(a) A judicial proceeding for breach of any obligation arising under section 76-887 or 76-888 must be commenced within four years after the cause of action accrues, but the parties may agree to reduce the period of limitation to not less than two years. With respect to a unit that may be occupied for residential use, an agreement to reduce the period of limitation must be evidenced by an instrument executed by the purchaser.
(b) Subject to subsection (c) of this section, a cause of action for breach of warranty, regardless of the purchaser's lack of knowledge of the breach, accrues:
(1) as to a unit, at the time the purchaser to whom the warranty is first made enters into possession if a possessory interest was conveyed or at the time of acceptance of the instrument of conveyance if a nonpossessory interest was conveyed; and
(2) as to each common element, at the time the common element is completed or, if later, (i) as to a common element that may be added to the condominium or portion thereof, at the time the first unit therein is conveyed to a bona fide purchaser, or (ii) as to a common element within any other portion of the condominium, at the time the first unit in the condominium is conveyed to a bona fide purchaser.
(c) If a warranty explicitly extends to future performance or duration of any improvement or component of the condominium, the cause of action accrues at the time the breach is discovered or at the end of the period for which the warranty explicitly extends, whichever is earlier.
