(1) A declarant and any dealer warrants to a purchaser of a condominium unit that the unit will be in at least as good condition at the earlier of the time of the conveyance or delivery of possession as it was at the time of contracting, except for reasonable wear and tear and damage by casualty or condemnation.

(2) A declarant and any dealer impliedly warrants to a purchaser of a condominium unit that the unit and the common elements in the condominium are suitable for the ordinary uses of real estate of its type and that any improvements made or contracted for by such declarant or dealer will be:

(a) Free from defective materials;

(b) Constructed in accordance with engineering and construction standards, including applicable building codes, generally accepted in the state of Washington at the time of construction; and

(c) Constructed in a workmanlike manner.

(3) A declarant and any dealer warrants to a purchaser of a condominium unit that may be used for residential use that an existing use, continuation of which is contemplated by the parties, does not violate applicable law at the earlier of the time of conveyance or delivery of possession.

(4) Warranties imposed under this section may be excluded or modified as specified in RCW 64.90.675.

(5) For purposes of this section, improvements made or contracted for by an affiliate of a declarant are made or contracted for by the declarant.

(6) Any conveyance of a condominium unit transfers to the purchaser all of a declarant's or dealer's implied warranties of quality.

(7)(a) In a proceeding for breach of any of the obligations arising under this section, the purchaser must show that the alleged breach has adversely affected or will adversely affect the performance of that portion of the unit or common elements alleged to be in breach. Nothing in this section limits the ability of a board to bring claims on behalf of two or more unit owners pursuant to RCW 64.90.405(2)(d).

(b) To establish an adverse effect on performance, the purchaser is required to prove that the alleged breach:

(i) Is more than technical;

(ii) Is significant to a reasonable person; and

(iii) Has caused or will cause physical damage to the unit or common elements; has materially impaired the performance of mechanical, electrical, plumbing, elevator, or similar building equipment; or presents an actual, unreasonable safety risk to the occupants of the condominium.

(8) Proof of breach of any obligation arising under this section is not proof of damages. Damages awarded for a breach of a warranty arising under subsection (2) of this section are the reasonable cost of repairs. However, if it is established that the cost of such repairs is clearly disproportionate to the loss in market value caused by the breach, damages are limited to the loss in market value.
