What drives electrical panel upgrade cost
- Target amperage: Going from 100 to 200 amps (or higher) means a bigger panel and often a new service entrance.
- Panel location & access: A cramped or far-from-the-meter location makes the job slower and pricier.
- Service entrance: Upgrading the mast, meter, and utility connection adds cost beyond the panel itself.
- Code corrections: Older homes often need grounding, bonding, or circuit fixes to pass inspection.
- Permits & labor: An electrical permit, utility coordination, and licensed-electrician rates drive much of the total.
Fontana cost factors
California's Inland Empire and high desert see hot, dry summers that make air conditioning and sun-resistant roofing priorities. Labor runs a little above the national average — below the coast — and projects still fall under California's permitting and energy rules.
