Most apartment buildings didn't have A/C when they were built either. The building I'm in is nearly 120 years old. At some point the landlord ran extra cabling and dedicated outlets so we could have window air conditioning. I imagine that was as expensive or more than car charging stations would be. The market demanded it, landlords provided it. Keep in mind landlords are in the business of finding ways to deploy capital to increase their rental incomes. That's why they upgrade kitchens and floors - because they can raise rent. Much like air conditioning once was, having an electric car charger certainly seems like an amenity you can charge for.
