities, as defined by the SB 535 CalEnviroScreen map — regardless of income.

As of April 2026, the program has issued over $11 million in rebates across more than 3,900 homes. It has a network of over 400 enrolled electricians who know the application requirements. You can apply at any point in the process — before work begins, during installation, or up to six months after completion. The application portal is at evhome.sce.com. This program is only available to SCE customers in single-family homes — condos and apartments do not qualify.

PG&E and SDG&E customers. PG&E does not currently offer a comparable direct rebate for residential panel upgrades. California's HEEHRA program no longer has funding available for single-family panel upgrades as of early 2026 — the initial allocation was fully reserved, with new applicants placed on a waitlist. The program is currently only accepting applications for multifamily projects. SDG&E has no comparable residential panel rebate.

TECH Clean California. This program previously offered incentives for panel upgrades paired with heat pump installations, but single-family incentives through TECH are fully reserved as of November 2025 and not accepting new reservations.

Municipal utility programs. Pasadena Water & Power offers $1,000–$1,500 for qualifying upgrades. Santa Barbara Clean Energy's HEAP offers up to $4,000 for income-qualified customers. Other municipal utilities vary — check with your specific provider. The DSIRE database at dsireusa.org is the most current source for California-specific incentive programs.

How to evaluate quotes in California

Getting three quotes is the standard advice, and it's right. But in California, what matters as much as the number is what the quote includes. A quote missing key line items can create a significant gap between the estimate and the final invoice.

A complete California panel upgrade quote should clearly state: the new panel amperage and brand, the permit fee (or a note that it will be billed at cost), utility coordination (confirm this is included), the surge protective device required by the 2025 CEC, and whether meter base replacement or service entrance work is included or excluded. If any of those items aren't named, ask.

A few California-specific items to confirm are in any quote:

• Permit fee — either included in the total or noted as billed at actual cost. Every licensed C-10 contractor pulls a permit for panel work as standard.
• Utility coordination — confirmation that the service change application to PG&E, SCE, or SDG&E is handled by the contractor as part of the job.
• Quote validity window — if copper-heavy service entrance work is in scope and the quote is valid for 90+ days, ask whether material cost changes would affect the price.
