There are two ways to allocate maintenance funds. First, the maintenance funds of the whole building are used as a whole, that is, no matter which public department needs maintenance, the maintenance funds of the whole building must be borne. Second, the share of owners participating in maintenance works.

If you like the second option, the leaking exterior wall involves one portal building or two portal buildings. It will be shared by the owners involved according to the proportion of the construction area of the property certificate owned by each household to the total construction area.
