Quick Answer: Electrical panel upgrade in the Bay Area costs $2,500–$6,000 to upgrade from 100-amp to 200-amp service, and $3,500–$8,000 for 200-amp to 400-amp (for all-electric homes with EV charging). The cost includes the new panel, breakers, labor, and permit ($300–$800 in most Bay Area cities). PG&E service upgrade (new service entrance and utility work) adds $500–$2,000 depending on location and may take 4–8 weeks for PG&E scheduling. Bay Area electricians are in high demand — budget 2–4 weeks lead time for panel upgrades. Panel upgrades are required when installing: EV chargers over 40A, heat pumps, hot tubs, or when adding a major addition.

Question: Do I need a permit to upgrade my electrical panel in the Bay Area? Yes — electrical panel upgrades always require a permit in Bay Area cities and a final inspection by the city building department. Working without a permit on an electrical panel is illegal in California and can void your homeowner’s insurance, create difficulty selling the home, and pose fire safety risks. The permit also triggers a PG&E service work order for the utility side of the connection. Most Bay Area cities turn around electrical permits in 1–5 business days for straightforward panel upgrades. Quartz Construction handles all electrical permits as part of our panel upgrade service — you don’t need to contact the city yourself.
