Hello and welcome!
In models with removable batteries, the primary intent is to allow a quick swap during enduros and races. I don't believe it's practical to carry 38 kg (84 lb) in and out on a regular basis in order to use an external charger as the only means of charging.
Moreover, the batteries probably should not be taken indoors, let alone charged indoors.
I'm not sure there's a good solution to this problem, other than working with the building management to see if an outlet can be made available, or charging at another location.
