What Does an Electrical Panel Upgrade Cost in Fresno? (2026)
Most Fresno homeowners pay between $2,000 and $4,500 for a 100-amp to 200-amp panel upgrade in 2026. That price includes the panel, breakers, labor, permit, and inspection. A like-for-like panel swap runs $1,500 to $3,000. Complex jobs, such as a new service entrance, underground service, or a panel relocation, can reach $5,000 to $7,500.
These figures combine 2026 national cost data from Angi and HomeAdvisor with Central Valley labor rates and City of Fresno permit requirements. Five factors decide where your project lands in that range.
2026 Panel Upgrade Price Ranges (Fresno Area)
| Job type | Typical installed cost | Notes |
|---|---|---|
| Panel replacement, same amperage | $1,500-$3,000 | Swaps an unsafe or failed panel; no service change |
| 100A to 200A upgrade | $2,000-$4,500 | The most common job in Fresno's pre-1990 homes |
| Subpanel installation | $650-$1,500 | Adds capacity for additions, shops, and ADUs |
| Meter/main combo replacement | $2,500-$5,000 | Needed when the meter base is failing too |
| Heavy-up (service entrance replacement) | +$1,000-$3,000 | New mast/riser or underground lateral; PG&E coordination |
| Whole-home surge protector (add-on) | $200-$500 | Cheap insurance during any panel job |
| Permit + inspection | $100-$400 | Required in Fresno; legitimate contractors include it |
Watch out for quotes with no permit. An unpermitted panel upgrade can void your homeowner's insurance and complicate a future sale. It also skips the independent inspection that confirms the work is safe.
The 5 Factors That Set Your Price
- Amperage. Moving to 200 amps costs more than swapping a 100-amp panel, because the service entrance cable, meter base, and grounding system must meet 200-amp spec as well.
- Overhead vs. underground service. Overhead service uses a mast and weatherhead, which keeps the job simple. Underground service can require trenching or a new lateral from PG&E, adding cost and weeks.
- Panel condition and location. Rusted meter bases, panels in closets (no longer code-compliant locations), and stucco that needs patching all add labor hours.
- Current NEC safety requirements. California's electrical code requires AFCI and GFCI protection on far more circuits than older panels had. Combination AFCI breakers cost more per circuit, and they earn it: they detect the arcing faults that standard breakers miss.
- PG&E coordination. A true service upgrade means PG&E disconnects and reconnects power at the meter. Scheduling adds 1 to 3 weeks even though the on-site work takes one day.
100 Amp vs. 200 Amp: What Your Fresno Home Needs
Fresno's median home was built around 1980, according to U.S. Census housing data. A 100-amp panel served that house well in 1980. The same house in 2026 runs much heavier loads:
- Central air conditioning: 30 to 60 amps
- EV charger: 40 to 60 amps
- Electric range or double oven: 40 to 50 amps
- Electric dryer: 30 amps
- Pool, spa, or workshop equipment
- A planned ADU, addition, or electric conversion of gas appliances
Two of those loads together can max out a 100-amp panel. A licensed electrician can settle the question with a load calculation. We include one free with every panel estimate.
When Replacement Is the Only Option
Some panels should be replaced at any amperage:
- Federal Pacific (Stab-Lok). Installed in millions of homes through the 1980s. Independent testing found their breakers can fail to trip during an overload, which is the failure that starts electrical fires. Many insurance carriers now refuse to write or renew policies on homes with FPE panels.
- Zinsco. Same era, with documented failure-to-trip and bus-bar melting problems.
- Fuse boxes. They can be safe when maintained, but insurers treat them as red flags and they cannot support modern loads.
- Any panel with rust, scorch marks, buzzing, or a warm cover. Those symptoms mean failure is already underway.
Frequently Asked Questions
Do I need a permit for a panel upgrade in Fresno?
Yes. The City of Fresno requires an electrical permit and a final inspection for panel work, and Fresno County requires the same outside city limits. The inspector protects you, the homeowner, by verifying the work. A quote that skips the permit to save money is a red flag.
How long does a panel upgrade take?
On-site work takes 4 to 8 hours, with power off most of that day. Jobs that involve PG&E coordination or a new service entrance run 1 to 3 weeks from permit to final inspection.
Will upgrading my panel lower my electric bill?
Not directly. Panels draw no meaningful power themselves. You gain capacity to run modern appliances and breakers that trip when they should. Replacing an FPE or Zinsco panel can also restore your insurance eligibility.
Should I upgrade to 200 amps before installing an EV charger or new AC?
In most cases, yes. EV chargers draw 40 to 60 amps and central AC draws 30 to 60. Adding either to a maxed-out 100-amp panel means tripping breakers at best and overheated wiring at worst. Upgrade the panel first. Doing the work once costs less than doing it twice.
