(a) General rule.--Except to the extent provided by the declaration, subsection (b), section 4313(g) (relating to insurance) or 4321(g) (relating to limited equity cooperatives), the association is responsible for maintenance, repair and replacement of the common elements, and each proprietary lessee is responsible for maintenance, repair and replacement of his unit. Each proprietary lessee shall afford to the association and the other proprietary lessees 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 units through which access is taken, the proprietary lessee responsible for the damage, or the association if it is responsible, is liable for the prompt repair thereof.

(b) Rights and liabilities of declarant.--In addition to the liability that a declarant as a proprietary lessee has under this subpart, the declarant alone is liable for all expenses in connection with real estate subject to development rights. No other proprietary lessee and no other portion of the cooperative 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.
