Panel Upgrade cost in San Carlos, CA.
A 100-amp to 200-amp main service upgrade is one of the most common electrical projects in San Diego County, driven by EV chargers, heat pumps, and aging Federal Pacific and Zinsco panels. The price is mostly set by amperage, meter and mast condition, and how far the panel sits from the utility drop..
What does panel upgrade cost in San Carlos?
In San Carlos, panel upgrade runs $2,700–$4,800, with a straightforward job landing near $3,500. San Carlos sits east of Del Cerro along the north shore of Lake Murray, below Cowles Mountain, built out in the 1960s as single-story ranch tract homes. That housing mix is why local pricing sits where it does, not at a flat countywide number. Every quote is flat-rate before work starts, with no trip fee to San Carlos.
Why panel upgrade costs what it does in San Carlos
City of San Diego, La Mesa, Lemon Grove, and National City have the county's oldest, most varied housing stock, so this is the widest price spread we quote. A lot of these homes still carry Federal Pacific Stab-Lok or Zinsco panels, both flagged by insurers as fire risks, which is often the reason the upgrade gets called in the first place. Once we open the wall we sometimes find undersized grounding or a mast that needs replacing too.
- Federal Pacific Stab-Lok or Zinsco panel removal, common in homes from the 1960s-80s
- Permit and inspection through City of San Diego, La Mesa, Lemon Grove, or National City, each with its own turnaround
- Grounding and bonding often needs bringing up to current code on older homes
- Mast replacement sometimes required if the original is undersized or corroded

San Carlos panel upgrade cost questions
Why is there such a wide price range for a panel upgrade in this area?
Central San Diego has the oldest housing stock in the county. Some homes just need a clean panel swap, others hide outdated grounding or a bad mast we only find once the wall is open, and that spread shows up in the quote.
My insurance company flagged my Zinsco panel. Does that change the cost?
Not usually. A Zinsco or Federal Pacific swap is the same job as any 100A to 200A upgrade. The urgency is about fire risk and insurance non-renewal, not extra labor.
Do you remediate aluminum wiring in San Carlos homes?
Yes. Aluminum branch wiring from the 1965-73 era is common in the San Carlos ranch stock. Per UL guidance the fixes are full copper rewire or proper COPALUM crimp termination at every connection, not CO/ALR devices alone. COPALUM runs $3,500 to $6,500 depending on outlet count, and full rewire runs $10,500 to $18,000 depending on access. We inspect first and recommend the right approach.
How much does it cost to add an EV charger in San Carlos?
On most 1960s San Carlos homes the original 100-amp service needs upgrading before a 40 to 50 amp EV circuit, so we pair the two. The single-story ranch layouts here usually make for a clean run to the garage. The combined panel-upgrade-plus-EV project runs $3,800 to $5,600 with permit and SDG&E rebate paperwork.
