Panel Upgrade cost in Kearny Mesa, 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 Kearny Mesa?
In Kearny Mesa, panel upgrade runs $2,700–$4,800, with a straightforward job landing near $3,500. Kearny Mesa electrical work is almost entirely commercial and light-industrial. 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 Kearny Mesa.
Why panel upgrade costs what it does in Kearny Mesa
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

Kearny Mesa 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 Some homes just need a clean panel swap, others hide outdated grounding or a bad mast we only find once the wall is open, and that spread shows up in the quote.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.
Can you install three-phase service for a Kearny Mesa warehouse equipment add?
Yes. Three-phase service additions for warehouse and industrial equipment along the Aero Drive, Sky Park, and Spectrum Center corridors are regular work. We do the service entrance load analysis, coordinate with SDG&E on any service upgrade required, install the dedicated equipment circuits with proper breaker sizing and conductor specification, and handle the city building department permit and inspection process. Typical industrial equipment circuit install runs $2,500-$8,500 per equipment hookup depending on amperage, voltage, and conduit routing.
My Kearny Mesa auto dealership needs EV charging for the service department, can you scope it?
Yes. Auto dealership EV charging install (both service-department equipment for EV service capability and customer-facing Level 2 chargers) is increasing volume in the Kearny Villa Road and Spectrum development dealership corridor. We do the service entrance load analysis, coordinate with the dealership on stall count and equipment specification, install the dedicated circuits with proper conduit infrastructure for future expansion, and handle the commercial SDG&E rebate paperwork. Typical dealership EV install runs $25,000-$95,000 depending on stall count and service capacity.
