Well, in our neck of the woods, which is suburbia, any garage workshop activity is relegated to small scale 220 volt 15 amp supply.........you can get 3 phase for big air con, but for home workshop use it's not favoured for the 'burbs.
Any machinery causing noise, interference or mains spikes would soon be shut down.
Probably you're in the back woods or on a farm lot where you do not have neighbours adjacent etc.
Commercial activities, using heavy machinery, are usually relegated to industrial estates where noise is normal.
