Yeah I’d say it’s pretty normal all over Europe, it might just be a common case of Americans being weird.
The type of arrangement I’m used to, property of the building is shared among the owners of the flats, who vote on how to run it in an assembly. They also appoint (and pay for) the maintainer you spoke of, but their role is more centered on overseeing/administering the building, handling paperwork, hiring contractors and such. Also, even for very large flats you end up paying a couple hundred euros a year for their services, so it hardly compares to rent.
