(a) Except to the extent provided by the declaration, subsection (b), or section 3-113(h), the association is responsible for maintenance, repair, and replacement of the common elements, and each unit owner is responsible for maintenance, repair, and replacement of his unit. Each unit owner shall afford to the association and the other unit owners, and to their agents or employees, access through his unit reasonably necessary for those purposes. If damage is inflicted on the common elements or on any unit through which access is taken, the unit power responsible for the damage, or the association if it is responsible, is liable for the prompt repair thereof.
(b) In addition to the liability that a declarant as a unit owner has under this chapter, the declarant alone is liable for all expenses in connection with real estate subject to the development rights. No other unit owner and no other portion of the common interest community is subject to a claim for payment of those expenses. Unless the declaration provides otherwise, any income or proceeds from real estate subject to development rights inures to the declarant.
(c) In a planned community, if all development rights have expired with respect to any real estate, the declarant remains liable for all expenses of that real estate unless, upon expiration, the declaration provides that the real estate becomes common elements or units.
