What actually drives the cost up
- Starting panel type. Going from a modern 100-amp breaker panel to 200 amps costs less than replacing an old fuse box, which usually needs the whole enclosure and service conductors redone.
- Meter and service entrance work. If the utility’s meter base or the overhead/underground service line also needs upgrading, that adds real cost and can involve coordination with PG&E.
- Panel location and access. A panel that’s easy to reach costs less to work on than one buried in a finished wall or a tight crawlspace.
- Permit and inspection fees. Included in most quotes, but worth confirming — see the permit section below.
- What you’re upgrading for. A straight capacity upgrade is simpler than one that also adds new circuits for an EV charger, hot tub, or addition at the same time.
Permits: who handles it depends on your address
A panel upgrade requires a permit and inspection everywhere in the service area — this isn’t optional, and it isn’t just a formality: the inspection confirms the new panel and connections are actually safe before the work is closed up. Which department handles it depends on where you live:
- Inside Modesto city limits: the city’s Building Safety Division handles permits through its eTRAKiT online portal, or in person. Contact: 209-577-5232.
- Unincorporated Stanislaus County (including the Salida and Empire areas): Planning & Community Development handles it through the county’s Accela portal, which lists a specific online category for residential electrical service upgrades up to 1,000 amps. Contact: 209-525-6557.
- Ceres, Turlock, Riverbank, or Oakdale: each is its own incorporated city with its own building department — neither Modesto’s nor the county’s process applies there.

Is a full upgrade always necessary?
Not always. If you’re specifically planning an EV charger and your panel has some spare capacity, a load-management device can sometimes handle it for a few hundred dollars instead of a full panel upgrade costing thousands — see our EV charger cost guide for that comparison. And for genuinely minor electrical work — not a panel upgrade itself, which always needs a permit — California’s statewide minor-work exemption allows unlicensed work only when the total job is $1,000 or less, doesn’t require a permit, and the person doing it isn’t employing anyone else on the project. A panel upgrade doesn’t meet that bar on any of the three counts, which is exactly why it needs a licensed electrician.
Panel upgrade FAQ
How much does a 200-amp panel upgrade cost in Modesto, CA? +
A 200-amp panel upgrade in the Modesto area runs around $2,800 on the median, per 2026 industry cost data, with the total depending on your home’s existing panel size, wiring condition, and whether the meter/service entrance also needs work.
Do I need a permit to upgrade my electrical panel in Modesto? +
Yes — a panel upgrade is exactly the kind of work that requires a permit and inspection, whether you’re inside Modesto city limits or in unincorporated Stanislaus County. See our permit guide for which jurisdiction handles your address.
How do I know if I need a panel upgrade at all? +
Common signs: a fuse box or a panel rated under 100 amps, breakers that trip when you run multiple large appliances at once, or a planned project (EV charger, hot tub, kitchen remodel, home addition) that needs more capacity than your current panel has to give.
Can I upgrade my panel myself to save money? +
No — panel work in California legally requires a licensed C-10 electrical contractor except for very minor work under the state’s $1,000 exemption threshold, and a panel upgrade itself doesn’t qualify since it requires a permit. This isn’t a safe DIY project regardless of the legal question — you’re working at the point where your home meets the utility’s live service.
