Paint on the ceiling and walls is lot owner responsibility. The actual ceiling itself is OC responsibility. OC repairs the leak. Lot owner repaints the ceiling.
I think the rule is, or used to be, that the OC was only responsible for repairing and repainting the damage done while repairing the leak. E.g. if they had to cut a hole in your ceiling to fix the leak then they would have to repair and repaint the ceiling. Otherwise, the repaint was down to the lot owner. I know it doesn’t make much sense but that’s how it used to be and perhaps still is.
