How do you own a condominium?

Answer 1

You own a condominium according to its boundaries. For example, in a building, the boundary may be 'from the paint, in' and this means that you own the unit and the association owns everything else. As an owner of a unit, you also own a percentage of everything else -- roofs, walls, roadways, amenities, etc., according to your allocated interest, which is determined by the association ownership share represented by your unit.
