Section 515B.4-114 - EXCLUSION OR CHANGE OF IMPLIED WARRANTIES(a) With respect to a unit available for residential use, no general disclaimer of implied warranties is effective, but a declarant may disclaim liability in an instrument separate from the purchase agreement signed by the purchaser for a specified defect or specified failure to comply with applicable law, if the defect or failure entered into and became a part of the basis of the bargain.(b) With respect to a unit restricted to nonresidential use, implied warranties: (1) may be excluded or modified by agreement of the parties; and(2) are excluded by expression of disclaimer, such as "as is," "with all faults," or other language that in common understanding calls the purchaser's attention to the exclusion of warranties.
