Same-Day Service
Most Costa Mesa homes were built between the 1950s and the early 1970s. Many still run on the original 60-amp or 100-amp service. Those panels now feed EV chargers, heat pumps, induction ranges, and backyard ADUs. Our electricians measure your actual load first. Then we size the panel and service for your home and the loads you plan to add. For panel work across Orange County, see our electrical panel upgrades and replacement service.
Every estimate starts with an NEC load calculation on your home, so you pay for the panel size you need.
Our labor on every panel upgrade carries a lifetime warranty.
We file the City of Costa Mesa permit and schedule the SCE disconnect and reconnect.
Most Costa Mesa panel upgrades cost $2,500 to $6,500. Four things set your price.
Amperage. Replacing a 100-amp panel with a new 100-amp panel costs less than moving to 200-amp service. A 200-amp upgrade needs a larger meter panel, heavier service conductors, and an SCE service request.
Panel location. Many Costa Mesa ranch homes have the meter and main panel on an exterior stucco wall. A same-spot swap keeps labor down. Moving the panel adds wiring, stucco patching, and time.
Overhead or underground service. Homes fed from a pole usually need a new mast and weatherhead for a 200-amp upgrade. Homes with underground service need SCE to confirm the service line handles the larger load.
Existing wiring. Missing grounds, cloth-insulated circuits, or an outdated grounding system get corrected so the job passes city inspection.
Your free estimate lists each item before work starts. For a full price breakdown, read our guide: How Much Does a Panel Upgrade Cost in Orange County?
Costa Mesa incorporated in 1953 and built most of its housing over the next two decades. Tract homes in Mesa Verde, College Park, and Mesa del Mar date from the late 1950s and 1960s. Eastside and Westside streets mix original post-war homes with newer rebuilds. Panels in many of these homes are 50 to 70 years old.
Our electricians find these conditions most often in Costa Mesa homes. If your panel is one of the brands below, see our Zinsco and Federal Pacific panel replacement page.
A panel upgrade usually follows a new electrical load or a problem at the panel. These are the triggers we see most in Costa Mesa homes.
Southern California Edison supplies power to homes across Costa Mesa. A panel replacement at the same amperage needs a scheduled SCE disconnect and reconnect. A service upgrade, such as 100 amps to 200 amps, goes through SCE service planning before work starts.
Our office handles the SCE side for you:
Every panel upgrade in Costa Mesa needs an electrical permit from the City of Costa Mesa. For a single-family home with its own service, the city offers a Residential Panel Upgrade Insta-Permit through TESSA, its online permit system. The Insta-Permit covers the main panel, its riser, and the grounding and bonding conductors.
Work outside that scope needs its own permit. An EV charger circuit, added outlets, or solar go on separate applications. Condos, multi-meter buildings, and commercial panels go through the standard permit process.
Contractors who pull the permit need an active California contractor’s license and a Costa Mesa business license. Pelican Coast Electric files the permit, meets the city inspector, and closes the permit after final inspection.
Your load calculation picks the job. For a detached single-family home, the City of Costa Mesa Insta-Permit covers all three.
Replaces the 60-amp or 100-amp service still common in Mesa Verde, College Park, and Eastside homes. Overhead services get a new mast and weatherhead.
Swaps a fuse box or a flagged panel at the same location and amperage when your load calculation shows enough capacity.
Moves the meter panel for a remodel, an ADU, or a garage conversion. The city and SCE both approve the new spot, and the stucco patch gets a lath inspection.
Four steps, from the first visit to restored power.
Load Calculation & Site Plan
An electrician checks your panel, meter, and grounding, runs the load calculation, and maps the SCE pole or vault and the service path for the city site plan. You get a written price.
Insta-Permit & SCE Planner
We file the Residential Panel Upgrade Insta-Permit in TESSA and call the SCE service planner to set job coordination or a meter spot.
Install & Grounding
We post the permit placard where it shows from the street. SCE cuts power. Our crew sets the new panel, adds the second ground rod the city standard requires, and labels every circuit.
City Inspections & Reconnect
We upload the job documents to TESSA before the inspector arrives. The city inspects the wiring, the stucco lath on a moved panel, and the final. SCE restores power, and we walk you through the new panel.
Typical timeline: one working day on site for most Costa Mesa panel upgrades. City work hours run 7 a.m. to 7 p.m. on weekdays and 9 a.m. to 6 p.m. on Saturdays, with no Sunday work.
Answers to the questions Costa Mesa homeowners ask most before a panel upgrade.
Most Costa Mesa homes pay $2,500 to $6,500. A same-spot changeout on a 1950s or 1960s tract home in Mesa Verde or College Park sits near the low end. A 200-amp upgrade with a new overhead mast, a relocation with stucco repair, or new underground conduit moves the price toward the top. Your free estimate lists each cost before work starts.
Yes. For a detached single-family home with one meter, the City of Costa Mesa issues a Residential Panel Upgrade Insta-Permit through TESSA. It covers a changeout, an upgrade, or a relocation of the main panel. Condos, multi-meter buildings, and commercial panels go through standard plan review. We file the permit with a site plan, post the job placard, and meet the inspector.
Yes. The city standard requires a call to the SCE service planner before work starts, to set job coordination or a meter spot. SCE also signs off on any new panel location and inspects new underground service conduit. Our office makes the call and books the dates.
Most installs take one working day on site. Costa Mesa allows construction from 7 a.m. to 7 p.m. on weekdays and 9 a.m. to 6 p.m. on Saturdays, with no Sunday work. The Insta-Permit and the SCE planner come first, and a 200-amp upgrade takes longer to schedule than a same-size changeout.
Many Costa Mesa homes still run on 60-amp or 100-amp service from the 1950s and 1960s. A Level 2 EV charger, a heat pump, or a garage-conversion ADU often pushes those panels past their limit. The load calculation decides. If it shows room, a same-size changeout costs less.
Have a licensed electrician check it. Federal Pacific Stab-Lok, Zinsco, Pushmatic, and Challenger panels still turn up in Costa Mesa post-war tracts. None of these brands is made today, and replacement breakers are hard to find. Home inspectors and insurers often flag them. A same-spot changeout usually fits the Insta-Permit. See our Zinsco and Federal Pacific panel replacement page.
Yes. We answer 24/7 and offer same-day visits from the Westside to South Coast Metro for a dead panel, a tripping main breaker, or a burning smell at the panel. Call (949) 989-4404.
You get a closed City of Costa Mesa permit, a labeled circuit directory, and a panel that passed the city final. Our lifetime labor warranty covers the work, and the manufacturer warranty covers the panel and breakers.
We upgrade electrical panels in every Costa Mesa neighborhood, from Mesa Verde to South Coast Metro. For other electrical work in town, see our Costa Mesa electrician page.
