California: the short answer
For a home Level 2 charger in California, budget roughly
$913 – $2,875 when your panel has spare capacity, and about
$2,788 – $7,875 if a panel or service upgrade is also required.
Higher labor rates, active permitting, and strong EV adoption tend to push California installs toward the upper end. The biggest swing is still your own site — routing distance and panel
condition — so itemize your estimate above.

These figures are indicative ranges, not quotes, and not
electrical-construction advice. Get several written, itemized estimates from licensed
electricians in California, and confirm the permit and inspection requirement with your
local authority (AHJ). A panel upgrade, long wire run, or trenching can move the total
well beyond these ranges.
