Very very few. Industrial parks run 480/3phase power
Residential areas have 240/120 single phase 60 hz power.
The grid in residential areas do t have 3 phase power. The cost to add that would be unaffordable.
Transformers would have to be changed out.
Not an option for residential location.
I know of a guy who installed 480/3 phase power into his house to power a huge industrial lathe that he had in his garage. They had to install a special line to his house. I have no idea what that cost him, but I’m sure it wasn’t cheap.
I'm a retired commercial building {healthcare facilities} maintenance mechanic. In general a place like a hospital, a server farm, a building reaching 4 plus stories would likely require 480 for their air conditioning unit which would likely be a Centrifugal Chill water unit requiring 150-350 plus amps in run status and 1200-1500 plus amp start up draw at 480 volts. Also some air handlers require it. I was the HVAC Tech and Electrician. Even when I was in the Navy on an aircraft carrier the Chillers {we had 10 of them 150-ton-300 ton units} were each one the single largest power consumer.
