Nearly all US homes have 240V to the electric panel, and some have it for specific places in the house (though many places are almost entirely gas dryers/ovens), but you would need a special outlet run to charge your car at 240V since almost all regular receptacles are 120v. Even the heavy duty receps in garages and utility spaces are most often just 20A/120V instead of the standard 15A/120V.

Quotes for a new 240V line are often >$1K which is affordable in the context of a household improvement but not exactly pocket change.
