We have strata, or group ownership of the land and structure of a housing complex. Each owner owns what’s inside the walls of their apartment but the strata owns rye rest and is jointly owned by all owners. Each pays a fee to cover maintenance, upkeep and a sinking fund for major repairs. It works pretty well, for the most part.

However there is quite an administrative burden and many homeowners dont want the hassle of doing the admin so the busybodies tend to do it and overstep their boundaries often. Many use an external company to manage it. The biggest company was just in the need today as it was fsvouring its own insurance product for all the buildings it manages. Conflict of interest for profit isn’t quite the joint ownership plan strata envisions.
