B. For any residential rental units that have been declared a slum property by the city or town pursuant to section 33-1905 and that are in the condominium complex, the association is responsible for enforcing any requirement for a licensed property management firm that is imposed by a city or town pursuant to section 33-1906.
C. In addition to the liability borne by the declarant as a unit owner under this chapter, the declarant alone is liable for the maintenance, repair and replacement of any portion of the common elements which the declarant reserves the right to withdraw from the condominium, as long as the unit owner maintains that right.
