I would think apartment owners would only make an investment like that in order to make money for themselves which they would do by charging their tenants for the charging using a meter of some sort.
Of course those who don’t charge would end up paying part of it anyway. For example, most apartment complexes have swimming pools because it draws in tenants. So every tenant pays even if they never use the pool.
Primarily, I was thinking of a large employer who must compete for engineers or other talent.
I'd think some of the larger apartment complexes would team up with one of the charging networks for billing purposes.
