Panel Upgrade Cost in San Diego County (2026)
The short version
- A 100-amp to 200-amp upgrade typically costs $2,800 to $4,200 in San Diego County when the meter and mast can stay, and $3,800 to $5,500 when they're replaced too.
- Plenty of homes don't need one for an EV charger. A load calculation decides, and a smaller charger setting or a load management device often avoids the upgrade.
- The federal tax credit for panel upgrades covered work finished by December 31, 2025. It isn't available for 2026 jobs.
Does an EV charger need a new panel?
A Level 2 charger runs on its own 240-volt circuit, and because charging is a continuous load, the circuit is sized at 125% of what the charger draws. A 48-amp charger needs a 60-amp circuit; a 32-amp charger needs 40 amps; a NEMA 14-50 outlet sits on a 50-amp breaker.
Whether your service can carry that is answered by a load calculation, which adds up what the house actually uses. It isn't answered by the number on the main breaker or by empty slots in the panel. Plenty of 100-amp and 125-amp homes pass. Homes that already run an electric range, an electric dryer, central air and pool equipment often don't. SDG&E itself notes that many customers add EV charging without a panel or service upgrade.
Ways to avoid the upgrade
- Turn the charger down. Most Level 2 chargers can be set below their maximum; a Tesla Wall Connector goes as low as 12 amps. At 32 amps a charger still adds around 30 miles of range an hour.
- Add load management. A load management device watches the whole house and slows or pauses the charger when the oven, dryer and air conditioning are running at once.
- Ask about a meter socket adapter. SDG&E lists these as one way to add certain loads, EV chargers among them, without a full panel upgrade.
- Two cars, one circuit. Chargers with power sharing, such as two Tesla Wall Connectors, split one circuit between both cars.
Our load management installations run $1,200–$2,600, which is usually far less than a new service.
What a panel upgrade costs
| Job | Typical range |
|---|---|
| 200-amp panel, existing meter and mast reused | $2,800–$4,200 |
| 200-amp panel with a new meter and mast | $3,800–$5,500 |
| 200-amp panel moved to a new spot (trenching, conduit) | $5,000–$7,500 |
| 400-amp service | $7,500–$12,000+ |
| Replacing a Federal Pacific or Zinsco panel | $3,200–$5,800 |
| Subpanel for a garage or ADU | $1,400–$2,800 |
| Added if the meter, mast or grounding needs replacing | $800–$2,200 |
| Added for an underground service repair | $400–$1,200 |
| Permit, depending on the city | $150–$400 |
Our panel upgrades run $2,800–$6,500, and you get one fixed price after we've seen photos of your panel and meter. A bid far below these ranges usually leaves out the permit, the SDG&E coordination or the grounding work.
What moves the price
- Whether the existing meter, mast and grounding can stay.
- Overhead or underground service. Underground services sometimes need conduit or connection repairs as part of the job.
- How far the panel sits from the meter, and whether it has to move.
- Stucco and drywall around the panel, which have to be cut and patched.
- Panels known to fail, such as Federal Pacific and Zinsco, which come out regardless of capacity.
Near the coast, salt air corrodes outdoor meter and panel equipment faster than inland. In Coronado, Imperial Beach, La Jolla, Del Mar, Solana Beach, Encinitas, Carlsbad and Oceanside, it's worth having the meter base and service connection checked for corrosion before you get a price.
SDG&E's part of the job
SDG&E cuts power at the meter on the day of the swap and turns it back on once the new work passes the city's inspection. Service upgrade requests start in SDG&E's My Project Center.
SDG&E runs an Express Program for some service upgrades, but only for jobs that add no load to the home, keep an overhead service on the same wall, and stay at or below 400 amps; underground relocations don't qualify. An upgrade made so you can add an EV charger adds load, so it goes to a regular SDG&E planner and is handled in order of application date.
Locally, expect one to three weeks from signing for the permit and SDG&E's scheduling, and four to eight hours without power on the day of the swap.
If you're also replacing gas appliances with electric ones, SDG&E's Common Facility Cost Treatment can lower your share of service upgrade costs; SDG&E checks eligibility with an attestation form. SDG&E also points to GoGreen Financing and On-Bill Financing for qualifying electrification work.
Incentives in 2026
- Federal panel credit (25C): 30% of the cost, up to $600, for a 200-amp-or-larger panel installed alongside qualifying efficient equipment. It covered work purchased and installed through December 31, 2025.
- Federal EV charger credit (30C): ended for chargers installed after June 30, 2026.
- Income-qualified programs: these open and close with funding. SDG&E's Customer Home Electrification Readiness Program (CHERP) helps households find what they qualify for.
Permits, city by city
A panel upgrade needs an electrical permit from your city, or from the County outside city limits, and an inspection before SDG&E restores power. How each office takes applications, from our permit research checked in October 2026:
