(a) Except as limited by subsection (b) of this section, with respect to a purchaser of a unit that may be used for residential use, implied warranties of quality:
(1) may be excluded or modified by agreement of the parties; and
(2) are excluded by express disclaimer, such as “as is,” “with all faults,” or other language that implies the exclusion of warranties.
(b) With respect to a purchaser of a unit that may be occupied for residential use, no general disclaimer of implied warranties of quality is effective, but a declarant and any dealer may disclaim liability in an instrument signed by the purchaser for a specified defect or specified failure to comply with applicable law if the defect or failure was a part of the basis of the bargain.
