Owners are responsible for the finished surface of the interior wall of the outer shell inward, and all connections to the utilities from the service entrance inward (see CC&Rs for exact definition). The association is responsible for everything else. If you notice a problem with the unit buildings or the common buildings or common area, please let us know! So roof leaks-> association, broken railing -> association, water pipe leak-> owner, though we’ll help get the water turned off to minimize the damage.
