In North America? Good luck! Part of what got me to buy a smallish industrial building
was needing three phase. It's usually cheaper/easier to either use a VFD if it's
for motor equipment, or a rotary converter, than trying to get the power company to give
you three phase. Even if it's literally on the pole behind your house, they want $LOL
to make the connection.
Availability depends on your utility and location. It's not uncommon
for a farm to have 3-phase service--it's needed for things like hay dryers.
For example, here's my rural electric co-op's rate sheet for 3-phase
service:

By way of comparison, here's their single-phase general-service rate sheet:

The real sting is for 3-phase electric vehicle charging stations:

In my rural location, 3-phase 11KV buried is available at a disconnect
box at the street--single phase is buried along the driveway and
terminates at a transformer on a pad in my front yard. Buried 240/120V
single-phase 200A service then goes to the house.
