It’s essentially the same in the US for a large, multi-tenant building. Though in the US an apartment typically refers to a unit in a building with a single owner that rents the units and a condominium is a building where all the units are individually owned. In the latter case most states and/or municipalities require a condo association, much as you described, to jointly maintain the common elements of the building. Whereas in the case of an apartment building it’s much simpler as the owner of the building is responsible for all maintenance.
