That’s when governments comes in. In france every new building has to be built with planning for charging equipment to be installed by anyone requesting it. For older buildings you have the right to ask for a full installation (it will obviously cost more)

My sister lives in ND and most complexes already have outlets for each parking space for block heaters.
